DESIGNATED USE OF THE SHOVEL
This machine has been manufactured in accordance with advanced and up-to-date technology standards including recognized safety rules. Nevertheless, its use may constitute a risk to life and limb of the user or of third parties, or cause damage to the machine and to other material property. The machine must only be used in technically perfect condition in accordance with its designated use and the instructions set out in the operation manual. Only trained safety-conscious operators who are fully aware of the risks involved should operate the machine. Any functional disorders, especially those affecting the safety of the machine, should, therefore, be rectified immediately. The hydraulic Shovel is designed exclusively for excavating, i.e. excavation of bulk material and natural soil structure (e.g. earth, clay, sand and stones ashore and off-shore). Observe local and national safety regulations. Special conditions at the worksite require additional safe working precautions, follow your company's safety instructions. Short traveling distances for changing the working site are considered as part of the designated use of the Shovel. Using the Shovel for purposes other than those mentioned above (such as object handling and use as a transport vehicle) is considered contrary to its designated use. The manufacturer/supplier cannot be held liable for any damage resulting from such use. The risk of such misuse lies entirely with the user. WARNING Special use of the Shovel beyond its designated use, e.g. object handling operations, require written agreement from the manufacturer and retrofitment of the Shovel with respective safety related equipment before such special applications are permitted.

Avoid engine idling over long periods. Long periods of idling, more than 10 minutes, will not only waste fuel, but is also harmful to the engine.
z
Avoid operation against the main relief valves of the hydraulic system. Move control lever to neutral position before the loader attachment stalls due to overload.
z
Position trucks in such a way, that loading operation can be carried out in a safe and economic manner. Avoid swing angeles over 90°.
Maintenance and repair z
Preserve our environment. To prevent environmental pollution, pay careful attention to the method of disposing waste materials.
z
Always drain fluids from your machine into containers. Never drain fluids onto the ground or dump it into the sewage system rivers, the sea, or lakes.
z

LIFTING GEARS CAUTION
Heavy parts (25 kg or more) must be lifted with a hoist etc.
CAUTION If any part cannot be smoothly removed from the machine by hoisting, the following checks should be made: Check for removal of all bolts fastening the part to the relative parts. Check for existence of another part causing interference with the part to be removed.
WIRE ROPES Use adequate ropes depending on the weight of parts to be hoisted, referring to the table below:
z
Wire popes (Standard "Z" or "S" twist ropes without galvanizing) Rope diameter [mm]

CAUTION The allowable load value is estimated to be 1/6 or 1/7 of the breaking strength of the rope used.
z
Sling wire ropes from the middle portion of the hook. Slinging near the edge of the hook may cause the rope to slip off the hook during hoisting, and a serious accident can result. Hooks have maximum strength at the middle portion.
z
Do not sling a heavy load with one rope alone, but sling with two or more ropes symmetrically wound on to the load.
Fig. III-1 III-2
Version 2010/1
WARNING Slinging with one rope may cause turning of the load during hoisting, untwisting of the rope, or slipping of the rope from its original winding position on the load, which can result in a dangerous accident.
z
Do not sling a heavy load with ropes forming a wide hanging angle from the hook. When hoisting a load with two or more ropes, the force subjected to each rope will increase with the hanging angles. The table below shows the variation of allowable load (kg) where hoisting g is made with two ropes, each of which is allowed to sling up to 1000kg vertically, at various hanging angles. When two ropes sling a load vertically, up to 2000kg of total weight can be suspended. This weight becomes 1000kg when two ropes make a 120° hanging angle. On the other hand two ropes are subject to an excessive force as large as 4000kg if they sling a 2000kg load at a lifting angel of 150°.

SAFETY HINTS FOR SLING ACCESSORY WARNING
Always attend to local standards when using sling accessory.
z
Do not use rigid eye bolts from steel C 15 for lifting (e.g. ISO 580). These eye bolts may only be loaded vertically or with a maximum permissible angle of 45° to the ring.
z
Always use suitable swivel hoist rings according to local standards or Vario-Starpoint hoist rings recommended by Komatsu, see following table: Thread

DANGER Vario-Starpoint hoist rings are not suited for turning under load. After installing a Starpoint hoist ring disengage the star key. Adjust the ring plane in direction of pull before attaching any sling accessory.
DANGER Eye bolts or sling accessory which is not suitable can result in serious accidents.
z
Check that the wire rope, chains, and hooks are free from damage.
z
Always use lifting equipment which has ample capacity.Install the lifting equipment at the correct places.
z
Use a hoist or crane and operate slowly to prevent the component from hitting any other part. Do not work with any part still raised by the hoist or crane.

III.IV CONVERSION TABLE Millimeter - Inch & Kilogram - Pound Method of using the conversion table The Conversion Table in this section is provided to enable simple conversion of figures. For details of the method of using the Conversion Table, see the example given below. Example: Method of using the conversion table to convert from millimeters to inches. Convert 55 mm into inches: z
Locate the number 5 in the vertical column at the left side, take this as (A), then draw a horizontal line from (A).
z
Locate the number 5 in the row across the top, take this as (B), then draw a perpendicular line down from (B).
z
Take the point where the two lines cross as (C). This point (C) gives the value when converting from millimeters to inches. Therefore, 55 millimeters = 2.165 inches.
Convert 550 mm into inches. z
The number 550 does not appear in the table, so divide by 10 (move the decimal one place to the left) to convert it to 55 mm.
z
Carry out the same procedure as above to convert 55 mm to 2.165 inches.
z
The original value (550 mm) was divided by 10, so multiply 2.165 inches by 10 (move the decimal one place to the right) to return to the original value. This gives 550 mm = 21.65 inches.

Temperature Fahrenheit – Centigrade Conversion; a simple way to convert a Fahrenheit temperature reading into a Centigrade temperature reading or vise versa is to enter the accompanying table in the center or boldface column of figures. These figures refer to the temperature in either degrees Fahrenheit or Centigrade . If it is desired to convert from degrees Fahrenheit to Centigrade, consider the center column as a table of Fahrenheit temperatures and read the corresponding Centigrade temperature in the column at the left. If it is desired to convert from degrees Centigrade to Fahrenheit, consider the center column as a table of Centigrade values, and read the corresponding Fahrenheit temperature on the right.

General description The drive unit consists of the Komatsu engine SDA16V160, the fexible coupling, the front damper, and the PTO gear. The drive unit is bolted to the power frame with engine mounts and PTO mounts. Two damping elements, which complement each other, are installed at the prime drive in order to eliminate exessive rotation torques at the crankshaft of the engine (Fig. 2-1, Pos. 1). The damping elements are the front damper (Fig. 2-1, Pos. 3) at the front and rear side of the engine as well as the flexible coupling (Fig. 2-1, Pos. 4) which is connected to the PTO (Fig. 2-1, Pos. 5). It is very important that both damping elements are working properly. In case of any damage or wear at either the front damper or at the flexible coupling also always check the damping element at the opposite side of the engine for proper function as well. For further information about the Geislinger coupling refer to section 2.3 GEISLINGER COUPLING.

ENGINE MOUNTS
The flexible mounts are installed to absorb the vibrations and the torsional forces. They carry the total weight of the engine and the pump distributor gear with all hydraulic pumps. For this reason, all connections must be checked frequently (every 3000 hs) according to PARTS & SERVIVE NEWS "AH01521b" (latest edition), or after the engine, the coupling, or the PTO has been replaced. In the case of wear or damage of any metal rubber guide (Fig. 2-2, Pos. 1), all metal rubber guides and their fastening bolts (Fig. 2-2, Pos. 2) including nuts must be replaced. Also inspect the metal-rubber-bar (Fig. 2-2, Pos. 4) for wear or damage and replace if necessary. The bolt (Fig. 2-2, Pos. 3) should not have any axial play. If necessary, re-tighten the nut (Fig. 2-2, Pos. 5) until the rubber is squeezed slightly out of the rubber bar (Fig. 2-2, Pos. 4).

TORQUE SUPPORT
To absorb the torque force, the front engine support is additionally supported by a cup spring package. Check the cup springs (Fig. 2-2, Pos. 7) of both supports for fatigue or damage regularly and replace them if necessary. Turn the bolt (Fig. 2-2, Pos. 8) down until it slightly pre-stresses the cup spring and secure it with the lock nut. (Distance between engine torque support and bolt head "B" = 29 mm)

Description of the oil-filled GEISLINGER coupling The combination of the high elasticity of the leaf springs together with viscous damping by oil displacement ensures that the GEISLINGER-COUPLING removes major critical speeds outside the engine speed range and dampens minor torsional vibrations effectively. The widest engine speed range free of vibration periods and dangerous resonance is thus obtained. Furthermore, the employment of this coupling with its highly dampening characteristics generally results in lower stress in all engine driving shafts and gears as well as in the crankshaft, permitting further power development on standard components. In any similar application, a simple vibration damper and/or a pure flexible coupling would not confer the same advantages. The springs (Fig. 2-3, Pos. 3) together with the inner driving and outer driven member, form the chambers A and B (Fig. 2-3, Pos. A and B), which are filled with oil. If the outer member is displaced in relation to the inner member, the deflection of the leaf springs displaces oil from one chamber to the next. By this action the relative movements of the two members of the coupling are braked and the vibrations are dampened. The spacer (Fig. 2-3, Pos. 8) limits the movement of the leaf springs.

Function description From the pump (Fig. 2-5, Pos. 5.2) the oil flows through the filter (Fig. 2-5, Pos. 34.2) to the fan motor (Fig. 2-5, Pos. 23) and then back to the oil tank. The check valve (Fig. 2-5, Pos. 52) acts as an anti-cavitation valve and is installed, because the fan motor drive is stopped by a cutt-off of the pressure and the fan keeps on running for a short period due to its own torque. The hydraulic circuit "Fan drive" is secured by the pilot controlled pressure relief valve (Fig. 2-5, Pos. 31.2). This valve works together with the proportional solenoid valve (Fig. 2-5, Pos. 57K636-1). The proportional solenoid valve (Fig. 2-5, Pos. 57K636-1) operates dependent on the engine coolant temperature. The ECM (Electronic Control Module) passes the engine coolant temperature on to the MTC controller, which regulates the fan speed via proportional solenoid valve (Fig. 2-5, Pos. 57K636-1) by sending variable current signals. With a low current signal to the proportional solenoid the fans are running with the max. set-speed. With a high current signal to the proportional solenoid the fans are running with a very low speed.

1. Reduce the output flow of pump (Fig. 2-6, Pos. 5.2) by adjusting the minimum possible swivel angle, to avoid over speeding the fan: To do this, loosen both lock nuts (Fig. 2-6, Pos. 6.1+7.1) and turn out bolt (Fig. 2-6, Pos. 6) and turn in bolt (Fig. 2-6, Pos. 7) the same length. This is necessary to avoid a loose positioning pin (Fig. 2-6, Pos. 10), resulting in oscillating of the cylinder barrel. Tighten the lock nuts. 2. Remove the protection cap (Fig. 2-6, Pos. 1) from the relief valve (Fig. 2-6, Pos. 31.2), loosen the lock nut (Fig. 2-6, Pos. 2) and turn the set screw (Fig. 2-6, Pos. 3) fully clockwise and then half turn counterclockwise. 3. Isolate the function of the proportional solenoid valve (Fig. 2-6, Pos. 57K636-1), by disconnecting the plug connector, to ensure that the full flow of the pump (Fig. 2-6, Pos. 5.2) will be delivered to the fan motor. 4. Connect a pressure gauge to the check point (Fig. 2-6, Pos. M7). 5. Start the engine and let it run at high idle. 6. Check the fan speed with a non-contact rev counter, required fan speed: 1200 ± 50 rpm
WARNING Be careful not to get caught in the fan or other rotating parts.

7. If the speed can not be raised by increasing the pressure then increase the output flow of the pump (Fig. 2-6, Pos. 5.2). If necessary increase the output flow of the pump (Fig. 2-6, Pos. 5.2), by adjusting the swivel angle, until the fan speed will be 20 rpm higher than required: To do this, loosen both lock nuts (Fig. 2-6, Pos. 6.1 + 7.1), turn in the bolt (Fig. 2-6, Pos. 6), and turn out the bolt (Fig. 2-6, Pos. 7) the same length. This is necessary to avoid a loose positioning pin (Fig. 2-6, Pos. 10), resulting in oscillating of the cylinder barrel. Tighten the lock nuts (Fig. 2-6, Pos. 6.1 + 7.1).
WARNING Do not exceed the maximum permissible operating pressure of max 230 bar.
NOTE: Note down the lengths (Fig. 2-6, Pos. L1) and (Fig. 2-6, Pos. L2) as reference measurements. 8. Loosen the lock nut (Fig. 2-6, Pos. 2) of the relief valve (Fig. 2-6, Pos. 31.2), and decrease the pressure with the set screw (Fig. 2-6, Pos. 3) until the correct fan speed is obtained. 9. Tighten the lock nut (Fig. 2-6, Pos. 2) and fix the protection cap (Fig. 2-6, Pos. 3). 10. Activate the function of the proportional solenoid valve (Fig. 2-6, Pos. 57K636-1), by connecting the connector (fan speed is controlled in relation to the engine temperature). 11. Disconnect the pressure gauge from the check point (Fig. 2-6, Pos. M7). Fan speed check If the fan speed is out of the adjustment range, first increase or decrease the pressure at the relief valve (Fig. 2-6, Pos. 31.2), in order to change the speed.

Description The pump distribution gear (PTO gear) is a spur gear design and driven by a Diesel engine. The PTO gear runs in anti-friction bearings and it has been provided with a splash lubrication system. The oil supply of the bearings and tooth contacts takes place by an injection. The gearwheels are of case-hardened steel. The hydraulic pumps are directly attached to the gearbox. O-rings included in the supply enable the unit to be reliably sealed statically. The gearbox housing is a one-piece design and made of grey cast iron. The gearbox has been provided with connections for a separate cooling system or, as an option, a heating system.

Configuration, auxiliary pump drives
The gear oil in the drive shaft housings is different to the gear oil in the pump distributor gear. There are two reasons for to have seperate housings: 1. To lubricate the multi-spline connections in order to prevent wear and corrosion. 2. It makes it easier to determine a seal ring leak at one of the drive shaft connections.
Function description z
(Fig. 2-8, Pos. M): If the oil level increases, the oil drops out of the breather pipe (Fig. 2-8, Pos. 1). If this oil is gear oil, it indicates a possible leak at the gearbox side. If the oil is a mixture of gear oil and hydraulic oil, it shows a possible leak at the pump side. If during an oil level check a loss of oil is found, the cause may be worn or defective radial seal rings.
z
(Fig. 2-8, Pos. A): The oil is filled in via the oil collector reservoir (Fig. 2-8, Pos. 2). All auxiliary drive shaft housings are connected to the reservoir by pipes. The reservoir is filled approx. one half with oil. If the oil level in the reservoir increases due to leakage, the oil drops out from the breather filter (with oil level gauge) on top of the reservoir. In this case a check has to be done, to find out which one of the drive shafts seals is damaged. It can be done by disconnecting the pipe to the reservoir temporarily. Disconnect the pipe at the drive shaft housing, plug the pipe and leave the union open. Start the motor or engine and run it at high idle. After a while monitor the open drive shaft housings. The housing with continuous oil leak has a pump seal defect. Otherwise check all auxiliary drives one after the other.

Function description An external gear pump (Fig. 2-9, Pos. 8.2) feeds gear oil from the gearbox sump and pumps it through the oil coolers (Fig. 2-9, Pos. 51.1 & 51.2) back to the gearbox. The lubrication and cooling circuit is protected by a filter (Fig. 2-9, Pos. 36) and a pressure relief valve (Fig. 2-9, Pos. 29). The gear oil coolers (Fig. 2-9, Pos. 51.1 & 51.2) are small parts of the hydraulic oil cooler elements, thus the gear oil is getting cooled by the same air stream as the hydraulic oil. From the coolers the oil flows to the spray nozzle port (Fig. 2-9, Pos. P) of the gearbox via return line (Fig. 2-9, Pos. 2). The spray nozzle insures proper and adequate distribution of the oil in order to lubricate and cool down the gears and bearings. The circuit is monitored by the pressure switch (Fig. 2-9, Pos. 57B017-1). If the lube oil pressure is too low ( low volume through the coolers

Function The return oil flows into the filter chamber (Fig. 3-9, Pos. A) of the hydraulic oil tank (the drawing is showing a section of it only). The chamber is split into two sections; one section with 4 filter elements for the return oil (10 micron) and another section with one filter element for the leak oil (3 micron). But the structure of the five filter assemblies is basically the same. The hydraulic oil enters the filter at the top and then passes on its way to the tank the filter element (Fig. 3-9, Pos. 7) "Inside to outside filtration". The filter element condition is monitored by pressure switches (40B164 for the leak oil filter and 40B163 for the return oil filter). As soon as the pressure inside the filter chamber reaches the set pressure of those switches due to the restriction of the filter element, which is caused by foreign matters, the fault message ”Return oil filter restricted" or ”Leak oil filter restricted” is displayed at the VHMS monitor. In this case the filter elements must be replaced. For safety precautions the filter is equipped with a bypass valve. As the filter chamber pressure increases the by-pass valve opens at 2.3 + 0.5 bar and protects the element from bursting. But the oil does not flow totally unfiltered into the tank because it is forced to flow through the strainer (Fig. 3-9, Pos. 8).

The hydraulic oil cooling system keeps the hydraulic oil in the normal operating temperature range. Design There are four hydraulic oil coolers in front of the hydraulic tank on the R.H. side of the platform. They are in pairs mounted in one frame, one above the other. The air stream needed for the cooling is produced by hydraulic driven fans. The air flows from the inside to the outside through the coolers. For cleaning, the cooler frame must be moved to the side ("swing out cooler"). The bearing group carrier is filled with oil (CLP 220) in order to lubricate the bearings and the spline shaft connection. The oil change interval is 3000 hours.

Function description The returning oil from the system flows via the lines (Fig. 4-2, Pos. L6 - L7) into the return oil collector pipe (Fig. 4-2, Pos. 54). A pressure relief valve, also called back pressure valve (Fig. 4-2, Pos. 55) is installed on top of it. The back pressure valve (Fig. 4-2, Pos. 55) causes a back pressure which forces most of the relative hot oil through the lines (Fig. 4-2, Pos. H) to the cooler (Fig. 4-2, Pos. 39.1 - 39.2). During its flow through the coolers the oil gets cooled and then it flows through the restrictors (Fig. 4-2, Pos. 32.1 - 32.4) and the lines (Fig. 4-2, Pos. C) into the filter chamber of the main hydraulic oil tank (Fig. 4-2, Pos. 41). The restrictors are acting as shock absorbers in order to prevent cooler cracking at pressure peaks. The back pressure valve (Fig. 4-2, Pos. 55) also acts as an oil flow control valve as long as the oil temperature has not reached its normal operating temperature. During the warm up period (1/2 Qmax) the back pressure valve (Fig. 4-2, Pos. 55) is wide open because the solenoid valve 40K601 is energized. As a results smaller oil flow volume passes through the coolers, which causes the oil to reach its optimum operating temperature faster. With increasing oil temperature the oil gets thinner, so that the main pumps can be shifted to Qmax position and simultaneously the solenoid valve 40K601 will be de-energized. As a result the valve piston is more closed by the force of the spring so that a larger oil volume may pass the coolers. NOTE: Refer to the sectional drawing in (Fig. 4-3).

Function From the pump (Fig. 4-4, Pos. 5.1) the oil flows through the pressure filter (Fig. 4-4, Pos. 34.1) to the fan motors (Fig. 4-4, Pos. 37.1 + 37.2) and then back to the tank. The check valve (Fig. 4-4, Pos. 38) acts as an anti-cavitation valve. It is installed because the fan motor (driven by inertial force) keeps on running for a short period after the oil flow is interrupted by the solenoid valve (Fig. 4-4, Pos. 57K506a/b-1). The fan drive circuit is protected by the pilot controlled pressure relief valves ( Fig. 4-4, Pos. 31.1) and (Fig. 4-4, Pos. 124). These valves are working together with the solenoid valve (Fig. 4-4, Pos. 57K506a/b-1), controlled by the VHMS system, depending on the hydraulic oil temperature. z
With de-energized solenoids 57K506a-1 and 57K506b-1 the relief valve (Fig. 4-4, Pos. 31.1) is operating and the fans are running with max. adjusted speed (1250 ± 50 rpm).
z
With solenoid 57K506a-1 energized the relief valve (Fig. 4-4, Pos. 31.1) is not operating and the fans are running with a very low speed caused by the flow resistance only.
z
With solenoid 57K506b-1 energized the relief valve (Fig. 4-4, Pos. 124) is controlling the relief valve (Fig. 4-4, Pos. 31.1) and the fans are running with medium speed (1000 ± 10 rpm) only.

Description Pump type A7F0 is a variable displacement pump, designed to operate in open circuits. It has an internal case drain return into the suction port. The rotary group is a robust self aspirating unit. Changing the swivel angle of the rotary group is achieved by sliding the control lens along a cylindrical formed track by means of an adjusting screw. z
With an increase in the swivel angel, the pump output increases together with the necessary drive torque.
z
With an decrease in the swivel angel, the pump output decreases together with the necessary drive torque.
WARNING When increasing to the maximum swivel angle, there is a danger of cavitation and over-speeding the hydraulic motors!

Function description Pressure input (A) affects the main piston (Fig. 4-6, Pos. 7). At the same time pressure acts via the jet bore (Fig. 4-6, Pos. 6) onto the spring-loaded side of the main piston, and via the jet bore (Fig. 4-6, Pos. 5) onto the pilot poppet (Fig. 4-6, Pos. 9) of the relief valve cartridge (Fig. 4-6, Pos. 1). If the system pressure in line (A) exceeds the value which is set at the spring (Fig. 4-6, Pos. 2), the pilot poppet (Fig. 4-6, Pos. 9) opens. The signal for this action comes from line (A) via the jet bores (Fig. 4-6, Pos. 6) and (Fig. 4-6, Pos. 5). The oil on spring-loaded side of the main piston (Fig. 4-6, Pos. 7) now flows via the jet bore (Fig. 4-6, Pos. 5) and poppet (Fig. 4-6, Pos. 9) into the spring chamber (Fig. 4-6, Pos. 3). From here it is fed internally by means of the control line (Fig. 4-6, Pos. Y) to the tank (Fig. 4-6, Pos. B). Due to the state of equilibrium at the main piston (Fig. 4-6, Pos. 7), the oil flows from line (A) to (B), while the adjusted operating pressure is maintained. The pressure relief valve can be unloaded (remote controlled) by means of the port (X) and the function of the solenoid valve (Fig. 4-7, Pos. 124). For the operating function of the solenoid valve refer to section 4.4.3 on page 4-14.

Function description With de-energized solenoids (Fig. 4-7, Pos. 57K506a/b-1) the spool (Fig. 4-7, Pos. 3) keeps the "X" connection of valve (Fig. 4-7, Pos. 31.1) and port “B“ to port “P“ closed. The pressure relief valve (Fig. 4-7, Pos. 31.1) operates normally. • Fan speed: maximum speed. The energized solenoid 57K506b-1 operates the spool (Fig. 4-7, Pos. 3) and a connection is made between port “P“ and port “B“ and port "X" of the valve (Fig. 4-7, Pos. 31.1) The system pressure now opens the main piston (Fig. 4-6, Pos. 7) of the pressure relief valve (Fig. 4-7, Pos. 31.1), because via the solenoid 57K506b-1 (P to B) the oil from the rear side of the piston (Fig. 4-6, Pos. 7) flows from the "X"-port to the “P“ connection of the valve (Fig. 4-7, Pos. 124). The normal valve function is now remote controlled by the pressure adjusted at the valve (Fig. 4-7, Pos. 124). • Fan speed: medium speed The energized solenoid 57K506a-1 operates the spool (Fig. 4-7, Pos. 3) and a connection is made between port “P“ and port “A” and port "X" of the relief valve (Fig. 4-7, Pos. 31.1). The system pressure now opens the main piston (Fig. 4-6, Pos. 7) of the relief valve (Fig. 4-7, Pos. 31.1) because via the "X"-port the oil from the rear side of piston (Fig. 4-6, Pos. 7) flows to the tank. The normal relief valve function is eliminated. • Fan speed: minimum speed

Precaution when the fan pump was replaced: The pump must be bleeded properly and the spline housing must be filled with oil, refer to the OPERATION & MAINTENANCE MANUAL. Basic Adjustment – Maximum Speed 1. For safety reason reduce the output flow of the pump (Fig. 4-8, Pos. 5.1) by adjusting the minimum possible swivel angle, to avoid over-speeding the fan: To do this, loosen both lock nuts (Fig. 4-8, Pos. 6.1 + 7.1), turn out the torque adjustment bolt (Fig. 4-8, Pos. 6). Turn in the Qmax bolt (Fig. 4-8, Pos. 7) the same length. This is necessary to avoid a loose positioning pin (Fig. 4-8, Pos. 10) which would result in oscillating of the cylinder barrel. Tighten the lock nuts. Adjust the relief valve to a higher setting as required in order to eliminate the pressure relief valve influence. 2. Remove the protection cap (Fig. 4-8, Pos. a) from the relief valve (Fig. 4-8, Pos. 31.1), loosen the lock nut (Fig. 4-8, Pos. b) and turn the set screw (Fig. 4-8, Pos. c) fully clockwise and then a half turn counterclockwise. 3. Isolate the function of the solenoid valve (Fig. 4-8, Pos. 57K506a/b-1) by disconnecting both connectors, to ensure that the full flow capacity of pump 5.1 will be delivered to the fan motor. 4. Connect a pressure gauge to the check point (Fig. 4-8, Pos. M6).

5. Start the engine and run it at high idle. 6. Check the fan speed with a non-contact revolution counter.
WARNING Be careful not to get caught in the fan or other rotating parts.
7. Increase the output flow of pump (Fig. 4-8, Pos. 5.1) by adjusting the swivel angle, until the fan speed will be 20 - 50 rpm higher as required: To do this, loosen both lock nuts (Fig. 4-8, Pos. 6.1 + 7.1) and turn in the bolt (Fig. 4-8, Pos. 6). Turn out the bolt (Fig. 4-8, Pos. 7) the same length while the engine and the fan are in operation. This is necessary to avoid a loose positioning pin (Fig. 4-8, Pos. 10) which would result in oscillating of the cylinder barrel. Tighten the lock nuts (Fig. 4-8, Pos. 6.1 + 7.1).
WARNING Do not exceed the maximum permissible operating pressure of p = 230 +30 bar.
NOTE: Note down the lengths ”L1” and ”L2” as reference measurements. 8. Loosen the lock nut (Fig. 4-8, Pos. b) of the relief valve (Fig. 4-8, Pos. 31.1), and decrease the pressure with the set screw (Fig. 4-8, Pos. c) until the correct fan speed is obtained. 9. Tighten the lock nut (Fig. 4-8, Pos. b) and fix the protection cap (Fig. 4-8, Pos. a). NOTE: Both fans have to be checked. A speed difference of 50 rpm is normal due to the higher resistance of the air stream for the lower fan. If the speed difference between both fans is higher than 50 rpm, a possible cause could be a worn hydraulic motor or defective bearings.

General The control circuit is fed by one gear pump, and splitted in two pressure lines X4 and X2. The controlling includes the pilot pressure system and the pump regulation system. The pump (Fig. 5-1, Pos. 8.1) forces the oil through the filter (Fig. 5-1, Pos. 33) to all involved valves. The pressure accumulator ensures that under any circumstances enough pilot pressure oil is available. The accumulator (Fig. 5-1, Pos. 85) also serves as a hydraulic back-up system for a certain time when the engine was shut down, or to relieve the system pressure for repair works. The remote control valves are constantly supplied with the pilot pressure X2 (45 bar). When the operator is using the control elements, an electric signal is sent to electric system which energises and controls the relevant proportional valve(s) of the remote control valves (Fig. 5-1, Pos. 14.1/.2+15.1/.2). As a consequence of this, hydraulic oil runs to the corresponding component.

PILOT PRESSURE CONTROL (PPC) CIRCUIT
The pilot pressure oil is used for the following functions: To operate the control block spools, to supply the main pump regulation system, to lubricate the main pump bearings, to release the travel- and swing gear house brakes (spring loaded multi disk brakes), to drive the grease pumps and to supply the hydraulic track tensioning system. Function NOTE: For further details refer to the hydraulic circuit diagram! The pump (Fig. 5-5, Pos. .8.1) delivers the oil through the pressure filter (Fig. 5-5, Pos. 33) to port "A" of the pressure relief valve (Fig. 5-5, Pos. 252.2) to limit the pump support pressure X4 (60 bar). The pressure reducing valve (Fig. 5-5, Pos. 252.1) maintains the adjusted pressure of 45 bar (X2) for the pilot pressure system, the pump regulation system and the supply for some auxiliary systems. The pressure accumulator (Fig. 5-5, Pos. 85) holds a certain amount of oil under pressure to provide sufficient pilot pressure during normal operation, and to ensure a limited number of lowering operations with the main drive motor at standstill.

Function The pilot pressure oil (X2 pressure) flows via a line (Fig. 5-6, Pos. PX2) to the pressure port of each remote control valve block. These solenoid valves are energized when operating the electro proportional controls (joysticks or pedals). The soleniod valves direct the pilot pressure oil to the respective spools of the main control blocks. The pressure correlates to the deflection of the controls corresponding to the adjustments of the amplifiers and the ramp time module.

Function The electric-hydraulic control system is used to control the direction and volume of the oil flow to the operating cylinders and motors via the main control valve blocks. Hydraulically The oil volume of the pump (Fig. 5-9, Pos. 8) flows through the filter (Fig. 5-9, Pos. 9) into the pilot pressure system. The pressure is limited by the pressure relief valve (Fig. 5-9, Pos. 10). With the pressurized oil stored in accumulator (Fig. 5-9, Pos. 12), a limited number of control valve spool movements can be carried out with the main drive motor at standstill. When a lever (or pedal) is actuated, the proportional solenoid valve (Fig. 5-9, Pos. 4) and one of the directional solenoid valves (Fig. 5-9, either Pos. 5 or 6) are energized, the pilot pressure moves the spools of the main control valve blocks. Electrical Whenever a lever or a pedal is moved out of its neutral position, an amplifier will create a current between 0 and 1000 mA. (For detailed information see next page.) Depending on the lever direction, one of the directional solenoid valves (Fig. 5-9, either Pos. 6 or 7) is energized to select the main valve direction. The proportional solenoid valve alters the pilot pressure according to the lever deflection, effecting a spool movement between neutral and full stroke position.

General Function The control lever (Fig. 5-10, Pos. 1) is supplied with 24 VDC battery voltage for the switch contacts and with capacitor supported 24 VDC to create a stable signal voltage. When moving the the lever (Fig. 5-10, Pos. 1) out of his neutral position, 24 VDC battery voltage is applied to the relay (Fig. 5-10, Pos. 5) and energizes the proportional amplifier (Fig. 5-10, Pos. 4) with capacitor supported 24 VDC via terminal 1. Depending on the function of the control lever, 1 to 4 amplifiers can be involved for the „Y-axis“ (forward/ backwards direction) and 1 to 4 amplifiers for the „X-axis“ (left/right direction). The polarity of the output signal from the joystick (Fig. 5-10, Pos. 1), either positive or negative, between 0 and 10 VDC indicates the direction of the lever movement and is proportional to the lever deflection. This is the input signal to the ramp time module (Fig. 5-10, Pos. 3) at terminal 5 which will arrive after the adjusted ramp time delay via terminal 7 at the proportional amplifier (Fig. 5-10, Pos. 4), terminal 5. This input signal (between 0 and 10 VDC) is amplified to an output signal between 0 to 1000 mA and is simultaneously sent via terminal 7 (negative) or terminal 8 (positive) to the proportional solenoid valve (Fig. 5-10, Pos. 6) and the directional solenoid valve (Fig. 5-10, Pos. 7) via terminal 3 (negative) or terminal 9 (positive) to the “a” or “b”-side. The proportional solenoid valve (Fig. 5-10, Pos. 6) alters the pilot pressure (“X2”) of max. 45 bar to a value proportional to the current signal. This pressure controls the movement of the control block spool (Fig. 5-10, Pos. 8) between neutral and full stroke position.

* Alternative application The non-contacting lever control (inductive linear transmitter) contains both the electronic and mechanical components which convert the lever movement into a proportional electrical voltage. The lever can be operated in two axes: z
Axis "Y", splitted into the half axis Y- and Y + (backward and forward)
z
Axis "X", splitted into the half axis X- and X + (left and right)
Of course the lever can be moved in any combined direction (joystick function). In order to be able to monitor the direction of the lever movement and the neutral position, the electronics (Fig. 5-11, Pos. 9) sends a 24 V signal as soon as the lever gets moved out of its neutral position. For one axis two inductive linear transmitter (Fig. 5-11, Pos. 4) are used. The motion of the coil core connected to the push pin (Fig. 5-11, Pos. 5) causes a variation of the induction in the coil (Fig. 5-11, Pos. 6). The electronics converts this inductive signal into a proportional output signal of -10...0...+10 V for the amplifiers. In order to be able to monitor the direction of the lever movement and its neutral position, two switches (Fig. 5-12, Pos. 7 and 8) are fitted, which are actuated by the switch actuator attached to the push pin (Fig. 5-12, Pos. 5) as soon as the lever gets moved out of its neutral position. The monitoring of the neutral position and the direction of the lever is carried out by the MTC controller.

Set potentiometer R1 and R2 R1 for the lowest current value R2 for the highest current value
The amplifier module contains the necessary electronics for the control of two proportional solenoids. Depending on the input polarity, either channel A or channel B is operated. Both channels outputs are combined. The solenoid current (solenoid A – solenoid B) is measured and compared with the external input value. Differences between feed-back and input values, for example caused by changes in solenoid temperature or supply voltage, are compensated. Input signals up to 1 V generate no output signal (ouput current = 0). From 1 V to 9 V, the output current rises linearly from 40 mA to 350 mA. For input signals above 9 V, the ouptut current is fixed to the maximum of 1000 mA. The module also generates a direction-dependent voltage signal (solenoid A - solenoid B) as soon as the solenoid current reaches the lowest set value. Both endpoints for the linear increase (proportinal area) are set externally via the potentiometer R1 and R2. NOTE: For adjustment of the type A amplifier refer to section 5.10.2 on page 5-56.

The amplifier module contains the necessary electronics for the control of two proportional solenoids and two directional solenoids. The amplifier outputs for proportional solenoids Ax and Bx and the switched outputs As and Bs are activated by connecting a minimum of approx. 10% signal voltage at the amplifier input. A positive signal voltage controls outputs A, a negative signal voltage controls output B. A signal voltage of approx. 10% with respect to ±10 V input voltage at the amplifier, produces a stepped output voltage. The height of this 10% jumps may be set separately for the proportional outputs Ax and Bx via external potentiometers. As the signal voltage rises, the solenoid current for the proportional outputs increases linearly. A further step in the output current occurs at approx. 90% signal voltage. The maximum current or the 90% jump may be set separately for outputs Ax and Bx via potentiometers. Hence the gradient of the output curve may be influenced. LED`s indicate the current output to each proportional and switched output, whereby the brightness is approx. proportional to the solenoid current in Ax and Bx. A fault is indicated by the LED „Fault“.

General The ramp time module is snapped onto mounting rails inside the X2-box. The electrical connection is done via screw terminals. The module is operated with 24 VDC. A power supply provides the internally required positive and negative supply voltages. As soon as the power supply is in operation, the green LED (power) lights up. Internal Command Values The internal command value signal is generated from the external command value signal which is being applied to the differential input, a called-up signal and an offset signal (zero point potentiometer "Z"). The external command value signal can be changed from 0% to approx. 110% via potentiometer "G". Command Value Call-ups The call-up signals w1 to w4 also have an adjustment range of 0% to 110%. No settings required (factory set to 100%). Ramp Time Call up If the quadrant recognition is not activated, then each command value call-up "w1" to "w4" is allocated its own ramp time "t1" to "t4". As long as there is a signal change, the LED allocated to the actual ramp time is illuminated. Version 2010/1

NOTE: The adjustment of the amplifier for the swing brake is slightly different from the adjustment procedures for the amplifiers of the other foot pedals and the joysticks, also refer to section 5.10.3 on page 5-58. Adjustment procedure for the amplifier of the swing brake (foot pedal): 1. Open* the respective separating terminal (Fig. 5-17, Pos. T1) between the pedal unit and the amplifier module to be set. 2. Open* the respective separating terminal (Fig. 5-17, Pos. T2) between the amplifier module to be set and the proportional solenoid valve. 3. Disconnect the wire from the amplifier, terminal 5. 4. Connect the positive output of the service module with terminal 5 of the amplifier module using a test lead (Fig. 5-17, Pos. 2). 5. Attach a multimeter for voltage reading to the service module using test leads (Fig. 5-17, Pos. 3). 6. Attach a multimeter (in series) for ampere reading to the terminals between the amplifier module and the solenoid valve using test leads (Fig. 5-17, Pos. 3). 7. Press the swing brake pedal fully down, or manually override the relay supplying the amplifier module with 24 VDC operating voltage. (Thus, the amplifier gets 24 V operating voltage.) 8. Turn the potentiometer (Fig. 5-17, Pos. P) of the service module until the multimeter for voltage reading shows 1 VDC; the multimeter for the current reading will show a value that should correspond to the value given in the circuit diagram, e.g. 40 mA (10% value). If necessary correct the value with the potentiometer (Fig. 5-17, Pos. R1). 9. Turn the potentiometer (Fig. 5-17, Pos. P) of the service module until the multimeter for voltage reading shows 10 VDC; the multimeter for the current reading will show a value that should correspond to the value given in the circuit diagram, e.g. 350 mA (100% value). If necessary correct the value with the potentiometer (Fig. 5-17, Pos. R2). NOTE: It is important that the pilot pressure for the pressure increasing valve is 24 ±1 bar. For more information refer to section 8.3 on page 8-102. * How to open and close the terminal: Push the yellow stud (Fig. 5-17, Pos. 1) down with a screw driver and turn it 90° to the left to open or to the right to close the terminal. Then a spring pushes the stud outwards and the contacts are either open or closed.

Procedure applicable for all amplifiers except the one for the swing brake: NOTE: Used respective electric circuit diagram to identify the required terminals, components and valves. NOTE: Do not start the engine, only turn the key switch into ON-position. 1. Open* the respective separating terminal (Fig. 5-18, Pos. T1) between the lever unit and the amplifier module. 2. Open* the respective separating terminal (Fig. 5-18, Pos. T2) between the amplifier module and the proportional solenoid valve. 3. Disconnect the wire from terminal 5. 4. Connect the positive output of the service module with terminal 5 of the amplifier module using a test lead (Fig. 5-18, Pos. 2). 5. Attach a multimeter for voltage reading to the service module using test leads (Fig. 5-18, Pos. 3). 6. Attach a multimeter (in series) for ampere reading to the terminal between the amplifier module and the solenoid valve using test leads (Fig. 5-18, Pos. 3). 7. Move the lever 20S105 into operating position, or manually override the relay supplying the amplifier module with 24 VDC operating voltage. Thus the amplifier gets 24 V operating voltage. Simultaneously the power LED and either LED A(+) or B(-) light up, depending on the polarity. 8. Turn the potentiometer (Fig. 5-18, Pos. P) of the service module until the multimeter shows 1 VDC (it may be either positive or negative); the multimeter for the current reading should show a value corresponding to the value given in the circuit diagram, e.g. 300 mA (first step / 10% value [R1]). The LED’s show which channel (positiv A or negativ B) is activated. For adjustment use always potentiomenter in horizontal line to the activated LED’s. If necessary correct the value with the potentiometer (Fig. 5-18, Pos. R1). 9. Turn the potentiometer (Fig. 5-18, Pos. P) of the service module further until the multimeter shows 9 VDC; the multimeter for the current reading should show a value corresponding to the value given in the circuit diagram, e.g. 550 mA (second step / 90% value [R2]). The LED’s show which channel (positiv A or negativ B) is activated. For adjustment use always potentiomenter in horizontal line to the activated LED’s. If necessary correct the value with potentiometer (Fig. 5-18, Pos. R2). 10. Repeat settings of item 8 and 9 until both mA values are stabilized, because R1 and R2 influence each other. 11. If the setting with either positive or negative potential was successful, turn the potentiometer (Fig. 5-18, Pos. P) of the service module into the opposite direction and check the settings with the other polarity. 12. Repeat the setting as described in steps 7 to 10. 13. Remove the multimeter, test leads, close* the terminals and reconnect the wire to terminal 5 of the amplifier module. *How to open and close the terminal: Push the yellow stud (Fig. 5-18, Pos. 1) down with a screw driver and turn it 90° to the left to open or to the right to close the terminal. Then a spring pushes the stud outwards and the contacts are either open or closed.

If the multimeter at the ramp time module does not show "0 V", adjust the value by turning potentiometer "Z" at the ramp time module. 2. Now set the output voltage of the service module to 10 V. Check the voltage reading of the multimeter connected to the ramp time module; if neccessary, adjust to "10 V" by turning the potentiometer "G". NOTE: Repeat settings of item 1 and 2 until both values are stabilized, because "Pot Z" and "Pot G" influence each other. Disconnect the test lead after the setting is done. NOTE: The factory setting of potentiometer "w1" to "w4" must not be adjusted!

Ramp time adjustment in relation to the operating movements: 3. Disconnect the cables at terminal 3 and terminal 5 of the respective module. Connect a multimeter for voltage reading to the ramp time module terminals marked "t" (+) and "⊥" (-). 4. For setting the ramp times "t1" to "t4" one after another: Apply +24 VDC to the corresponding terminal (9 to 12, see Fig. 5-20) of the ramp time module using a test lead. (+24 VDC can be taken from terminal 1 of the ramp time module itself.) Take the set value for the ramp time(s) from the corresponding table in the circuit diagram and set the voltage by adjusting the appropriate potentiometer marked "t1" to "t4" at the ramp time module. NOTE: The ramp time "t" corresponds to the voltage "Ut"set as desribed above, see following table and examples. Voltage Ut measured at socket "t" [V]

NOTE: Through the new release of the PM Clinic procedure (and adjustment of the Energy Efficiency), the ramp time modules (except swing and travel circuit) are basically adjusted to 20 ms / 5 V. For more details refer to your electric circuit diagram. The amplifiers and ramp time modules will soon be replaced with a closed control module for controlling.

In normal operation mode (floating position) the pilot pressure oil holds the spool in the single control blocks (via de-energized solenoid valves) open when lowering the boom or stick. If a pressurized lowering of the cylinders is required, the pilot pressure oil is switched via energized solenoid valves to the main control blocks. The solenoid valves (4/2-directional control valves) are controlled by push buttons located in the control levers (joysticks).

A secondary relief valve is installed to limit the maximum system pressure due to external forces.
Function Setting of the maximum permissible cylinder speed (flow B to A) is carried out by the adjustment pin (Fig. 6-6, Pos. 1). Depending on the setting, the radial holes (Fig. 6-6 Pos. 9.1) in the valve poppet (Fig. 6-6, Pos. 9) will be partially opened to achieve the required throttling of the oil flow. The extra holes (fixed throttle 9.2) prevent the valve from becoming completely closed. For the lifting operation (flow A to B), the valve poppet (Fig. 6-6 Pos. 9), which is guided by the pin (Fig. 6-6, Pos. 1), is pressed against the spring (Fig. 6-6, Pos. 7) so that the valve will be completely open. NOTE: Ex factory the throttle valves are pre-adjusted, refer to PM-Clinic.

NOTE: Remote control valves are part of the electric-hydraulic control system. Function The electric-hydraulic control system is used to control the direction and volume of oil flow to the operating cylinders and motors via the main control valve blocks. When a lever (or pedal) is actuated, a proportional solenoid valve (Fig. 6-8, Pos. 4) and one of the directional solenoid valves (Fig. 6-8, Pos. 5 / either Ax or Bx) are energized, allowing the pilot pressure oil to flow to the spools of the main control blocks. The proportional solenoid valve alters the pilot pressure, proportional to the lever deflection, resulting in a spool movement in the main control block between neutral and full stroke position.

NOTE: This solenoid operated directional spool valves are installed to control the start, stop and direction of an oil flow. Function In un-operated condition the control spool (Fig. 6-9, Pos. 1) is held in the neutral position by the reset springs (Fig. 6-9, Pos. 4). Operation of the control spool takes place by means of oil immersed solenoids (Fig. 6-9, Pos. 3). The force of the solenoid (Fig. 6-9, Pos. 3) acts via the plunger (Fig. 6-9, Pos. 2) on the control spool (Fig. 6-9, Pos. 1) and pushes it from its neutral position into the required end position. This results in the required flow from P to A and B to T, or from P to B and A to T. When the solenoid (Fig. 6-9, Pos. 3) is de-energised, the control spool (Fig. 6-9, Pos. 1) is returned to its original position by the reset springs (Fig. 6-9, Pos. 4).

NOTE: These valves are responsible for the creation of a variable control pressure proportional to the electrical signal output of an amplifier. Function In neutral condition the control piston (Fig. 6-10, Pos. 7) is held in the neutral or starting position by reset springs. The control piston (Fig. 6-10, Pos. 7) is directly operated by the proportional solenoid (Fig. 6-10, Pos. 3). If the solenoid is energised, it produces a force to operate the control piston (Fig. 6-10, Pos. 7) via the pressure spool (Fig. 6-10, Pos. 8) and moves the spool to the left. Oil flows from P to A. As pressure in A increases, it passes via the radial borings in the control piston (Fig. 6-10, Pos. 7) to the inner end of the pressure spool (Fig. 6-10, Pos. 4). The force generated by the pressure now works against the solenoid force and pushes the control piston (Fig. 6-10, Pos. 7) to the right (closing direction) until a balance is achieved between the two forces. In order to achieve this, the pressure spool (Fig. 6-10, Pos. 4) moves to the left in the direction of the piston stop (Fig. 6-10, Pos. 5). When the force balance is achieved, the connection between P and A is interrupted and the pressure in line A is held constant. Any reduction in the solenoid force leads to the pressure force exceeding the solenoid force on the control piston (Fig. 6-10, Pos. 7). The control spool is then moved to the right causing a connection from A to T, allowing the pressure to fall until a balance is re-established at a lower level. At rest, when the solenoid is de-energized, ports A and B are open to tank, while port P is blocked from both ports A and B.

Each spool is provided with "Fine Controlling Grooves", ring grooves for hydraulically centering of the spool and “Pilot oil warm up and flushing“ grooves. Pilot pressure between 8 and 19 bar moves the spools in their fine control range. The spool (Fig. 6-12, Pos. 3) is especially designed to keep the pressure channel connected to the center channel during the function “Boom lowering“ is selected, so that pump flow is available for other functions. The Load Holding Valves are installed beneath a plug from the service port side of the control block. The MRV is a pilot operated pressure relief valve.

Explanation of the schematic drawing of the control block: The hydraulic oil flows (Qmin = 190 liters/min) through the control block from port P to T, if all spools are in neutral position ("open center“). z
Fig. 6-13 ,Pos. A: E.g. the spools pilot pressure is built up in the control pipe line a1. (Imagine the upper symbol box moves to the center position.) Now pump oil flows through check valve (Fig. 6-13, Pos. 2) to the user port A1 because the free flow circulation to the hydraulic reservoir is closed. The main relief valve (Fig. 6-13, Pos. 1) limits the maximum operation pressure in this circuit. Via port B1 the return oil from the user is flowing back to the hydraulic reservoir. During down hill travelling motion and stopping procedure (e.g. travel motors) the anti cavitation valves (Fig. 6-13, Pos. 3) prevent cavitation on the hydraulic motors, because during these short periods of time the hydraulic motor needs a higher oil supply than the pump can deliver.
z
Fig. 6-13, Pos. B: E.g. spool #3 moves up when pilot pressure is built up in the control pipe b3. Now the user port B3 is supplied with pump pressure. Via port A3 the return oil from the user is flowing back to the hydraulic reservoir. The secondary relief valve (Fig. 6-13, Pos. 4) is additional installed in this circuit to protect the circuit against extreme pressure. The short-time extreme pressure also closes the check valve (Fig. 6-13 Pos. 2) which protects the hydraulic pump against extreme pressure peaks. The check valves (Fig. 6-13, Pos. 2) also have the function of load holding valves, because during the fine controlling period all lines are interconnected (negative over-lapping). For a moment, the load pressure is higher than the pump pressure.

Function Reset springs (Fig. 6-14, Pos. 2) move the spool (Fig. 6-14, Pos. 4) into neutral position. Fine control grooves (Fig. 6-14, Pos. 3) provide for sensitive controlling, because a motion is always started while the pressure oil and the return oil first pass these fine control grooves before the spool (Fig. 6-14, Pos. 4) is interconnecting the entire groove to the user channel. In neutral position of spool (Fig. 6-14, Pos. 4) the pump oil is flowing back via port PU to the tank. Lower Picture Example: The spool is moved to left position: Port PU is closed and the connection through the check valve RP1 to the user (port A) is open. In addition, the connection from the other user side (port B return) is connected to the port T (return line to tank). The return line of the pressure relief valve MRV (Fig. 6-14, Pos. 1) is also connected to the port T.

MRVs and SRVs are pilot operated relief valves. The MRV limits the max. pump supply line pressure. The SRV limits the max. possible pressure peak in the service-line. The valves have an „opening characteristic“. That means, that in case of contamination after the response procedure no further pressure increasing is possible and damages are avoided. z
Function: The circuit pressure P pushes the piston surface A of the main valve cone (Fig. 6-15, Pos. 15) with the force F1. Because there is the same pressure on the back side of the main cone via the jet bore (Fig. 6-15, Pos. 16), this, together with the spring (Fig. 6-15 Pos. 14) force, results in a force F2 that keeps the main cone closed. Via the jet bore (Fig. 6-15, Pos. 13) the circuit pressure is in front of the poppet (Fig. 6-15, Pos. 12). When the circuit pressure exceeds the setting value of the spring (Fig. 6-15, Pos. 11), the poppet opens against the force of the spring (Fig. 6-15, Pos. 11). As a result, force F2 decreases and there is no more balance condition between F1 and F2. The valve cone (Fig. 6-15, Pos. 15) is moved upwards by the greater force F1. That means now there is a direct connection from port P to T (tank).
ACVs serve for compensating a possible lack of oil when the SRV at the opposite port is actuated (see circuit diagram) and for avoiding cavitation damages. In addition, they serve to supply a user in case it is continuously moved by acceleration forces at zero position of the control spool. z
Function: The circuit pressure inside the spring chamber closes the valve cone (Fig. 6-15, Pos. 7). The back pressure of the return line acts on the surface of the valve cone (Fig. 6-15, Pos. 7). Whenever the pressure in the service-line is lower than the springs force, the valve cone opens by the force of the back pressure and hydraulic oil is additionally supplied.

Control blocks II and IV (4 spool blocks) The load holding valves are fitted into separate spaces of the control block housing, one valve for each spool. The load holding valves have three tasks: 1. When the circuit pressure is higher than pump pressure due to the attachment weight, these valves prevent dropping of the attachment, within their sensitive (fine controlling) range. 2. Due to sudden pressure peaks in the service-lines the valves also protect the pump. 3. When two pump flows are used for one user, the valves ensure that at least the flow of one pump reaches the user in case one MRV is defect or no longer properly adjusted. That means: Up to the max. pressure of the defective valve, both load holding valves are open allowing the flow of both pumps to the user. Then one valve will be closed by the higher pressure and the flow of one pump only flows to the user. Function The system pressure pushes onto the front area of the valve cone (Fig. 6-16 Pos. 1). This force moves the valve cone against the spring (Fig. 6-16 Pos. 2) and allows the oil to flow from the pump to the spool. In neutral position of the spool no further flow is possible (see circuit diagram). If the spool is no longer in neutral position, the flow continues to the user. If, due to an external force, the pressure directed to the pump overcomes the pump line pressure, this pressure forces the valve onto its seat (closed position).

NOTE: This is a principle drawing only, showing the location of load holding valves in valve block I and III. Control blocks I and III (3 Spool Blocks) The load holding valves are directly fitted into the spools (one on each side). The load holding valves have three tasks: When circuit pressure is higher than pump pressure due to attachment weight, these valves prevent dropping of the attachment, within their sensitive (fine controlling) range. Due to sudden pressure peaks in the service lines, the valves also protect the pump. When two pumps flows are used for one user, the load holding valves ensure that at least the flow of one pump reaches the user in case one MRV is defect or no longer properly adjusted. That means: Up to the max. pressure of the defective valve, both load holding valves are open allowing the flow of both pumps to the user. Then one valve will be closed by the higher pressure and the flow of one pump only flows to the user. Function In neutral position (upper picture) of the spool (Fig 6-17, Pos. 1) both valve cones (Fig. 6-17, Pos. 2) are closed by the springs (Fig. 6-17, Pos. 3). In a switched position (lower picture), the circuit pressure pushes onto the front area of the valve piston (Fig. 6-17, Pos. 2). This force moves the piston against the spring (Fig. 6-17, Pos. 3) and allows the oil to flow from the pump supply (Fig. 6-17, Pos. 4) to the user port (A) and from port B via boring (Fig. 6-17, Pos. 5) to the return oil passage. If, due to an external force, the pressure directed to the pump overcomes the pressure in the pump line, this pressure/force closes the valve (direction P to A).

Version 2010/1
COMPONENTS
Travel brake valve
Task Travel brake valves control the oil flow from the hydraulic motor to the tank depending on the operating pressure. This braking action prevents the motors from overspeeding.
Function Spring force keeps the spool in the lowest flow position. With increasing operating pressure the opening for the return oil flow becomes larger. On its way to the hydraulic motor the oil flows from A to A1 or B to B1, depending on the selected travel motion.
Example The operating pressure at port A moves spool (Fig. 6-18, Pos. 1) against the force of the spring (Fig. 6-18, Pos. 2) and opens the way for the return oil (Fig. 6-18, Pos. B1 to B). The check valve (Fig. 6-18, Pos. 3) prevents a direct oil flow from B1 to B. If the operating pressure decreases to such an extend that the spring force overcomes the pressure, the flow to the tank becomes restricted, resulting in braking of the machine.

NOTE: Pressure reducing valves are installed to reduce the common 45 bar pilot pressure to a lower pressure for other systems, e.g. the track tensioning system or the travel parking brake. Function Pressure reducing valves type DR & DP are direct operated valves of 3 way design, e.g. with a pressure relief function on the reduced pressure side. At rest, the valve is normally open, and oil can flow from port P to A. Pressure in port A is also present on the end of the spool (Fig. 6-19, Pos. 5) via control line (Fig. 6-19, Pos. 8), opposing the compression spring (Fig. 6-19, Pos. 3). When the pressure in port A reaches the pressure level set at spring (Fig. 6-19, Pos. 3), the spool (Fig. 6-19, Pos. 5) moves to the control position and holds the pressure in port A constant. Oil to control the valve is taken from port A via the control line (Fig. 6-19, Pos. 8). If the pressure in port A still rises further due to external forces, the spool (Fig. 6-19, Pos. 5) is moved further towards the compression spring (Fig. 6-19, Pos. 3). This causes a flow path to be opened over the cone (Fig. 6-19, Pos. 7) of the control spool (Fig. 6-19, Pos. 5) to tank. Sufficient fluid then flows to tank to prevent any further rise in pressure. An optional non-return valve (Fig. 6-19, Pos. 6) is available to allow free flow from A to P.

NOTE: These solenoid operated directional spool valves are installed to control the start, stop, and direction of an oil flow. Function When there is no flow through the valve, the control spool (Fig. 6-20, Pos. 2) is held in neutral or output position by means of the return springs (Fig. 6-20, Pos. 6). The control spool (Fig. 6-20, Pos. 2) is operated by means of oil immersed solenoid (Fig. 6-20, Pos. 4). The force of the solenoid (Fig. 6-20, Pos. 4) effects the control spool (Fig. 6-20, Pos. 2) by means of the plunger (Fig. 6-20, Pos. 3) and pushes it from its resting position to the required end position. This results in free flow from or P to B and A to T. When the solenoid (Fig. 6-20, Pos. 4) is de-energized, the control spool (Fig. 6-20, Pos. 2) is moved back to its resting position by means of return springs (Fig. 6-20, Pos. 6). An optional emergency operating device for manual operation (Fig. 6-20, Pos. 5) allows movement of the control spool (Fig. 6-20, Pos. 2) without energizing the solenoid.

NOTE: The pressure double stage valve is a remote controlled pressure relief valve, actuated by hydraulic pressure. The individual relieve pressure is determined by the pilot pressure. Function The valve poppet (Fig. 6-21, Pos. 2) is connected via the jet bores (Fig. 6-21, Pos. 11 and Pos. 12) with port P. If static pressure increases above the set pressure value, the valve poppet (Fig. 6-21 Pos. 2) opens and allows oil to flow freely to tank (T1). This oil generates a pressure drop in the spring chamber of the main spool, the closing force of the spring (Fig. 6-21, Pos. 6) is cancelled, and the main piston (Fig. 6-21, Pos. 5) opens to allow the pump flow to tank (T2). Damped opening and closing is obtained by the throttled volumetric change. By applying external pressure of Pst max = 45 bar to the main spool (Fig. 6-21, Pos. 9) via port X, the pre-tensioning of the pressure spring (Fig. 6-21, Pos. 3) is increased by the amount of the piston stroke "S", and system pressure is increased correspondingly. The possible pressure increase p is 440 bar max. or 440 bar minus the basic setting. The setting is fixed by means of the setting screw (Fig. 6-21, Pos. 7) and lock nut (Fig. 6-21, Pos. 13); 1 turn of the screw = 150 bar.

Hydraulic cylinder
COMPONENTS
Function Hydraulic cylinders (also called linear hydraulic motors) are actuators which convert fluid power into mechnical power. The cylinders get their power from pressurized hydraulic fluid, typically oil. Hydraulic cylinders are used at high pressures to produce large forces and presice movements. Therefore they are constructed of strong materials and designed to withstand large forces. The hydraulic cylinder is the the actuator or "motor" side of the system. The "generator"side of the system is the hydraulic pump which brings in a regulated flow of oil to the bottom side of the cylinder to move the piston rod outwards. The oil in the chamber on the rod side is pushed back to the oil tank. The force of the cylinder depends on the hydraulic oil pressure and the piston face. The force F is given by the formula F = p A, where p is the pressure (in N/m²) and A is the face (in m²) of the piston the pressure acts on. That means, that the force of the hydraulic oil can be multiplied as needed, the maxium force is only limited by the dimension of the piston face. Structure The layout of the hydraulic cylinder is shown in Fig. 6-22. The piston (Fig. 6-22, Pos. 10) separates the two sides of the cylinder barrel internally. To prevent leakage from one side to the other, the piston is fitted with the piston seal (Fig. 6-22, Pos. 6) and the rod seal (Fig. 6-22, Pos. 16). At the other side of the cylinder, there are 4 different seal packages: – a dust seal (Fig. 6-22, Pos. 29) the prevent dirt beeing drawn into the cylinder – a rod packing (Fig. 6-22, Pos. 26) as the main seal to the outside – a buffer ring (Fig. 6-22, Pos. 23) to prevent leakage between the cylinder head and the piston rod – a cylinder head seal (Fig. 6-22, Pos. 20) to prevent the leakage from the fit between cylinder head and barrel. The cylinder head (Fig. 6-22, Pos. 10) is bolted to the cylinder barrel (Fig. 6-22, Pos. 7).
WARNING During commissioning and when new hydraulic cylinders are installed, first of all, the air has to be bled from the cylinders, refer to the ’air bleeding’ procedure described in the TROUBLESHOOTING MANUAL.
NOTE: In case abnormal movements of the hydraulic cylinder are noticed, carry out a cylinder bypass test, refer to the TROUBLESHOOTING MANUAL.

Example C with the following conditions: z
Engine running (high idle)
z
Pump circuit pressure less than X4 = 60 bar (pump support pressure).
z
X1 = 34 bar (pump regulation pressure), this pressure will not influence the Qmin position under these conditions.
z
X3 = 0 bar (remote control pressure); 57K517 de-energized (Qmin activated) for pumps #2, #3 and #4. For pump #1, 57K517 de-energized and 57K626 energized.
z
X4 = 60 bar (pump support pressure). Pump support pressure is present at valve #7, the slipper pad of piston #14 and the small area side of the positioning piston #13.
Response of pump control mechanism: Valve #7 moves to position "b" because the X4 pressure exceeds the spring force, since the oil behind nozzle (Fig. 7-11, Pos. 8) flows through valve #6 (which is in position "a", due to the missing remote control pressure X3) back to tank. Pump support pressure X4 passes valve #7 position "b" and flows via power control valve #9 position "a" to the large area side of positioning piston #13 Because the large area side of positioning piston #13 is approximately three times larger than the small area side, the pump support pressure X4 of 60 bar present on both sides, resulting in stronger force at the large area side, keeps the pump in Qmin position. NOTE: The pump remains in Qmin position.

z
X4 = 60 bar (pump support pressure), present at valve #7.
Response of pump control mechanism: Valve #7 moves to position "a" because the spring force is supported by the X4 pressure, since the oil flow back to tank is blocked at valve #6 (which is in position "b", due to the 45 bar remote control pressure X3). The large area side of positioning piston #13 is connected, via power control valve (Fig. 7-12, Pos. 9) position "a" and pressure balance valve (Fig. 7-12, Pos. 7) position "a", to the return oil line.

z
X4 = 60 bar (pump support pressure), present at valve #7.
Response of pump control mechanism: Valve #7 moves to an intermediate position (in-between "a" and "b"), since a certain amount of oil behind nozzle (Fig. 7-13, Pos. 8) flows through valve #6 (which is also in an intermediate position, due to the 15 bar remote control pressure X3) back to tank. The large area side of positioning piston #13 is connected, via power control valve (Fig. 7-13, Pos. 9) position "a" and pressure balance valve (Fig. 7-13, Pos. 7), to the return oil line. The pump moves into ½Qmax position, because the return oil flow through pressure balance valve (Fig. 7-13, Pos. 7) is restricted (due to its intermediate position), resulting in a pressure at the large area side of the positioning piston (Fig. 7-13, Pos. 13).

z
X4 = 60 bar (pump support pressure), present at valve #7.
Response of pump control mechanism: Valve #7 moves to position "a" because the spring force is supported by the X4-pressure, since the oil flow back to tank is blocked at valve #6 (which is in position "b", due to the 45 bar remote control pressure X3). The operating pressure (with the value for start of de-stroking) at the slipper pad of piston #14 moves the power control valve (Fig. 7-14, Pos. 9) into position "b" (against the spring force supported by the X1-pressure). This in turn connects the operating pressure to the large area side of positioning piston #13. Because the large area side of positioning piston #13 is approximately three times larger than the small area side, the operating pressure present on both sides, resulting in stronger force at the large area side, moving the pump in Qmin direction. NOTE: The pump de-strokes until the forces at positioning piston #13 are balanced.

Response of pump control mechanism: Independent of the position of power control valve #9, the pressure cut-off valve #11 causes the pump to de-stroke to the pre-adjusted Qmin position. The operating pressure moves the pressure cut-off valve #11 (at set pressure) into position "b" and flows to the large area side of positioning piston #13. Because the large area side of positioning piston #13 is approximately three times larger than the small area side, the operating pressure present on both sides, resulting in stronger force at the large area side, moving the pump in Qmin position.

ELECTRONIC LOAD LIMITING CONTROL - GENERAL
The drive train of the excavator consists of a Diesel engine, several hydraulic pumps, which supply cylinders and hydraulic motors. The load limiting control ensures optimum use of the power required for the excavator under varying operating conditions and avoiding overload of the Diesel engine. Fig. 7-20 shows the principle of the electronic load limiting control. The RC4-4 (10K032) processes the following input signals: z
Diesel engine speed (Pin 33) from magnetic pick-up (52B064).
z
Switch signal (Pin 37) from engine control (25K014-1), 24 V if n > 300 rpm.
The RC4-4 (10K032) processes the following output signals: z
Signal value to control the proportional solenoid valve 57K561-1 (Pin 31).
z
Switch signals (Pin 15 and 29), diagnostic of the RC4-4 (10K032).
The Diesel engine drives four variable displacement pumps by means of a PTO-gearbox. Each pump is equipped with a hydraulic power controller (HPC). This controller limits the input torque of the pump to an adjusted command value (X1-pressure, for start of destroking). The command value (X1-pressure) is present via proportional solenoid valve 57K561-1 at the hydraulic power controllers of each pump. The actual speed of the engine is measured with a speed sensor at the flywheel. NOTE: The auxiliary hydraulic pumps and other consumers can be operated without being directly affected by the load limiting control. The control algorithm of the load limiting control always compares the actual engine speed with the rated load speed. With increasing load the engine torque will rise and the engine speed will drop. For this reason the electronic load limiting control will be initiated when the load speed falls below 1800 rpm, i.e. the torque of the main pumps will be lowered (by reducing the X1-pressure) until the rated speed of 1800 rpm is attained again.

MICROCONTROLLER RC4-4
The RC4-4 microcontroller is used for the programmable control of a maximum of four proportional solenoids and four additional switching functions. As input signals, the microprocessor processes analog voltages in the 0 V to 5 V range and switching information. All inputs are protected against overvoltage and electrical interference. As output signals, the output stages of the RC4-4 deliver closed loop controlled currents for the connection of proportional solenoids. The analog voltage output is suitable for the simple forwarding of analog information to other electronic circuits. Characteristics z
Closed loop control of solenoid currents, i.e. independent of voltage and temperature.
z
Pulse width modulated (PWM) solenoid currents for minimal hysteresis.
z
Internal buzzer for programmable monitoring of functions or errors.
Setting and Display Facilities All calibration operations and the display of functions, faults and system variables are connected via the serial interface to a PC w ith the BODEM 24 software.

Microcontroller RC4-4 (Fig. 7-25) Method "A" X1-pressure adjustment with 24 V supply to separating terminals at the X2-switch over the 11X_09 board. Pre-conditions: Normal operating temperature, correct pilot pressure setting and the system must be free of air. 1. Make sure the change-over valve is in position “Electronic Pump Regulation”. 2. Connect a pressure gauge to test port (M18), using a long pressure gauge hose to be able reading the pressure in front of the 11X_09 board. 3. Selection of adjusting mode: Turn the main key switch in on position and activate the adjusting mode as follows: Connect 24 V, simultaneously to terminals 11X_09-4 and -5 for 10 seconds, using two test leads and disconnect the voltage thereafter. 4. Selection of the required proportional solenoid valve: With the main key switch still in ON position, the output terminal of proportional solenoid valve 57K561-1 is directly selected. Since there is only one engine with one proportional solenoid valve installed, a 24 V connection is not required. 5. Adjusting the X1-pressure: Start the engine, let it run with maximum speed. Read the pressure, required = 34±0,5 bar. If necessary, increase the X1-pressure as follows: Connect 24 V to terminal 4. NOTE: As long as voltage is supplied, the X1-pressure drops to zero. After interrupting the voltage supply, the gauge pointer will move slowly to the new X1-pressure. NOTE: Example: Keeping voltage supply for two seconds will increase the X1-pressure of approximately 1 bar. 6. To decrease the X1-pressure connect 24 V to terminal 5 and proceed as described under item 5; keeping voltage supply for two seconds will decrease the X1-pressure of approximately 1 bar. 7. After the adjustment is finished, remove the test leads and the pressure gauge, and turn the main key switch in OFF position to deactivate the adjusting mode.

The pilot pressure oil X2 (45 bar) maintained at pressure relief valve (Fig. 7-31, Pos. 252.1) flows through the manifold to the pressure relief valve (Fig. 7-31, Pos. 253.2), which reduces the X2 pressure to the necessary constant X1 pressure to prevent the engine from overloading. NOTE: For testing purposes, the pump regulation system can be changed to the hydraulic operation mode.

7.6.1
GENERAL
The engine speed sensor 52B064-1 (pick-up), together with the RPM-module 51T018-1, use the flywheel teeth to count RPM. With running engine, each tooth induces a coltage in the pick-up coil. That causes an alternative voltage at the pick-up coil wire. With engine at stand still, there is no voltage at the pick-up wire. The frequency of this alternative voltage will increase or decrease proportional to the engine RPM. The RPM-module converts the frequency into a proportional milliampere signal. This signal is used for different components, e.g. pump regulation, display, VHMS.
7.6.2
ENGINE SPEED SENSOR (PICK-UP) ADJUSTMENT
1. Stop the engine. 2. Disconnect plug at the pick-up wire. 3. Loosen the look nut. 4. Turn out the pick-up completely ccw. 5. Check front end of the pick-up and clean it from magnetic chips and dirt. 6. Turn the pick-up completely in (cw) until it touches the flywheel (Fig. 7-34, Pos. A). 7. Turn the pick-up ¾ turn out (ccw) (Fig. 7-34, Pos. B). 8. Secure the pick-up with look nut (Fig. 7-34, Pos. C). 9. Connect the plug. Final Check 10. Start engine and let it run at high idle. 11. Check the voltage (AC) of the pick-up. Insert the T-box on the sensor connector and connect between pick-up and RPM-module 51T018-1. 12. The voltage should be 10±2.5 volts AC.
WARNING z
Avoid pick-up contact with the flywheel while engine is running!
z
The induced AC voltage must be measured with connected pick-up to the RPM-module.

GENERAL
Energy which is not used for active movements can be considered as a loss of energy. Although energy can not be destroyed, it can be converted into heat, which is useless for performing work by means of hydraulics. With the following measures the energy efficiency in your machines is optimized, the oil delivery takes place through specified pumps corresponding to the definite movements of the excavator. NOTE: If individual movements (single movements) are selected, the pumps will have maximum flow, but with one exception. Pump No. 1 will have half flow when high speed swinging is selected (important for PMclinic and other tests). z
Individual movements of the attachment are selected: => 57K646 OFF + 57K647 OFF + 57K648 OFF + 57K626 ON

To check the function of the Energy Efficiency System it is necessary to follow the instructions below. Adjusting the flow control: 1. Connect a pressure gauge (0-60 bar) to test port M19. 2. Turn the superstructure 90° to the travel direction. 3. Apply the slew parking brake. 4. Move the bucket close to the side frame and raise one track off the ground just enough to get the track free. 5. Activate the travel pedal of the lifted track fully in one direction. Make sure there is no other function activted. 6. Test of max. pump flow: 57K646, 57K647 and 57K648 must be de-energized, and 57K626 must be energized. Check the time of five (5) sprocket revolutions, see table Fig. 7-38. 7. Test of optimized pump flow: Activate the swing function (against the brake). 8. Let the sprocket turn with the swing function still applied (slew parking brake closed). 9. Measure the time for five (5) sprocket revolutions; see table Fig. 7-38 for the required value.
CAUTION Values are based for machine working from see level up to 3600 m. Machines working on higher altitude require a reduced Qmax setup which influences the test values.
NOTE: X3 or PST: both are the same pressure. It is the pressure to control the maximum permissible pump output flow. PST is the port name of the main pump.

General Information The control blocks, the piping to the distributor manifold and the connecting hoses to the attachment are different between the backhoe attachment (BHA) and the front shovel attachment (FSA). If a conversion is required, contact the service department for further information. Function: NOTE: Also refer to the circuit diagram. NOTE: The following numbering refers to the hydraulic circuit diagram. Each main pump (Fig. 8-1, Pos. 1 to 4) delivers oil trough the high pressure filter (13.1 to 13.4) to port P of the main control blocks (I to IV). This results in four main circuits. If all spools of the control blocks (I to IV) are in neutral position, the oil flows through the blocks at port T and returns via return oil pipes, return oil collector manifold (107), return oil pipes (L6 and L7), return oil collector pipe (54), back pressure valve (55) and the return oil filters (49.1 - 49.4) into the tank. The function of back pressure valve (55) ensures: z
sufficient oil supply for all anticavitation valves
z
and that sufficient oil is forced through the oil coolers.
If a control lever or pedal is actuated, pilot pressure oil moves the spools of the control blocks, directing the oil flow from the main pumps to one side of the user (either cylinders or motors). From the opposite side of the user, the oil returns to the control block, and from there flows via the return oil circuit back into the tank. Each circuit is provided with one MRV (Main Relief Valve), at least one SRV (Secondary Relief Valve) and at least one flow restrictor.

FLOATING SYSTEM

Floating function of boom and stick cylinders, FSA

Version 2010/1
OPERATING HYDRAULICS
General
The excavator operates automatically with the floating position for boom and stick activated. That means the lowering movement of boom and stick is always done in the floating position. For deactivation of the floating position, two push-buttons are installed: z
20S095 in the right joystick (20S019) for the boom function,
z
20S098 in the left joystick (20S020) for the stick function.
Press the respective button and keep it depressed as long as the floating position shall be deactivated. When releasing the button, the floating position is activated again. Function: The additionally installed single control blocks (Fig. 8-2, Pos. 60Q632, 60Q633, 60Q634 and 61Q635) connect the piston side of the cylinders with the rod side and also with the tank: z
60Q632, 60Q633 and 60Q634 for the stick cylinders,
z
61Q635 for the boom cylinders.
In normal operation mode (i.e. floating position) the pilot pressure oil is directed via 60Q632, 60Q633 and 61Q635 to the single control blocks when lowering the boom or stick. If a pressurised lowering of the cylinders is required, the pilot pressure oil is directed via 60Q632, 60Q633 and 61Q635 to the main control blocks. The solenoid valves 60Q632, 60Q633 and 61Q635 (4/2-directional control valves) are controlled by push-buttons 20S095 and 20S098. Boom:
20S095 ON => 61K635 ON => Floating position deactivated 20S095 OFF => 61K635 OFF => Floating position activated
Stick:
20S098 ON => 61K632 + 61K633 OFF => Floating position deactivated 20S098 OFF => 61K632 + 61K633 OFF => Floating position activated
NOTE: Due to the two different operation modes for lowering, the lowering speed of boom and stick cylinder must be adjusted twice: • floating position deactivated, • floating position activated.

Each pump circuit can be checked or adjusted individually by selecting one function of the required pump circuit. Checking: 1. Connect the gauge to the required test port M11 - M14. 2. Start engine and let it run at high idle. 3. Extend or retract the cylinder to the stop position for the valve being tested until the hydraulic system stalls. 4. Read the pressure. Required: 310+5 bar. If the pressure is not correct, carry out a comparative measurement with another function, in order to avoid wrong measuring results caused by wrongly adjusted SRV or other defects in the system. Adjusting: 1. Remove protective cap (Fig. 8-17, Pos. a). 2. Loosen lock nut (Fig. 8-17, Pos. b). 3. Turn set-screw (Fig. 8-17, Pos. c) clockwise to increase pressure, or counter-clockwise to decrease pressure. 4. Tighten lock nut (Fig. 8-17, Pos. b) and install cap (Fig. 8-17, Pos. a).
NOTE: It is important that the valve bodies of the MRVs and the SRVs are firmly tightened (with 300 Nm). Otherwise, the internal sealing is not properly, which results in loud flow noises and wrong adjustments.

1. Connect gauges to all above listed test ports. 2. Start engine and let it run at high idle. 3. Extend the boom cylinder to the stop position until the hydraulic system stalls. 4. Slowly increase the pump circuit pressure by turning in set-screws (Fig. 8-19, Pos. 3) of both MRVs in control block II and IV while observing the pressure gauges. Stop as soon as the pressure does not rise any further. The gauge pointers should remain at 350±5 bar. NOTE: Since the piston side of the boom cylinders are protected by several SRVs, the pressure gauges show the pressure of the valve with the lowest setting.

CHECKS AND ADJUSTMENTS OF THE LOWERING SPEED
General On excavators equipped with face shovel attachment (FSA), there are two different operation modes for lowering the boom and stick: 1. Floating position activated, the lowering speed is restricted by the stroke limiters (Fig. 8-41, Pos. 1) of the single control blocks (Fig. 8-41, Pos. 2). (Standard adjustment: ’fully open’) 2. Floating position deactivated, the lowering speed has to be adjusted at the the flow restrictors (throttle valves) at the distributor manifold (Fig. 8-41, Pos. 42). On excavators equipped with backhoe attachment (BHA), the lowering speed has to be adjusted at the flow restrictors only (no floating system installed). Purpose of the flow restrictors: z
To avoid an interruption (stops during movements) of the pump delivery.
z
To provide smooth cylinder movement.
z
To limit the return oil flow through the control block to the maximum permissible volume.
Checks and adjustments: z
Standard test method is measuring the total cylinder running time (from start to final stop) by using a stop watch.
z
Basic adjustment of all restrictors as follows: z
For easy turning of set-screw (Fig. 8-41, Pos. 3), lower the attachment to ground, stop motor and allow pressure equalising by moving the joysticks several times.
z
Loosen the lock nut (Fig. 8-41, Pos. 4) and turn the bolt (Fig. 8-41, Pos. 3) cw. for more restriction and ccw. for less restricton. If more than one restrictor is used for one movement make sure all set-screws are equally adjusted.
NOTE: For the values to be set, refer to column "Nominal" in the PM-CLINIC data sheet for the respective attachment (FSA / BHA), see following illustrations (extracts – sample only). FSA:

Boom cylinder FSA Due to the 2 different operation modes for lowering the boom, the lowering speed must be adjusted twice: 1. Floating position activated 2. Floating position deactivated Maximum permissible lowering speed Refer to the PM-CLINIC sheet for your machine. Adjustments / checks (floating position activated): 1. Use a stop watch to measure the time for the cylinder movement (from start to final stop). NOTE: Pay attention to measure the time of the cylinder movement only. 2. Raise the fully extended attachment with empty bucket to the maximum height position (Fig. 8-42, Pos. A). 3. Run the engine at high idle. 4. Lower the attachment; do not press button 20S095 (floating position switch). Rapidly move the control lever 20S019 to the front end position (start stop watch when the boom starts moving) and hold the control lever in this position until the final position (Fig. 8-42, Pos. B) is reached (stop the stop watch). NOTE: Lower the boom so that the bucket stops just above the ground. 5. If the lowering speed is too high (measured time is less than the permissible time), the speed must be reduced by adjusting the stroke limiter of the single control block (Fig. 8-42, Pos. 61Q635). Adjust as follows: z
To decrease the lowering speed, loosen the lock nut (Fig. 8-42, Pos. 2) and turn the bolt (Fig. 8-42, Pos. 1) clockwise.

Brief description (service circuits) The machine is equipped with a two speed swing system (also refer to the hydraulic and electric circuit diagram). The swing motors (Fig. 8-51, Pos. 60.1 + 60.2) are driven by the pumps (Fig. 8-51, Pos. 1 + 3). The oil flows from the pumps through high pressure filters to the control block (Fig. 8-51, Pos. 9/III) and (Fig. 8-51, Pos. 10/I). With the spools in neutral position, oil flows via the return oil line into the collector pipe (107) and further via the return oil lines (L6 + L7) back to the tank. On the way back to the tank the oil must flow through the back pressure valve (55) and the return oil filters (59.1 59.4). (For the back pressure valve function, refer to section 4.2 on page 4-4). When operating the control lever for "swinging", the pump line is connected in the control blocks (Fig. 8-51, Pos. 9/III and 10/I) with the corresponding service line (A1 or B1) to the swing motors (Fig. 8-51, Pos. 60.1 + 60.2). The oil flows from the control block through each of the swing brake valves (61.1 + 61.2; for description refer to section 8.3.7 on page 8-116) and the swing motors (Fig. 8-51, Pos. 60.1 + 60.2). Each swing gear includes one spring loaded multi-disk brake for locking the superstructure. The leak oil (case drain) flows through the lines (L18 + L19) and the leak oil filter (53) back to the tank.

If swing speed switch 20S154 is activated, also proportional solenoid valve 61K566 and, depending on the swinging direction, directional solenoid valves 61K526 (swing right) or 61K527 (swing left) are energized. Simultaneously solenoid valves 57K630 and 57K626 (pump #1 fixed in ½ Qmax position) are energized, so that only a reduced oil flow from pump #1 will be added to increase the swing speed. I.e.: Swing speed fast = oil flow of pump #3 + reduced oil flow of pump #1
Description When the lever (Fig. 8-53, Pos. 20S020) is moved out of its neutral position, proportional solenoid valve 61K565 and solenoid valve 57K631 (pump #3 fixed in Qmax position) are energized. Simultaneously the directional solenoid valves 61K524 (swing right) or 61K525 (swing left) are energized. At the same time, by the function of proportional solenoid valve 57Q627, pilot pressure is present at port "X" of each brake valve block.

Axial piston motor A2FLM The axial piston units of product group A2FM with fixed displacement can operate as a hydraulic motor only. The drive speed is proportional to the consumption capacity. The output torque increases with the pressure drop between high and low pressure side. The motor converts hydrostatic energy into mechanical energy.
Version 2010/1
The main part of the axial forces is supported by the slipper pads (Fig. 8-54, Pos. 13) which are installed on the driving circular side of the drive shaft. Each piston is allocated to one slipper pad. These slipper pads are located in the cylinder chamber and get pressurized via piston borings (Fig. 8-54, Pos. 5).
"Clockwise" = Direction of flow A to B "Counter-clockwise" = Direction of flow B to A with view onto drive shaft! Via the control lens (Fig. 8-54, Pos. 8), the oil is directed to the cylinder bores. The piston (Fig. 8-54, Pos. 5) is moved from the lower (Fig. 8-54, Pos. 6b) to the upper dead point (Fig. 8-54, Pos. 6a) by means of the force acting on it and causes the drive shaft to rotate. On further rotation of the drive shaft (additional pistons are pressurized), this piston is moved towards the lower dead point again, and oil of the cylinder chamber is forced out through the kidney formed openings of the control lens. This oil is fed back to the tank via the return line. If the supply and return line is changed, it changes the output drive direction of the drive shaft. By means of the angled arrangement of the cylinder (Fig. 8-54, Pos. 7) (bent axis design), a certain piston stroke is produced which results in a fixed displacement per revolution of the drive shaft. According to the size of the applied flow, this produces a specific output speed.The output torque at the drive shaft is dependent on the size of the motor and the required operating pressure.

The sun shaft of the first planetary stage (Fig. 8-55, Pos. 17) transmits the torque into the second planetary stage (Fig. 8-55, Pos. 19). By the planetary gears, the output drive shaft is rotated and transmits the torque to the pinion (Fig. 8-55, Pos. 21). The drive housing and the gearbox are filled with gear oil.

The swing gear is of compact design with a two stage planetary gear including a multi-disk brake. The gear is bolted to the superstructure and fits firmly due to the machined diameter (Fig. 8-56, Pos. A) and the bolt torque. The torque loaded on the hydraulic motor is transmitted by drive shaft (Fig. 8-56, Pos. 2) and sun gear shaft (Fig. 8-56, Pos. 3) to the first planetary stage (Fig. 8-56, Pos. 9).

By the planetary gears of the second stage, the output drive shaft is rotated and transmits the torque to the pinion (Fig. 8-56, Pos. 17). Drive housing, gearbox and brake housing are filled with oil. Aeration is done by breather filters. NOTE: In opposition to the parking brake installed to the L&S swing gear, the SIEBENHAAR slew parking brake is not splash lubricated through gearbox oil.

The spring loaded multi-disk brake is a safety brake; applied by spring force and released by oil pressure. The slew parking brake is a "wet brake", because the brake housing is splash lubricated by the gearbox oil. Function Brake applied: The outer disks (Fig. 8-57, Pos. 4) engaged to the housing by serration and the inner disks (Fig. 8-57, Pos. 3) in serrated connection with drive shaft (Fig. 8-57, Pos. 12) are pressed together by the springs (Fig. 8-57, Pos. 9). This results in a fixed connection between housing and drive shaft. Brake released: Oil pressure via port (Fig. 8-57, Pos. 13) reaches the bottom of the piston (Fig. 8-57, Pos. 6) and forces the piston upwards against the thrust washer (Fig. 8-57, Pos. 10). This function eliminates the spring force onto the disks so that the sinus (spacing) rings can keep the outer disks (Fig. 8-57, Pos. 4) apart, thus the brake is released. The releasing pressure is 19-20 bar, the maximum permissible pressure 60 bar.

This results in a fixed connection between housing (Fig. 8-58, Pos. 11) and drive shaft. Brake released: Pressure oil runs through port (Fig. 8-58, Pos. 4) to the chamber between the piston (Fig. 8-58, Pos. 5) and the brake housing ring. The oil moves the piston upwards away from the brake disks (Fig. 8-58, Pos. 1 and 2) when the resulting force exceeds the force of the springs (Fig. 8-58, Pos. 6). When the piston is lifted, the spring force onto the disks is eliminated. The required releasing pressure is 19-20 bar, the maximum permissible pressure 60 bar.
The spring loaded multi-disk brake is a safety brake; applied by spring force and released by oil pressure. The slew parking brake is a "wet brake", because the brake disks are lubricated by the oil filling in the brake housing.

The oil for the hydraulic motor from the control block arrives at the service line port A or B, depending if a R.H. or a L.H. swing motion is carried out with max. MRV pressure.
Whenever the pressure is higher than the setting of the pressure increasing valve, this valve opens and dumps the oil into the return line (Fig. 8-59, Pos. T) to tank. The pressure can be checked at the test ports MA or MB. If after a swing motion the joystick is put into neutral position without using the foot brake, the superstructure is turned by inertial force and the hydraulic motor acts as a pump because it is driven by the swing gear. In this period the pressure in the service line is lower than the pressure in the return line, because there is a back pressure valve at the tank line, and oil is forced through the anti-cavitation valves into the service line.
By applying pilot pressure via the external port X to piston (Fig. 8-59, Pos. 6), the pre-tensioning of the pressure spring (Fig. 8-59, Pos. 8) is increased by the amount of the piston stroke "S", which results in the actual valve setting. The system pressure is in front of the main piston (Fig. 8-59, Pos. 13) and via the jet bore (Fig. 8-59, Pos. 12) also in the chamber of the spring (Fig. 8-59, Pos. 11) and via the jet bore (Fig. 8-59, Pos. 10) at the pressure relief valve poppet (Fig. 8-59, Pos. 9). Due to the force balance, the piston (Fig. 8-59, Pos. 13) is kept in its position supported by the spring (Fig. 8-59, Pos. 11). Does the system pressure exceed the setting of the valve (Fig. 8-59, Pos. 9), this valve opens a channel to the dump line port (Fig. 8-59, Pos. Y). Due to the drop of force, the piston (Fig. 8-59, Pos. 13) is moved to the right. The pressure line gets connected with the return line (Fig. 8-59, Pos. T). The shuttle valves 270.1 and 270.2 stabilize the pilot pressure for the double stage valve (lower stage) to avoid pressure sequences when starting swinging.
The ports A and B are internally connected to the ports A’ and B’, and these ports in turn with the hydraulic motor. The operating pressure, either at port A or B closes the anti-cavitation valves Version 2010/1

NOTE: It is important that the complete MRV and the double stage valve is firmly tightened (with 300 Nm). Otherwise, internal leaks could occur which result in: problems of incorrect adjustment, loud flow noises, abnormal swing movements and high temperatures. NOTE: Whenever pressure checks are carried out, they must be carried out for both, R.H. and L.H. swinging to make sure the shuttle valves in the control lines and the check valves in the brake valve blocks are in good condition. NOTE: Because the swing motors are working hydraulically in combined operation, the pressure gauge shows the pressure of the double stage valve with the lowest setting. Even if the gauge shows the required pressure, it is possible that one valve has a higher setting. Therefore, lower the pressure on one valve below the required pressure, and then increase up to required pressure. Proceed with next valve in the same manner. High pressure check / adjustment 1. Connect gauges to test ports M11 and M14 at the high pressure filters. 2. Disconnect the pilot pressure lines from the double stage valve and close the lines with a suitable plug (Fig 8-64, Pos. 6). 3. Loosen lock nut (Fig. 8-64, Pos. 3) of both double stage valves (DSV) and screw in set-screw (Fig. 8-64, Pos. 4) until piston (Fig. 8-64, Pos. 5) comes to stop. 4. Start the engine and let it run at high idle. 5. Lower attachment to ground and apply the slew parking brake with switch 20S029. 6. Adjust the MRVs to ~350 bar. 7. Actuate either L.H. or R.H. rotation (20S154 ON) until the hydraulic system stalls. Read the pressure, required = 330±5 bar. 8. If the gauge shows a lower or higher value, the valves must be adjusted: z
Loosen lock nut (Fig. 8-64, Pos. 1) of the second stage (330 bar) of the DSV.

Description (Also use the hydraulic and electric circuit diagram.) The travel motors (Fig. 8-71, Po. 21.1 and 21.2) are driven by the pumps (Fig. 8-71, Pos. 2 and 4). The oil flows from the pumps through the high pressure filters to the control blocks (Fig. 8-71, Pos. II and IV). In neutral position of the spools the oil flows via the return oil lines into the return manifold (107) and further via the return oil lines (L6 and L7) into the collector pipe (54), and further through the filter back to the tank. On its way to the tank the oil must flow through the back pressure valve (Fig. 8-71, Pos. 55) and the return oil filter (59.1 - 59.4). (For back pressure valve function refer to section 4.2 on page 4-4.) When operating the foot pedal for "Travelling" the pump line of each control block is connected with the corresponding service line (A1 or B1) via the rotary distributor (Fig. 8-71, Pos. 19) and travel brake valves (Fig. 8-71, Pos. 56.1 and 56.2) to the travel motors (Fig. 8-71, Pos. 21.1 and 21.2). The travel brake valve acts as a flow control valve in order to avoid the travel motors picking up speed when travelling downhill. Each travel gear includes a spring loaded multi-disk brake (house brakes 57.1 and 57.2). They are used as parking brakes, automatically applied by the function of 57Q516 whenever the engine is switched OFF, or the ladder or the refilling arm is in bottom position. The leak oil (case drain) flows through the line (Fig. 8-71, Pos. L9) and the leak oil filter (53) back to the tank.

Direction of rotation:
with view onto drive shaft! Via the control lens (Fig. 8-72, Pos. 8), the oil is directed to the cylinder bores. The piston (Fig. 8-72, Pos. 5) is moved from the lower (Fig. 8-72, Pos. 6b) to the upper point (Fig. 8-72, Pos. 6a) by means of the force acting on it and causes the drive shaft to rotate. On further rotation of the drive shaft (additional pistons are pressurized), this piston is moved towards the lower point again and oil of the cylinder chamber is forced out through the kidney formed openings of the control lens. This oil is fed back to the tank via the return line. If the supply and return line are interchanged, the output drive direction of the drive shaft is changed. By means of the angled arrangement of the cylinder (Fig. 8-72, Pos. 7) (bent axis design), a certain piston stroke is produced which results in a fixed displacement per revolution of the drive shaft.
Axial Piston Motor A2FLM The axial piston units of product group A2FM with fixed displacement can operate as a hydraulic motor only. The drive speed is proportional to the consumption capacity.
According to the size of the applied flow, this produces a specific output speed. The output torque at the drive shaft is dependent on the size of the motor and the required operating pressure.
The output torque increases with the pressure drop between high and low pressure side. The motor converts hydrostatic energy into mechanical energy.

Hydraulics for the travel circuit
Function During operation superstructure and under carriage constantly rotate towards each other. Nevertheless, the travel oil motors must be supplied with hydraulic oil in every position in which the superstructure is moved in regard to the undercarriage. Oil is directed by the control blocks to the ports (Fig. 8-73, Pos. A - D) of the housing (Fig. 8-73, Pos. 2). The oil flows to the outlet ports (Fig. 8-73, Pos. A - D), of the rotor (Fig. 8-73, Pos. 1), via ring grooves as well as longitudinal and cross holes. The rotor is bolted to the under carriage. The sealing of the ring grooves among one another is done by sealing elements (Fig. 8-73, Pos. 5). The hydraulic connection for case drain, house brake and the track tensioning cylinders is done via the ports (Fig. 8-73, Pos. L, St, K1 and K2). Entering of dirt is prevented by the seal ring (Fig. 8-73, Pos. 6) and the collar of the cover (Fig. 8-73, Pos. 3). The rotor (Fig. 8-73, Pos. 1) is at the top and bottom section guided in the housing by the guide rings (Fig. 8-73, Pos. 7).
The letters punch marked, beside the ports are marked as they are used in the hydraulic diagram. Task The rotary distributor (joint) permits a hydraulic connection between the superstructure and the undercarriage, that means between the rotating and the stationary part.

The spring loaded multi-disk brake is a safety brake; applied by spring force and released by oil pressure.
Hydraulics for the travel circuit
Function Brake applied: By means of toothings, the outer disks (Fig. 8-76, Pos. 11) are engaged to the housing (Fig. 8-76, Pos. 1), the inner disks (Fig. 8-76, Pos. 10) to the disk carrier / drive sleeve (Fig. 8-76, Pos. 9). Inner and outer disks are pressed together by the piston (Fig. 8-76, Pos. 4) with the force of the springs (Fig. 8-76, Pos. 7). This results in a fixed connection between housing and inner disk carrier / drive sleeve (Fig. 8-76, Pos. 11). Brake released: Pressure oil runs through port (Fig. 8-76, Pos. 5) to the chamber between intermediate ring (Fig. 8-76, Pos. 2) and piston (Fig. 8-76, Pos. 4). When the resulting force of the oil pressure exceeds the force of the compression springs, the piston is moved away form the brake disks to the motor flange. Now the disk are not longer pressed against each other, the brake is released. The minimum releasing pressure is 19-20 bar, the maximum permissible pressure 60 bar. The ZOLLERN parking brake is a "dry brake", no oil is permissible in the housing / on the brake disks.
WARNING WARNING The parking brake in the L&S gearbox has a similar design, but is a so called "wet brake" with an oil filling in the brake housing.
NOTE: For more information refer to the OPERATION AND MAINTENANCE MANUAL of the corresponding machine.

OPERATING HYDRAULICS
Version 2010/1
OPERATING HYDRAULICS
Hydraulics for the travel circuit
Task Travel brake valves control the oil flow from the hydraulic motor to the tank depending on the operating pressure. This braking action prevents the motors from overspeeding and cavitation. Function Spring force keeps the spool in the lowest flow position. With increasing operating pressure, the opening for the return oil flow becomes larger. On its way to the hydraulic motor, the oil flows from A to A1 and from B to B1 respectively, depending on the selected travel motion. Example Operating pressure at port A moves the spool (Fig. 8-77, Pos. 1) against the force of the spring (Fig. 8-77, Pos. 2) and opens the way for the return oil (Fig. 8-77, Pos. B1 to B). The check valve (Fig. 8-77, Pos. 3) prevents a direct oil flow from B1 to B. If the operating pressure decreases to such an extend that the spring force overcomes the pressure, the flow to the tank becomes restricted, resulting in braking the travel motion of the machine.

3. Secure the adjustment by tightening lock nut (Fig. 8-80, Pos. 2) and replace cap (Fig. 8-80, Pos. 1). 4. Re-check pressure setting. NOTE: It is important that the complete MRV valve and the SRV valve is firmly tightened (with 300 Nm). Otherwise internal leaks could occur, which result in: problems of correct adjustment, loud flow noises and hydraulic temperatures higher than normal.
3. Start the engine and let it run at high idle. 4. Carefully engage the desired travel motion and keep the pedal in final position to built up max. pressure. 5. Slowly increase the MRV pressure while observing the pressure gauge. The displayed value must remain at 310+5 bar. If the gauge shows a smaller or greater value, the SRV must be adjusted. NOTE: A faulty anti-cavitation valve (Fig. 8-80, Pos. 68.3 + 68.4, 68.6 + 68.7) or a leaking seal of the rotary joint (Fig. 8-80, Pos. 19) can influence the SRV pressure reading / setting.

General information The hydraulic track tensioning system automatically ensures the correct tension of the tracks. The track tensioning pressure (35 bar) provides the force to move the guide wheels to the front until the correct track tension is obained. The track safety function is controlled by valve block 130 with a double stage valve (35/310 bar). Pressure peaks due to external forces acting on the idlers will be absorbed by means of the pressure accumulators of the first (31 bar / 89.1 + 89.2) and second stage (150 bar / 82.1 + 82.2). Heavy shocks and high pressure peaks will be eliminated by the double stage valve of the 310 bar section in the valve block (130).
CAUTION After the assembly and during comissioning, before the shovel moves for the first time, each track tensioning cylinder has to be bled via the test ports (29.1 / 29.2 / 29.5 / 29.6) until air-free oil is draining off.
CAUTION Under normal operating conditions, the shut-off cocks (62.2 & 62.3) inside the side frames must always be open. Only for service or repair reasons, the cocks may be shut.
CAUTION The accumulators (89.1, 89.2, 82.1, 82.2) are to be maintained frequently (every 3000 hours) because of the gas pressure charge. See KMG tool catalogue for the charging tool box. After 30,000 hours, the accumulators are to be replaced by new ones.

HYDRAULIC TRACK TENSIONING SYSTEM
Functional description
X2 pressure (45 bar) is supplied by the travel parking brake circuit via valve 57Q516 in case the access ladder and the refilling arm are in upper end position. The pressure for the track tensioning system is limited to 35 bar by the pressure reducing valve (47) with a built-in non-return valve to prevent high pressure peaks in the pilot pressure circuit. When the tensioning cylinders (83.1 – 83.4) are moved in by external forces, the non-return valves (137.1 & 137.2) will be closed. A certain amount of the displaced oil from the tensioning cylinders is taken up by the pressure accumulators First stage: At a pressure higher than 31 bar, oil is taken up by the membrane accumulators (89.1 & 89.2) mounted at the side frames. Second stage: At a pressure higher than 150 bar, oil is taken up by the bladder accumulators (82.1 & 82.2) in the middle of the car body. The system pressure can rise up to 310 bar according to the setting of the double stage valve (140) inside the valve block (130). When the external forces fall below the forces of the track tensioning cylinders, the oil taken up by the accumulators is pushed back into the track tensioning cylinders (83.1 – 83.4). If not the whole amount of oil could be taken up the accumulators beforehand, oil is added from the pilot pressure circuit (35 bar) when the tensioning cylinders move in their initial position.

Description The pressure double stage valve is a remote controlled secondary relief valve at 310 bar. Function The valve poppet (Fig. 9-3, Pos. 2) is connected to port "P" via jet bores (Fig. 9-3, Pos. 11 and 12). If static pressure increases above the set pressure value, the valve poppet (Fig. 9-3, Pos. 2) opens and allows the oil to flow freely to the tank (Fig. 9-3, Pos. T1). This oil generates a pressure drop in the spring chamber of the main spool, the closing force of the spring (Fig. 9-3, Pos. 6) is cancelled, and the main piston (Fig. 9-3, Pos. 5) opens to allow the oil flow to the tank (Fig. 9-3, Pos.

Ensure that the access ladder and the refilling arm are in the upper end position (as the pre-condition for releasing the travel parking brake). 4. Read the pressure (nominal value: 55 bar). 5. Stop the engine. 6. The pressure should now drop to 0 bar because solenoid valve is de-energized, allowing the oil to flow back to the tank. 7. Disconnect the pressure gauge. NOTE: If the pressure reading differs substantially from the nominal value, the pre-set pressure reducing valve is presumably defective and should be replaced.

ACCESS LADDER, HYDRAULICALLY OPERATED
Function of Hydraulically Operated Access Ladder
Prime drive is running The pump (Fig. 10-2, Pos. 8.1) delivers the oil through the filter (Fig. 10-2, Pos. 33) to port A of the pressure relief valve (Fig. 10-2, Pos. 252.2). The pressure relief valve (Fig. 10-2, Pos. 252.2) maintains the adjusted pressure of 60+3 bar, called "X4“-pressure. By the function of pressure relief valve (Fig. 10-2, Pos. 252.1), the “X4“-pressure will be reduced to 45+3 bar (called "X2“-pressure) and is present at port P of solenoid valve 57Q623a/b. If solenoid valve 57Q623a or b is energized, the oil flows to the cylinder, and the ladder will move up or down. By the function of shuttle valve (Fig. 10-2, Pos. 258.4) both service lines are connected to safety valve (Fig. 10-2, Pos. 258.3), which limits the pressure to 70 bar. Return oil from cylinder (Fig. 10-2, Pos. 101) flows back via solenoid valve 57Q623a/b to solenoid valve 57Q625. 57Q625 = ON => Maximum cylinder speed, return oil flow is not restricted when both proximity switches 70B122 and 70B091 are not activated (ladder between top and bottom end position) 57Q625 = OFF => Reduced cylinder speed, return oil flow is restricted by orifice (Fig. 10-2, Pos. 258.7) when one of the proximity switches 70B122 (ladder up) or 70B091 (ladder down) is activated (i.e. cushioning function just before the final upper or lower end position is reached). If the ladder is in the “top position”, the activated sensor 70B122 de-energizes 57Q625 and energizes 57Q623a, with the result that the cylinder of the ladder is always charged (held) with pressure in this position. If switch 70S084 is in neutral position and the ladder is in “bottom position”, sensor 70B091 de-energises all solenoids (Fig. 10-2, Pos. 57Q625 and 57Q6123 a+b) and the ladder is “blocked”.

ACCESS LADDER, HYDRAULICALLY OPERATED
Function of Hydraulically Operated Access Ladder
Engine is not running and the ladder is in the “final upper position” With switch (70S084) activated in position "ladder down", the solenoid valves 57Q623b and 57Q625 are energized. 57Q6123b connects the piston side of the cylinder to the return line, so that the oil can return to the tank without resistance. Now the ladder can move down on its own (due to the force of gravity). The operator has to push the ladder slightly until it starts moving down on its own. In case the operator switches off the key switch (20S001), the "ladder down" function will be available via the MTC for approx. 30 min. After this time, the self-holding circuit (11Q100) switches off the MTC, and the travel alarm sounds twice. After that, the key switch (20S001) has to be switched on again for lowering the ladder. In case the operator switches off the key switch (20S001), and acitvates switch (70S084) in position "ladder down" until the ladder reaches the bottom end position (70B091 active), the self-holding circuit (11Q100) switches off the MTC after 2 minutes, the travel alarm will then sound twice.
WARNING z
Make sure that there are no obstacles in the moving range of the ladder! Stop raising the ladder by releasing the control switch (70S084) if there are any obstacles in the moving range!
z
Mount the ladder only in completely lowered position!
z
Do not lift persons or objects (tools) with the hydraulic access ladder! Serious injury or death could occur!

Enabling switch 20S094 for the hydraulic service arm operation
Basics The hydraulically operated service arm for diesel driven machines is primarily important to refuel the machine easily. Therefore, it is important to have a basic central refilling system directly connected to the service truck. In order to move the service arm, first of all it is necessary to move the service arm enabling switch 20S094 at the cabin dashboard into position "1". After that, the service arm can be lowered/raised by pulling switch 55S087. NOTE: As long as the pull switch 55S087 is activated, the service arm continues to move up/down. If the pull switch is released, the service arm stops. NOTE: When the service arm enabling switch 20S094 at the cabin dashboard is switched to ON position ("1"), pilot control for shovel movements is switched to OFF.
WARNING Before initiating a service arm movement, make sure nobody is in range of the moving arm.

CENTRAL REFILLING SYSTEM (SERVICE ARM)
Function
Pre-condtion: the engine is running. NOTE: In addition to the hydraulic diagram in Fig. 11-2, also see the respective electric circuit diagram. The pump (Fig. 11-2, Pos. 8.1) delivers oil through filter (Fig. 11-2, Pos. 33) to port A of pressure relief valve (Fig. 11-2, Pos. 252.2). The pressure relief valve (Fig. 11-2, Pos. 252.2) maintains the adjusted pressure of 60+3 bar, called X4 pressure. By means of the pressure relief valve (Fig. 11-2, Pos. 252.1), the X4 pressure will be reduced to 45+3 bar (called X2 pressure), that is present at port P of solenoid valve 57Q624a/b. If the solenoid valves 57Q624a and 57Q624c are energized, pressurized oil flows to the piston side of the service arm cylinder, and the service arm will move up. If the solenoid valves 57Q624b and 57Q624c are energized, pressurised oil flows to the rod side of the service arm cylinder, and the service arm will move down. Under working conditions, solenoid valve 57Q624c is permanently energized to hold the service arm in the upper position under pressure. When the solenoid valve is de-energized by key switch 20S001 in OFF position, the service arm position is held by the non-return valve in solenoid valve 57Q624c. All solenoid valves 57Q624a/b and c are MTC controlled. The pull switch 55S087 is also connected to the MTC and acts as a remote control. The service arm can only be moved down or up with activated key switch 20S001 and activated "service arm enabling switch" 20S094 in the operators cab. The proximity switch 55B023 signalizes the MTC that the service arm is in the upper position. If the service arm enabling switch 20S094 is activated, the pilot pressure is cut off. Pilot pressure is also cut off when the service arm is out of range of the proximity switch 55B023 in order to prevent damage to the lowered service arm.

VEHICLE HEALTH MONITORING SYSTEM (VHMS) & MTC CONTROL SYSTEM
General
The Vehicle Health Monitoring System (VHMS) is an electronic on-board monitoring system which includes the functions REAL TIME MONITOR, basic adjustments, and history reporting. Details are as follows: z
System and component monitoring based on fault code detection and storage of faults and other events, incl. trend snapshot data etc.
z
Selected subsystems and components, generation of trending, histogram, and cumulative data to be used as a predictive maintenance aid.
z
PC-based downloads via VHMS Technical Analysis Tool Box.
z
Single serial data connection to the MTC controller, and CAN bus transfer between VHMS controller and VHMS monitor MH801.
z
MTC evaluation ON/OFF function for testing and troubleshooting.
Operating Principle The VHMS system with a keyboard below the monitor allows comfortable operation and quick access to all information about the machine status and maintenance calls. The Diesel engine, a Komatsu SDA16V160 (QSK 60), is equipped with ECMs (Electronic Control Modules). This control system is called QUANTUM. For communication with the shovel control system the Quantum system is connected to the CAN bus #1. Condition monitoring on the shovel systems is established by the MTC (Master Turbo Controller), also called X2Controller, in serial connection with the VHMS controller. The MTC is equipped with a read & write memory and a real time monitoring system. The access to the VHMS controller is established via laptop and a serial interface, using the respective software. The control system components VHMS & monitor, MTC-Controller & nodes, and Quantum are connected as follows: VHMS Quantum
CAN bus #1
MTC-Controller Nodes
internal CAN bus
MTC-Controller VHMS-Controller
RS232 (serial connection)
VHMS-Controller => VHMS monitor MH801
CAN bus #2
As optional equipment the ORBCOMM and the MODULAR MINING SYSTEM are available. View onto the VHMS monitor with key pad in the dashboard

MTC-FIRMWARE AND SOFTWARE
The MTC is programmed with Firmware and Software. FIRMWARE The Firmware internally operates and manages the MTC unit, independent of the kind of the machine. SOFTWARE The Software is a machine-specific application which manages the excavator’s control system. Therefore it is essential that the Software version and the machine model properly fit together. It is possible to replace the programs (Firmware and Software) of the MTC. For such a procedure a specific version of the CoDeSys software must be installed on the used laptop. Via LAN connection such a software upload can be done comfortably. The CoDeSys software can also be used as a Visualization, which is an important tool for troubleshooting. For more details of the CoDeSys Visualization refer to the Visualization User Manual and to the Troubleshooting Manual of your machine.

GENERAL CAN BUS DESCRIPTION
The comparison of the wiring in a conventional control circuit and in a control circuit with CAN bus shows that the total length of the wiring between the controller and the electrical components in the CAN bus system is visibly shorter. Also the number of connectors is reduced, as several cable sections in the wiring between the controller and the machine components are no longer needed. In a CAN bus system all system components (input & output) are connected to a common data line via short branch lines. Therefore the system wiring is reduced and additional components may be connected easily.
14.8.1.2
Global Layout of the Internal CAN bus
CAN BUS TROUBLESHOOTING
The CAN bus system is equipped with effective selfdiagnosis tools. CAN troubles are displayed via the VHMS monitor and/or blinked out at the MTC-controller. With the help of a visualization software the location of any trouble can easily be determined. For troubleshooting in the CAN bus system a special CAN-Test Box is available. For details refer to the Tools and Accessories Catalogue. For the appropriate and qualified troubleshooting procedures refer to the TROUBLESHOOTING MANUAL of your machine.
The interfaces between the CAN bus and the electrical machine components are called Nodes. It is a fundamental idea of the CAN bus layout that the nodes are as close to the machine components as possible. However, the data flow must be controlled by an access method (protocol) in order to manage the well organized data transfer in one common data line. The MTC unit (refer to section 14.7 on page 14-100) and the Nodes (refer to section 14.9 on page 14-112) are essential components for the control and mangement of the CAN bus system. The status information from the electrical components as well as the control signals from the MTC are not continuously present in the CAN bus cable. Status information and control signals of each component are packed in data packages which are called Data Frames. These Data Frames are sent through the CAN bus periodically in small fractions of a second. The control components MTC & Nodes send and receive the Data Frames. Also they organize and manage a safety system, to make sure that defined and complete information packages are received by the designated components. Each Data Frame contains a protocol for its identification. A CAN bus cable consists of only 3 wires, which are: z
CAN high (H)
z
CAN low (L)
z
Shield
In a CAN bus system 2 voltages are present. Depending on the kind of system the CAN high voltage is in a range of up to approx. 6V. The CAN low voltage is up to approx. 3.5V.

CAN BUS END RESISTOR
A CAN bus does not build a closed wiring circuit as a conventional electrical circuit system in general does. As a result there is an "open" end. At this end the wires CAN high and CAN low must be connected by an End Resistor. The resistance of these End Resistors is 120 Ω each. A CAN bus can be split, and in this case an End Resistor needs to be connected to each end of the CAN bus. The following chart gives an overview over the fitted End Resistors on your machine.

General Overview CLS & SLS
GENERAL DESCRIPTION
For maximum machine reliability and maximum lifetime the principal bearing points must be frequently lubricated with a sufficient amount of specified lubricant. For best lubricating reliability with minimum maintenance there are automatic lubrication systems which are controlled by the MTC. They lubricate all connected lubrication points within adjustable time intervals and with the required amount of lubricant. The automatic lubrication starts as soon as the machine runs at high idle. The excavator is equipped with 2 independent lubrication systems: CLS The CLS (Central Lubricating System) supplies the attachment bearings and the swing ring bearing with grease. SLS The SLS (Swing ring gear Lubrication System) supplies the open gear of the swing ring teeth and the lower bearings of the swing gearboxes with grease. These two independent lubrication systems are necessary because the attachment bearings and the open gear teeth require different types of lubricant.

AUTOMATIC LUBRICATION SYSTEMS
GENERAL INFORMATION ON CLS
A hydraulic driven lubricant pump (Fig. 15-3, Pos. 1 & 11) pumps grease from a barrel (Fig. 15-3, Pos. 10) through pipes (Fig. 15-3, Pos. 8) or hoses to the injectors (Fig. 15-3, Pos. 18). These injectors pump a defined quantity of grease to the lubrication points. After all injectors delivered their grease quantity to the lube points, the grease pump stops and the next lubrication cycle will start after an adjusted time period (pause time). The central lubrication system is only active if the engine is running at high idle. z
After the pilot pressure has been reduced it passes to the hydraulic cylinder (Fig. 15-3, Pos. 1) which operates the grease pump (Fig. 15-3, Pos. 11).
z
The hydraulic cylinder (Fig. 15-3, Pos. 1) operates the grease cylinder with 19 – 21 double strokes per minute. In that way 612 - 680 cm3 (approx. 550 - 612 g) of lubricant are delivered per minute.
z
With the vent valve (Fig. 15-3, Pos. 7) closed, the pump continues to cycle until the maximum pressure is achieved and the injectors (Fig. 15-3, Pos. 18) have metered grease to the lubrication points. The pressure in the lubrication system is 180 bar.
z
When the maximum system pressure is reached, the end-line switch (Fig. 15-3, Pos. 20) will open.
z
The open end-line switch (Fig. 15-3, Pos. 20) signals the controller that the pumping cycle has to be stopped.
z
The solenoid valve (Fig. 15-3, Pos. 2) is de-energized and the hydraulic oil stops flowing to the pump (Fig. 15-3, Pos. 1).
z
The MTC starts to count down a fixed time (pressure holding time) and an adjustable pause time (rest time between the automatic lubrication cycles).
z
The vent valve (Fig. 15-3, Pos. 7) is still closed (solenoid active) and the lubricant pressure will be kept on the pressure (a slow pressure decrease is normal).
z
If the countdown for the pressure holding time (5 min) is finished the controller terminates the signal to the solenoid valve (Fig. 15-3, Pos. 7).
z
If the vent valve (Fig. 15-3, Pos. 7) is de-energized, it opens and allows the grease pressure to drop to zero.
z
All injectors move into their initial position by spring force and recharge themselves for the next lubricant cycle.
z
The system is at rest now and ready for another lube cycle.
Manual lube activation A manual activation of the lubrication systems is possible by operating switch 20S124 (CLS) or 20S126 (SLS) at the dashboard. The MTC counts the number of switch activations and operates the lube system successively, as often as the switch was activated. The system rests between the lube cycles according to an adjustable pause time (pressure relief time). After the previous loop is completely finished and after the pause time is experied the next lubrication cycle can start if the engine is running at high idle (CLS/SLS) and if a slew movement was activated (SLS).

AUTOMATIC LUBRICATION SYSTEMS
GENERAL INFORMATION ON SLS
The swing circle gear lubrication system (SLS) uses a special dummy wheel to apply the gear grease onto the swing circle gear. All other components between the grease barrel and the injectors are comparable to the central lubrication system (CLS). With each lube cycle the dummy wheel receives grease from two or more parallel connected injectors. After the injectors delivered their gear grease quantity through the dummy wheel to the swing ring gear, the grease pump stops and the next lubrication cycle will start after an adjusted time period (pause time). The swing circle gear lubrication system is only active if the engine is running at high idle and if the slew function is activated. z
After the pilot pressure has been reduced it passes to the hydraulic cylinder (Fig. 15-4, Pos. 11) which operates the grease pump.
z
The hydraulic cylinder (Fig. 15-4, Pos. 1) operates the grease cylinder with 19 - 21 double strokes per minute. In that way 612 - 680 cm3 (approx. 550 - 612 g) of lubricant are delivered per minute.
z
With the vent valve (Fig. 15-4, Pos. 7) closed, the pump continues to cycle until maximum pressure is achieved and the injectors (Fig. 15-4, Pos. 18) have metered grease to the dummy wheel. The pressure in the lubrication system is 180 bar.
z
When the maximum system pressure is reached, the end-line switch (Fig. 15-4, Pos. 20) will open.
z
The open end-line switch (Fig. 15-4, Pos. 20) signals the controller that the pumping cycle has to be stopped.
z
The solenoid valve (Fig. 15-4, Pos. 2) is de-energized and the hydraulic oil stops flowing to the pump (Fig. 15-4, Pos. 1).
z
The MTC starts to count down a fixed time (pressure holding time) and an adjustable pause time (rest time between the automatic lubrication cycles).
z
The vent valve (Fig. 15-4, Pos. 7) is still closed (solenoid active) and the lubricant pressure will be kept on the pressure (a slow pressure decrease is normal).
z
If the countdown for the pressure holding time (5 min) is finished the controller terminates the signal to the solenoid valve (Fig. 15-4, Pos. 7).
z
If the vent valve (Fig. 15-4, Pos. 7) is de-energized, it opens and allows the grease pressure to drop to zero.
z
All injectors move into their initial position by spring force and recharge themselves for the next lubricant cycle.
z
The system is at rest now and ready for another lube cycle.
Manual lube activation A manual activation of the lubrication systems is possible by operating switch 20S124 (CLS) or 20S126 (SLS) at the dashboard. The MTC counts the number of switch activations and operates the lube system successively during swing movement, as often as the switch was activated.

Explanation
a-b
If the engine is running at high idle a lubrication cycle starts after the pause time is expired or if the switch for manual lubrication 20S124 (CLS) or 20S126 (SLS) was activated. For SLS there is also the precondition that the control lever for "Swing" is moved out of its zero position. The MTC activates the solenoid valve and the pilot pressure (X4 pressure) starts to move the oscillating cylinder. At the same time the vent valve is closed and the lubrication pressure starts to increase. This time segment for building-up the pressure in the lubricant line is fix-programmed in the MTC and it is not adjustable.
b
After all lubrication points have been lubricated there is a pressure rise which opens the end-line switch when the max. pressure is reached. At this time the MTC de-energizes the solenoid valve and stops the oscillating cylinder of the lubrication pump. Now the pressure increasing phase is finished and the pressure holding time starts. The switch point of the end-line switch is 180 +5 bar.
b-c
At this time the MTC starts to count the pressure holding time (5 min) which is fix-programmed in the controller. This time segment is not adjustable. During the pressure holding time the vent valve is kept closed and the pressure is kept at its max. level of 180 bar.
c
After the pressure holding time (5 min) is expired, the end-line switch closes and the vent valve opens. Now the pressure holding phase is finished and the grease pressure is released back to the barrel.
c-d
The pressure release time is fix-programmed in the MTC. This time segment is not adjustable. It is necessary to drop the lubricant pressure completely to zero so the injectors can be recharged for the next lubrication cycle.
b - a’
The pause time prevents that the next lubrication cycle would start too early in case the switch for manual lubrication 20S124 (CLS) or 20S126 (SLS) was actived several times. The counting of the pause time starts at "b" when the end-line switch opens at max. line pressure. The next lubrication cycle starts after the pause time is expired. Preconditions: SLS/CLS: Engine running at high idle SLS only: Slew movement was activated Via the VHMS monitor the pause time is adjustable: CLS 10 - 60 minutes SLS 10 - 20 minutes

AUTOMATIC LUBRICATION MODE
A manual lubrication cycle can be activated via the switches 20S124 (CLS) or 20S126 (SLS) at the dashboard.
The lubrication systems are controlled and monitored complete by the program of the MTC. The MTC activates the outputs dependent on inputs and time-lines according to the programmed software. The Pause Time can be adjust in a specified range via the VHMS Real Time Monitor. Monitoring time and pressure relief time are fix-programmed. After a restart of the engine the SLS / CLS system first continues the residual time of the current pause time period before a new start of the grease system is possible. The lube system only starts if the engine is running at high idle.
MANUAL LUBRICATION MODE
In the Operator Mode a manual lube cycle can be started after a waiting period of 10 minutes. This timeline is independent of the Pause Time setting for the automatic mode, which is input via the VHMS monitor.
15.5.5.3
VHMS SERVICE MODE
As long as the VHMS Service Mode is activated the Pause Time is automatically reduced to 30 seconds. Test and adjustment works can be performed more comfortable if the Pause Time is shortened in the VHMS Service Mode. After return to the Operator Mode the Pause Time will be reset to the automatic period which has been adjusted on the VHMS monitor before.
VHMS Pause Time Settings CLS Pause time range: 10 - 60 minutes Standard setting: 15 minutes SLS Pause time range: 10 - 20 minutes Standard setting: 20 minutes

Lubricant inlet
The lubrication pump is a hydraulically driven seal free differential piston pump. The pump pumps lubricant at the up and down stroke but sucks lubricant only during the up stroke. The scoop piston at the pump bottom supports the main pump especially with high viscosity lubricants. There are only one dynamic seal at the piston rod on top of the pump pipe therefor less on wear and long service time. The lubrication pump is divided in two main components, the pump drive hydraulic cylinder and the pump. The pump drive and only the pump outlet are outside on top of the lubricant container, the pump itself is inside and reaches into the lubricant. The maximum possible lubricant pressure depend on the adjusted supply pressure. The pressure multiplication factor between supply pressure and maximum lubricant pressure is 6.55. The pressure reduction valve has to be adjusted to 45 bar. Example: 45 bar supply pressure x 6.55 = 295 bar lubricant pressure. During normal operation the end-line switch stops the pump before reaching this high pressure. For a sufficient lube pump operation 19 - 21 double strokes / min for the pump drive cylinder are required. Therefore the flow reducing valve has to be adjusted, refer to section 15.6.1 on page 15-22. Technical pump data Pump stroke

WORKING PRESSURE ADJUSTMENT
For a sufficient lubricating pump operation 19 - 21 double strokes / min of the pump drive cylinder are required. Therefore the flow reducing valve (Fig. 15-8, Pos. 3) has to be adjusted accordingly.
The pressure reducing valve (Fig. 15-8, Pos. 2) is mounted on the oscillation control block. It reduces the supply pressure to 45 ± bar.
Adjustment procedure
Adjustment procedure
1. Remove the connector from the vent valve (Fig. 15-8, Pos. 7), in order to avoid any pressure rise during the following test.
1. If not yet mounted install a test fitting in port M at the oscillation block, and connect a pressure gauge (0 - 60 bar)
2. Start the engine and run it at high idle.
2. Disconnect the quick-coupling (Fig. 15-8, Pos. 8) from the lubricant supply line in order to block the pump when it is started.
3. Manually switch ON the lube system by using switch 20S124 (CLS) or 20S26 (SLS) at the dasboard and count the double strokes per minute. Therefore remove the plug (Fig. 15-9, Pos. 1) from the pump cover (Fig. 15-9, Pos. 2) and watch the piston going up and down.
3. Start the engine and run it at high idle. 4. Manually switch ON the lube system. The gauge should indicate a max. pressure of 45 ± bar. If adjustment is required 5.

FUNCTION DESCRIPTION
Stage A
Stage D
Inlet pressure 0 bar Outlet pressure 0 bar
Inlet pressure relieved
The injector piston is in its normal, or rest position. Visible by the extracted indicator stem (2) which is blocked in final position by the set screw (1). The discharge chamber (8) is filled with lubricant from the previous cycle.
Stage B
After lubricant supply pressure (10) is relieved, the compressed spring (5) moves the slide valve (6) to the closed position. This opens the port from the measuring chamber (12) and permits the lubricant to be transferred from the top of the piston to the discharge chamber (8). The indicator stem (2) extract to its initial final stop of the adjustment screw (1). Now the injector is prepared for the next lubricant application.
Inlet pressure increasing from 0 to 180 bar Outlet: lubricant injection 0 - 180 bar Output volume: adjusted amount of lubricant Under the pressure of incoming lubricant via port (10), slide valve (6) is about to open the passage (9) leading to the piston (4). When the slide valve (6) uncovers the passage (9), lubricant is admitted to the measuring chamber (12) at the top of the piston (4), forcing the piston down. The piston (4) forces lubricant from the discharge chamber (8) through the outlet port (11) to the bearing. The indicator stem (2) retracts.
Stage C Inlet pressure at maximum 180 bar Output injection is finished As the piston (4) completes its stroke, it pushes the slide valve (6) past the passage (9), cutting off further admission of lubricant to the passage (9). Piston (4) and slide valve (6) remain in this position until lubricant pressure in the supply line (10) is vented (relieved) at the pump station. The indicator stem (2) is fully retracted and the adjusted amount of lubricant is injected to the bearing.

Connection of lubricant injectors
Description To increase the lubricant output volume, the injectors (1) are designed to be combined (2 or more injectors). A connector pipe (2) is used to connect two injectors (1). Lubricant from the first injector, outlet (b), is directed through the connector pipe (2) to the inlet (c) of the second injector. Both injectors are now connected, in order to lubricate one lubrication point via pipe (3). This connection is possible for both injector types (SL-1 and SL-11).
CAUTION When installing a fitting to an injector, always observe the maximum tightening torque of 14 Nm. Otherwise the fitting will be screwed too far into the injector and the injector piston movement will be blocked. As a result the grease supply will fail.
For the tightening procedure also refer to the PARTS & SERVICE NEWS AH10532 (latest edition). NOTE: In case of leakage use thread tape (Teflon®) or Loctite® when installing a fitting to any injector.

DESCRIPTION
Task By the function of the vent valve the pressure in the lubricant supply line is relieved, after a lubrication cycle is finished. The injector pistons move back into their initial positions. The valve is open if the solenoid is de-energized. Then port A is connected with port B. Function The solenoid isenergized when a lubrication cycle starts. The connection from A to B gets closed, thus a pressure build-up in the grease supply line is possible. The solenoid gets de-energized, as soon as a lubrication cycle is finished. This causes an opening of the connection A to B, thus the supply line to the lubricant barrel is open. The lubricant flows from A to B or vice versa along the main valve piston (Fig. 15-13, Pos. 5).

DESCRIPTION
Task The end-line pressure switch is the main part to monitor and to control the lubrication system. It stops the lubrication pump when the lubricant pressure reaches the max. adjusted pressure. Function One pressure control unit is installed in each lubrication system (CLS & SLS). The grease pressure, produced by the hydraulic barrel pump, acts also at the piston (Fig. 15-14, Pos. 1) If the force of the grease pressure exceeds the spring forces (Fig. 15-14, Pos. 4), the piston (Fig. 15-14, Pos. 1) is forced against the disk (Fig. 15-14, Pos. 2). Thus the contacts of the switch (Fig. 15-14, Pos. 5) are operated and an electric contact is given to the MTC. Any adjustment has to be done with the sleeve (Fig. 15-14, Pos. 6): Turning it clockwise - higher switch point Turning it counterclockwise - lower switch point

Lubricant Level Sensor
Function The sonar sensor sends a proportional current signal according to the distance between the sonar sensor and the grease level to the MTC. The sensor operates in a range of 320 to 950 mm. The min. distance means the lubricant barrel is full. In this case the signal current to the MTC is ~ 20 mA. The max. distance means the lubricant barrel is empty. In this case the sensor signal current to the MTC is ~ 4 mA. NOTE: The sonar sensor gets out of range if it comes in contact with grease. Therefore an overfilling of the grease barrel should be avoided. In case of a sensor malfunction (red LED at the sensor ON), remove the sensor and wipe off any grease from its lower surface. For the LED function in case of a sensor error see the following section.
15.11.1 DESCRIPTION
15.11.1.1 LEDS AT THE SONAR SENSOR
Task
At the upper collar (Fig. 15-18, Pos. b) the sensor is equipped with LEDs (red & yellow). The function of these LEDs is as follows:
The lubricant level sensor is an analog sonar sensor type. Lubricant maximum filling level monitoring is necessary to prevent an overfilling of the grease barrel via the refilling arm. The minimum grease level monitoring allows timely refilling of grease and it prevents the grease pump from running dry. General The analog level signal comes from the sonar sensor which is mounted on the cover of the lubricant pump station. The sensor is connected to the MTC. The MTC activates the "full" light if the grease level reaches the maximum. This indication light is mounted at the refilling arm. If a grease level of 10 - 15 % is reached the MTC generates the message Central lubrication system grease level too low or Slew gear lubrication system grease level too low. This allows grease charging in time, which prevents an unexpected breakdown. If the lubricant level reaches 0 % the MTC deactivates the lubrication pump and generates the message Central lubrication system empty or Slew gear lubrication system empty. Version 2010/1

15.12.1 DESCRIPTION The SLS system lubricates the open gear of the swing ring with special open gear lubricant. The lubricant pump station (Fig. 15-19, Pos. 1) is the same as for the CLS system. To apply the lubricant equally to the swing ring gear teeth (Fig. 15-19, Pos. A) a special lubrication pinion (Fig. 15-19, Pos. 9) close to the swing drive pinion is mounted. The lubrication pinion (Fig. 15-19, Pos. 9) distributes the lubricant from the injectors evenly to the teeth. Normally two or more injectors are parallel connected to supply the required amount of lubricant to the lubrication pinion. The pinion center shaft (Fig. 15-19, Pos. B) acts as a rotary joint and distributes the lubricant through radial bores only to those teeth witch are in contact with the swing ring gear teeth. Outlet bores (Fig. 15-19, Pos. B) at different pinion gear levels distribute the lubricant equally to the swing ring gear teeth (Fig. 15-19, Pos. A). To prevent unnecessary lubrication with the swing ring in park position, the SLS pump only starts to operate after "swinging" was activated with the control lever. All other SLS control and monitoring functions are the same as they are used in the CLS system.

Commissioning
15. After ~20 working hours check the lubrication systems. Check the lubrication points for sufficient grease. Check the swing circle lubricating, a small amount of grease must appear at the inner swing circle seal. Watch the cycle counter and compare it with the respective working hours. z
Example: Pause time setting = 30 minutes Working hours since the last check = 10 hours 10 h / 0.5 h = 20 cycles Compare with the indication of the cycle counter. There should be 20 –1 cycles, provided no manual cycle was activated.
16. Check the lubrication systems every day. Compare all lubrication points. There should be a well balanced small amount of fresh grease at each bearing seal or open bearing.
15.13.2 FINE ADJUSTMENT General Under normal circumstances the lubrication system - with the basic adjustment - applies more lubricant as required. 1. Find out the lubrication point with the lowest quantity of fresh grease. This point is the indicator for the following pause time fine adjustment. 2. Reduce the applied quantity by extending the pause time as much until a small amount of wet grease appears at the bearing seal or open bearing of the indicator point. Extend the pause time only in small steps (~2 - 5min). Between each step wait for 40 working hours or more and watch the lubrication points. 3. If there are one or more bearing points with too much grease, adjust the respective injector to a lower volume, refer to section 15.7.3 on page 15-25. Change the setting only in small steps (max. 1 - 2 turns clockwise). Between each step wait for 40 working hours or more and watch the lubrication points. Be careful, don’t turn the set screw too much in, and block the injector against moving. NOTE: Check the CLS every day (Daily Check)! The lubrication points of a correct adjusted Central Lubrication System have a well balanced small amount of wet grease. Never let the excavator operate with a grease shortage. Find out the reason for this shortage and eliminate this problem immediately.

If the teeth get a clear metallic look it is immediately necessary to apply fresh open ring gear lubricant. Find out the reason of this shortage and eliminate this problem immediately. The swing circle toothing of a correct adjusted SLS have a thin layer of open ring gear lubricant. There should be a small amount of fresh open ring gear lubricant around the tooth contact area.

Lubrication Pump Station (SLS)
General The swing circle gear lubrication system use a special dummy wheel to apply the gear grease on to the swing circle gear. All other components between grease barrel and injectors are the same as the central lubrication system. The dummy wheel receives by each lub cycle grease from two or more parallel connected injectors. After the injectors have pump its gear grease quantity through the dummy wheel to the swing ring gear the grease pump stops and the next grease cycle starts after a adjusted time (pause time). The swing circle gear lubrication system start only by running engine in high idle and active slew function. z
After the pilot pressure has been reduced it passes to the hydraulic cylinder which operates the grease pump.
z
The oil cylinder shuttle’s the grease cylinder at 18 – 20 double strokes per minute and delivering 612 – 680 cm³ (37.3 – 41.5 in³) of lubricant per minute (approx. 550 – 612 g / 19.64 – 21.45 oz.)
z
With the vent valve (Fig. 15-5, Pos. 9) closed the pump continues to cycle until maximum pressure is achieved and the injectors have transmitted lubricant to the dummy wheel. In most lubrication systems this is 185 bar (2630 psi. ).
z
When the maximum system pressure is reached the end-of-line switch opens.
z
The open pressure switch signals the controller to stop the pump cycle.
z
Solenoid valve (Fig. 15-5, Pos.4) are de-energized and the hydraulic oil stops flowing to the pump.
z
The controller starts to count down a fixed time (load holding time) and a adjustable pause time (rest time between the automatic lubrication cycles).
z
The vent valve (Fig. 15-5, Pos. 9) is still closed (solenoid active) and the lubricant pressure will be rest on pressure (slow decrease is normal).
z
If the count down of the load holding time is finished the controller terminate the signal to solenoid valve (Fig.15-5, Pos. 9).
z
Vent valve (Fig. 15-5, Pos. 9) is de-energized, it opens and allows the grease pressure to drop to zero.
z
All injectors move in the initial position by spring force and recharge itself for the next lubricant cycle.
z
The system is now at rest and ready for another lube cycle.
It is possible to activate the slew gear lubrication system manually by using switch S26 on the dashboard. The controller count the number of switch activatings and operate the system this number one by on provided the slew function was activated. The system rest between each cycles for a adjustable time (pressure relief time).

z
Grease pump (Fig. 15-7, Pos. 3)
The Propulsion cylinder (Fig. 15-7, Pos. 1) is connected to the pump piston (Fig. 15-7, Pos. 10). The lubricant pump pumps per stroke (up or down) lubricant through the pump tube (Fig. 15-7, Pos. 3) to the lubricant outlet port. The piston speed and force is adjustable via two valves mounted on the cylinder controlling block (Fig. 15-7, Pos. 2). The left hand valve is a adjustable flow regulation valve to limit the oil flow to the propulsion cylinder. This flow is responsible for the cylinder speed. The right hand valve is a pressure reducing valve to limit the maximum lubrication supply pressure. The stroke direction change automatically if the cylinder stops moving. Reach the cylinder its own stroke limit the moving direction change also if the cylinder stops by an external force. The maximum possible lubricant pressure depend on the adjusted supply pressure. The pressure multiplication factor between supply pressure and maximum lubricant pressure is 6,55. The pressure reduction valve has to be adjusted to 50 bar. Example: 50 bar supply pressure x 6,55 = 327,5 bar lubricant pressure. During normal operation the end line switch stop the pump before reaching this high pressure. For a sufficient lube pump operation 18 – 20 double strokes / min for the pump drive cylinder are required. Therefore the flow reducing valve has to be adjusted, refer to section 15.5 on page 15-38.

Task By the function of the vent valve the lubricant supply line gets pressure relieved, after the lubrication cycle is finished. The injector pistons move back into their initial position. The valve is open if the solenoid is de-energized. It means port A is connected with port B. Function The solenoid gets energized. When the lubrication cycle starts. The connection from A to B gets closed, thus a pressure build-up in the grease supply line is possible. The solenoid gets de-energized, as soon as the lubrication cycle is finished. This causes opening of the connection A to B, thus the supply line to the lubricant barrel is open. The lubricant flows from A to B or vice versa along the main valve piston (Fig. 15-8, Pos. 5).

General: Each injector can be manually adjusted with set screw (1) to discharge the precise amount of lubricant each bearing needs. Injectors are mounted singly at each bearing, or grouped in a manifold with feed lines supplying lubricant to the bearings. In each case, injectors are supplied with lubricant under pump pressure through a single lubricant inlet port (A). Two injector size are used on KMG machines. Both size can be used in the same circuit, their selection is made on the basis of bearing lubricant requirements.The injectors are externally adjustable so each bearing can receive the correct amount of lubricant. Each injector incorporates an indicator pin that gives visual confirmation the injector is operating correctly. When necessary, troubleshooting is the simple process of checking indicator pins. Via service port (7) it is possible to lubricate the bearing with a manual operated grease gun. Open only cab nut (7a) of service port (7) to get access to the grease nipple. The cup nut (7a) must be replaced after manuel lubrication to plug and protect the nipple.

Function steps: Stage A: Inlet pressure 0 bar, Outlet pressure 0 bar The injector piston is in its normal, or rest position. Visible by the extracted indicator stem (2) which is blocked in final position by the set screw (1). The discharge chamber (8) is filled with lubricant from the previous cycle.
Stage B: Inlet pressure increasing from 0 to 180 bar, Outlet: lubricant injection 0 - 180 bar, Output volume: adjusted amount of lubricant Under the pressure of incoming lubricant via port (10), slide valve (6) is about to open the passage (9) leading to the piston (4). When the slide valve (6) uncovers the passage (9), lubricant is admitted to the measuring chamber (12) at the top of the piston (4), forcing the piston down. The piston (4) forces lubricant from the discharge chamber (8) through the outlet port (11) to the bearing. The indicator stem (2) retracts. Stage C: Inlet pressure at maximum 180 bar Output injection is finished As the piston (4) completes its stroke, it pushes the slide valve (6) past the passage (9), cutting off further admission of lubricant to the passage (9). Piston (4) and slide valve (6) remain in this position until lubricant pressure in the supply line (10) is vented (relieved) at the pump station. The indicator stem (2) is fully retracted and the adjusted amount of lubricant is injected to the bearing. Stage D: Inlet pressure relieved z
After lubricant supply pressure (10) is relieved, the compressed spring (5) moves the slide valve (6) to the closed position. This opens the port from the measuring chamber (12) and permits the lubricant to be transferred from the top of the piston to the discharge chamber (8). The indicator stem (2) extract to its initial final stop of the adjustment screw (1). Now the injector is prepared for the next lubricant application.

Principle of Operation By mean of a lubricant pump, the lubricant is supplied to the centered bore hole (B) of the lubricating pinion (R). Bore hole (B) must be perfectly aligned to the swing circle gear (A) to be greased, so that lubricant leaves the tooth flank always at matched condition. The grease outlet (D) of the lubricating pinion is arranged at a different angle for each tooth, so that the lubricant is distributed in a uniform and perfect manners on the tooth flank of the drive pinion to be lubricated. The pinion propulsion is by the slew gear. The pinion bearings are lubricated himself by the gear grease. The picture shows an example with one pinion only. There are also machines which will have two pinion (dummy wheel).

Function of a lubrication cycle. (Illustration Z24042d). PT - phase With the pump and controller system in a rest sate a pre-set pause time interval occurs as determined by PLC: Diagram position (a): A 24Vdc signal from the PLC activate solenoid valve (2) that opens and activate the lubrication pump (*). As solenoid valve (2) opens, hydraulic oil flow through the pressure reducing valve (4), it lowers the hydraulically pilot oil pressure to the operating range of the hydraulic driven lube pump. The reduced pilot oil pressure operates now the grase pump. The oil cylinder shuttle the grease cylinder at 18 - 20 double strokes per minute and delivering 212 680cm³ (37.3 - 41.5 in³) of lubricant per minute (approx. 550- 612 / 19....64 - 21.45 oz.)

Adjustments lubricating pump pressure Maximum pump operating pressure (P) The pressure reducing valve (3) mounted in the oscillation control block reduce the pump drive cylinder pressure internally. The maximum allowed pressure is 45 bar but there is no direct pressure check required. The pressure ratio is 6,55 to 1, that means 45 bar supply pressure result in 295 bar maximum lubricant pressure. At the end line pressure switch the pressure should be 180 ±5bar. With the lubricant line resistance and different lubricant viscosity the pressure at the lubricant pump must be higher as 180 bar. 220 – 250 bar pump pressure (pressure gauge at lubrication station) is sufficient to achieve the 180 bar end line pressure after line resistance and different lubricant viscosity.
Procedure: 1. Disconnect quick coupling (10), so the pump supply line from the pump to the injectors is blocked. 2. Start engine and run at high idle. 3. Activate the required lube system manually, the gauge (14) should show 220-250 bar. 4. If adjustment is required: 5. Loosen lock nut (3.1) 6. Turn adjustment (3) until the right pressure is shown at the gauge (7) turn set screw ccw to lower pressure and cw to increase the pressure until the required pressure is achieved. 7.

In each case, injectors are supplied with lubricant under pump pressure through a single supply line (10). Two injector size used. Both size can be used in the same circuit, their selection is made on the basis of bearing lubricant requirements.The injectors are externally adjustable so each bearing can receive the correct amount of lubricant. Each injector incorporates an indicator pin that gives visual confirmation the injector is operating correctly. When necessary, troubleshooting is the simple process of checking indicator pins. Via service port (7) it is possible to lubricate the bearing with a manual operated grease gun. Open only cab nut (7a) of service port (7) to get access to the grease nipple. The cup nut (7a) must be replaced after manuel lubrication to plug and protect the nipple.

1. Connect pressure gauge (0-400 bar) to check point near by the end line switch. There is only a T-union with one plugged port. Open this port and mount a adapter test union to connect the pressure gauge. NOTE: Use an other gauge as for checking hydraulic pressures because the gauge remains filled with grease after the test. 2. Start engine. 3. Start a lube cycle with the dashboard switch S24. 4. Watch pressure gauge. At a pressure of 180+10 bar the end-line switch must react and the lubricants pump must be stopped. *) NOTE: *) If at the same time the pressure shown at the built-in gauge is noted down, this pressure can be taken for later on checks as a reference pressure. But be careful this pressure is higher than the pressure shown at the test gauge because of the long distance between pump and end of the supply line. NOTE: 180 bar is the normal setting. Under particular circumstances it may be necessary to increase the pressure slightly. If re-setting is required: 1. Screw out screw (Fig. 15-22, Pos. 1) and take off cover (Fig. 15-22, Pos. 2). 2. Alter the spring tension with adjustment screw (Fig. 15-22, Pos. 3) that the switch operates at 180 bar. 3. Install cover (Fig. 15-22, Pos. 2) and screw (Fig. 15-22, Pos. 1).

15. After ~20 working hours check the lubrication systems. Check the lubrication points for sufficient grease. Check the swing circle lubricating, a small amount of grease must appear at the inner swing circle seal. Watch to the cycle counter and compare it with the respective working hours. z
Example: Pause time setting = 30 min Working hours since the last check = 10 hours 10 h / 0.5 h = 20 cycle Compare with the number of cycle counter it should be 20 –1 cycle, provided no manual cycle was activated.
16. Check the lubrication systems every day. Compare all lubrication points. There should be a well balanced small amount of fresh grease at each bearing seal or open bearing.
15.7.2
FINE ADJUSTMENT
General In normal circumstance the lubrication system apply with the basic adjustment more lubricant as required. 1. Find out the lubrication point with the lowest quantity of fresh grease. This point is the indicator for the following pause time fine adjustment. 2. Minimize the apply quantity by extending of the pause time as much as a small amount of wet grease appears at the bearing seal or open bearing from the indicator point. Extend the pause time only in small steps (~2-5min). Between each step wait 40 working hours or more and watch the lubrication points. 3. If there one or more bearing points with to much grease adjust this respective injector to a lower volume, refer to section 15.5.2 on page 15-42, change setting only in small steps (max. 1-2 turn clock wise) Between each step wait 40 working hours or more and watch the lubrication points.

Part II contains Safety Notes and Precautions which should be followed during troubleshooting work. Furthermore fundamental requirements and points to remember when troubleshooting are given. Also you find recommendations concerning the sequence of working steps, checks which should be done before troubleshooting, how to handle electric and hydraulic equipment, and how to perform basic working procedures. Part III provides you with information about mounting locations of components, different connector types as they are used in your machine, and standard values for electrical components as a quick reference. In Part IV troubleshooting charts are listed in the numerical sequence of trouble codes as they are stored in the control system. The monitoring system follows the logic of defined flow charts. If predetermined conditions occur, the VHMS displays relevant trouble codes and messages. In Part V troubleshooting charts are listed for various engine electrical, mechanical, and hydraulic problems. These charts are showing symptoms of any malfunction which the monitoring system can not detect under the particular conditions. Therefore these malfunctions are not indicated by stored trouble codes or messages via VHMS. Nevertheless the troubleshooting charts in Part IV and Part V can not cover all eventual malfunctions which may possibly occur. In such cases a general inspection of the suspected system is necessary. Furthermore, it is not necessary that you strictly follow the given troubleshooting charts in every case. It is important to find the cause for any trouble in the easiest way and in the shortest time. In most times the relevant flow chart will help you to be successful.

Precautions against work which you are not used to or you are used to too much
Preparations for work 1)
Before adding oil or making any repairs, park the machine on hard and level ground. Isolate the machine according to local regulations.
2)
Before starting work, make sure that the work equipment is lowered to the ground. Also make sure that the maintenance safety switch (S58) is switched OFF and locked with a padlock. In addition hang up warning signs.
3)
When disassembling or assembling, support the respective unit with blocks, jacks, or stands as necessary before starting work.
4)
Remove all mud and oil from the steps or other places used to get on and off the machine. Always use the handrails, ladders or steps when getting on or off the machine. Never jump on or off the machine. If it is impossible to use the handrails, ladders or steps, use a stand to provide safe footing.
Precautions during work 1) Before disconnecting or removing components of the oil, water, or air circuits, first release the pressure completely from the circuit. When removing the oil filler cap, a drain plug, or an oil pressure pickup plug, loosen it slowly to prevent the oil from spurting out. 2) The coolant and oil in the circuits are hot when the engine is stopped, so be careful not to get scalded. Wait for the oil and coolant to cool before carrying out any work on the oil or water circuits.

3) Before starting work, stop the engine. When working on or around a rotating part, in particular, stop the engine. When checking the machine without stopping the engine (measuring oil pressure, revolving speed, temperature, etc.), take extreme care not to get rolled or caught in rotating parts or moving parts. 4) Before starting work, remove the leads from the negative (–) terminal first. 5) When raising a heavy component (heavier than 25 kg), use a hoist or crane. Before starting work, check that the slings (wire ropes, chains, and hooks) are free from damage. Always use slings which have ample capacity and install them to proper places. Operate the hoist or crane slowly to prevent the component from hitting any other part. Do not work with any part still raised by the hoist or crane. 6) When removing a cover which is under internal pressure or under pressure from a spring, always leave 2 bolts in diagonal positions. Loosen those bolts gradually and alternately to release the pressure, and then remove the cover. 7) When removing components, be careful not to break or damage the electrical wiring. Damaged wiring may cause electrical fires. 8) When removing piping, stop the fuel or oil from spilling out. If any fuel or oil drips onto the floor, wipe it up immediately. Fuel or oil on the floor can cause you to slip and can even start fires. 9) As a general rule, do not use gasoline to wash parts. Do not use it to clean electrical parts, in particular. 10) Be sure to assemble all parts again in their original places. Replace any damaged parts and parts which must not be reused with new parts. When installing hoses and wires, be sure that they will not be damaged by contact with other parts when the machine is operated. 11) When installing high pressure hoses, make sure that they are not twisted. Damaged tubes are dangerous, so be extremely careful when installing tubes for high pressure circuits. In addition, check that connecting parts are correctly installed. 12) When assembling or installing parts, always tighten them to the specified torques. When installing protective parts such as guards, or parts which vibrate violently or rotate at high speed, be particularly careful to check that they are installed correctly. 13) When aligning 2 holes, never insert your fingers or hand. Be careful not to get your fingers caught in a hole. 14) When measuring hydraulic pressure, check that the measuring tools are correctly assembled. 15) Take care when removing or installing the tracks of track-type machines. When removing the track, the track separates suddenly, so never let anyone stand at either end of the track. 16) If the engine is operated for a long time in a place which is not ventilated well, you may suffer from gas poisoning. Accordingly, open the windows and doors to ventilate well.

Precautions when carrying out any operation When carrying out removal or installation (disassembly or assembly) of units, be sure to follow the general precautions given below when carrying out the operation. 1.
Precautions when carrying out removal work
•
If the coolant contains antifreeze, dispose of it correctly.
•
After disconnecting hoses or tubes, cover them or fit plugs to prevent dirt or dust from entering.
•
When draining oil, prepare a container of adequate size to catch the oil.
•
Confirm the match marks showing the installation position, and make match marks in the necessary places before removal to prevent any mistake when assembling.
•
To prevent any excessive force from being applied to the wiring, always hold the connectors when disconnecting the connectors. Do not pull the wires.
•
Fit wires and hoses with tags to show their installation position to prevent any mistake when installing.
•
Check the number and thickness of the shims, and keep in a safe place.
•
When raising components, be sure to use lifting equipment of ample strength.
•
When using forcing screws to remove any components, tighten the forcing screws uniformly in turn.
•
Before removing any unit, clean the surrounding area and fit a cover to prevent any dust or dirt from entering after removal.
•
After disconnecting any piping during disassembly operations make sure to use the correct plugs and seals when connecting the piping again.
2.
Precautions when carrying out installation work
•
Tighten all bolts and nuts (sleeve nuts) to the specified torque.
•
Install the hoses without twisting or interference and fix them with intermediate clamps, if there are any.
•
Replace all gaskets, O-rings, cotter pins, and lock plates with new parts.
•
Bend the cotter pins and lock plates securely.
•
When coating with adhesive, clean the part and remove all oil and grease, then coat the threaded portion with 2 – 3 drops of adhesive.
•
When coating with gasket sealant, clean the surface and remove all oil and grease, check that there is no dirt or damage, then coat uniformly with gasket sealant.
•
Clean all parts, and correct any damage, dents, burrs, or rust.
•
Coat rotating parts and sliding parts with engine oil.
•
When press fitting parts, coat the surface with anti-friction compound (LM-P).
•
After fitting snap rings, check that the snap ring is fitted securely in the ring groove.
•
When connecting wiring connectors, clean the connector to remove all oil, dirt, or water, then connect securely.
•
When using eyebolts, check that there is no deformation or deterioration, screw them in fully, and align the direction of the hook.
•
When tightening split flanges, tighten uniformly in turn to prevent excessive tightening on one side. When operating the hydraulic cylinders for the first time after reassembling cylinders, pumps and other hydraulic equipment removed for repair, always bleed the air as follows: 1) Start the engine and run at low idle. 2) Operate the work equipment control lever to operate the hydraulic cylinder 4 - 5 times, stopping the cylinder 100 mm from the end of its stroke. 3) Next, operate the hydraulic cylinder 3 - 4 times to the end of its stroke. 4) After doing this, run the engine at normal speed. When using the machine for the first time after repair or long storage, follow the same procedure.

When carrying out the operation with 2 or more workers, keep strictly to the agreed signals, and do not allow any unauthorized person to come near. If the radiator cap is removed when the engine is hot, hot coolant may spurt out and cause burns, so wait for the engine to cool down before starting troubleshooting. Be extremely careful not to touch any hot parts or to get caught in any rotating parts. When disconnecting wiring, always disconnect the negative (–) terminal of the battery first. When removing the plug or cap from a location which is under pressure from oil, water, or air, always release the internal pressure first. When installing measuring equipment, be sure to connect it properly. The aim of troubleshooting is to pinpoint the basic cause of the failure, to carry out repairs swiftly, and to prevent reoccurrence of the failure. When carrying out troubleshooting, and important point is of course to understand the structure and function. However, a short cut to effective troubleshooting is to ask the operator various questions to form some idea of possible causes of the failure that would produce the reported symptoms. 1.
When carrying out troubleshooting, do not hurry to disassemble the components. If components are disassembled immediately any failure occurs: • Parts that have no connection with the failure or other unnecessary parts will be disassembled. • It will become impossible to find the cause of the failure.
It will also cause a waste of man hours, parts, or oil or grease, and at the same time, will also lose the confidence of the user or operator. For this reason, when carrying out troubleshooting, it is necessary to carry out thorough prior investigation and to carry out troubleshooting in accordance with the fixed procedure. 2.
Points to ask user or operator: 1) Have any other problems occurred apart from the problem that has been reported? 2) Was there anything strange about the machine before the failure occurred? 3) Did the failure occur suddenly, or were there problems with the machine condition before this? 4) Under what conditions did the failure occur? 5) Had any repairs been carried out before the failure? When were these repairs carried out? 6) Has the same kind of failure occurred before?

3.
Check before troubleshooting 1) Check the oil level 2) Check for any external leakage of oil from the piping or hydraulic equipment 3) Other maintenance items can be checked externally, so check any item that is considered to be necessary.
4.
Confirming failure • Confirm the extent of the failure yourself, and judge whether to handle it as a real failure or as a problem with the method of operation etc. When operating the machine to re-enact the troubleshooting symptoms, do not carry out any investigation or measurement that may make the problem worse.
5.
Troubleshooting • Use the results of the investigation and inspection in items 2-4 to narrow down the causes of failure, then use the troubleshooting flowchart to locate the position of the failure exactly. The basic procedure for troubleshooting is as follows. 1) Start from the simple points. 2) Start from the most likely points. 3) Investigate other related parts or information.
6.
Measures to remove the root cause of any failure Even if the failure is repaired, if the root cause of the failure is not repaired, the same failure will occur again. To prevent this, always investigate why the problem occurred. Then, remove the root cause.

Handling of electric equipment and hydraulic components Points to remember when handling electric equipment 1.
Handling wiring harnesses and connectors Wiring harnesses consist of wiring connecting one component to another component, connectors used for connecting and disconnecting one wire from another wire, and protectors or tubes used for protecting the wiring. Compared with other electrical components fitted in boxes or cases, wiring harnesses are more likely to be affected by the direct effects of rain, water, heat, or vibration. Furthermore, during inspection and repair operations, they are frequently removed and installed again, so they are likely to suffer deformation or damage. For this reason, it is necessary to be extremely careful when handling wiring harnesses.
2.
Main failures occurring in wiring harness
1) Defective contact of connectors (defective contact between male and female) Problems with defective contact are likely to occur because the male connector is not properly inserted into the female connector, or because one or both of the connectors is deformed or the position is not correctly aligned, or because there is corrosion or oxidization of the contact surfaces.
2) Defective criming or soldering of connectors The pins of the male and female connectors are in contact at the crimped terminal or soldered portion, but if there is excessive force brought to bear on the wiring, the plating at the joint will peel and cause improper connection or breakage.
3) Disconnections in wiring If the wiring is held and the connectors are pulled apart, or components are lifted with a crane with the wiring still connected, or a heavy object hits the wiring, the crimping of the connector may separate, or the soldering may be damaged, or the wiring may be broken.

Part II
4) High-pressure water entering connector The connector is designed to make it difficult for water to enter (drip-proof structure), but if highpressure water is sprayed directly on the connector, water may enter the connector, depending on the direction of the water jet. Accordingly, take care not to splash water over the connector. The connector is designed to prevent water from entering, but at the same time, if water does enter, it is difficult for it to be drained. Therefore, if water should get into the connector, the pins will be short-circuited by the water, so if any water gets in, immediately dry the connector or take other appropriate action before passing electricity through it. 5) Oil or dirt stuck to connector If oil or grease are stuck to the connector and an oil film is formed on the mating surface between the male and female pins, the oil will not let the electricity pass, so there will be defective contact. If there is oil or grease stuck to the connector, wipe it off with a dry cloth or blow it dry with compressed air and spray it with a contact restorer. When wiping the mating portion of the connector, be careful not to use excessive force or deform the pins. If there is oil or water in the compressed air, the contacts will become even dirtier, so remove the oil and water from the compressed air completely before cleaning with compressed air. 3.
Disconnecting connectors 1)
When disconnecting the connectors, hold the connectors. For connectors held by a screw, loosen the screw fully, then hold the male and female connectors in each hand and pull apart. For connectors which have a lock stopper, press down the stopper with your thumb and pull the connectors apart. Never pull with one hand.
2) •
76
When removing from clips Both of the connector and clip have stoppers, which are engaged with each other when the connector is installed.
PC4000-6D S/N 08199 and up
Part II
40 Troubleshooting
•
When removing a connector from a clip, pull the connector in a parallel direction to the clip for removing stoppers. If the connector is twisted up and down or to the left or right, the housing may break.
3)
Action to take after removing connectors After removing any connector, cover it with a vinyl bag to prevent any dust, dirt, oil, or water from getting in the connector portion. If the machine is left disassembled for a long time, it is particularly easy for improper contact to occur, so always cover the connector.
Points to remember when handling hydraulic equipment With the increase in pressure and precision of hydraulic equipment, the most common cause of failure is dirt (foreign material) in the hydraulic circuit. When adding hydraulic oil, or when disassembling or assembling hydraulic equipment, it is necessary to be particularly careful. 1.
Be careful of the operating environment Avoid adding hydraulic oil, replacing filters, or repairing the machine in rain or high winds, or places where there is a lot of dust.
2.
Disassembly and maintenance work in the field If disassembly or maintenance work is carried out on hydraulic equipment in the field, there is danger of dust entering the equipment. It is also difficult to check the performance after repairs, so it is desirable to use unit exchange. Disassembly and maintenance of hydraulic equipment should be carried out in a specially prepared dustproof workshop, and the performance should be checked with special test equipment.

3.
Part II
Sealing openings After any piping or equipment is removed, the openings should be sealed with caps, tapes, or vinyl bags to prevent any dirt or dust from entering. If the opening is left open or is blocked with a rag, there is danger of dirt entering or of the surrounding area being made dirty by leaking oil so never do this. Do not simply drain oil out onto the ground, but collect it and ask the customer to dispose of it, or take it back with you for disposal.
4.
Do not let any dirt or dust get in during refilling operations Be careful not to let any dirt or dust get in when refilling with hydraulic oil. Always keep the oil filler and the area around it clean, and also use clean pumps and oil containers. If an oil cleaning device is used, it is possible to filter out the dirt that has collected during storage, so this is an even more effective method.
5.
Change hydraulic oil when the temperature is high When hydraulic oil or other oil is warm, it flows easily. In addition, the sludge can also be drained out easily from the circuit together with the oil, so it is best to change the oil when it is still warm. When changing the oil, as much as possible of the old hydraulic oil must be drained out. (Drain the oil from the hydraulic tank; also drain the oil from the filter and from the drain plug in the circuit.) If any old oil is left, the contaminants and sludge in it will mix with the new oil and will shorten the life of the hydraulic oil.
6.
Flushing operations After disassembling and assembling the equipment, or changing the oil, use flushing oil to remove the contaminants, sludge, and old oil from the hydraulic circuit. Normally, flushing is carried out twice: primary flushing is carried out with flushing oil, and secondary flushing is carried out with the specified hydraulic oil.
7.
Cleaning operations After repairing the hydraulic equipment (pump, control valve etc.) or when running the machine, carry out oil cleaning to remove the sludge or contaminants in the hydraulic oil circuit. The oil cleaning equipment is used to remove the ultra fine (about 3 µ) particles that the filter built in the hydraulic equipment cannot remove, so it is an extremely effective device.

A)
Air bleeding from the hydraulic pumps The air bleeding procedures for the hydraulic pumps are described in the following manuals. Refer to these manuals as necessary.
•
Operation & Maintenance Manual, section HYDRAULIC SYSTEM - CHANGE OIL, REPLACE SUCTION STRAINERS AND PULSATION DAMPER
•
PARTS & SERVICE NEWS AH01513 (latest version) Precautions for air bleeding from the hydraulic pumps Before starting the air bleeding work explained above, run the engine at low idle for 10 minutes.
B)
Air bleeding from hydraulic cylinders 1)
Start the engine and keep it running at low idle for 5 minutes.
2)
Running the engine at high idle raise and lower the respective cylinders 12 to 15 times. Be careful not to apply the relief pressure, stopping the piston rod approx. 100 mm before its stroke end.
3)
Apply the relief pressure smoothly by extending the piston rod to its stroke end and with the engine running at high idle.
4)
For bleeding air from the arm cylinder and bucket cylinder, follow the same steps explained in items 2) and 3) above.

Cylinder bypass test The cylinder bypass test can be performed in order to check if a hydraulic cylinder has an internal leakage. A cylinder with an internal leakage generates a higher temperature (at operating temperature of the machine) than a hydraulic cylinder which has no internal leakage. For a bypass test at mining machines always use an infrared thermometer, refer to section Fundamental requirements for troubleshooting in this manual. Refer to chapter Safety and observe all safety notes for the following procedure.
Procedure 1. Before starting the bypass test, always make sure that the hydraulic circuit which is to be tested, has reached the operating temperature (T3). 2. Bring the concerning cylinders in their end position → rod end completely moved in or out. 3. Keep up the system pressure in the concerning hydraulic circuit for approx. 10 minutes. 4. During these 10 minutes, measure the cylinder temperature in the piston area of both cylinders, using an infrared thermometer. If any cylinder seal package is leaking, hydraulic oil is now pressed through this leakage, which causes the temperature to increase (90°C and higher) within a few minutes.
Case 1 Seal package is leaking in 1 cylinder only
Seal package is leaking in both cylinders
Defective cylinder: Temperature increase during the test, increased temperature approx. 90°C
Both defective clinders: Temperature increase during the test, increased temperature approx. 90°C
Proper clinder: No temperature increase during the test, normal temperature approx. 70°C

Adhesive lubricants for the Slew Ring Gear
PURPOSE:
Revision

FAILURE CODE:
2500Z9
DESCRIPTION: The transmission of a torque from the slew pinion to the toothing of the slew ring causes the slewing of the superstructure. The existing extreme force in this section requires the separating of the engaged gears by means of grease film, to ensure a proper damping of shocks and to prevent metallic abrasion. Adhesive lubricants may be applied by means of an automatic slew ring gear lubrication system or manually by a spatula, brush, spray tin. Automatically tooth lubrication systems provides the upper most protection because of the continuously uninterrupted lubrication, permanent checks are not required.
AH00519c
Page 2 of 4
)
• Independent of the lubricant and lubrication system, the toothing should be visually checked approx. every 500 working hours. If the check is not possible because of applied lubricant, the toothing has to be cleaned at several points equally distributed on the circumference of the slew ring. In case of wear or damages, Dept. 8151 has to be informed to discuss suitable remedies.
ã
• These adhesive lubricants provide totally different features compared to the Bearing greases / MPG (e.g. used in the central lubrication system). Hence, those lubricants must not replace against each other or mixed. Example:
This may happen when grease (1) pressed out of the upper sealing system of the races forms too big collar at
the slew ring and penetrates into the toothing (2). This eventuality must be avoided by removing the excess grease.
AH00519c
Page 3 of 4 The following table includes several adhesive lubricants providing excellent results on several machines under different working conditions. The use of other lubricants is not recommended before consultation of Dept. 8151. Note: Use these Greases for Swing Circle open Gear Lubrication only Ambient Temperature °C ⇒ °F ⇒ Supplier

DESCRIPTION:
Diesel engines are mounted on elastic elements. With increase of life the flexible mountings will show setting effects. 1.
Inspection intervals
• Damages to the engine might arise if the bolts of the flexible mountings are not tightened correctly.
1.1 Therefore check bolts after the following intervals: • Prior to putting the machine into operation or after replacement of the flexible mountings • after the first 250 operating hours • every 1000 operating hours or every 6 month latest
1.2 The elastic engine suspension must be checked (visual check): • Every 6 month or every 1000 operation hours (check the flexible mountings for damage). 1.3
Check the fatigue of the rubber elements according to the appendix (pages 5 to 9) once a year and give the records to our service department. Take a calliper.
AH01521a
Page 2 of 9
2.
Kinds of mounts
There are two types of mounts at each location: Type A: Flexible engine mountings Type B: Flexible engine mountings with self locking nut item (3) for limiting of the flexible distance.
3.
Control measures (see also in your Operation and Maintenance Manual) (Caterpillar-Engine fig.1; Cummins/Komastu - Engine fig.2) • All tests during motor stop!
The bolts of the flexible engine mountings have to be checked as follows: 1. Tighten the bolt (2) to 880 Nm (649 lbf ft). 2. Position the nut (3) so it just touches the steel plate of the rubber mount item (6). Tighten the nut an additional ¼ turn (90°).
F
Over tightening of this nut will result in removing the required elasticity of the rubber mounts and may cause engine failure.
3. Only by Cummins Engines Check distance „C“ between torque support and stop bolt(4). With setting of the flexible engine mountings the distance „C“ increases and must be readjusted. To do this, loosen lock nut (7) and tighten stop bolt (4) until the correct distance „C“ is obtained. Tighten lock nut (7) and recheck distance (C). 4. Check all rubber metal bars (1) and all strips (6) for damage.
F
• All rubber metal bars(1), all strips(6) and all cup springs(5) should be replaced during engine overhaul.

Period of the first 10.000 h: 2. Period more than 10.000 h:
every 5.000 working hours; every 2.500 working hours.
After finishing the measurements, record the values obtained in a tabular form. The diagram shows the principle of bearing wear progression. If the “increased wear” situation is reached, prepare the changing of the swing circle.
)
• We recommend to turn the swing circle (180°) after 20 000 working hours.

1. Park the machine on level ground. 2. Slew the attachment to the normal working position (idler wheel in front). 3. Remove cover as shown in the photos (Illust. 7 and 8). 4. Clean the center slew gear tooth and the contact point on the superstructure. 5. Install the dial gauge* as shown in the photos. 6. Turn the swing brake switch in the on position. 7. Straighten the attachment fully (lmax) and raise the shovel approx. A=3 m over the ground (Illust. 1, 3 or 5). 8. Set measuring instrument (dial gauge*) to zero.
ã
• Make sure the area below and around the excavator is clear of all persons before you start operating.
9. Move the attachment in the shown position (Illust. 2, 4 or 6). Lower the attachment until the track lift off the ground up to the sprocket (B).
)
• Use for all measurements the same distances “A” and “B”.
10. Move the attachment in the normal parking position. 11. Read measurement “M 1” (out of the memory) and record in the table (page 4). 12. Repeat the measuring procedure at the same point for a 2nd value (M 2). 13. Remove the dial gauge, swing the superstructure 180 degrease and repeat the measuring procedure two times. * We recommend to use a digital dial gauge with min. / max. measuring value memory (Part No. 794 537 73).

Track group – wear measurement
PURPOSE:
Increasing the service life and avoiding unforeseen standstill
APPLICATION:
H 185 to PC8000
FAILURE CODE:
752DCA
DESCRIPTION: The professional and regular inspection increases the service life of the track group and can avoid early and very expensive repairs, including unforeseen standstill of the machine. It is recommended to perform the inspections every 3 month or 1500 working hours according to the description and to fill in the measured values to the table on page 06.
The measurements are described in detail and illustrated on pages 02 - 05.
To prevent unnecessary problems and standstills and to assure fast help when wear limits are reached, it is recommended to send the filled-in tables in the mentioned intervals to Komatsu Mining Germany, Service Department 8151.

Chain elongation / measured over three track pads (4 pins) This wear check has to be carried out in 4 equally distributed areas of the track chain (L1 to L4 - l.h. and R1 to R4 - r.h.). • Turn superstructure 90° to the travel direction. • Retract attachment and lower bucket on the ground until the chain has no longer contact with the ground (see illustration). • Turn sprocket until the first measuring area (L1) is located at the deepest point of sag (“T“). (To measure the areas L2-L4 turn the chain always forward until point “T“ is reached) To obtain a comparable measuring result, stop the main drive motor of short duration, so that the track tensioning system is released to 35 bar. For the track sag refer to page 02.
Place the points of the dividers into the centre bores of pins 1 and 4 of the measuring area L1 / R1, determine the distance and record in the table on page 06. Repeat measuring procedure at measuring areas L2 / R2 - L4 / R4.
AH02521
Page 4 of 6 Circular pitch (Sprocket / Track pad) For this inspection, the excavator has to be placed on an even surface, and only one chain has to be moved, like turning. • Diesel engine: Operate in low idle. • Electric motor: Operate joy-stick slightly. • Move l.h. track group forward (Sprocket rotation F = forward), until the contact area of the uppermost sprocket tooth (0) and the track-pad lug (0) is in the illustrated position, see ill. A, on page 05. • Measure gaps (X1) according to ill. A. Measure inside and outside of the sprocket between the sprocket teeth (7) and track-pad lug (7) at 3 points, equally distributed on the chain. • Record the values into table -circular pitch A- on page 06. • Repeat the measurements on the r.h. track group. • Move l.h. track group back (Sprocket rotation R = backwards), until the contact area of the lowest sprocket tooth (0) and the track-pad lug (0) is in the illustrated position, see ill. B, on page 05. • Measure gaps (X2) according to ill. B. Measure inside and outside of the sprocket between the sprocket teeth (7) and track-pad lug (7) at 3 points, equally distributed on the chain. • Record the values to the table -circular pitch B- on page 06. • Repeat the measurements at the r.h. track group.
F
• The minimum permissible X1/X2 dimension amounts 0.5mm. If this dimension is reached, an oversized sprocket has to be installed, to bring the X1/X2 dimension to the new condition. • If the dimension X becomes a negative amount (less than 0mm). the lugs of the track pads will be damaged so strongly, that a complete exchange of the track pads will be the required. Therefore, make sure that the X1/X2 dimension never falls below 0.5mm.
For the exchange of the oversize sprockets, refer to Service Bulletin AH00514.
Wear of track pads (Roller contact surface) • Stop the engine/motor and secure the machine against unintentional movement. • Mark 3 track pads of each track group (l.h. track group and r.h. track group) to make repeated measurements in the future comparable. • Take a ruler to measure the wear of the roller contact surface. The ruler needs an even contact surface, if not exist, prepare the track pad as necessary, see illust.. C, page 05. • Record the measuring results in the form sheet on page 06.

DESCRIPTION:
General In order to increase the lifetime of the parking brake discs the swing gear oil filling capacity should be reduced by approximately 20 liters. The new filling capacity is approx. 42 liters. The present oil level gauge on the gear can no longer be used for checking the oil level. There are two possibilities to modify the oil level checking system. For increasing the lifetime of the slew gear the sun gear shaft should be changed during the slew gear modification. Page 1. Modification Kits 2 2.

Page 25 of 25 5. Oil level checking procedure (engine at standstill) The design of the swing gear requires four or five locations for oil level checking. The correct oil level is below the upper planetary stage. To reach this level between the planetary gears it is necessary to find out at which of the four, five or six tubes the oil level gauge can be insert to the stop.
Proceed as follow: 1. Take out oil level gauge (19) from bracket (20). 2. Remove plug (18) from one tube (14) and insert gauge (19). If the gauge can not be moved in to the stop use the next tube (14). Repeat this procedure until the gauge can be inserted to the stop. 3. The oil level should be between the MIN and MAX marking on the gauge. Add oil if necessary. 4. Remove oil level gauge from the tube and insert into bracket (20). 5. Close the tubes with the plugs (18).
• Do not leave the gauge (19) in the tube (14). If the gauge is left in the tube the swing gear and the gauge will be damaged when the swing gear operates.

Installing the points
Preparation Prior to point replacement, make sure adapters are clean and free of damage. Carefully inspect adapters for excessive wear. If the nose is worn or if insufficient wear metal remains to see adapters through their work cycle, they should be replaced with new ones. Vertical locking pins: Locking pins may be reused provided they do not show signs of significant wear, damage or distortion. Points: If you are going to install new points, make sure the rubber lock is installed so the arrows embossed on the surface of the lock are pointing forward (toward the tip of the point).
Position the locking pin and drive it in.
Vertical locking pin
Point • •
Install the points onto the adapters. After positioning a point onto its adapter, drive in the vertical locking pin using an 4 kg (8lb) hammer. The rubber lock keeps the Posilok Pin securely in place.
Posilok Pin engages the lock.
Topside and forward •
Drive in the Posilok Pin until it engages the lock. When the Posilok Pin is correctly in place, the rubber lock fits into the slot of the Posilok Pin to secure it.

Adapter removal Prior to using an adapter tool be sure that the following safety precautions are followed at all times: • Always wear proper safety equipment including hardhat, gloves, safety glasses and steel-toed shoes. • Never exceed the lifting capacity of the tool. Lifting tool 122K (Part No. 793 503 73) rated capacity 270kg (600lb) - for the S145 tooth system. Lifting tool 112K (Part No. 793 504 73) rated capacity 230kg (500lb) - for the S130 tooth system. • Tool is intended for vertical lift only. • Always stand clear of the raised adapter. • Never allow anyone to work under the adapter until it is secured to the lip by the appropriate locking mechanism. • Always use the safety features (lock and safety pin) as indicated. Never use hand tools or other fastener to secure the sleeve. Never use anything other than the sleeve provided to support the adapter. • Replace the tool when it becomes visibly damaged or distorted. Do not attempt to repair a damaged tool.
• •
Position the bucket with the nose tilted slightly upward. Clean debris from adapter Sidewinder Pin head slot and remove cap from Sidewinder Pin head. (The fastening Sidewinder Pin may become frozen in the nose hole by cemented fines. In this event, use either a hammer and drift or a porta-power, applied directly against the end of the Sidewinder Pin sleeve, to force the Sidewinder Pin out. Use a striking plate, as needed, to avoid hammering the end of the Sidewinder Pin base. With body completely retracted, insert drift that fits inside hex recess and hammer Sidewinder Pin through nose hole. Alternately, drift can be placed against outer sleeve. Avoid hammering over hex recess and thereby peening over the edges of this recess.)

Page 12 of 18
Remove Wearcap: Slide wearcap out of adapter slots. Use appropriate lifting devices to support and remove wearcap. It may be necessary to place a pry bar between the adapter and the rear inside face of the wearcap to lift and free it from soil fines.
4.1.2 Installation
!
• Wearcap tabs, adapter tab slots, and lock recesses must be thoroughly cleaned. Inspect all components for damage. Replace any damaged parts.
•
Position Wearcap Lock First place the lock flat side down against the inside of the wearcap, adjacent to the lock opening. Slide it toward the wearcap lug. One of the lock shafts will enter the hole in the lug. Push the lock up tight against the lug. Then, using a drift placed in one of the lock pockets, tap the drift with a hammer to cause the lock to rotate halfway around, until the flat side of the lock is facing you and is lined up with the inside face of the wearcap.
•
Wearcap Installation Place the wearcap on the adapter. The tabs on the inside of the wearcap fit into the tab slots in the adapter.
•
Lock Wearcap Use an suitable tool and hammer to rotate the lock to the locked position. If lock resists rotation, this indicates more cleaning of the adapter slots is required. When flat is facing out, the lock is in a locked position.

The Shrouds Removal the shrouds
The Toplok shroud system is engineered to make change-out easy. Before following these simple steps shown to the Figures, it’s important to clean fines from pin area by tapping the shroud to loosen them, then scraping them using a chisel or needle gun (if fines are heavily packed). • •
Use a small bar with flat end (19 mm wide maximum) to retract the latch and lift the pin out. Pins can be reused if not worn below the locator flange and the insert latch rubber is fully bonded to the steel tip and fully seated in the pin body.
Place a pry bar or pinch bar behind the latch as shown, as a lever to compress it.
!
Lift out and remove the lock. Slide the shroud off the lip base.
• In severe applications assist removal by inserting a pry bar under the lock from the rear of the shroud and lifting up the latch end of the pin while prying as shown.
AH03510
Page 15 of 18
5.2 Installing the shroud 5.2.1 Prepare the surface In order to provide sufficient support for the boss as well as its pin, the mounting surface must: • Be relatively smooth and free of debris, weld spatter, and other irregularities. • Have a profile that produces a gap no greater than 3 mm or 1/16" at the boss weld. Any gap greater than 3 mm or 1/16" must be shimmed. Checking the Fit Pad Areas • • • •
The fit pad surface (1) & (2) should be perpendicular to each other. Make sure 70% of the fit pad surfaces (1) & (2) are in contact with the gauge. After achieving this, the fit pad surface (3) should be checked. Use a straight edge to help check the surface consistency.

5.2.2 Position the bosses Checking the Boss Position To insure the boss is located correctly, the gap between the gauge and the boss rails should not exceed 1mm/.04in. If the gap exceeds 1mm/.04in.,the boss has to be removed and a new boss installed (see below). The back of the boss should line up with the back of the gauge rail. If the boss does not line up with the back of the gauge rail, then two repair options are possible: • (A) If the gap does not exceed 1.5mm/.06in., build up the back of the boss; or • (B) Weld build the leading edge fit pad (2). This may result in the ramp fit pad (3) also requiring weld build up.
Weld Rebuilding Fit Pads When weld rebuilding fit pads ensure the weld surface is clean and free of any contamination that might prevent a good weld. Follow the preheat, interpass and post heat guidelines below. Summary of Welding Specifications • Electrodes: E7016 or E7018 low hydrogen (keep dry!) • Wires: E70T-5, E71T-1, or E70T-1 with CO 2 gas. • Preheat: 200°F/95°C (350-400°F/175-205°C if air temperature is 40°F/5°C or lower.) • Interpass: Maintain interpass temperature less than 500°F/260°C. • Postheat: If air temperature is 40°F or lower, postheat 350-400°F, then let air cool. • Remove slag after each pass and peen each bead. New Boss installation • Set the boss onto the gauge rails and locate the back of the boss with the back of the gauge rails. If no gauge is available, use a new shroud to locate the boss. • Move the gauge onto the lip, making sure the gauge is centered between the nose bases and the gauge is in contact with fit pad surfaces (1) & (2). • Practice has shown, that the boss will suck down 1/16" during welding. To equalize this use a 1/16" shim under the boss, even if there is no gap between the fit pad (1) and the boss. This will ensure the boss height is correct after welding. • If there is a gap between the fit pad surface (1) and the boss, use a thicker shim accordingly.

Introduction Part number Precautions for Controller Replacement Appendix VHMS initial setting check sheet
1. Introduction PC4000 are equipped with a VHMS controller as part of their standard specifications. The VHMS controller is a device to control the CGC display and to record the history of machine operation. The VHMS controller is constantly powered direct by a battery and its function is to compile and record the day's operation in the VHMS memory, after the engine is switched off, while checking data consistency with the record up to the previous day. This work takes a certain amount of time, i.e. approx. 10 seconds. For this reason, cautions have to be taken in advance, when disconnecting the power to the VHMS. Such disconnection usually takes place with machines equipped with a battery isolator and a turbo-timer, when switching off the engine for emergency, right after the turbo timer has been set in operation, or when the battery terminal is disconnected immediately after switching off the starting switch, say for welding. In such case, the compilation and write-in work in the VHMS memory is interrupted, resulting in the controller program being damaged and the initial screen remaining in the CGC display unchanged. Hence be sure to provide an interval of more than 3 minutes after the engine is switched off and before disconnecting all the electric circuits. This Parts and Service News describes the procedures for you to follow when replacing the existing VHMS controller with a new one.

Precautions for Controller Replacement
3.1 Before starting with the replacement A. Download the VHMS data, if possible. First download the data on failure history in the existing VHMS controller that have been stored up to that moment, since they will likely be lost by the replacement. Next send them to WebCare. B
Disconnect the normal VHMS power source.
i)
Terminate the normal power supply by turning off the ignition key.
ii)
Maintain constant power supply for the controller at least for more than two minutes.
iii)
Then terminate constant power supply for the controller by disconnecting the power source.
3.2 Procedures for replacement and setting of VHMS system and actions after replacement A. Precautions for replacement: Replace the existing VHMS system with new one, taking care that no excessive force or shock is applied to the main body, the harness, etc. Relative to the VHMS connectors, disconnect CN1 first and connect it last, since it serves as a power supply cable, too.

Maintenance Monitor (No. 4.5 – 4.5.1) Maintenance Acknowledgement
Maintenance confirmation through Service Personnel Maintenance indicated with yellow or red background color should be confirmed through Service Personnel in the Service Menu subsequent to the execution of the maintenance. With the confirmation the actual value maintenance number is increased by 1. Thus, the length of the maintenance cycle is added to the display value and the gray color will appear in the maintenance display. The button in the Service Menu used for maintenance confirmation then turns gray instead of yellow and is then without any function. The confirmation of the maintenance is then stored. Example: 250h Maintenance is required (yellow), service meter reading is 252 Hours.
When you select the yellow button, again, it changes to blue and starts blinking. MAINTENANCE MONITOR

Emphasize the importance of expelling the accumulate gases from the counterweight chambers before welding
APPLICATION:
H 255; PC3000; PC5500(SN15011 and up); PC4000; PC8000(SN12037 and up)
FAILURE CODE:
4621Z9
DESCRIPTION:
ã
• Avoid injury or death! • Do not perform welding operation before expelling the accumulated gases from the counterweight chambers! • The gases may explode!
The welded counterweights are filled with a mixture of iron ore and breech blocks. They are not fully filled. It is possible that in the separate chambers explosive gases have collected. There is a risk of explosion during welding, grinding, cutting and drilling without coolant.
The following outlines the proper gas expelling procedure from counterweight (Illustrations 1 and 2) 1. Counterweights with a thread connection point(1): Connect a hose to this point and blow compressed air toward the inside. At these counterweights all chambers are connected to each other. 2. Counterweights without thread connection point: Make the holes (2) larger by means of a 10 mm drill. Blow out carefully all chambers separately through the holes (2).

Dual cone seal ring mounting
PURPOSE:
Mounting hints
APPLICATION:
all types
FAILURE CODE:
3047AA
DESCRIPTION: Leaky dual cone seal rings must be replaced, in order to prevent damages through "dry running". Dual cone seals have also to be replaced in case of component repairs. Dual cone seals are precision parts made from chilled cast iron. Therefore, sharp knocks and blows should be avoided. The correct way to install dual cone seals is as follows: • Only remove the seal (1) from its original wrapping just before installing. This protects the super - finished seal faces (2) from damage and contamination. • Seal housing (3) must be free of dirt and machining residues; all edges in the housing bore must be rounded. • The illustration shows the preloaded seal (1). • Install the face seal by means of the assembly tool (4). Pressure is applied directly via the O-ring (5). • For easier assembly, moisten the housing bore and O-rings with spirit (no oil or grease!). • Order number for assembly tool (4), refer to the table on page 2. For the machining dimensions of the assembly tool, refer to the illustration and Fig. on page 3. • The illustration shows the dual cone seal (1) before mounting it with tool (4) into housing (3).
AH05511
Page 2 of 4 • Press the seal ring (1) with the special tool like a push button into the housing (3). Take care that afterwards the housing surface (6) lies parallel to the seal face (2). The O-ring (1) must not sit wave-like in the housing bore or bulge partially looped out of the bore. C = correct W = wrong
• Before the seal rings (1) are clamped to the installation dimensions, apply a thin grease or oil film to the seal faces (2), preferably with a soaked chamois leather cloth. Fig. 1 2 3 4 5 6

Page 3 of 4 Assembly tool (locally made) The assembly tool consists of two half-shells that are closed around the seal ring. The two halves are joined by a hinge. Step (d) grips between the O-ring (5) and the land of the seal ring. The pressure required to insert the seal is then applied directly via the O-ring (5). Measure dimension "b" at the dual cone seal. Determine the machining dimensions "a", "b", "c" and "d" according to this measured dimension in the chart. The dimension "X" can be chosen freely.

SUBJECT:
Automatic lubrication system - Vent valve (PN 769 879 73)
PURPOSE:
Hints for trouble shooting
APPLICATION:
All types with “Lincoln” Lubrication System
FAILURE CODE:
8D00ME
DESCRIPTION:
Manual actuation (Vent valve: PN 769 879 73)
FUNCTION: The solenoid gets energized when the lubrication starts. The connection from A to B gets closed, thus a pressure build-up is possible. The solenoid gets de-energized, as soon as the lubrication cycle is finished. This causes opening of the connection A to B, thus the supply line to the lubricant barrel is open. The lubricant flows from A to B. TASK (Refer to illustration next page): By the function of the vent valve (7) the lubricant supply line gets pressure released, after the lubrication cycle is finished. The injector pistons can move into their initial position.
AH05546
Page 2 of 2
Troubleshooting: The solenoid valve (7) sometimes is blocked by dirt and causing that the pumping pressure will be not built correctly due to bypassed pressure back to grease barrel. On the monitor in the operators cab any failure in lubrication system will be indicated.
Manual actuation
To make easy troubleshooting the 2/2 – Directional valve (7) is equipped with the possibility of manual actuation. The valve had a push button on the top to verify whether the electric problem or the vent valve itself causing the lubrication pressure bypassed. For manual actuating of the valve (7) push down the pin on top of the valve e.g. with a screwdriver.

DESCRIPTION: To avoid damages to the hydraulic system caused by air in the cylinders, a bleeding procedure has to be carried out after each opening or cylinder exchange. • Read the safety instruction in the Operation and Maintenance Manual carefully, before starting any work on the excavator.
1. Standard procedure for bleeding of hydraulic cylinder 1. Run the engine at low idle. PC5500 and PC8000: Start for the bleeding procedure only one engine. Electric driven excavators: Set the service switch S155 (X2 – main board) to position “2” for “QMIN” control of the main pumps. 2. Extend and retract each cylinder 4 or 5 times without going to the end of its stroke (stop approx. 100 mm before the end of the stroke). At first there can be a large amount of air inside the cylinders, so the cylinder may not move for the first ten seconds. In such cases, do not operate the joy stick to the end of its travel. Be carefully! 3. Keep the engine running at low idle/or QMIN* and operate each cylinder from a point 100 mm from the end of its stroke slowly (take at least 10 seconds) to the end of its stroke (fully extended) and hold the work equipment joy stick at the full stroke position for 3 minutes.

Next run the engine at high idle/or QMAX* and operate each cylinder from a point 100 mm from the end of its stroke slowly (take at least 10 seconds) to the end of its stroke (fully extended) and hold the work equipment joy stick at the full stroke position for 1 minutes. 5. Repeat steps 2 – 4 if necessary. 6. Make sure that the switch S155 is set to the “0” position as soon as the bleeding procedure of the hydraulic cylinders is finished.* * Electric driven excavator
