Before cleaning, completely regenerate the particle filter (operate the wheel loader for at least 10 minutes at the maximum possible engine load to burn off any soot sediment on the filter surface). Make sure that: – The machine is in maintenance position 1. – The engine compartment hood is open. – You have a suitable extraction system or industrial vacuum cleaner.
Compressed air cleaning
Procedure Caution Running at full load makes the filter housing very hot! ! When removing and cleaning it, always wear gloves, a dust mask and goggles. • Remove the filter module by releasing the V clips. • Clean the inlet side of the filter with compressed air and a vacuum cleaning system. Caution Protect the filter module from external contamination. - Never clean the filter module with steam or cleaning agents. - Use non-oiled compressed air for cleaning. • Clean the outlet side of the filter with compressed air and a vacuum cleaning system. Aim the air jet at each channel of the outlet side, until you cannot see any more particles. • Install the filter module again.
LBH/Version 01/10.2006/en/hd/22/02/2007
Note If the machine has been idling too long to regenerate the particle filter, the filter must be burned out. ! Put it in a furnace for at least 5 hours at 680 °C or use a hot air blower.

All year round, the coolant must contain at least 50% by volume of concentrated antifreeze, but not more than 60% by volume. This protects against freezing down to around -37 °C. Make sure that: – The machine is in maintenance position 1. – You have the optical density tester kit or antifreeze tester ready. Checking the antifreeze concentration
• See the coolant temperature on the display unit. The coolant temperature should be in the bottom third of the display. • Carefully open the sealing cap on the filler neck 1. • Take a sample of the coolant and check the antifreeze concentration using the test tool. • If the antifreeze concentration is too low: Refill with pure antifreeze until the required value is attained. See the section on correcting the antifreeze concentration.

This gives you the topping up quantity of pure antifreeze and corrosion protection agent 1 (7.6 litres in this example) to be added in order to achieve protection down to -37 °C. • To restore the correct mixing ratio, you must drain off at least the previously calculated quantity (the top-up quantity) from the cooling system. • Top up with the correct quantity of pure antifreeze and corrosion protection agent. • The coolant previously drained off can be used if necessary to restore the required coolant level. Using anti-corrosion agent without antifreeze In exceptional cases and when outside temperatures never fall below freezing, such as tropical zones, where it is demonstrable that no approved antifreeze and corrosion protection agent is available, corrosion inhibitors may be used. The coolant must be changed once a year. The mixing ratio must consist of 7.5% corrosion inhibitor and 92.5% water. The Gefo 2710 refractometer is recommended for testing.

Checking the indicator beads in the dryer-collector unit The dryer-collector unit is located on the right under the cooling system hood.
Sight glass in the dryer-collector unit • Check the orange bead 2 (moisture indicator). • If the orange bead 2 has turned transparent: There is moisture in the refrigerant circuit. You must replace the dryercollector and the compressor oil and refill the system. • The white bead 1 shows the filling level of R134a refrigerant in the circuit and acts as an indicator during initial filling. The white bead 1 must be at the top of the sight glass. The filling level can vary due to temperature fluctuations. It also sinks in time due to natural leakage. This does not impair operation. If the cooling performance deteriorates, one of the causes can be a low refrigerant level. In normal circumstances, one filling lasts for three to five years.

Checking the pressure relief and replenishing valve of the variable displacement pump
LBH/Version 01/10.2006/en/hd/22/02/2007
The pressure relief and replenishing valves protect the variable displacement pump from pressure peaks. These can occur when braking the machine. When a pressure peak occurs, oil flows from the high pressure side via the pressure relief and replenishing valve to the low pressure side in a closed circuit. Procedure To attain the set value for the pressure relief and replenishing valves, the pressure cut-off must be set to a higher value. • Screw in the adjusting screw 1 on the pressure cut-off by one turn. • Connect a manometer (600 bar) to the test connections MA and MB. • Use SCULI to set the Inch pedal - function OFF variable to 1 Æ the inching function is disabled.

Checking the engine output Before you check the power of the engine, you must carry out the following tasks: – Tasks in maintenance schedule (air filter, fuel filter etc.) – Check the operating pressures according to the adjustment checklist – The machine must be at operating temperature. At maximum engine power consumption, the variable displacement motor power limiting control is activated. It regulates the pivot angle of the motors so that the engine runs at rated speed. This results in a set high pressure in the closed circuit. – If the high pressure is is above the set value, the engine power is good. – If the high pressure is is below the set value, the engine power is poor. If the engine speed reaches the set value, power limiting control is working correctly. Procedure

Converting the hydraulic system from petroleum to environmentally compatible hydraulic fluids For the operation of LIEBHERR earth moving machines with environmentally compatible hydraulic fluids we recommend PANOLIN HLP SYNTH 46. Machines filled at factory with environmentally compatible hydraulic fluids have an appropriate sign (CAUTION) attached to the driver's cab and hydraulic tank. Procedure for conversion: Caution Beware of damaging the machine's hydraulic system. Mixing environmentally harmless hydraulic fluids with mineral oils produces a vigorous reaction that can damage the hydraulic system.
! Do not mix environmentally harmless hydraulic fluids with mineral oil. • If you intend to convert the machine to environmentally-compatible hydraulic fluid, you must first consult LIEBHERR CUSTOMER SERVICE. • Ask LIEBHERR for the instruction sheet and conversion guidelines and be sure to follow them.
3.7.1 Specification
Diesel fuels The diesel fuels must comply with the minimum requirements of the fuel specifications prescribed as follows. Authorised fuel specifications: – DIN EN 590 – ASTM D 975 (89a) 1D and 2D Further fuel specifications only upon consultation with the Diesel Engine Development Department, LIEBHERR Machines Bulle S.A.
Sulphur content in the diesel fuel
For worldwide markets except the USA: In DIN EN 590 the maximum sulphur content is 50 mg/kg = max. 0.005 % by weight. For the USA: In ASTM D 975 (89a) 1D and 2D, the maximum sulphur content is 10 ppm.
The diesel fuel lubricating proficiency must be a max. 460 µm in accordance with the HFRR (60) test. For diesel fuels featuring a sulphur content above / more than 0.5 weight%, the oil-change intervals are to be halved.

Maintenance Lubricants and fuels
Note In some cases, approval may be given, depending on the quality of the diesel engine lubricating oil. ! Fuel standard ASTM D 975 does not stipulate that fuels must pass a fuellubricity test. A written confirmation of the fuel supplier must be requested. The additives should be added by the supplier in his capacity as agent responsible for fuel quality. The addition of secondary-lubricity-additives by the customer is not recommended. – A cetane number of at least 45 is required for fuels in accordance with ASTM D975. A cetane number above 50 is preferable, especially with temperatures below 0°C. Diesel fuel at low temperatures (winter operation)
Diesel fuel precipitates paraffin crystals as the temperature drops. This increases flow-resistance in the fuel filter to such an extent that a sufficient supply of fuel to the diesel engine can no longer be guaranteed. In temperate climates, cold flow is guaranteed up to: 0 °C from 15/04. to 30/09 -10 °C from 01/10. to 14/11 / 1.3. - 14.04. -20 °C from 16/11 to 29/02 according to DIN EN 590. If the cold-flow properties of the diesel fuel are insufficient or with lower ambient temperatures than -20°C, we recommend using a fuel filter heater. Other approved diesel fuels: Diesel fuel complying with DIN EN 590 with up to 5% vol. FAME.
3.7.2 Lube oil specifications
Lubricating oils for diesel engines Only high-alloy lube-oils are used nowadays for modern diesel engines. They are comprised of base oils which feature combined admixtures (additives).

3.7.3 General recommendations
Coolant for the diesel engine The cooling system will only function reliably if it is working under pressure. It is therefore imperative that it is kept clean and watertight, that the radiator cap valve and working valves are functioning correctly and the necessary coolant level is maintained. The corrosion inhibitor/antifreeze authorised by LIEBHERR guarantees sufficient protection against cold, corrosion and cavitation, do not corrode seals and hoses and do not foam up. Coolants which contain inadequate or ill-prepared corrosion inhibitor/ antifreeze could cause a malfunctioning of aggregates or parts in the cooling circuit as a result of cavitational or corrosive damage. Furthermore, heatinsulating sedimentation can result at heat-exchanging parts, leading to overheating, and then to malfunctioning, of the engine. Note Emulsifiable corrosion inhibition oils may are impermissible. ! In special cases, it is permissible to use corrosion inhibitors.

Crankshaft flywheel speed sensors – B711/B712 For safety reasons, two identical speed sensors are used on the crankshaft. The two speed sensors, B711 and B712, are attached to the engine flywheel housing and their job is to record the speed and position of the crankshaft. The first sensor (B711) is the working sensor; if it fails, the system automatically switches to the second – backup – sensor (B712). The signal voltage, whose frequency is proportional to the speed, is used for: – Controlling the fan drive – Starting the emergency steering pump check – Controlling the diesel engine – Indicating the engine speed – Power limiting control – Overspeed protection – 0-inching control
Design The speed sensors are Hall-effect sensors. Hall-effect sensors are electromagnetic components with a permanent magnet and a Hall element (Hall IC). The distance between the sensor and the flywheel ring gear is fixed. Distance “a” = 0.5 - 2 mm
Function description Speed sensor location
Basic function If a Hall-effect sensor has voltage supplied and is put vertically into a magnetic field, it provides an output voltage. This signal voltage modulates proportionally to the speed of the ring gear on the flywheel and is provided to the engine electronics as a frequency signal. Attention Never measure resistance on a Hall-effect sensor.

Refuelling pump The refuelling pump 5 is a rotary vane pump which draws in fuel via the intake line 6 and the intake line extension 7 with suction strainer 8, from the container 9 and pumps it through the discharge line 4 to the fuel tank 3 of the machine. The refuelling pump 5 can be switched on and off using the removable key 2. The refuelling pump 5 is filled with fuel via the discharge line before it is first used. This means it is self-priming. The diesel fuel also lubricates the mechanical seals in the pump. A check valve in the intake port prevents the refuelling pump 5 from running empty. This means the pump remains self-priming. The DC motor does not have internal thermal protection; it is designed to run for a maximum of 15 minutes.

Function description Air filter unit The primary element 2 and the secondary element 1 of the dry air filter are designed to ensure maximum protection for the engine at very long service intervals. The primary element 2 with radial sealing at the filtered air connection in the filter housing 6 is subject to scheduled and non-scheduled maintenance. The secondary element 1 acts as a back-up if the primary element 2 is damaged. The secondary element 1 is not a service filter. It must be replaced if necessary. The dust extraction valve 5 automatically removes dust from the service cap 3. The tangential arrangement of the intake port sets the air into fast rotation, so that large dust particles are thrown by centrifugal force against the housing and accumulate in the service cap 3 due to the air flow. At idle speed, the accumulated dust particles in the service cap 3 are carried outside via the dust extraction valve 5 by the vibrations in the intake air. The service cap 3 must be fitted so that the dust extraction valve 5 points down. With the engine running at lower idle speed, you should clearly feel air pulsating at the dust extraction valve 5.

Pressure regulation by the proportional pressure relief valve
How the proportional pressure relief valve works When the solenoid 1 is not energised, the proportional pressure relief valve acts like a pilot-controlled pressure relief valve. The pressure acting at “P” passes through the primary restrictor 8 to the spring chamber of the main piston 7 and acts via the secondary restrictor 5 on the secondary piston 4. The pressure equalisation on the main piston 7 causes the primary spring 6 to close it. If the pressure on the secondary piston 4 becomes so high that the set force of the secondary spring 2 is exceeded, the secondary piston 4 opens, allowing oil to flow into the tank chamber. This gives rise to a difference in pressure in front of and behind the main piston 7, causing it to open. If the solenoid 1 is energised, a magnetic force is generated depending on the current. The magnetic force acts on the iron core 3, pulling it back according to the current strength. This magnetic force reduces the set spring force of the secondary spring 2 accordingly. This causes the proportional valve to open at a lower system pressure.
Fan speed regulation The proportional pressure relief valve acts as a bypass on the gear motor. LBH/Version 01/10.2006/en/hd/22.02.2007
At low temperature the bypass is almost fully open. Most of the pump flow goes through the bypass valve to the tank. The fan turns at low speed (minimum speed = dragging speed). As the temperature rises, the bypass valve closes proportionally. The gear motor turns the fan faster.
Failsafe function The failsafe function is as follows: if the power supply to the proportionally controlled pressure relief valve fails, the bypass closes. The full flow of the gear pump drives the gear motor. The fan turns at maximum speed.

The hydrostatic travel drive operates in a closed circuit. The variable displacement pump 20 pumps oil directly to the variable displacement motors 33 and 40. The oil returning from the variable displacement motors is pumped back to the intake side of the variable displacement pump. 1st gear: At low speed or high tractive force, both motors pivot out to a wide angle. This provides a low output speed and a high torque to the motors. If the travel speed is increased, both motors pivot inwards. 2nd gear: Motor 33 is uncoupled (not turning) and at an angle of 0°. Motor 40 moves to a certain angle depending on the travel speed. 3rd gear: Motor 40 is uncoupled (not turning) and at an angle of 0°. Motor 33 moves to a certain angle depending on the travel speed. Maximum travel speed is achieved at an angle of approximately 15°.

The variable displacement pump operates in a closed circuit. It pumps the oil directly to the variable displacement motors. The oil flowing back from the motors is fed back to the intake side of the pump. The main electronics (master) control the pump. Depending on the operating state of the machine, the control pressure proportional valve 5 is activated by the main electronics. The proportional valve regulates the control pressure and therefore the pump flow. At high load, the pump is adjusted to a lower displacement by the reaction forces from the high pressure. The travel direction valve 3 determines the direction in which the displacement pump operates and thus the travel direction of the machine. The pressure cut-off 2 limits the maximum operating pressure within the closed circuit. The pressure relief valves 4 for forward and reverse travel direction protect the travel drive from excessive pressure peaks. L550 - 456 / from 16978 L556 - 454 / from 15653

Service Manual See the detailed description in the section on the variable displacement pump. Variable displacement pump regulation The main electronics (master) control the variable displacement pump. The following parameters affect the control of the pump: – Gas pedal position – Inching function – Tractive force control – Excess hydraulic oil or coolant temperature – Engine overspeed or excessive road speed
Gas pedal position
When gas pedal is depressed, the current to the control pressure proportional valve is increased and the variable displacement pump pivots out. The control pressure proportional valve is only energised when the engine speeds exceeds 930 rpm. The current is then increased to the set value according to the engine speed.
Inching function
When the inch/brake pedal is depressed, the main electronics (master) reduce the current to the control pressure proportional valve and hydrostatic braking takes place. At excess engine speeds of 2450 rpm and above, the inching function is gradually reduced, and at 2600 rpm it is completely deactivated. This prevents engine overspeed when travelling downhill. If the inching angle sensor fails, the inching function is gradually deactivated within 20 seconds.
Tractive force adjustment
If tractive force control is activated, the main electronics (master) reduce the maximum current to the control pressure proportional valve. This restricts the tractive force to the set level. The following parameters are required for tractive force control: – The tractive force control button must be switched on – The machine must be moving forward – The machine must be in 1st gear (even with kickdown) You can use the two buttons to adjust the tractive force as required in a range of 100% to 70%.
Overheating
If the hydraulic oil (90 - 95 °C) or the coolant (90 - 100 °C) overheats, the main electronics (master) reduce the current to the control pressure proportional valve. The current is reduced gradually to 40% of the maximum level. The control pressure proportional valve is energised normally again when the temperature falls back below the threshold.
Engine overspeed or excessive road speed
Above a certain speed in each gear, the main electronics (master) starts gradually reducing the current to the control pressure proportional valve to 200 mA. At even higher road speeds or engine or motor overspeed, the overspeed protection function is activated. The rear axle is braked using replenishing pressure from the variable displacement pump.

Travel Hydraulics Variable displacement motors The variable displacement motors drive the transmission. A higher or lower torque is transferred to the transmission, depending on the pivot angle and pressure.
The flow from the displacement pump reaches the variable displacement motor via pressure connection A or B. In the process, the regulating pistons which move along the cylinder of the rotary group are subjected to pressure. The resulting force turns the drive shaft and generates a certain torque. The main electronics (master) control the motors. Depending on the operating state of the machine, the proportional valves 3 on the variable displacement motors are activated by the main electronics. This adjusts the pivot angle and displacement to the current operating condition. The discharge valve 4 in the variable displacement motor 2 is employed in the closed circuit to avoid heat build-up. In the process, oil is discharged from the low pressure side of the closed circuit and fed to the hydraulic tank. The replenishing pump replaces this oil with cooled oil.

Variable displacement motor power limiting control
Power limiting control comes into affect when the engine is excessively suppressed due to load. This can occur while driving and additionally operating the working hydraulics or steering. The main electronics (master) increase the current at the proportional valve of the motors until the engine speed is back in the normal range. The motors then pivot out again.
Inching function
When the inch/brake pedal is depressed, the main electronics (master) increase the current to the motor proportional valve and hydrostatic braking takes place.
Vmax function
With the Vmax function, the motors move towards a set displacement which corresponds to the preselected speed at full throttle. This means that the road speed decreases as the engine speed is reduced. The function is only activated when travelling forward in first or second fixed gear. The current speed when the Vmax button is pressed is stored. The machine then reaches this speed at full throttle.
Engine overspeed or excessive road speed
If the engine overrevs when travelling downhill, the motors pivot to a smaller angle. If the engine speed exceeds a critical level, overspeed protection is activated. The rear axle is braked. Overspeed protection is also activated if the variable displacement motors overrev.
During bearing flushing, fresh, cooled oil is directed to the tapered roller bearings and into the housing of the variable displacement motors. The hot oil is pumped out. The return oil from the fan motor 1 is pumped to the port U of the motors. The orifice 10 ensures that the oil is distributed evenly to both motors.

Travel Hydraulics The scavenging pump 2 draws oil from the connection T on both variable displacement motors. The hot oil flows to the collector pipe 7 and the oil cooler 6, and through the return suction filter 4 back to the hydraulic tank 5.
Hydraulic tank The hydraulic tank provides filtered oil for the replenishing pump of the travel hydraulics. The replenishing pump draws up oil from the hydraulic tank via the connection 1. A pre-tension valve in the return suction filter 3 preloads the suction side of the replenishing pump with a pressure of 0.5 bar. The replenishing pump is better able to draw up the oil for cold starts. This means that the pressure in the hydrostatic control circuit increases more quickly and a better drive performance is achieved. The oil returning from the travel hydraulics is directed over the oil cooler. The oil is then pumped back through the connection 2 and the return suction filter 3 to the hydraulic tank. The bleeder filter 4 compensates for pressure differences inside the hydraulic tank by providing appropriate ventilation.

The variable displacement pump is designed for hydrostatic drives in a closed circuit. The pump delivers directly to the variable displacement motors. The oil flowing back from the motors is fed back to the opposite side of the pump. The main electronics (master) control the pump. Depending on the operating state of the machine, the control pressure proportional valve 9 is activated by the main electronics (master). The proportional valve regulates the control pressure and therefore the pump flow. LBH/Version 01/10.2006/en/dw/26/01/2007
At high load, the pump is adjusted to a lower displacement by the reaction forces from the high pressure. The travel direction valve determines the direction in which the displacement pump operates and the travel direction of the machine. The pressure relief and replenishing valves A and B protect the travel drive from excessive pressure peaks. At the same time, the valves act as replenishing valves for the closed circuit. The pressure cut-off limits the maximum operating pressure within the closed circuit.

Control of the pump The main electronics (master) control the pump. Depending on the operating state of the machine, the control pressure proportional valve is activated by the main electronics. The proportional valve regulates the control pressure and therefore the pump flow. The following parameters affect the control of the pump: – Gas pedal position – Inching function – Tractive force control – Excess hydraulic oil or coolant temperature – Engine overspeed or excessive road speed
Control pressure proportional valve Depending on the operating state of the machine, the control pressure proportional valve is activated by the main electronics (master). The valve reduces the pressure in the PST channel in proportion to the magnet current. It operates largely independently of the PSP control pressure.
In the de-energised state, the PST control pressure duct is connected to the tank T. The more the current increases, the higher the control pressure. The maximum level is limited by the replenishing pressure. Depending on the current to the proportional valve 3, the control piston 2 is moved closer to or further from the regulating springs 1. This adjusts the pressure in the PST duct.

As the swivel angle increases, the pump flow is increased. The drive torque is increased. When the swivel angle is reduced, the flow rate of the pump is also reduced. The drive torque is reduced. When in the zero position, the pump flow is also zero. The strong spring centring in the servo cylinder keeps the swash plate in the zero position if no control signals are present. The zero position can be mechanically adjusted.

The operating pressure controls the valve. When the maximum operating pressure has been reached, the tappet 6 and the valve piston 2 are pushed against the pressure spring 1. The control pressure channel 3 is linked to the tank outlet 5, and servo oil drains off. The control pressure drops and the variable displacement pump swivels to a smaller flow rate. The variable displacement pump then delivers just enough oil to attain the maximum pressure.

Regulation of the variable displacement motors during acceleration 1st gear: At low speed, both motors pivot to a 25° angle. The greatest torque is transferred to the transmission. If the travel speed is increased, the motors simultaneously pivot inwards. The shift range is reached at around 6 km/h. Motor 1 moves back towards 0° and motor 2 towards 23°. Motor 1 reduces its torque and motor 2 increases its torque. L550 - 456 / from 16978 L556 - 454 / from 15653 L566 - 460 / from 14171

Once motor 1 reaches an angle of 0°, the coupling 1 opens in a loadfree condition. 2nd gear: In 2nd gear, only variable displacement motor 2 is active. Motor 1 is uncoupled and at an angle of 0°. As the speed is increased, motor 2 gradually reduces its angle. The next shift range is reached at around 17 km/h. Motor 1 is coupled again and moves to a wide angle. At the same time, motor 2 moves to 0°. Motor 2 is then uncoupled. 3rd gear: In 3rd gear, only variable displacement motor 1 is active. Initially, motor 1 is at an angle of 25°. In this range, the variable displacement pump takes control. At speeds higher than 23 km/h, motor 1 moves towards a smaller angle.
Variable displacement motor bearing flushing
The return oil from the fan motor 1 is pumped to the port U of the motors. The orifice 10 ensures that the oil is distributed evenly to both motors. The scavenging pump 2 draws oil from the connection T on both variable displacement motors. The hot oil flows to the collector pipe 7 and the oil cooler 6, and through the return suction filter 4 back to the hydraulic tank 5.

The flow from the displacement pump reaches the variable displacement motor via pressure connection A or B. In the process, the regulating pistons which move along the cylinder of the rotary group are subjected to pressure. The resulting force turns the drive shaft and generates a certain torque. The torque at the drive shaft depends on the swivel angle and on the operating pressure in the closed circuit. The speed of the drive shaft depends on the pump flow and on the swivel angle of the variable displacement motor. – As the swivel angle decreases, the speed increases and the potential torque is reduced. – As the swivel angle increases, the torque increases and the potential speed is reduced.

Travel Hydraulics Variable displacement motors
Electro-proportional control (EP) Depending on the energisation of the proportional magnet 7, the variable displacement motor is moved to the required angle. When the proportional magnet not energized, the motor is held at the 0° angle by the high pressure acting on the small servo piston face 2. When the proportional magnet is energised, above a certain current the control piston 6 is pushed up against the regulating springs 5 and 4. Highpressure oil flows via the control piston 6 to the large piston face 1 and the variable displacement motor moves out to a wider angle. During regulation, the control piston 3 is pushed down, increasing the tension in the regulating spring 4. This stops the regulation process if the current at the proportional magnet is not further increased. If the current is increased, the force of the two regulating springs is overcome and the motor continues moving to a wider angle. The maximum pivot angle is reached at a current of around 600 mA. The force of the proportional magnet is go great that it overcomes the spring force even at a wide pivot angle. The adjusting screw 8 is used for adjusting the regulating springs 5 (basic setting). Adjust the regulating springs 5 so that the motor is moved to a 25° angle at 600 mA on the proportional magnet. The main electronics (master) control the speed with which the variable displacement motor is moved. This means no swivel restrictors are required.
Cooling by the discharge valve The discharge valve is used in the closed circuit to avoid excessive heat build-up. In the process, oil is discharged from the low pressure side of the closed circuit and fed to the hydraulic tank. The replenishing pump replaces this oil with cooled oil. When the machine is at rest, the pressure is the same on both faces of the valve piston 4. The two return springs 5 push the valve piston 4 to the centre position. No oil is discharged in this position.
LBH/Version 01/10.2006/en/dw/26/01/2007
When the machine moves, the pressure in the duct 6 or 7 increases and moves the valve piston 4 towards one of the return springs 5. The low pressure side is opened and a defined quantity of oil flows via the orifice 1 and the pressure relief valve 2 to the hydraulic tank.

Service Manual Hydraulic tank The hydraulic tank provides filtered oil for the working hydraulics. The working hydraulics pump draws up oil from the hydraulic tank via the shut-off connection 1. The returning oil is pumped back through the connection 2 and the return suction filter 3 to the hydraulic tank. The bleeder filter 4 compensates for pressure differences inside the hydraulic tank by providing appropriate ventilation. See the detailed description in the section on the hydraulic tank.
Working hydraulics pump The working hydraulics pump draws up oil from the hydraulic tank and pumps it to the control block. The flow regulator 2 (load sensing) ensures that the working hydraulics pump only delivers as much oil from the hydraulic tank as the working hydraulics currently need. The power regulator 1 ensures that the maximum current consumption of the variable displacement pump is never exceeded. See the detailed description in the section on the working hydraulics pump.
Control block The control block contains the spool valves for the lift cylinder 3 and the tilt cylinder 4. The LS pressure relief valve 7 limits the maximum pressure of the working hydraulics pump. The primary pressure relief valve 5 additionally limits the maximum pressure of the working hydraulics pump. The secondary pressure relief valves 2 protect the hydraulic system against pressure peaks from the consumer units. The float position/ride control solenoid valve 6 is activated for the float position and ride control. See the detailed description in the section on the control block.
The working hydraulics are actuated by a separate control circuit. The spool valves in the control block 1 are hydraulically actuated by the pilot control unit 2. The variable displacement pump 5 (replenishing pump) of the travel hydraulics takes the required servo oil and pumps it through the pilot control solenoid valve 4 to the pilot control unit 2. See the detailed description in the section on the pilot control unit.

The working hydraulics are equipped with the following standard functions: – Working movements for the lift and tilt cylinders – Ride control – Float position – Automatic bucket return-to-dig function – Lift kick-out The working hydraulics system operates in an open circuit. The working hydraulics pump 20 draws up oil from the hydraulic tank 1 and pumps it to the control block 50. The returning oil is pumped through the return suction filter 5 back to the hydraulic tank 1. The control block is activated via the hydraulic pilot control unit. The control block contains the spool valves for the lift and tilt cylinders. The LS system in the control valve block distributes the flow of the working hydraulics pump to the consumer units independently of load. LBH/Version 01/10.2006/en/dw/05/02/2007
The ride control system attenuates the bouncing and pitching vibrations of the machine while it is travelling, thus greatly increasing comfort and safety.

Working hydraulics
Service Manual Hydraulic tank The hydraulic tank provides filtered oil for the working hydraulics. The working hydraulics pump draws up oil from the hydraulic tank via the shut-off connection 1. The returning oil is pumped back through the connection 2 and the return suction filter 3 to the hydraulic tank. The bleeder filter 4 compensates for pressure differences inside the hydraulic tank by providing appropriate ventilation. See the detailed description in the section on the hydraulic tank.
Working hydraulics pump The working hydraulics pump draws up oil from the hydraulic tank and pumps it to the control block. The flow regulator 2 (load sensing) ensures that the working hydraulics pump only delivers as much oil from the hydraulic tank as the working hydraulics currently need. The power regulator 1 ensures that the maximum current consumption of the variable displacement pump is never exceeded. See the detailed description in the section on the working hydraulics pump.
Control block The control block contains the spool valves for the lift cylinder 3 and the tilt cylinder 4. The LS pressure relief valve 7 limits the maximum pressure of the working hydraulics pump. The primary pressure relief valve 5 additionally limits the maximum pressure of the working hydraulics pump. The secondary pressure relief valves 2 protect the hydraulic system against pressure peaks from the consumer units. The float position/ride control solenoid valve 6 is activated for the float position and ride control. See the detailed description in the section on the control block.
The working hydraulics are actuated by a separate control circuit. The spool valves in the control block 1 are hydraulically actuated by the pilot control unit 2. The variable displacement pump 5 (replenishing pump) of the travel hydraulics takes the required servo oil and pumps it through the pilot control solenoid valve 4 to the pilot control unit 2. See the detailed description in the section on the pilot control unit.

The working hydraulics pump operates in an open circuit. It draws up oil directly from the hydraulic tank and pumps it to the control block. The flow of the of the working hydraulics pump is determined by the angle and speed of the pump. The governors fitted to the working hydraulics pump determine the angle of the pump and therefore the pump flow.
Pump control

The swash plate 1 of the working hydraulics pump is moved out by the control piston 2. The operating pressure constantly acts in the piston chamber 3. This causes the pump to swivel out.

Working hydraulics Working hydraulics pump
The swash plate is returned to its initial position by the return piston 5. Pressure oil is pumped into the piston chamber 4. The return piston is controlled by the governors fitted on the working hydraulics pump. The working hydraulics pump flow is controlled by the following governors: – Flow controller – Power regulator The operating state of the working hydraulics system governs which governor is currently activated. If the working hydraulics demand only a small amount of oil or none at all, the flow regulator restricts the working hydraulics pump to the required amount. If the set power limit is reached at a certain flow and increasing pressure, the flow regulator reduces the working hydraulics pump flow.
Flow regulation The load sensing system ensures that the working hydraulics pump only delivers as much oil from the hydraulic tank as the working hydraulics currently need.
LBH/Version 01/10.2006/en/dw/05/02/2007
When the working hydraulics are not in use, the oil flow is blocked by the spool valves in the control block and the working hydraulics pump is reduced to minimum flow (leak flow). Connection 2 is depressurised. The high pressure pushes the piston 3 against the pressure springs 1 which determine the standby pressure in the system. The control piston 3 opens the high pressure duct 4 to the duct 5 and the return cylinder reduces the pump to leak flow.

4 High pressure duct 5 Duct to return cylinder 6 Flow controller
If the working hydraulics need oil, the pressure at the connection 2 increases. The pressure and force of the springs 1 move the control piston 3 against the high pressure. The duct 5 opens to the tank connection 7. The open duct relieves the return cylinder and the pump delivers the required oil quantity.

Pump pressure limitation The maximum operating pressure in the system is limited by the LS pressure cut-off valve 1 in the control block. The LS pressure, which affects the flow regulator 2, is set to a particular value.
LS pressure cut-off in the control block
The power regulator controls the displacement of the working hydraulics pump according to the operating pressure, so that a specific drive power is never exceeded. The power regulator works on the principle of hyperbolic control. It regulates the pump exactly along the preset power curve 1 (flow x high pressure).

Working hydraulics Working hydraulics pump
Pump output diagram The operating pressure acts via the ring face 8 of piston on the control lever 11. This produces a variable levering force depending on the position of the control cylinder (flow) and acts on the externally adjustable spring 6. If the force on the lever 11 generated by the operating pressure exceeds the set spring force, the valve piston 5 is moved. Pressure oil flows through the duct 3 to the return cylinder and the working hydraulics pump displacement is reduced.

Working hydraulics in active state The spool valves in the control block are hydraulically actuated by the pilot control unit.
Control block in active state When the tilt-in function is actuated, oil flows from the pilot control unit to the connection a1. This pushes the spool valve 2 to the left. The spool valve 2 opens the pump duct P to the pressure balance 3 via the control notches 1. If the pump pressure exceeds the pressure at the tilt cylinder, the pressure balance in the load valve opens and oil flows through the connection A1 to the tilt cylinder. The oil returning from the tilt cylinder flows through the connection B1 and the spool valve to the tank channel T.

Working hydraulics Working hydraulics pump
Pilot control unit The pilot control unit controls the spool valves in the control block. The control pressure increases smoothly according to the deflection of the lever. The pilot control unit contains retaining solenoids for the bucket return-to-dig, lift kick-out and float position functions. These solenoids hold the control lever in the maximum position until the solenoid current is switched off. See the detailed description in the section on the pilot control unit.
Variable displacement pump with replenishing pump The replenishing pump 1 is part of the variable displacement pump 2 of the travel hydraulics. The replenishing pump delivers oil for the following components and functions: – Travel hydraulics control circuit – Replenishing oil in the closed circuit – Pilot control of the working hydraulics – Overspeed protection (rear axle braking function) The maximum pressure of the replenishing pump is limited by the replenishing pressure relief valve. The design and functions are described in the sections on the travel hydraulics and the variable displacement pump.
Solenoid valve block The solenoid valve block 4 contains the pilot control solenoid valve 2 and the pilot control hydro accumulator 1. When the machine is started or when the starter switch is in position 1, the pilot control solenoid valve is activated automatically. Control oil flows to the pilot control unit and the working hydraulics can be operated. The hydro accumulator 1 and check valve (starter switch in position 1) allow the lift arms to be lowered and the working attachment to be tilted out, even when the engine is not running. The working hydraulics lockout button deactivates the pilot control solenoid valve. The P connection in the pilot control unit is relieved towards the hydraulic tank and the working hydraulics cannot be used. See the detailed description in the section on the pilot control unit solenoid valve.

The pilot control device activates the pistons in the control block hydraulically. It works on the basis of directly controlled pressure relief valves. When the control lever is moved, it supplies oil to the appropriate connection. The pressure regulation of the valves in the pilot control device depends on: – The position of the control lever – The properties of the individual regulating springs The retaining solenoids allow each function to be electromagnetically locked. Its magnetic force holds the control lever in its end position.

Idle state
In the idle state, the control lever is held in the zero position by the return spring 2. The connection 6 is connected via the hole 5 to the tank connection T.
Control valve in idle state / Control valve in active state Regulating phase
When the control lever is moved, the tappet 7 pushes against the return spring 8 and the regulating spring 9. The regulating spring 9 pushes down the regulating piston 10 and closes the connection of the port 12 and the tank connection T. At the same time, the connection 12 is connected via the hole 11 to the connection P. The control phase begins as soon as the force of the regulating spring 9 and the force of the hydraulic pressure at the connection 12 are equal. The regulating piston 10 is in equilibrium. The interaction of the regulating piston 10 and the regulating spring 9 means that the pressure at the connection 12 is proportional to the stroke of the

tappet 7 and therefore to the position of the control lever. The pressure regulation which is proportional to the position of the control lever allows the spool valves in the control block to be moved proportionally to the pressure.
Electromagnetic locking The following functions have electromagnetic locking: – Lift kick-out – Bucket return-to-dig – Float position The pressure spring 1 is attached under the tappet 3 and the spring sleeve 2. Just before the end of the stroke of the tappet and the control lever, the operator must apply additional force to tension the pressure spring 1. This shows the operator that the control lever is at its end position / maximum deflection. At the end position (maximum deflection) of the control lever, the ring 5 comes into contact with the anchor magnet 4. When the solenoid is activated, its magnetic force holds the control lever in its end position.
LBH/Version 01/10.2006/en/dw/05/02/2007
Unlocking takes place automatically by switching off the solenoid current using the proximity switch or by pulling back the control lever.

Design
Components of the pressure switch 1 Connection contact 2 Adjusting screw 3 Pressure spring
4 Switch contact 5 Membrane 6 Housing
The ride control pressure switch is installed under the pilot control unit in the control line for lowering the lift arms.
Function description Basic function The membrane pressure switches are for switching electric circuits on and off. The hydraulic pressure acts via a membrane on an adjustable spring. When a set value is reached, the electric contact opens and the circuit is interrupted. This type of membrane pressure switch is known as "normally closed".
Deactivating the ride control function The ride control pressure switch prevents ride control from being activated at the same time as the float position or lift arm lowering function. LBH/Version 01/10.2006/en/dw/05/02/2007
When the float position or lift arm lowering function is not activated, the contact in the ride control pressure switch is closed. This means that ride control can be activated. When the float position or lift arm lowering function is activated, the pressure on the ride control pressure switch increases and the electrical contact in the switch opens. This prevents ride control from being activated at the same time.

Function description Extension and retraction The hydraulic cylinder is a double-action cylinder with a piston at one end. The maximum forces in the cylinder depend on the maximum operating pressure and the active surfaces. When extending, the piston face is active; when retracting, the smaller ring face is active. This means the force when extending is greater than when retracting. The piston speed is inversely proportional to the force. It is faster when retracting than extending.

Filter unit The filter unit consists of the following components: 1 Return suction filter 2 Return strainer 3 Bleeder filter 4 Suction line from replenishing pump The return suction filter 1 filters the oil flowing back from the working and travel hydraulics. The oil flows from the inside outwards through the filter. At the same time the filter acts as a suction filter for the replenishing pump of the hydrostatic travel drive. The replenishing pump draws up the filtered oil via the connection 4. To prevent excessive changes of pressure inside the hydraulic tank, air must be exchanged with the atmosphere outside. The bleeder filter 2 provides the connection to the outside. To prevent contamination, the air taken in from outside passes through a fine filter. A valve with a spring provides a slight pressure inside the hydraulic tank. The return strainer 3 filters some of the oil returning from the entire hydraulic system. The filtered oil then flows back to the hydraulic tank.

The oil flowing back from the working and travel hydraulics is pumped through the connection 1 to the return suction filter 3. The oil flows from the inside outwards through the return suction filter 3 and is cleaned. The magnetic rod 2 attracts larger metal particles from the oil flowing past. This also increases the lifetime of the filter. The outside of the filter is connected to intake connection 5 of the replenishing pump. More oil flows from the working and travel hydraulics to the return and suction filter than is drawn up by the replenishing pump. The excess oil flows through the pre-tension valve 7 to the hydraulic tank.
Oil supply to the replenishing pump The returning oil flows from the inside outwards through the return suction filter 1. The replenishing pump of the travel hydraulics draws up some of the oil from the lower chamber 2 via the intake connection 4. The pre-tension valve 3 preloads the intake connection 4 of the replenishing pump with a pressure of 0.5 bar. The excess oil flows through the pretension valve 3 to the hydraulic tank.

If there is insufficient oil to supply the replenishing pump, it can draw up oil from the hydraulic tank. Oil flows through the replenishing strainer 5 and the replenishing valve 6 to the intake connection 4 of the replenishing pump. There may be too little oil in the filter element, for instance after it is changed.

Working hydraulics Hydraulic tank
Bypass valve for pressure relief The bypass valve 4 prevents excess pressure in the return system. Excess pressure can arise if the filter element 1 is dirty or if the oil is not sufficiently viscous. If a certain pressure is reached, the bypass valve 4 opens. The oil then flows through the duct 3, the bypass valve 4 and the return strainer 5 to the hydraulic tank.

The steering system operates in an open circuit. The variable displacement pump 20 draws up oil from the hydraulic tank 1 and pumps it through the valve block 40 to the servostat 30. The servostat supplies oil to the two steering cylinders when the steering wheel is moved. The load sensing system ensures that the pump 20 only pumps as much oil as is actually required. The emergency steering system allows steering movement if the variable displacement pump fails. The emergency steering pump 45 delivers oil via the valve block 40 to the servostat 30. The hydro accumulators 17 and 18 on the steering cylinders absorb steering movements. The absorber system in the steering cylinder prevents the front and rear sections from bumping other at full articulation.
Hydraulic tank The hydraulic tank provides filtered oil for the steering system. The variable displacement pump draws up oil from the hydraulic tank via the connection 1. The returning oil from the servostat is pumped back through the oil cooler and the connection 3 via the return suction filter 4 to the hydraulic tank. Leak oil from the variable displacement pump is directed through the connection 2 via the return strainer 5 to the hydraulic tank. The bleeder filter 6 compensates for pressure differences inside the hydraulic tank by providing appropriate ventilation. LBH/Version 01/10.2006/en/dw/26/01/2007
See the detailed description in the section on the hydraulic tank.
Variable displacement pump The pump draws up oil directly from the hydraulic tank and pumps it through the valve block to the servostat. The load sensing system ensures that the variable displacement pump only provides as much oil as the steering system currently needs. The pressure cut-off valve 2 limits the maximum pressure of the pump. See the detailed description in the section on the variable displacement pump.

Steering System
Service Manual Valve block The valve block directs the oil from the variable displacement pump or the emergency steering pump to the servostat. The emergency steering pressure switch 1 monitors the pressure of the variable displacement pump. If the pressure at the emergency steering pressure switch 1 is too low, the emergency steering pump is automatically activated. This can happen if the diesel engine shuts down or if the variable displacement pump fails. The check valves 2 and 3 prevent the oil from flowing back to the pumps. See the detailed description in the section on the valve block.
Servostat The servostat is connected to the steering column. The steering wheel actuates the metering pump and valve slider in the servostat, causing the steering system to move. If the steering wheel is moved quickly, the flow booster system pumps some of the oil via the spool directly to the steering cylinders. This facilitates fast steering on rough terrain. When the steering wheel is moved slowly, the flow booster is not activated. All the oil is pumped through the spool and the metering pump to the steering cylinders. This facilitates sensitive steering on roads. Two pressure relief valves protect the steering cylinder and servostat from excessive pressure peaks. See the detailed description in the section on the servostat.
Steering cylinder The steering cylinders are connected to the front and rear sections. The servostat supplies oil to the steering cylinders during steering. The hydro accumulators on the steering cylinders absorb steering movements. The absorber system in the steering cylinder prevents the front and rear sections from bumping other at full articulation. See the detailed description in the section on the steering cylinder.
The emergency steering function allows the steering system to be operated if the engine or the variable displacement pump fails. The emergency steering pump is activated by the main electronics (master). See the detailed description in the section on emergency steering.
Emergency steering pump The gear pump 4 of the emergency steering pump is powered by the electric motor 2. The electric motor is switched on when necessary via the relay 1. In emergency steering mode the emergency steering pump draws up oil from the hydraulic tank and pumps it through the valve block to the servostat. The pressure relief valve 3 protects the pump from excess pressure. See the detailed description in the section on the emergency steering pump.

The steering pump operates in an open circuit. During operation, the pump delivers oil from the hydraulic tank through the valve block to the steering. The displacement of the steering pump is proportional to the input speed and the variable cylinder volume. The pressure cut-off valve 6 and flow controller 7 attached to pump housing affect the control unit of the pump. The pump control unit pivots the swash plate out of the zero position. When the swash plate pivots out, the piston stroke in the rotary group 1 increases and the pump starts delivering oil.

Steering pump
The system pressure constantly acts on the actuating cylinder 1. The actuating cylinder 1 pushes the swash plate 3 towards a wider angle and pump delivers oil. The return cylinder 2 moves the swash plate 3 against the actuating cylinder 1 to a smaller angle. The effective piston face of the return cylinder 2 is larger than that of the actuating cylinder 1. The oil pressure acting on the return cylinder 2 is controlled by the flow controller or pressure cut-off valve. In the pump control range, the oil pressure on the return cylinder is just enough to keep the forces of the actuating and return cylinders in equilibrium. This means the pump can maintain a specific pivot angle and pump a corresponding amount of oil.
Flow controller (load sensing) The load sensing system ensures that the variable displacement pump only provides as much oil from the hydraulic tank as the steering system currently needs. If the steering system needs oil, the load pressure at the connection 4 increases. The pressure and the force of the springs 5 push the piston 2 against the pump pressure. The duct A opens to the tank connection T. The open duct A relieves the return cylinder 3 and the pump delivers the required quantity of oil.

If the steering wheel is not moved, the load pressure at the connection 4 decreases. The pump pressure moves the piston 2 against the springs 5. The piston 2 opens the pump pressure duct P to the duct A and the return cylinder regulates the pump to the minimum flow.
Flow controller with no steering movement (pump does not deliver oil)
Pressure cut-off When the maximum operating pressure in the system has been reached, the pump moves back to the smallest angle and only delivers leak oil. The maximum operating pressure remains constant. When the pump reaches its maximum operating pressure, the piston 3 in the pressure cut-off valve 1 moves against the spring 4. This opens the duct A and pressure oil flows to the return cylinder.

When it is actuated, the servostat directs oil from the variable displacement pump to the steering cylinders. The oil supply to the steering cylinders is precisely metered according to the speed of the steering wheel. When the steering wheel is turned, the position of the internal rotary slider is turned in relation to the outer valve sleeve. This opens the valve, allowing a certain amount of oil to flow through the metering pump to the steering cylinder.
Flow booster

If the steering wheel is moved slowly, the entire flow is directed through the metering pump 3. The oil flowing to the steering system depends on the size of the metering pump. This allows very sensitive steering for travelling on roads. At faster steering speeds of more than 10 turns of the steering wheel per minute, additional holes in the spool open. Some of the oil flows through the metering pump 3, and more oil flows the spool 4 directly to the cylinders. The volumetric flow ration is 1:1.6. This allows very fast steering for rough terrain.
Flow regulation (load sensing) Load sensing ensures that the variable displacement pump only supplies the amount of oil currently needed by the steering system. The servostat reports the required amount of oil via the LS connection to the variable displacement pump. Steering system in inactive state
When the steering is not actuated, the duct P on the variable displacement pump 3 is blocked. The LS connection for controlling the pump is relieved via the spool to the tank connection T. The LS depressurised connection adjusts the variable displacement pump minimum flow.
Steering system in active state
When the steering is actuated, the spool 2 is moved. The connection P is connected to the connection LS and to the steering cylinder. The increase pressure at the LS connection causes the flow controller 4 to regulate the variable displacement pump 3 to the required oil quantity.
Pressure cut-off The pressure relief valves prevent excessive pressure peaks in the steering system. Pressure peaks can be caused by sudden loads while driving. Depending on the direction of the load, either the pressure relief valve 1 on the left steering cylinder or the pressure relief valve 2 for the right cylinder opens.

Extension and retraction The hydraulic cylinder is a double-action cylinder with a piston at one end. The maximum forces in the cylinder depend on the maximum operating pressure and the active surfaces. When extending, the piston face is active; when retracting, the smaller ring face is active. This means the force when extending is greater than when retracting. The piston speed is inversely proportional to the force. It is faster when retracting than extending.
Piston rod guide The piston rod is guided by the guide rings on the piston and in the piston rod bearing. L550 - 456 / from 16978 L556 - 454 / from 15653 L566 - 460 / from 14171

The elastic partition between the fluid and the nitrogen is a membrane 2, which is stretched in the accumulator 4. The closing head 3 prevents the membrane from being pressed into the inlet opening when the hydro accumulator is completely empty. The plug 1 allows the accumulator to be checked and topped up using the filling and testing device.
Function description Basic function The purpose of the hydro accumulator is to store hydraulic energy and supply it when needed.
LBH/Version 01/10.2006/en/dw/26/01/2007
It has the following applications: – To act as an attenuator for pressure peaks, for example for the ride control system or steering attenuation. – As an energy reserve to supply energy when needed, for example for the brake system.
Steering damper The hydro accumulators on the steering cylinders absorb steering movements when changing direction quickly. Also, the damping effect absorbs external influences on the machine, for example if the working attachment is driven against an obstacle.

During the safety test, the emergency steering pump is activated. The pump runs for 2 to 3 seconds. A pressure of 16 bar must be reached within this time. The contact on the emergency steering check pressure switch 6 closes. During the safety test, the emergency steering check symbol field 3 lights up. The emergency steering system is then operational and the emergency steering check symbol field goes out. If the pressure at the emergency steering check pressure switch 6 does not reach 16 bar, the check symbol field stays lit until the ignition is switched off. The safety test is interrupted after 3 seconds. The emergency steering field check symbol field indicates to the driver that the emergency steering system is defective.

Function description Basic function The gear pump of the emergency steering pump is powered by the electric motor. The electric motor is switched on and off via a relay. The gear pump draws up oil from the hydraulic tank as needed. The oil is pumped via the valve block to the servostat. A pressure relief valve protects the pump from excess pressure.
Gear pump with pressure relief valve The gear pump 1 of the emergency steering pump is protected by a pressure relief valve. By restricting the maximum pressure, this also prevents the electric motor from consuming too much current. The system pressure pushes the valve piston 2 against the spring 3. If the maximum pressure is reached, the valve piston 2 opens. This allows hydraulic oil to flow out to the intake side of the gear pump. The maximum pressure is determined by the pressure spring 3 and the adjusting disc 4.

Service Manual
Brake system The service brake is a hydraulic 2-circuit brake system. It acts on the wet discs in the front and rear axles. The brake system gear pump 3 draws up oil from the hydraulic tank 1 and pumps it to the compact brake valve 10. The accumulator charge valve 11 in the compact brake valve fills the hydro accumulators to a specified oil pressure. When the inch/brake pedal is slightly depressed (up to 2/3 of the way down), only the hydraulic inching function is activated via the inching angle sensor 17. When the inch/brake pedal is fully depressed (in the last third), oil flows from the hydro accumulators 22 and 28 via the pressure control pistons 18 and 19 to the brake pistons in the front and rear axles. This activates the wet disc brakes. At the end of the braking procedure, the oil flows into the hydraulic tank. The parking brake 25 is opened by oil pressure and closed by spring force. When the parking brake solenoid valve 16 is energised, oil flows from the parking brake hydro accumulator 23 to the parking brake and opens the callipers.
Hydraulic tank The hydraulic tank provides filtered oil for the brake system. The gear pump draws up oil from the hydraulic tank via the connection 1. The returning oil is pumped back through the return strainer 3 to the hydraulic tank. The bleeder filter 4 compensates for pressure differences inside the hydraulic tank by providing appropriate ventilation. See the detailed description in the section on the hydraulic tank.
Brake system gear pump The brake system gear pump 2 draws up oil from the hydraulic tank and pumps it through the connection 4 to the compact brake valve. The cooling system gear pump 3 and the brake system gear pump 2 have a shared intake port. See the detailed description in the section on the brake system gear pump.

Brake system Parking brake The parking brake is attached to the output shaft of the transmission 4 and thus acts on all four wheels.
The parking brake is opened by oil pressure and closed by spring force. When you start the engine and press the parking brake button, the solenoid valve 2 in the compact brake valve 1 is activated. Oil flows from the hydro accumulator 3 to the parking brake 5, where it acts on the brake cylinder and opens the callipers. When you press the parking brake button again or turn off the engine, the force of the springs in the brake cylinder closes the brake, thus generating the required braking torque on the brake disc. When the parking brake is closed, the LED in the parking brake button and the parking brake symbol field in the display light up. See the detailed description in the section on the parking brake.
Overspeed protection The overspeed protection prevents the engine and the variable displacement motors from overrevving, which can occur, for example, when driving downhill.
LBH/version 01/10.2006/en/dw/26/01/2007
When a set limit speed is exceeded, the overspeed protection solenoid valve 3 is activated. Oil flows from the replenishing pump 2 to the rear axle disc brake 5, causing the machine to slow down. See the detailed description in the section on overspeed protection.

The compact brake valve is supplied with oil by a gear pump. The integrated accumulator charge valve 9 and the pilot valve 7 fill the hydro accumulator with pressure oil. If the accumulator charge cut-off pressure is reached, the accumulator charge valve 9 switches the pump flow to circulate to the connection N. LBH/version 01/10.2006/en/dw/26/01/2007
If braking causes the accumulator pressure to fall to the accumulator charge cutin pressure, the accumulator charge valve 9 switches to accumulator charging. The brake circuits of the front and rear axles are separated by the inverted shuttle valve 5. The parking brake solenoid valve 1 provides pressure oil to the disc brake.
Service brake When the pedal is depressed in the first two thirds of its range, the hydraulic inching function is activated. This function is triggered by the angle sensor on the compact brake valve. If the pedal is depressed further, the pressure control pistons of the 2nd circuit control the pressure in the brake pistons in proportion to the pedal force. At the end of the braking procedure, the oil flows back to the hydraulic tank.

Components of the parking brake 1 Compact brake valve 2 Parking brake solenoid valve 3 Parking brake hydro accumulator
4 Transfer gear 5 Disc brake
The parking brake is a spring accumulator brake. The parking brake is opened by oil pressure and closed by spring force. The parking brake is supplied with oil by the compact brake valve 1. The accumulator charge valve of the compact brake valve 1 fills the parking brake hydro accumulator 3 to a specified oil pressure. The parking brake hydro accumulator 3 provides oil pressure via the solenoid valve 2 to open the parking brake. The solenoid valve 2 is actuated using the parking brake button. When the parking brake is opened, oil flows from the hydro accumulator 3 via the solenoid valve 2 to the disc brake 5.
Function of the parking brake switch The parking brake can only be released when the engine is running. When you start the engine and press the parking brake button 2, the parking brake solenoid valve is activated. The brake pressure then acts via the open parking brake solenoid valve on the brake cylinder, and opens the parking brake against the force of the brake callipers. The parking brake symbol field 3 on the display goes out.
LBH/version 01/10.2006/en/dw/26/01/2007
When you press the parking brake button 2 again or turn off the engine, the force of the springs in the brake cylinder closes the brake, thus generating the required braking torque on the brake disc. The parking brake symbol field 3 and the LED 1 in the parking brake button light up.

Function description Basic function of the disc brake
Disc brake in open position The two identical brake pads 5 and the brake calliper 1 slide freely on the guide pins 4, which are fastened in the transmission housing. When the brake is applied, it clamps the brake pads 5, creating a braking torque on the brake disk 3. The clamping force is generated by the cup springs 9. The piston 8 is pushed together with the pressure pin 2 and the front brake pad 5 towards the brake disc 3. When the front brake pad 5 comes into contact with the brake disc 3, the reactive force pushes the brake callipers 1 along the guide pin 4 until the rear brake pad 5 is also pressed against the brake disc 3. The parking brake is released by tensioning the entire cup spring set 9. Oil in the pressure chamber 7 pushes the piston 8 all the way back against the force of the cup springs 9.
LBH/version 01/10.2006/en/dw/26/01/2007
Rubber fittings on the guide pin 4 push the entire brake calliper to the right until the adjusting screw 6 touches the transmission housing. This moves the rear brake pad 5 away from the brake disc 3.

Design
Components of the hydro accumulator 1 Plug 2 Membrane
3 Closing head 4 Accumulator
The elastic partition between the fluid and the nitrogen is a membrane 2, which is stretched in the accumulator 4. The closing head 3 prevents the membrane from being pressed into the inlet opening when the hydro accumulator is completely empty. The plug 1 allows the accumulator to be checked and topped up using the filling and testing device.
Function description Basic function
It has the following applications: – To act as an attenuator for pressure peaks, for example for the ride control system or steering attenuation. – To act an energy reserve to supply energy when needed, for example for the brake system.

7 Rear axle disc brake Test connection: M5 Rear axle brake pressure
The overspeed protection prevents the engine and the variable displacement motors from overrevving, which can occur, for example, when driving downhill. When the engine or the variable displacement motors reach a set limit speed, the overspeed protection solenoid valve 6 is activated. Oil flows from the replenishing pump 4 to the rear axle disc brake 7, causing the machine to slow down.

Service Manual
Overspeed protection
Overspeed service code If the engine or the variable displacement motors overspeed, the machine reacts as follows: – The overspeed protection solenoid valve is energised – A service code appears in the display: E 5030 Overspeed on one of the variable displacement motors E 5032 Overspeed on variable displacement motor 1 E 5031 Overspeed on variable displacement motor 2 E 600B Overspeed on diesel engine – The warning buzzer sounds for one second. – Additionally, after 3 seconds of overspeed protection being active, the service code E 5029 appears.
The brake is activated according to the intensity of overspeed. The following situations may occur: Situation A: In the event of serious overspeed, for example on a steep slope, the brake activated constantly for more than 3 seconds. The service code E 5029 appears with a short warning tone. Situation B: Once the limit speed is exceeded, the machine is automatically braked until the speed falls back below the threshold. After a short time, the limit speed is exceeded again and the brake is activated again. If the brake is activated for longer than 3 seconds, the service code E 5029 appears with a short warning tone. This also happens if the brake intervention is briefly interrupted. Situation C: The machine is briefly braked. The speed then returns to the normal range.
The service code E 5029 only appears during reckless driving, for example at full speed down steep slopes. If the service code E 5029 is found several times in the memory, it may affect the warranty on the machine, especially if any damage was caused by overspeed. The service codes are stored in the main electronics A15.

Function description Basic function
However, the other electrical and electronic components are powered via the relay and fuse board.
Working floodlight fuse function The function of the working floodlights can be selected by plugging the fuses F31A, F31B, F32A, F32B, F33A and F33B: - When the fuses are plugged to terminal 30 the working floodlights work as soon as the main switch is turned ON. - When the fuses are plugged to terminal 15 the working floodlights only work when the ignition is turned ON. You can also choose a mixed function, for example by plugging the front working floodlights to terminal 15 and the rear floodlights to terminal 30.

Service Manual
Electrical system Electrical components
Fuse test The fuses on the relay and fuse board are divided into three categories. - Fuses for power supply from terminal 30 - Fuses for power supply from terminal 15 - Fuses to protect various functions (e.g. low beam, profile lights / parking light) Each fuse has an LED and can be tested by pressing the button S1. The fuse test depends on the electrical status. Only the fuses of the activated circuit can be tested: - When the main switch is on (terminal 30) only the LEDs on terminal 30 power supply fuses light up when the button S1 is pressed. - When the main ignition is on (terminal 15) the LEDs on terminal 30 and terminal 15 power supply fuses light up when the button S1 is pressed. - The LEDs to protect the various functions only light up when the corresponding function is activated.
LBH/Version 01/10.2006/en/hd/21/02/2007
If an LED does not light up, the fuse is defective.

A module must be addressed when it is replaced or installed. The input modules are delivered with the default address 45. The address is required in order to identify CAN bus messages. - Input module (sender) - Output module (receiver) Addressing is performed as follows: Connect the module Remove the ventilation and bleeder screw Unplug the PWR.X connector on the main electronics (master) Press the button 3 Switch on the ignition and keep the button pressed until the LEDs start flashing
Note: If you release the button too quickly, the module is in download mode for the outer core (orange flashes once, red flashes once). In this case, switch the module off and try again. The flashing LEDs indicate the module number (address): - The green LED flashes to indicate the 100s of the module number (1x = 100, 2x = 200) - The orange LED flashes to indicate the 10s of the module number (1x = 10, 2x = 20) - The red LED flashes to indicate the 1s of the module number (1x = 1, 2x = 2) Example: 1x green, 3x orange, 10x red = 130 All three LEDs briefly flash between each repeat of the number display.

The power supply for the terminal equipment is divided as follows: - Activation via banks, which consist of 4 terminal devices and have a single power source (fuse). - Direct activation from a fuse, where individual terminal devices are powered directly by a corresponding fuse. - Indirect activation from a fuse, where individual terminal devices are powered by a corresponding fuse via an upstream module. This configuration is required for switching off outputs in safety-critical states.

Mechanical transmission
The gearbox is elastically mounted in the rear section of the wheel loader and is driven by two variable displacement motors. The motors drive the two input shafts 2 and 4, which transfer the torque to the coupling sets 3, 5 and 6. The hydraulically actuated couplings consist of an inside-geared coupling cage, an outside-geared coupling hub, discs, piston, press plate and return springs. The outside-geared steel discs and inside-geared friction discs are arranged alternately. The outside-geared discs are connected to the coupling cage and the inside-geared discs are connected to the coupling hub in such a way that they cannot twist. The hub and the friction discs turn freely with the input shafts when the coupling is not actuated. When the travel range is shifted, oil is directed from the solenoid valve in the control valve block 15 through the appropriate duct to the coupling valve. As soon as the coupling valve is actuated, oil flows through the duct to the corresponding coupling piston. The oil pressure pushes the piston and discs against the press plate. When the steel and friction discs are pressed together, they connect the coupling cage and hub so that they turn together. When the coupling is closed, power is transmitted from the oil motor to the output shaft. The two drive shafts to the front and rear section are connected to the flanges of the output shaft 7 and 10. When the coupling is open, the return springs push the coupling piston back. The oil in front of the piston escapes through the coupling valve and holes in the coupling piston to the oil sump. The oil sump is fitted in transmission housing 1.
LBH/Version 01/10.2006/en/nk/30/01/2007
A pump fitted to the engine draws the gear oil is through pipes out of the sump. The oil strainer 8 is fitted on the intake port of the oil sump. The gear oil is pumped back through a filter into the transmission. Some of the oil is directed through the oil cooler. The cooled oil is pumped to the transmission lubrication system.

Selecting travel ranges When the electrical system is turned on, travel range A1-3 is automatically selected. The transmission remains in neutral until the parking brake is released and the travel direction is selected. Other travel ranges can be selected by pressing the “Shift Up” (1) or “Shift Down” (2) buttons on the control unit A11. The selected travel range is indicated on the display. The following travel ranges can be selected: A2 - 3
– Automatic travel range 2nd and 3rd gear

Gearshift strategy The controller constantly monitors the speed signals and the pump and motor positions, and selects the most suitable gear in the automatic travel ranges. The travel ranges can be changed at any speed. If the speed is too high for the new travel range, the controller slows the machine by changing the current to the pump and the variable displacement motor(s). When the speed is appropriate for the new travel range after hydrostatic braking, the travel range automatically changes. Control unit A14
Maximum speed Vmax If the task in hand required a reduced maximum speed, you can reduce the maximum speed by pressing the button 3. This function is only available when travelling forward in fixed gears 1 and 2. The current speed when the Vmax button is pressed is stored. The machine then reaches this speed at full throttle. If the Vmax button is pressed when the machine is not moving, the minimum speed for the gear is stored. – 1st gear approx. 4 km/h – 2nd gear approx. 10 km/h The Vmax function is deactivated when you press the Vmax button again or change the travel range.
LBH/Version 01/10.2006/en/nk/30/01/2007
If reverse travel direction is selected, the master shifts to automatic travel range A1-3 and the Vmax function is deactivated.

Kick-down The kick-down function allows manual shifting to first gear. Kick-down shifting is used in the following situations: – Slowing the machine down when approaching the pile. The kick-down function hydrostatically brakes the machine, and it shifts down to 1st gear. – Before driving onto a steep slope, you can use the kick-down function to shift to 1st gear. – When you select the travel direction, the machine drives off in 2nd gear. If steep terrain prevents this, you can use the kick-down function to shift straight to 1st gear. When you press the lick-down button 2 on the LIEBHERR control lever 1, the machine is automatically hydrostatically braked and is shifted down to 1st gear. At high travel speeds, the machine automatically shifts to 2nd gear, and then to 1st gear. – At low travel resistance, 1st gear remains selected for 10 seconds. During acceleration, the transmission automatically shifts to 2nd gear. – While pushing into the pile, first gear remains selected as long as the resistance is high. In kick-down mode, the maximum travel speed is 10 km/h. Kick-down mode can be deactivated early by pressing the travel direction switch 3.

Hydraulic control
The gear pump 7 draws up oil from the sump via a strainer. The oil sump is fitted in the transmission housing. The oil is pushed through the filter 8. The bypass valve 11 protects the filter from overload. This valve opens at a differential pressure of 4.5 bar. The hydro accumulator 9 is charged with gear oil. Some of the oil flows through the pressure reducing valve 15 to the four solenoid valves. The rest of the oil flows through the gear switching pressure relief valve 12 to the gear oil cooler 10. The pressure relief valve is set to 20±3 bar. The pressure relief valve is adjusted using discs. The operating pressure of the gearbox control unit is measured at the test point P. The pressure reducing valve 15 reduces the oil pressure for actuating the coupling valves from 20 to 9 bar. The bypass valve 14 protects the gear oil cooler from hydraulic overload. This opens at a differential pressure of 4 bar. Oil not used for lubricating the couplings flows through the lubricating oil pressure limiting valve 13 to the oil sump. The lubrication oil pressure limiting valve opens at 4 bar.

Function description Basic function The control valve block directs oil to the various consumers in the transmission. Some are hydrostatically controlled, others electrohydrostatically. The oil pressure, cooling and lubrication are hydraulically controlled. The couplings and the pressure modulation are electrohydraulically controlled. The solenoid valves receive control impulses from the main electronics (master). The solenoid valves open and direct the pressure oil to the valve of the actuated coupling and control the pressure modulation. Shifting gears
The illustration here shows the two modulation valves (the sectional view of the control valve block only shows one modulation valve). The modulation valve 2 for coupling 2 is held in place by the plug 1. Position 3 is the solenoid valve Y6.mo for the modulation. Component 4 is the modulation valve for coupling 1 and 3. Pressure modulation is required for smooth gear shifting. When a gear is selected, oil is directed to the corresponding coupling valve. The coupling valve is actuated and the oil flows unchecked through the modulation valve and the coupling valve into the coupling. This is called the rapid fill phase. During the rapid fill phase, the coupling pads should be quickly brought into contact, but without the coupling closing. This accelerates the shifting process. A few milliseconds after the solenoid valve shifts a gear, the modulation valve is energised and the oil is directed via a restrictor to the coupling. The oil flow to the coupling is metered, and the pressure in the coupling accumulates slowly and in a controlled manner. This is called the modulation phase.
The actuated variable displacement motor pivots to an angle of 0° with the required speed. The variable displacement motor is then set to the correct angle. The motor is synchronised before the torque is transferred, thus ensuring smooth shifting.

Shortly afterwards, the modulation valve is deactivated. The coupling pressure has now exceeded the force of the coupling springs and the coupling is closed.

These are the basic functions of the axle: – Increasing and transferring the drive torque – Transferring the vertical device forces to the wheels The gear output torque is transmitted via the drive shaft to the axle input shaft. The torque is increased to the wheel torque by the ratio of the tapered gear in the differential housing and that of the planetary drives in the wheel hubs. The input speed is reduced to the wheel speed accordingly. The vertical operating load of the machine is transmitted from the rear section via the screwed connection to the axle casing. The axle casing transmits this load to the wheel hubs so that the machine is supported by the wheels.

Speed balance of the left and right wheels When turning a corner, the left and right wheels cover different distances. The speeds of the two wheels are then different. The correct speed for each wheel is induced by the rolling condition.
The spreading force is generated by the transfer of the differential torque from the two pressure rings 6 to the compensation axles 7, which are loosely guided on diagonal surfaces. It produces a load-dependent locking torque in the disc brakes, which is always in equal proportion to the input torque. This ratio, expressed as a percentage, is called the locking value.
Self-locking function The disc brakes 9 on the left and right of the axle tapered gears 5 counteract the relative movement between the axle tapered gear 5 and the differential housing 3 with a braking force proportional to the rotary speed. This braking torque has a blocking action and increases the torque on the side with a firm hold on the ground. The braking torque thus compensates for the insufficient support from the side with poor hold. The disc brake consists of outer discs which are mounted in the differential housing and of non-twisting inner discs linked to the axle tapered gears.

The crown wheel drives the differential housing 3 and thus the four facing compensation tapered gears 8 of the differential. These rest on the tooth faces of the adjacent axle tapered gears 5 and thus drive the output shafts 4. The compensation tapered gears 8 have a balancing function and turn about their own axes to compensate for various wheel torques. The speed reduction of one wheel is compensated by the increased speed of the other wheel.

The service brake is a wet disc brake fitted in the wheel hubs. When pressure oil acts on the brake piston 3 the outer and inner discs 8 press against the limit stop of the ring gear 9. The inner discs mesh with the planetary carrier 10 so that they cannot slip. The outer discs mesh with the brake housing 2 and remain stationary. When the discs press together, the wheel torque is taken up by the brake housing. When it is not actuated, the brake piston 3 is held back by the return springs 5. The brake discs lose contact and the drag torque is minimised.
Wheel fastening The wheels are fastened onto the flanges of the wheel hubs by wheel nuts. They are centred by the spherical collar nuts.
Axle lubrication The axle has a shared oil system. This means the oil chambers in the differential and the wheel hubs are connected. Oil drain plugs are fitted on the wheel hubs and differential housing. LBH/Version 01/10.2006/en/nk/01/02/2007

The drive shaft transfers the torque from the transmission to the front axle. The universal joints at either end of the drive shaft allow it to compensate the angle between the drive and the power take-off. The angle needs to be compensated due to the articulated steering. The universal joint and connector tube can be displaced axially to mesh together. This compensates the length. Tolerances in assembly and slight movements during operation make this necessary.
Uniformity of torque transmission On drive shafts with simple universal joints, the connector tube between the two universal joints rotates unevenly. This is the case whenever the universal joint has to compensate for an angle. This occurrence is prevented by using a double cardan shaft. The connector tube turns evenly.

Function description Progressive lubrication The automatic central lubrication system is a progressive system. It lubricates progressively, i.e. all lubricating points in succession.
LBH/Version 01/10.2006/en/hd/30/01/2007
The main distributor is fitted with an inductive switch, which signals the lubrication cycles to the main electronics (master).
Overall system The electrically powered central lubrication pump pumps the grease to the main progressive distributor, which distributes it to the secondary progressive distributors. The secondary progressive distributors pump the grease to the lubrication points. The main electronics (master) control the lubrications cycles and pauses of the central lubrication pump.
Safety function – The pressure relief valve on the central lubrication pump monitors lubrication. If a lubrication point receives no grease from the distributor, the progressive distributor is blocked. The pressure in the central lubricating system increases. If the pressure rises above the permitted limit, grease escapes from the pressure relief valve. During this time, there are no impulses (lubrication cycles) for the main electronics (master).

Service Manual
Central lubrification system Automatic central lubrication system
Function description Pump action A DC motor 1 continually drives the cam 3 with a pressure ring 11. The cam raises and lowers the transfer piston 8. This provides the suction and pumping action of the transfer piston. The built-in check valve 9 prevents the pumped medium from being sucked back out of the main supply line. The agitator 6 pushes the lubricant out of the transparent reservoir 5 through a strainer 7 to the pump housing 2. This eliminates air bubbles in the grease.
Checking the grease quantity When all three LEDs on the central lubrication button light up, there is insufficient grease. This condition is reported by the level sensor. The reservoir is a transparent cylinder, in which the rubber stripper on the agitator can be seen. This allows you to check the grease level.
Filling The reservoir can be filled via the tapered grease fitting using a standard lubrication pump or via the rapid fill coupling using the grease gun.
Safety function The pressure relief valve 10, which is set to 280 bar, prevents excess pressure in the line system.
14.2.2
Progressive distributor MX-F Technical data See section 2.1
Design The progressive distributors are manufactured with variable discs. The advantage of this is that the distributors can be extended or reduced according to the number of lubrication points. The flow per stroke depends on the piston diameter. The progressive distributor needs at least three pumping elements in order to work properly.
LBH/Version 01/10.2006/en/hd/30/01/2007
The distributors must always be installed horizontally.

Function description Basic function
Piston positions of the progressive distributor MX-F A - C Piston positions
I - III Pistons
1 - 6 Grease duct outlets
The progressive distributors act hydraulically and distribute the lubricant in series to each outlet. The lubricant flows via the entrance of the distributor through all the distributor discs to the piston I (piston position A). The piston pushes to the left and presses the lubricant out of the left pressure chamber of the piston to the outlet 1 (piston position B). Pistons II and III then pump the lubricant to the outlets 2 and 3. After piston III moves, the lubricant flows to the left side of piston I (piston position C). The piston I pushes to the right and presses the lubricant out of the right pressure chamber of the piston to the outlet 4. Pistons II and III then pump the lubricant to the outlets 5 and 6. After piston II moves, the lubricant again flows to the right side of piston I (piston position A) and a new cycle of the progressive distributor begins. This function is repeated as long as lubricant is pumped to the distributor. Malfunctions Malfunctions can occur in the lubricant lines or inside the distributor. Malfunctions include: – Clogged lubricant lines – Twisted bearing casings These prevent the flow of lubricant, and thus block the distributors. LBH/Version 01/10.2006/en/hd/30/01/2007
When the distributor is blocked, lubricant flows out of the pressure relief valve on the central lubrication pump.

Function description How the heater works The heating and air conditioning control electronics (A21) are connected via CAN bus to the heating/air conditioning control unit. The heat exchanger is supplied with hot water from the engine cooling system. It is regulated using an electrically controlled water valve. The water valve controls the heating power. The intake air can be controlled using the fresh/recirculated air flap. The airflow is regulated using the various blower speed levels on the heating/ air conditioning system. When the air conditioning is in automatic mode, the speed levels are automatically controlled by the heating/air conditioning control electronics.
Flap control The driver can set the flaps manually as required, using the heating/air conditioning control unit. When the air conditioning is in automatic mode, the flaps are automatically controlled by the heating/air conditioning control electronics.

The air conditioning compressor 1 draws in the refrigerant in gas form and increases its energy level (pressure and thermal energy).
The cooled refrigerant liquefies. This change of state further reduces the energy in it. The refrigerant, which still has bubbles in it, passes into the dryer collector unit 6, where it is filtered and dried, and then, with the bubbles removed, through the rising pipe to the expansion valve 13 on the evaporator. The liquid, pressurised refrigerant is sprayed through the expansion valve 13 into the depressurised evaporator 11.

The heat thus generated is transferred to the condenser 3. The heat dissipation lowers the energy potential.
Service Manual
Cab, heating, air conditioning Air conditioning system
This allows the refrigerant to expand. The expansion reduces the pressure energy in the refrigerant and very quickly cools the evaporator. The evaporator 11 is exposed to hot air from the cab and transfers the heat to the refrigerant. This thermal exchange cools the cab air and heats the refrigerant. The heated refrigerant evaporates and turns to gas. This change of state requires additional energy from the (warm) evaporator, which further reduces the temperature.
Temperature regulation The temperature is regulated by the cyclical activation and deactivation of the magnetic coupling 2 of the air conditioning compressor during operation, or by mixing hot air from the heater, as for example in defrost mode. The frequency of switching is controlled by the temperature sensors in the evaporator and the program in the heating/air conditioning control electronics (see the technical data). The temperature is also regulated at the expansion valve. The pressure and temperature are recorded at the evaporator outlet and the injection quantity is precisely metered. These monitoring elements prevent the evaporator from icing up.

LBH/Version 01/03.2006/en/hd/30/01/2007
When the windows are misted up, the cab air must be dried. This is done by operating the air conditioning and the heater at the same time. The cab air can absorb more moisture when it is heated. The air flowing past the cool evaporator releases the moisture in the form of condensation.

Service Manual
Cab, heating, air conditioning Air conditioning system
Functions of the compressor oil There are the main functions of the compressor oil: – Reducing friction, wear and noise – Hydrostatic transmission of force to the various components of the air conditioning compressor – Dissipating heat – Increasing density – Lubricating the drive components (piston, shaft seal, bearing)
Magnetic coupling The pulley runs freely on the compressor shaft and is permanently driven by the V-ribbed belt. The power transmission between the pulley and the compressor shaft is controlled by a magnetic coupling 4. This is activated by the temperature switch in the evaporator or the pressure switch on the dryer collector unit. By periodic activation of the compressor, the evaporator is kept at a temperature of between +1 °C (uncoupling) and +4 °C (coupling), this preventing the air conditioning unit from icing up. If the pressure rises above 24 bar or below 2 bar on the pressure side of the compressor, it is also uncoupled.

Sight glass
Sight glass 1 White filling level bead
2 Orange moisture indicator bead
The sight glass is located in the upper third of the dryer collector unit. The sight glass has the following purposes: – Checking when filling the system – Checking the refrigerant level during operation – Checking the moisture content of the refrigerant – Checking contamination of the refrigerant circuit Sight glass functions
Checking when filling the system – When completely filling the system, it is necessary to top up with gaseous refrigerant on the intake side when the system is switched on. When doing this, watch the level indicator bead 1 in the sight glass. As soon as it floats on the refrigerant to the top of the sight glass, stop adding refrigerant. Checking the refrigerant level during operation – Once the system has been running for about five minutes (to allow the refrigerant to distribute), the white level indicator bead should be near the top of the sight glass. As the engine speed increases, the level rises slightly. The refrigerant should flow through the sight glass with no visible bubbles during operation. If gas bubbles appear, it is normally due to insufficient refrigerant in the system. Sometimes the refrigerant is not sufficiently condensed due to insufficient heat extraction at the condenser (contamination), which can result in bubbles in the sight glass. Checking the moisture content of the refrigerant – There is a small orange indicator bead 2 in the sight glass. If it turns light grey, there is too much moisture in the system.
LBH/Version 01/03.2006/en/hd/30/01/2007
In this case the system must be completely drained and evacuated. The oil in the compressor must also be replaced. The entire dryer collector unit must be replaced too. Checking contamination of the refrigerant circuit – A sudden change of colour in the sight glass indicates a problem in the system. A change in colour is normally caused by overheating in the refrigerant circuit. This is normally due to internal or external contamination.

2 Dryer collector unit
The pressure switch is attached to the dryer collector unit in the air conditioning circuit.
Function description Basic function The pressure switch monitors the pressure in the cooling circuit. It deactivates the magnetic coupling and therefore the compressor if the pressure is too low or too high. This prevents the compressor from running dry if there is too little refrigerant (insufficient pressure).
Excess pressure may be caused by: – Too much refrigerant in the circuit – Excess temperature due to a dirty condenser or defective fan control – The filter in the dryer collector unit may be very dirty – The expansion valve may be iced up (too much moisture in the refrigerant) or dirty (blocked).

LBH/Version 01/03.2006/en/hd/30/01/2007
The pressurised refrigerant, which is cooled and liquefied by the condenser, is sprayed through the expansion valve 2 into the evaporator 4, where there is a vacuum. The drop in pressure allows the refrigerant to expand. The expansion causes a great drop in the thermal energy. The refrigerant is cooled. The thermal energy taken from the cab air via the fins on the evaporator 4 evaporates the refrigerant.

Function description Basic function The bucket base and bushings are protected from corrosive or abrasive material by a special radial sealing ring. If this material penetrates the bearing it can increase wear and enlarge the play. If the bearing is loose, the friction will cause increased wear despite lubrication. The radial seal is installed on both sides of the bushing between the bucket arm and bearing plates. The radial seal is held in place by the bearing pin. The steel ring is positioned parallel to the contact faces of the bucket arm and bearing plate and prevents the lip seal ring from being damaged by the forces acting on the bucket bearing. Axial clearance between the bearing journals of the bucket arm and the bearing plate ensures that the bearing moves smoothly and is perfectly sealed.

Removing the pin bearings Design
Extractor hammer
LBH/Version 02/10.2006/en/nk/01/02/2007
There are many ways to remove a pin. One tried-and-tested method is to use the extractor hammer shown above. The tool is easy to make and the pin is not damaged when removed. The extractor hammer consists of a round rod with an M36 thread on both ends, two machined faces for an open-ended wrench, the hammer head and two nuts. The first nut has a flange to prevent damage to the nuts.
Procedure • Put the machine in maintenance position 1. • Screw the round rod into the extractor thread of the pin. • Push the hammer onto the rod and tighten the nuts. • Remove the retaining screw. • Knock out the pin.

17.2.4 Welding processes
Changing the bushings This section describes how to change the bushings on the bucket bearing. The method for other bearings is similar.
Procedure • Put the machine in maintenance position 1. • Remove the pin as described in 17.2.3. • Start the machine and drive in reverse. • Drive the machine to a suitable place for repairs. • Slightly raise the lift arms and securely support them. • Switch off the engine and pull out the key. • Turn off the battery main switch. To make it easier to remove the steel bucket bushings, we recommend welding several lengthways seams around the bushing. The advantage of this is that when the bushing cools down it becomes smaller in diameter and thus easier to push out of the hole. • Perform the welding in accordance with the safety instructions for welding on the machine (see the operating manual). • Attach the earth lead of the welding equipment as close as possible to the welding position. • Weld on the inside of the bushing. Leave a distance of 10 mm between the ends of the bushing and the welds (see illustration).
LBH/Version 02/10.2006/en/nk/01/02/2007
• Let the bushing cool down after welding.
