Transmissions DIWA.2, DIWA.3, DIWA.3E

Monthly Check oil level 

Bring the transmission to operating temperature, i.e. the oil temperature must then be at least 60 °C ( = 140 °F). Note! The transmission oil temperature is about the same as the cooling water temperature. The the cooling water temperature indicator can therefore be used for determining transmission oil temperature.



Place the vehicle in horizontal position.

Danger! Apply the parking brake before carrying out further maintenance work on the bus, so that the vehicle cannot move on its own!

 

Press the N key and thus bring the transmission to its neutral position. Start the engine and let it run at idle speed.



Withdraw the dipstick from its guide tube and clean it.



Insert the dipstick again briefly to prevent wrong oil level reading by splash oil.



Read the oil level. The two nominal marks max. and min. are important. The difference in quantity between "min." and "max." is about 2.5 l. Note!

Too little oil:

Transmission malfunction. Consequence: e.g. disk damage! Too much oil: Consequences: e.g. higher fuel consumption, oil escapes at the breather!

Note! For silumin heat exchangers: Only use anti-freeze and/or anti-corrosive agents in the cooling water which do not attack light metal (see also "Technical Manuals").

With oil grades according to List of Lubricants 55.6335. ..* (G 607): every 60 000 km, at leas t every 2 years , however. With oil grad es according to Lis t of Lubric ants 55.6336. ..* (G 1363): every 120 000 km, at lea st every 3 yea rs, however.

Change oil and oil filter for DIWA.2, DIWA.3 Note!

Drain oil at operating temperature only!

Danger! Scalding by hot oil! 1



Stop the engine.



Remove the drain plug (1) for the oil in the oil pan (allen wrench 12 mm) and drain the oil.



Remove the drain plug (2) for the converter oil and drain the oil. The plug is accessible through the oil pan drain hole.



Install drain plugs with new copper seals. Tighten drain plug (2) to 50 Nm and drain plug (1) to 120 Nm.

Voith. Fault Finding DIWA.3, DIWA.3E

Procedure for finding faults in DIWA.3 and DIWA.3E transmissions If transmission malfunctions occur, fault may be present in a) the control unit records, b) in the electrical or c) mechanical part of electromechanical or d) purely mechanical components. In the case of faults in a) and b), use of "Diagnostic Manual" and "Trouble Shooting", if required, alone may be sufficient for repair. However, since malfunctions in c) and d) are not detected by the control or diagnosis, it is recommended to refer to the appropriate Voith documentation and programs for transmission malfunction repairs in the following order, for example: Read out the fault memory of the transmission control unit by means of the diagnostic program DIWAGNOSIS:

Diagnostic Manual

Analysis of malfunctions and list of remedies, including, perhaps, information about transmission design and operation in the "Technical Manuals" and "Technical Descriptions with Oil Control Diagrams" for DIWA.3 and DIWA.3E:

Differences concerning the symptoms of transmission malfunctions in DIWA.3E and DIWA.3 In general, the symptoms are similar for both transmission variants. The statements below therefore apply to both variants unless otherwise indicated. 1. A major difference between DIWA.3E and DIWA.3 transmissions is the converter filling control (CFC) which does not exist in DIWA.3. The purpose of converter inlet control is to improve application of the converter brake also at high vehicle speeds in 4th (and perhaps also 3rd) gear. Among other things, the hydraulic control includes two new valves: a converter inlet valve and a breather valve. The converter drain valve has been modified. Other parts, such as the turbine accumulator, have been dispensed with. Differences regarding the symptoms of transmission malfunctions can therefore be found in the chapters describing converter operation, i. e. the first gear (DIWA drive range), the reverse gear, and braking with the converter.

   First check in case of faults 

By means of the Voith diagnostic program. Its use is described in the Diagnostic Manual.

Continued operation possible, 

wf the transmission does no longer shift to 2nd, 3rd or 4th gear, but operation in 1st gear is normal. Causes: – failure of the inductive pick-up, – cable break or short.

Emergency operation possible 

by means of emergency control cable in 1st gear. Always note that connection of the cable will engage 1st gear. Therefore:

Danger! Apply the parking brake when the bus is stopped to prevent that the vehicle can move unintentionally!

Towing Note! In order to prevent damage to the DIWA transmission when the vehicle is towed, the following must be observed: 

Set the transmission to neutral and screw off plug from the transmission or electronic control unit.



In case of transmission damage: remove cardan shaft or stub shaft of rear axle.



If there is no transmission damage the vehicle can be towed with the cardan shaft installed, yet only up to a distance of 10 km. The maximum towing speed is 30 km/h.

Operating pr essure

The uniform nominal value for the operating pressure is: pA = 8.5 bar (tolerance ± 0.2 bar). Measure the pressure only at an oil temperature of 80 - 90 °C (= 176 - 194 °F), immediately after shifting to 2nd gear (engine speed approx. 1500 rpm). Nominal value at idle speed (n



approx. 500 - 600 rpm) pA



3.5 bar.

Measuring points The operating is point usually measured at thepressure measuring (figure 1/1).

1

If a measuring cover (figs. 2 and 3) is used, pressures which must correspond to the operating pressure are measured at the measuring points for the clutches resp. brakes DK, EK, PB, WP and SK. Fig. 2: Meas. points for DIWA.3 Fig. 3: Meas. points for DIWA.3E 2

Note! The WR oil pressure is cycled and therefore variable over time, its amount in addition depending on the relevant operating state (during braking or reversing). Therefore, simple pressure measurements by means of pressure gauges are not adequate for more thorough troubleshooting. 3

The measuring points TB, RBG and RBK are each pressurized with the higher operating or converter pressure. Exceptions: The RBK pressure is set to 1. approx. 2.5 bar for converter pressure reduction WDA, 2. max. approx. 2 bar for braking in 1st gear range (chapters 5.4 and 5.6).

  

Danger! Connect pressure gauge, or change measuring cover, only with the engine stopped, otherwise hot oil may result in scalding!

Voith. Fault Finding DIWA.3, DIWA.3E

If the measuring points mentioned are not accessible, the operating pressure can also be measured for DIWA.3 transmissions at the intermediate flange (if installed) of the oil filter: If the pressure is measured before (4/1) or after (4/2) the filter, approx. 0.5 bar must be added as flow resistance to obtain the value for the operating pressure. Note! Only measure before the fil-

ter if the filter element is clean! The working pressure can be set at the threaded pin of the operating pressure valve (5/1) - only possible with special screwdriver and socket wrench through the oil filler!

Engine idle speed

In particular in conjunction with electronic engine control units, it is frequently not possible to set the idle speed n in a simple manner. In addition, the settings are systemdependent (guideline: n ≥ approx. 500 - 600 rpm with warm engine). On the other hand, the idle speed must not be too high, because the input clutch, for example, will not close: n ≤ 850 rpm (for gas engine: n ≤ 1000 rpm ).

  

During a function check, the speed can be measured by means of the diagnostic program, for example. Note! If the idle speed must be changed, contact th e bus manufacturer, if required.

9.2

Test: load transmitter signals as function of accelerator pedal position

The life of DIWA transmissions to a considerable extent depends on proper pressures in front of the disk clutches and brakes during shifting. Along with the input and output speeds, the motor torque is important, which to a great extent is in turn affected by the accelerator pedal position resp. the appropriate load levels L0 - L6 (or L0 - L7). The associated electronic signals are provided to the transmission in a different manner dependent on the engine control system.

     

The following settings can be checked in a relatively simple manner with the bus stopped by means of the diagnostic program:

  

1. Load level L0 = "idle", acc elerator pedal completely released. 2. Load level L6 = "full load", accele rator depressed to the stop (firs t, if any). Depen dent on the bus design, this accelerator pedal position may also be defined as L7 = "kickdown", which is indicated by the diagnostic system. 3. Inf installed: load level L7 = "kickd own", accelerator pedal depressed bey ond the first and to the end stop against greater resistance. 4. Gradually depress the accelerator pedal from idl e to full load and check tha t the "partial load" signals L2 to L5 are also displayed by the diagnostic system. Note! For an accurate check of the load transmitter partial load signals as function of the accelerator pedal travel, documents from the bus manufacturer are required.

  

Danger! When settings are made with the bus stopped, apply the parking brake to prevent unintended rolling of the vehicle! If the diagnostic system indicates load levels that do not correspond to the accelerator pedal position, the following causes for faults may exist, apart from cable and connector defects: 1. Setting of accelerator pedal stops (idl e, full load, kick down, if installed). 2. With a VDO or Voith lo ad transmitter: connection between load transmitter and injection pump, see figures 7 and 8 on next page. 3. With electronic engine control units: conn ection between accelerator pedal and load transmitter (setpoint switch), see figure 9 on next page. 4. Wrong control unit with data of the wron g load transmitter type (indicated by diagnostic system).

Otherwise, move the fastening with the link accordingly. Then recheck the setting in 0 load position! Note! the adjustment angles of the levers of injection pump and load transmitter must be in proportion to each other! For example, if the injection pump lever is moved by 1/3 of the angle between 0 and full load, the load transmitter lever must also be move by 1/3 of its angle between 0 and full load!

Test: rated engine torque as function of load stage or engine speed

It may be necessary to determine the maximum possible engine torques in bus operation. Indirectly, they can be determined in a relatively simple manner by speed measurements in the so-called stall point - e.g. by means of the diagnostic program.

  

First of all pay attention: Danger! Apply parking brake to prevent unintentional bus movement! After that as example for full load operation (= load level L6): 1. engage forward gear, 2. depress accelerator pedal to the full load stop, 3. enter the measured engine speed N1 (= st all speed) in the diagram bel ow (figure 10). The intersection with the appropriate pump characteristic of the transmission - for pump design, check the transmission nameplate, for example shows the maximum possible engine torque with the bus stopped. Note! The latter torque may deviate significantly from the maximum possible engine torque while driving with electronic engine control units. These tests are performed during acceptance protocol measurements.

SAFETY NOTICE

GENERAL

Companies repairing ZF units are responsible for their own work safety.

Read this manual carefully before starting any tests or repair work.

To avoid injury to personnel and damage to products, all safety regulations and legal requirements which apply to repair and maintenance work must be adhered to. Before starting work, mechanics must familiarize themselves with these regulations.

Personnel required to carry out repairs on ZF products must receive appropriate training in advance. It is the responsibility of each company to ensure that their repair staff is properly trained.

The following safety instructions appear in this manual:

CAUTION Pictures, drawings and components do not always represent the srcinal object, but are used to illustrate working procedures. Pictures, drawings and components are not to scale. Conclusions about size and weight should not be drawn (even within a complete illustration). Always follow the working steps as described in the text.

After completion of repair work and testing, skilled staff must satisfy themselves that the product is functioning correctly.



NOTE Refers to special processes, techniques, data, use of auxiliary equipment, etc.

CAUTION This is used when incorrect, unprofessional working practices could damage the product.

 DANGER This is used when lack of care could lead to personal injury or death.

INFORMA TION

THREATS TO THE ENVIRONMENT !

Lubricants agents not system. be allowed to enter the and soil,cleaning ground w ater ormust sewage • Ask your local environment agency for safety information on the relevant products and adhere to their requirements. • Collect used oil in a suitably large container. • Dispose of used oil, dirty fil ters, lubricants and cleaning agents in accordance with environmental protection guidelines. • When working with lubricants and cleaning agents always refer to the manufacturer’s instructions.

CAUTION The transmission must NOT be hung by the input shaft NOR by the output flange.

6

HP502C/HP592C/HP602C In case of doubt always turn to the relevant department within ZF After-Sales Services for advice. All work on transmissions is to be performed expertly and under clean conditions. Use specified tools to dismantle and assemble transmissions.

After removing the transmission from the vehicle, clean thoroughly with a suitable cleaning agent before opening. Pay particular attention to the projections and recesses of housings and covers when cleaning. Parts joined with Loctite are easier to separate if warmed with a fan heater.

Instructionsforrepairs GASKET S, LOCKING P LA TES

Parts which cannot be removed without being damaged must always be replaced with new parts (e.g. gaskets and locking plates).

SHAFT SEALS

Always change shaft seals with rough, ripped or hardened packing washers. Seal contact surfaces must be totally clean and in perfect condition.

REWORKING CLEAN ING P ARTS

Remove remains of old gaskets on all seal-faces. Carefully remove burrs or similar patches of roughness using an oil-stone.

Lube bores and grooves must be free of anti-corrosion agents and foreign matter; check for perfect passage. Carefully cover opened transmissions to prevent foreign matter from entering.

Rework may be carried out on seal contact surfaces using plunge-cut grinding only, never use an emery cloth. Ensure that there are no traces of grinding or riffling.

Parts such as ball or roller bearings, multi-discs, thrust washers etc., must be inspected by a competent person, who should decide whether or not they can be re-used. Replace parts which are damaged or have suffered from excessive wear.

Find a clean site to assemble the transmission. Gaskets are installed without the use of sealing compound or grease. When measuring silicon-coated gaskets, take care not to include the silicon layer in the measurement. During assembly, comply with all adjustment data, checking data and tightening torques in the Repair Manual.

Instructions for carrying out repairs BEARINGS

If bearings are mounted in heated condition, they are to be heated evenly (e.g. heating cabinet). Temperature should be at ca. 85 °C and must not exceed 120 °C. Each mounted bearing must be oiled with operating oil.

SEALING

If a specific sealing agent* is to be used for sealing, comply with the manufacturer’s directions for use. Apply a thin layer of sealing agent to the surfaces and spread evenly. Do not allow sealing to enter oil ducts and bores. On oil-carrying ducts and bores, wipe off the sealing agent on the surfaces to be sealed near apertures to ensure that no sealing agent enters the oil feeds when the surfaces are sealed.

H P 5 0 2 C / H P 5 9 2 C / HP 6 0 2 C d) Dual shaft seals have two sealing lips. The dust-proof sealing lip (X) must face outwards. 

e) Fill the gap between the sealing lips so it is 60% filled with grease (e.g. produced by Aral such as Aralub HL2 or by DEA such as Spectron FO 20). f) If possible, heat shaft seal bores to between 40 and 50 °C (makes fitting easier). Press the seal shaft with mounting or faceplate onto the relevant installation depth plan.

RETAINING AGENTS

Retaining agents* may only be used in places as specified in the parts list. Always comply with manufacturer’s directions for use when using retaining agents (e.g. Loctite). During assembly, withtorques. all adjustment data, checking data andcomply tightening

SHAFT SEALS

a) Apply a light coat of sealing agent* on outer edge of shaft seals with “steel surround”. TRANSMISSION OIL

b) Never apply sealing agentto shaft seals with “rubber surround”, but apply a thin coat of Vaseline 8420 to the outer edge or wet with a lubricant, e.g. a water-soluble, concentrated washing-up liquid (e.g. Pril, Coin, Palmolive). c) Shaft seals with steel and rubber surrounds should be treated on the outer edge of the rubber surround as described above in section b).

After completing repairs, fill transmissions with transmission oil. For the procedure and approved oils, refer to the transmission operating manual and List of Lubricants TE-ML (refer to identification plate) which are available from any ZF After-Sales Service Point. After filling the transmission with oil, tighten the screw plugs at the oil filling point and the oil overflow to the specified torques.

The DPA 04 I features three interfaces, V-24, RS 232, ISO 9141 and SAE J1708. • The RS 232 communicates between the DPA 04 I and a laptop computer. • The ISO 9141 and SAE J1708 communicate between the DPA 04 I and the control unit. Appropriate adapter cables are required for the ISO and the SAE interfaces. The same adapter cables as the DPA 02/03 can be used (pins compatible with the ISO interface).

NOTE: In SAE mode, dependent upon switch setting “KL15ECU”

Here are the three basic operating modes of the DPA 04 I: 4. 1.

Data transmission via ISO interface and control unit.

2.

Data transmission via SAE interface and control unit.

Do not use high pressure when lubricating the lubrication The grease gun must be used evenlypoints. and smoothly. The drive shaft’s slip joint must not be cleaned using a high pressure hose or steam. If in doubt, the drive shaft should be lubricated after it has been cleaned. If no grease appears to escape from one or more bearings when lubricating the lubrication points, then the relevant spider must be replaced together with the bearings. The drive flanges on a new drive shaft have a protective coating. If this coating does not have any dirt on it, then it does not have to be removed before assembly. The drive flanges should be free of dirt before assembly. Only use a lubricant that satisfies the specifications given. Do not use any lubricant



that contains Mos2. treatment, the slip joint During anti-corrosion must be completely covered.

1.2 SERVICE The drive shaft should be inspected according to the intervals below. Service intervals: There should be a small service every 50,000 km or every six months. There should be a large service every 200,000 km or every two years.



1.2.1 Small service 1. Inspect all the joints. Where necessary, retighten the nuts and bolts using a torqu e spanner. 2.

Check whether all the circlips are still in place and are fitted correctly.

3.

Check whether the bearing/coupling components show signs of heating (discolouring of the material or burnt sealing rings).

4.

Check the O-rings on the bearing bushes and the slip joint visually and by seeing how much lubricant has been used.

5.

Check whether the grease nipples are still present. Check their condition.

6.

Check the visible plastic guide coating on the slip joint for damage.

7.

Check the drive shaft for rust, distortion and other damage.

8.

If there is excessive noise or vibrations when driving at a certain speed, check the balance plates on the drive shaft (unbalance).

9.

Check whether any play can be felt or seen by pulling the drive shaft and slip joint upwards.

1.2.2 Large service 1. Carry out the inspection given for the “small service”. 2.

Remove the drive shaft (see “Drive shaft removal and installation”).

3.

Check the play on the universal joint bearings by laying the drive shaft flat on a table. Next, put one hand on the pipe of t he drive shaft axle and, with the other hand, rotate the drive flange. No play must be felt. Do this for bo th sides. Bear in mind that the slip joint can extend out a bit. If play can be felt, the spider and the bearings must be replaced (see “Spider removal and installation”).

By hand, check the movement of t he drive flanges. It must be possible to turn the drive flanges in a horizontal and vertical direction without any resistance (jarring) being felt. The drive flanges must not drop by themselves. If resistance can be felt, then the bearings must first be lubricated. If this doe s not have any effect, then the bearings and the spider must be replaced (see “Spider removal and installation”).

5.

Clean all the grease nipples and lubricate all the points.



Use a suitable lubricant (see “Technical information”). MoS2 grease must not be used.

Check whether lubricant escapes from all the universal joint’s bearings. If this does not happen, then one or more of the bearings are faulty. Replace the relevant spider and its bearings (see “Spider removal and installation”).

Check for tangential play (play between the teeth). Secure the slip joint’s fixed pipe in a workbench with the yoke in a vertical direction. Place a suitable gauge indicator on a flat part and allow the measuring pin to rest against the side of the yoke. Zero the gauge. Turn the yoke tangentially and measure the play on the splines. This must not be greater than 0.2 mm.

Check the slip joint’s radial play. Pull the slip joint out about 45 mm. Lay the drive shaft on a flat table with the fixed yokes touching the table. Place a su itable gauge indicator with a magnetic foot just behind the weld on the drive shaft’s pipe. Put the measuring pin just behind the weld on the yoke and zero the gauge. Lift the drive shaft up a little bit in the middle whilst making sure that the yokes remain touching the table. Check the play. It must not be greater than 0.17 mm.

The drive shaft must be replaced completely if the radial or tangential play is too large.

General

Check the slip joint’s splines. Remove the grease nipple. Mark the position of both parts of the slip joint in relation to each oth er. Carefully pull the slip joint apart. Check the innermost and outermost splines for damage, signs of heating and wear. Check the O-ring for damage. If there are any faults, replace the O-ring or the complete drive shaft. If there is no damage, lubricate the O-ring and slip joint and push them together (beware of the alignment!). Fit the grease nipple and lubricate the slip joint.



Use a suitable lubricant (see “Technical information”). MoS2 grease must not be used.

The drive shaft has components that could trap body parts. Always move and store the drive shaft in a horizontal position. This will prevent damage which would make the drive shaft become unbalanced.



Only use srcinal bolts that are of the correct type. Removal 1. Support the shaft in at l east two places. 2.

Remove thepush fixing bolts from the flanges. necessary, the drive shaft’s slip jointIf inwards a bit, so that the drive shaft can easily be reached between the rear axle and the gear box.

3.

Remove the drive shaft from underneath the vehicle. The drive shaft must always be moved and stored in a horizontal position.

4.

When repairs have been carried out, or another drive shaft has been fitted, the yokes must be in line and all the universal joints must be lubricated.

Installation 1.

Fit the drive shaft in the reverse order to its removal. Tighten all the bolts to the required torque (see “Technical information”).

2.3 SPIDER Removal 1. Remove the complete drive shaft. See “Drive shaft removal and installation”. 2.

Place the drive shaft on a strong, flat table using a bench vice.

3.

Remove all the circlips and grease nipples and throw them away.

4.

Mark both parts of the slip joint so that they can be put back in the correct way during assembly.

5.

Put the shaft on a bush under a press as shown (the inner diameter of the bush must be greater than the diameter of the bearing bush). Push the spider downwards, together with the bearings and flange, using a suitable punch until the spider touches the axle’s yoke.

6.

Remove the drive shaft from under the press and clamp the part of the bearing bush that has been pushed out in a bench vice.

7.

Work the yoke upwards using a tyre lever. This will make the bearing bush come completely loose so that it can be removed.
