* = dependent on Vehicle type and application ** = dependent on the Transmission version Description: The ZF-Transmissions 4 WG-190/210 are composed of a hydrodynamic torque converter and a rear-mounted multi-speed powershift transmission with integrated transfer case (see Table- 1).

The torque converter is a wear-free starting device which is infinitely variable adapting itself to the required situations (necessary input torque).

Input by direct mounting via diaphragm on the engine, or separate installation (input via universal shaft) with DIN-, Mechanic- or Spicer-input flange.

The transmission can be shifted manually or fully-automatically by means of the Electronic unit EST-37.

Torque converter: Unit size W 300 and 340 with torque multiplication.

Powershift transmission: 4 Forward speeds and 3 Reverse speeds.

Output: The powershift transmission has between input and output shaft a center distance of 540 mm, and can be equipped with the following components: - with output flanges to the front and rear axle for different universal shafts - on the rear output (rear-side) with a disk brake as parking brake - on the converter side with axle disconnection.

Power take-off: For the drive of an external oil pressure pump, an engine-dependent, coaxial power take-off is planned.

It allows the attachment of pumps with „SAE-B and C“ Connection.

If desired engine dependent power take-off are available also up to 2.

IMPORTANT INSTRUCTIONS Oil level check (see 4.2): In the cold start phase, the engine must be running about 2 – 3 minutes at idling speed and the marking on the oil dipstick must then be lying above the cold start mark. The oil level check in the transmission must be carried out at engine idling speed and operating temperature of the transmission (80° to 90° C).

At stationary engine, the oil level in the transmission is rising essentially, according to the installation conditions !

At every oil change, the ZF-Fine filter must be exchanged. In addition, ZF recommends to start the autonomous calibration of the shifting elements (AEB).

The independent calibration of the shifting elements (AEB) must be started after the initial installation of the transmission and the Electronics in the vehicle at the Vehicle Manufacturer and after every replacement of the transmission, the electrohydraulic control or the TCU in case of a failure.

Put the Controller at the starting of the engine always to the Neutral position.

At running engine and transmission in Neutral, the parking brake must be engaged or the service brake be actuated, to prevent the vehicle from rolling.

Prior to every start off, loosen the parking brake.

The engagement of the speed out of Neutral is only possible under the programmed transmission input speed (turbine speed).

Neutral position of the selector switch at higher vehicle speeds (above stepping speed) s not admissible.

Either a suitable gear is to be shifted immediately, or the vehicle must be stopped at once.

Reversing (Standard): In the speeds, released for the direct reversing, as a rule in the speeds 1 F ⇔ 1 R and 2 F ⇔ 2 R , it is possible to reverse directly at any time. Reversings in the speeds 3 and 4 are realized dependent on the driving speed, the permitted reversing speed is then normally the maximum speed of the 2nd speed.

- Beyond the programmed reversing limit, the vehicle will be braked down by the Electronic unit EST-37 by downshiftings, and only then the reversing is carried out into the correspondingly preselected gear.

- Below the permitted speed, the reversing will be carried out.

The programming is customized and can therefore be different from the standard. Therefore, the exact procedure must be taken from the Operating Instructions of the respective Vehicle Manufacturer !

9

ERGOPOWER

Geschäftsbereich Arbeitsmaschinen-Antriebe und Achssysteme

At stopped engine, there is on the Controller, despite a preselected gear, no power flow between transmission and engine, i.e. the transmission is in the idling position.

The parking brake must therefore be completely actuated !

When leaving the vehicle, secure it additionally by brake blocks !

The towing speed must in no case be higher than 10 km/h, the towing distance not longer than 10 km.

It is imperative to observe this Specification because otherwise the transmission will be damaged due to insufficient oil supply !

At a longer distance, the best solution would be to transport the defective vehicle with a Low loader.

Operating temperature behind the converter at least 65° and 100° C in continuous operation, a short-time increase up to max. 120° C is permitted.

Temperature in the sump 60° - 90° C. In case of irregularities on the transmission, put the vehicle out of service and ask for Specialists.

Protective measures for the ZF-Electronics at electrical operations on the vehicle: At the following operations, the ignition must be switched off and the control unit plug must be pulled off from the ZF-Electronics: ∗ At any kind of electrical operations on the vehicle. ∗ At welding operations on the vehicle. ∗ At insulation tests on the electric system.

The converter is working according to the Trilok-System, i.e. it assumes at high turbine speed the characteristics, and with it the favourable efficiency of a fluid clutch.

The converter is designed according to the engine power so that the most favourable operating conditions are obtained for each installation case.

The Torque converter is composed of 3 main components: Impeller – Turbine wheel – Stator (Reaction member) These 3 impellers are arranged in such a ring-shaped system that the fluid is streaming through the circuit components in the indicated order.

Pressure oil from the transmission pump is constantly streaming through the converter. In this way, the converter can fulfill its task to multiply the torque of the engine and at the same time, the heat created in the converter is dissipated via the escaping oil.

The oil which is streaming out of the impeller, enters the turbine wheel and is there reversed in the direction of flow.

According to the rate of reversion, the turbine wheel and with it also the output shaft is receiving a more or less high reaction torque.

The stator (reaction member), following the turbine, has the task to reverse the oil streaming out of the turbine once more and to deliver it under the suitable discharge direction to the impeller.

11

ERGOPOWER

Geschäftsbereich Arbeitsmaschinen-Antriebe und Achssysteme

Due to the reversion, the stator is receiving a reaction torque.

The relation turbine torque/pump torque is called torque multiplication. This is the higher, the greater the speed difference of impeller and turbine wheel will be.

Therefore, the maximum torque multiplication is created at stationary turbine wheel.

With increasing output speed, the torque multiplication is decreasing. The adaption of the output speed to a certain required output torque will be infinitely variable and automatically achieved by the torque converter.

When the turbine speed is reaching about 80% of the pump speed, the torque multiplication becomes 1,0 i.e. the turbine torque becomes equal to that of the pump torque.

From this point on, the converter is working similar to a fluid clutch.

A stator freewheel serves to improve the efficiency in the upper driving range, in the torque multiplication range it is backing-up the torque upon the housing, and is released in the clutch range.

In this way, the stator can rotate freely.

1.2 Powershift transmission: The multi-speed reversing transmission in countershaft design is power shiftable by hydraulically actuated multi-disk clutches.

All gears are constantly meshing and carried on antifriction bearings.

The gear wheels, bearings and clutches are cooled and lubricated with oil.

The 4-speed reversing transmission is equipped with 6 multi-disk clutches.

At the shifting, the actual plate pack is compressed by a piston, movable in axial direction, which is pressurized by pressure oil.

A compression spring takes over the pushing back of the piston, thus the release of the plate pack. As to the layout of the transmission as well as the specifications of the closed clutches in the single speeds, see Table-1, 7 and 8.

1.3 Transmission control: Transmission control, see Schedule of measuring points, Oil circuit diagram ans Electro- hydraulic control unit see Table-7, 8 and 9.

The transmission pump, necessary for the oil supply of the converter, and for the transmission control, is sitting in the transmission on the engine-dependent input shaft.

The feed rate of the pump is Q = 105 l/min, at nEngine = 2000 min-1.

This pump is sucking the oil via the coarse filter out of the oil sump and delivers it via the ZFFine filter – the filter can also be fitted externally from the transmission – to the main pressure valve.

If because of contamination, resp. damage, the through-flow through the ZF-Fine filter is not ensured, the oil will be directly conducted via a filter differential pressure valve (bypass valve ∆p= 5,5 bar to the lubrication.

In this case, an error indication is shown on the ZF-Display.

The six clutches of the transmission are selected via the 6 proportional valves P1 to P6.

The proportional valve (pressure regulator unit) is composed of pressure regulator (e.g. Y6), follow-on slide and vibration damper.

The control pressure of 9 bar for the actuation of the follow-on slides is created by the pressure reducing valve. The pressure oil (16+2 bar) is directed via the follow-on slide to the respective clutch.

Due to the direct proportional selection with separated pressure modulation for each clutch, the pressures to the clutches, which are engaged in the gear change, will be controlled. In this way, a hydraulic intersection of the clutches to be engaged and disengaged becomes possible.

This is creating spontaneous shiftings without traction force interruption.

At the shifting, the following criteria will be considered: -

Speed of engine, turbine, central gear train and output.

Transmission temperature.

Shifting mode (up-, down-, reverse shifting and speed engagement out of Neutral).

Load condition (full and part load, traction, overrun inclusive consideration of load cycles during the shifting).

The main pressure valve is limiting the max. control pressure to 16+2 bar and releases the main stream to the converter and lubricating circuit.

In the inlet to the converter, a converter safety valve is installed which protects the converter from high internal pressures (opening pressure 11,0 bar).

Within the converter, the oil serves to transmit the power according to the well-known hydrodynamic principle (see Chapter Torque converter 1.1).

To avoid cavitation, the converter must be always completely filled with oil.

This is achieved by a converter pressure back-up valve, rear-mounted to the converter, with an opening pressure of at least 4,3 bar.

The oil, escaping out of the converter, is directed to a heat exchanger.

The selection and definition of the heat exchanger must be carried out according to our Installation specification for hydrodynamic powershift transmissions by the Customer on his own responsibility.

The heat exchanger is not within the scope of supply of the ZF Passau GmbH. From the heat exchanger, the oil is directed to the transmission and there to the lubricating oil circuit, so that all lubricating points are supplied with cooled oil.

In the Electrohydraulic control unit are 6 pressure regulators installed – see Table-9.

The allocation of the pressure regulators to the single speeds can be seen on the Tables 7 and 8.

The installation of the TCU must be realized on a protected point in the cabin.

An overfloating with water must be excluded. Besides, the penetration of water via the plug connection must be prevented by corresponding measures on the cable harness.

Electronic Controls for ZF-Powershift transmissions:

1.7.1 General:

Because of the different configurations of the electronic transmission controls at the various vehicles, the corresponding documentation must be taken from the operating Instructions of the Vehicle Manufacturer or from the Technical Data sheet of the concerned Parts List Versions. In these are also indicated the respective circuit diagram (see Sample Table-11) - and the connection diagram (upon request, these Informations can be asked for at the ZF Passau).

According to the type of vehicle, the wiring will be performed according to the wiring diagrams.

The corresponding electric circuit diagrams (proposals) will be realized by ZF. Upon request, the wiring can be also supplied by ZF. If the wiring will be realized by the Vehicle Manufacturer, it must be in accordance with the ZF-Requirements (see Installation Specification).

1.7.2 Description of the Basic functions: The Powershift transmission of the Ergopower-Series 4 WG-190/210 is equipped with the Electronic control unit EST-37, developped for it.

For Wheel loaders, Lift trucks and RoRo Trucks, the ZF has developped with the Controllers DW-3 and ERGO II a special Controller configuration.

The system is processing the desire of the driver according to the following criteria: • Gear determination depending on controller position, driving speed and load condition.

• Protection from operating error as far as necessary, is possible via electronic protection (programming).

• Protection from over-speeds (on the base of engine and turbine speed).

• Automatic reversing (driving speed-dependent, depending on vehicle type).

• Pressure cut-off possible (vehicle-specific, only after contact with ZF).

• Change-over possibility for Auto- / Manual mode.

• Downshifting functions possible.

Independent calibration of the Shifting elements (AEB)

The AEB has the task to compensate tolerances (plate clearance and pressure level) which are influencing the filling procedure of the clutches. For each clutch, the correct filling parameters are determined in one test cycle for: • •

Period of the quick-filling time Level of the filling compensating pressure

The filling parameters are stored, together with the AEB-Program and the driving program in the transmission electronics. Because the Electronics will be separately supplied, the AEBCycle must be started only after the installation of both components in the vehicle, thus ensuring the correct mating (Transmission and Electronics). any rate, the AEB-Cycle must be carried out at the Vehicle Manufacturer prior to the Atcommissioning of the vehicles.

It is imperative, to respect the following Test conditions: Shifting position Neutral Engine in idling speed Parking brake actuated Transmission in operating temperature

a replacement of the transmission, the electrohydraulic control or the TCU in the After vehicle, the AEB-Cycle must be as well carried out again.

The AEB-Cycle continues for about 3 to 4 minutes. The determined filling parameters are stored in the EEProm of the Electronics. In this way, the error message F6 shown on the Display will be cancelled also at non-performed AEB. the start of the AEB-Cycle, there are principally two possibilities: For 1. Start of the AEB by separate Tools which are connected on the diagnostic port of the wiring.

Following Tools for the AEB start will be offered by the ZF Service.: - Mobidig 2001 (see Point 5.2 – Diagnostic systems) - Testmann (see Point 5.3 – Diagnostic systems) - AEB Starter Order-No.: 0501 211 778 The Special Tool, developped by the ZF for it can be used only for the starting of the AEB ! (see Figure-No.: 1.7.3) Figure-No.: 1.7.3 B1

Down-Shift Button - 3: Function:

Every actuation is leading to a downshifting for one speed.

The Down-Shift Button (pushbutton) must be in all 3 possibilities provided by the Customer-side, if as Controller the DW-3 or ERGO II with integrated Down-Shift Button will not be used.

1.7.5 Pressure cut-off In order to provide, e.g. at Shovel loaders, the full engine power for the hydraulic system, the control can be enlarged for the function of a pressure cut-off in the 1st and 2nd speed. In this way, the pressure in the powershift clutches will be cut-off, and the torque transmission in the drive train will be eliminated by it. This function will be released at the actuation of a switch, arranged on the brake pedal. For a soft restart, the pressure will be build-up via a freely programmable characteristic line.

1.7.6 Inching device This function is especially suitable for Lift trucks. It allows to reduce the driving speed infinitely variable without modification of the engine speed in such a way that driving with a very low speed will be possible. In this way, the driver can move the vehicle very exactly to a determined position.

At the same time, an important part of the engine power for the output of the hydraulic system is at disposal by the high engine speed. The operation is realized via a separate inching pedal.

With increasing pedal travel, the driver can reduce the driving speed. The special Software is regulating the pressure in the driving direction clutch in such a way that the driving speed will be adjusted on the inching pedal according to the setting. A clutch overload will be prevented by an integrated protection.

1.7.7 Special functions According to the desires of the Vehicle Manufacturer, further additional functions can be programmed. Functions such as can be realized: * Selection of a Parking brake * Automatic Neutral shifting at vehicle standstill * Gear range limitation depending on determined Input signals * Blocking of the speed engagement beyond a determined Engine speed * Upshifting prevention in the overrunning range Further available Special function upon request after contact with the ZF.

II. INSTALLATION SPECIFICATION This Specification for the installation of hydrodynamic Powershift transmissions of the Ergopower-Series is the basis for the technically faultless installation of these transmissions in the vehicle. The Installation Specification is part of the Transmission Documentation and must be absolutely respected.

A faulty installation of the transmission into the vehicle, can * * *

affect the operating quality, cause malfunctions of the transmission, lead to transmission damages, resp. transmission failures.

Responsible for the correct installation of the transmission is the Vehicle Manufacturer.

ZF does not admit any guarantee or warranty claims for damages which has been caused by a faulty installation.

In order to assist the Customer in case of new, resp. initial applications, the ZF carries out by authorized personnel a transmission installation check. On this occasion, all transmissionspecific installation features are examined and the Vehicle Manufacturer, resp. the Equipment Manufacturer will be informed about the encountered defects.

At improperly installation, ZF reserves itself the right to acknowledge no guarantee for the installed ZF-Products.

For damages, caused by defects for which the Vehicle Manufacturer is responsible, and could not be discovered at the installation examination by ZF-Personnel, the Vehicle Manufacturer alone is liable.

OPERATION Driving preparation and Maintenance:

Prior to the commissioning of the transmission, take care that the prescribed oil grade will be filled in with the correct quantity. At the initial filling of the transmission has to be considered that the oil cooler, the pressure filter as well as the pipes must get filled with oil.

According to these cavities, the quantity of oil to be filled in, is greater than at the later oil fillings in the course of the usual Maintenance service.

Because the converter and also the heat exchanger, installed in the vehicle, as well as the pipes can empty at standstill into the transmission, the Oil level check must be carried out at engine idling speed and operating Temperature of the transmission (see Chapter Oil level check 4.2).

At the oil level check, the prescribed safety directions according to § 6 of the regulations for the prevention of accidents for power plants in Germany, and in all other countries, the respective national regulations have to be absolutely observed.

For example, the vehicle has to be secured against rolling by blocks, articulated vehicles additionally against unintended turning-in.

3.2

Driving and Shifting: Which control lamps in the INFOCENTER (dashboard) are illuminated for the functional control, can be different from Vehicle Manufacturer to Vehicle Manufacturer.

Control elements and displays can be from the ZF, however can be also customerspecific products; the precise specifications must therefore be taken from the Operating Instructions of the respective Vehicle Manufacturer.

- Neutral position: Neutral position will be selected via the Controller.

After the ignition is switched on, the electronics remains in the waiting state. By the position NEUTRAL of the Controller, resp. by pressing the pushbutton NEUTRAL, the EST-37 becomes ready for operation.

Now, a gear can be engaged.

- Starting: The starting of the engine has always to be carried out in the NEUTRAL POSITION of the Controller.

For safety reasons it is to recommend to brake the vehicle securely in position with the parking brake prior to start the engine.

After the starting of the engine and the preselection of the driving direction and the gear, the vehicle can be set in motion by acceleration.

27

ERGOPOWER

Geschäftsbereich Arbeitsmaschinen-Antriebe und Achssysteme

At the start off, the converter takes over the function of a master clutch.

On a level road it is possible to start off also in higher gears.

- Upshifting under load.

Upshifting under load will be then realized if the vehicle can continue to accelerate by it.

- Downshifting under load.

Downshifting under load will be then realized if more traction force is needed.

- Upshifting in overrunning condition.

In the overrunning mode, the upshifting will be suppressed by accelerator pedal idling position , if the speed of the vehicle on a downgrade should not be further increased.

- Downshifting in overrunning condition.

Downshifting in overrunning mode will be then carried out if the vehicle should be retaded.

- Reversing See important Note – Page 9.

If the vehicle will be stopped and is standing with running engine and engaged transmission, the engine cannot be stalled. On a level and horizontal roadway it is possible that the vehicle begins to crawl, because the engine is creating at idling speed a slight drag torque via the converter.

It is convenient to brake the vehicle at every stop securely in position with the parking brake.

At longer stops, the Controller has to be shifted to the NEUTRAL POSITION. At the start off, the parking brake has to be released. We know from experience that at a converter transmission it might not immediately be noted to have forgotten this quite normal operating step because a converter, due to its high ratio, can easily overcome the braking torque of the parking brake.

Temperature increases in the converter oil as well as overheated brakes will be the consequences to be find out later.

Neutral position of the selector switch at higher vehicle speeds (above stepping speed) is not admissible.

Either a suitable gear is to be shifted immediately, or the vehicle must be stopped at once.

3.3

Cold start:

At an oil temperature in the shifting circuit < -12° C, the transmission must be warmed-up for some minutes.

This must be carried out in Neutral with an increased engine speed (about 1500 min-1).

Until this oil temperature is reached, the Electronics remains in Neutral, and the symbol of the cold start phase will be indicated on the ZF-Display.

Indication on the Display : After the indication on the ZF-Display is extinguished, the full driving programm can be utilized out of „NEUTRAL“.

28

ERGOPOWER 3.4

Geschäftsbereich Arbeitsmaschinen-Antriebe und Achssysteme

Transmission control in the Driving mode Automatic: Precise Informations about the design of the Controllers as well as the speeds shifted in the single driving ranges, must be taken from the Operating Instructions belonging to the vehicle.

A manual intervention into the automatic shift sequence is only then practical if the roadway condition or the configuration of the ground is suitable.

3.5

Stopping and Parking:

Since due to the converter there is no rigid connection existing from the engine to the axle, it is recommended to secure the vehicle on upgrades, resp. downgrades against unintended rolling not only by applying the parking brake but additionally by a block on the wheel, if the driver has the intention to leave the vehicle.

3.6

Towing:

See Important Instructions – Page-10.

3.7

Oil temperature:

The oil temperature in the transmission sump is monitored by a temperature sensor in the electrohydraulic control unit.

The service temperature in the sump of 60° - 90° C must not be exceeded (indication appears on the Display in the cabine) !

At a trouble-free unit and an adequate driving mode, a higher temperature will not occour. If the temperature is rising above 90° C, the vehicle has to be stopped and controlled for external oil loss and the engine must run with a speed of 1200 – 1500 min-1 at NEUTRAL POSITION of the transmission.

Now, the temperature must drop quickly (in about 2 – 3 minutes) to normal values. If this is not the case, there is a trouble pending, which must be eliminated prior to continue working.

The monitoring of the oil temperature is additionally realized behind the converter with an indication on the ZF-Display or analog in the INFOCENTER. Operating temperature behind the converter at least 65° C and 100° C in continuous operation, a short-time increase up to max. 120° C is permitted.

The temperature is measured on the measuring point „63“ (see Schedule of measuring points – Table-8 !)

MAINTENANCE Oil grade: Permitted for the Powershift transmissions 4 WG-190/210 are oils according to ZFList of lubricants TE-ML 03.

list of lubricants is being continuously updated and can be obtained or viewed as The follows: - At all ZF-Plants - At all ZF-Service Stations - Internet http://www.zf.com Informationen/Tech. Informationen 4.2

Oil level check (measurements only with running engine):

At the oil level check, the prescribed safety directions according to § 6 of the rules for accident prevention for power plants in Germany, and in all other countries the respective national regulations have to be absolutely respected.

For example, the vehicle has to be secured against rolling with blocks, articulated vehicles additionally against unintended turning-in.

The oil level check must be carried out as follows: - Oil level check (weekly) - At horizontally standing vehicle - Transmission in Neutral position „N“ - In the cold start phase, the engine must be running about 2 – 3 minutes at idling speed, and the marking on the oil dipstick must then be lying above the cold start mark „COLD“ (see Figure-No. 4.2 B2) - At operating temperature of the transmission (about 80° - 90° C) With engine idling speed all measurements must be carried out with low engine idling speed.

- Loosen oil dipstick by counterclock rotation, remove and clean it - Insert oil dipstick slowly into the oil level tube until contact is obtained, and pull it out again.

- On the oil dipstick, the oil level must be lying in the zone „HOT“ (see Figure-No.: 4.2 B2) - Insert the oil dipstick again, and tighten it by clockwise rotation

If the oil level has dropped in operating temperature condition below the „HOT“ Zone, it is absolutely necessary to replenish oil according to the ZF-List of lubricants TE-ML-03.

An oil level above the „HOT“ marking, is leading to a too high oil temperature.

The oil dipstick and the oil filler tube can have different lengths and shapes, according to the Transmission version. Besides, the mounting on the transmission can be optionally realized on the converter side or on the rear side.(In this Illustration, the mounting of the oil dipstick is illustrated on the rear side).

- Fill in oil (about 21 liters) according to ZF-List of lubricants TE-ML 03.

(Sump capacity, external oil capacities e.g. in the heat exchanger, in the lines etc. are dependent on the vehicle).

The indicated value is a guide value.

-

It is imperative to pay attention to absolute cleanliness of oil and filter !

Binding is in any case the marking on the oil dipstick !

Start the engine – idling speed Transmission in Neutral position „N“ Top up oil up to the marking „COLD“ Brake the vehicle securely in position and warm up the transmission Shift all Controller positions through Check the oil level once more and top up oil once more if necessary On the oil dipstick, the oil level must be lying in the Zone „HOT“ (see Figure-No.: 4.2 B2) Insert the oil dipstick again and tighten it by clockwise rotation.

At the initial filling of the transmission has to be considered that the heat exchanger, the pressure filter as well as the pipes must get filled with oil.

According to these cavities, the oil capacity to be filled in is greater than at the later oil fillings in the course of the usual Maintenance service.

ZF recommends, to start the AEB at every oil change (see 1.7.3).

4.3.2 Filter replacement: At the replacement of the ZF-Filter in the main oil stream, pay attention that no dirt or oil sludge can penetrate into the circuit. Besides, the parking brake has to be covered, resp. protected from oil wetting.

At the mounting of the filter, any exertion of force has to be avoided.

The filters are installed separately from the transmission in the vehicle !

Treat the filter carefully at the installation, the transport and the storage !

Damaged filters must no more be installed !

The filter differential pressure valve (bypass valve) is equipped with a maintenanceswitch (opening switch) which is informing the driver about the contamination of the ZF-Fine filter.

At the lighting up of the symbol, the ZF-Fine filter must be replaced.

The mounting of the filter must be carried out as follows: - Cover the gasket with a small amount of oil.

- Screw the filter in until contact with the sealing surface is obtained and tighten it now by hand about 1/3 to 1/2 turn.
