Preface This manual is intended for skilled personnel trained by ZF Friedrichshafen AG to carry out maintenance and repair work on ZF products.

This manual deals with a ZF product in accordance with the state of development on the date of issue. However, due to continuing development of the product, repair work might require work practices and test or adjustment data which are not contained in this manual. We therefore recommend that work done on your ZF product is carried out only by skilled mechanics and fitters who have had their practical and theoretical knowledge updated on a regular basis at our After-Sales Service training courses.

Service points equipped by ZF Friedrichshafen AG all over the world offer you: 1. Well-trained personnel, 2. Specified equipment, e.g.: Special tools 3. Genuine ZF spares, according to our latest specifications

All work performed at these service locations is carried out conscientiously and with care. Warranty: Repair work carried out at ZF Service Points is subject to the contractual conditions prevailing in the individual case. ZF Friedrichshafen AG Nutzfahrzeug- und Sonder-Antriebstechnik Commercial Vehicle and Special Driveline Technology Service Werk 2 (Plant 2) Phone: +49 (0)7541 77-0 Fax: +49 (0)7541 77-908000 Internet: www.zf.com

2003-08

Damage resulting from work performed by non-ZF personnel in an improper and unprofessional manner, together with follow-on costs caused by such work, is excluded from the contractual warranty agreement. This also applies where genuine ZF spare parts have not been used.

Safety Instructions Safety Instructions

General Information

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.

CAUTION Pictures, drawings, and components do not always represent the original 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.

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.

After completion of repair work and testing, skilled staff must check whether the product is functioning correctly.

The following safety instructions appear in this manual:

!

THREATS TO THE ENVIRONMENT ! Lubricants, consumables, and cleaning agents must not be allowed to enter the soil, ground water, or sewage system. • 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 filters, lubricants, and cleaning agents in accordance with environmental protection guidelines. • When working with lubricants and cleaning agents always refer to the manufacturer’s instructions.

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.

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

Instructions for Repairs Gaskets, Locking plates

ZF Service Information must be observed. This information is available at all ZF Service Centers or via the ZF-ServiceLine.

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

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 by experts only and under clean conditions. Use specified tools to dismantle and assemble transmissions.

Shaft Seals Always change shaft seals with rough, ripped or hardened sealing lips. Seal contact surfaces must be totally clean and in perfect condition.

After removing the transmission from the vehicle, clean it thoroughly with a suitable cleaning agent before opening. Pay particular attention to the projections and recesses of housings and covers when cleaning.

Reworking

Parts joined with Loctite are easier to separate if warmed with a fan heater.

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 scroll.

Cleaning parts

If rework is needed on spacer discs, shims etc. because of clearance adjustment, ensure that the reworked areas contain no face runout and have the same surface quality.

Remove remains of old gaskets on all sealing surfaces. Carefully remove burrs or similar patches of roughness using an oilstone. Lube bores and grooves must be free of anticorrosion agents and foreign matter; check for perfect passage.

Transmission Assembly Find a clean work area to assemble the transmission. Gaskets are installed without sealing compound or grease. When measuring silicon-coated gaskets, do not include the silicon layer. During assembly, comply with all adjustment data and tightening torques in the Repair Manual.

Carefully cover opened transmissions to prevent foreign matter from entering.

Reusing parts Parts such as roller bearings, 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.

Instructions for Repairs d) Dual shaft seals have two sealing lips. The dust-proof sealing lip (X) must face outwards.

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

X

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.

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.

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, comply with all adjustment data, checking data, and tightening torques.

Shaft Seals a) Apply a light coat of sealing agent* on circumference of shaft seals with “steel jacket”.

Transmission oil b) Never apply sealing agent to shaft seals with “rubber jacket”, but apply a thin coat of Vaseline 8420 to the circumference or wet with a lubricant, e.g. a water-soluble, concentrated washing-up liquid (e.g. Pril, Coin, Palmolive).

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

c) Shaft seals with steel and rubber jackets should be treated on the circumference of the rubber jacket as described above in section b).
