6 WG-210
Information:
Due to the great variety of ZF units it is necessary to limit disassembly and reassembly manuals to
a current ZF production unit.
This documentation has been developed for specialized staff trained by ZF for repair work to be
done on ZF units.
Continuous technical upgrading of ZF units and extensions concerning design options may require
both deviating work steps and differing setting and testing data.

This disassembly and reassembly manual is based on the design level of a ZF production unit at
the time of issue of the manual.

ZF Friedrichshafen AG reserves the right to replace this disassembly and reassembly


manual by a successive edition at any time without advance notice. Upon request, ZF
Friedrichshafen AG will advise which edition is the latest one.

The list of lubricants is being continuously updated and can be obtained or viewed as follows:
- At all ZF plants
- At all ZF service organizations
- Internet http://www.zf.com/
----------------------------------------------------------------------------------------------------------------------------------
For information concerning description, installation instructions, operation and
maintenance, see respective Operating Instructions, ZF-Ordering-No. 5872 196 002.

ATTENTION:
Observe the vehicle manufacturer’s instructions and specifications for the installation and
commissioning of the unit!

PREFACE

This documentation has been developed for skilled staff trained by the ZF )ULHGULFKVKDIHQ$* for the
repairandmaintenance works on ZF-units.

Documented is a ZF-serial product representing the design state at the time of the edition.

However, due to further technical developments of the product, the repair of the unit at your disposal could
require different steps as well as different adjustments and testing specifications.

Therefore, we recommend to commit your ZF-product to foremen and technicians whose practical and
theoretical training is permanently updated in our after-sales service school.

The service stations established world-wide by the Zahnradfabrik Friedrichshafen are offering to you:

1. Continuously trained staff

2. Prescribed facilities, e.g. special tools

3. Genuine ZF-spare parts meeting the latest state of development

Here, all operations are carried out for you with utmost care and reliability.

Repairs carried out by ZF-service stations are covered by a respective warranty within the scope of
the applicable contractual conditions.

Damage caused by improper or unskilled work carried out by others than ZF-staff as well as resulting
consequential costs, if any, are excluded from this contractual liability.
This also applies, if the use of genuine ZF-spare parts is renounced.

GENERAL

The Service Manual covers all works required for dismantling and the pertaining installation.

When repairing the transmission, ensure utmost cleanliness and that the works are carried out in an expert-
like manner.
The transmission should only be disassembled for renewing damaged parts. Covers and housing parts
installed with seals must be loosened by slight blows with a plastic mallet after screws and nuts have been
removed. For removing parts being in tight contact with the shaft such as antifriction bearings, bearing
races, and similar, use suitable pulling devices.

Dismantling and mounting works must be carried out at a clean working place. Use the special tools
developed for this purpose. Prior to the re-installation of the parts, clean the contact surfaces of housings
and covers from the residues of old seals. Remove burrs, if any, or similar irregularities with an oil stone.
Clean housings and locking covers with a suitable detergent, in particular corners and angles. Damaged
parts or parts heavily worn down must be renewed. Here, the expert must assess, whether parts such as
antifriction bearings, thrust washers etc. subjected to normal wear during operation, can be installed again.
Parts such as sealing rings, lock plates, split pins etc. must generally be renewed. Radial sealing rings with
worn down or torn sealing lip must also be renewed. Particularly ensure that no chips or other foreign
bodies remain in the housing. Lube oil bores and grooves must be checked for unhindered passage.
All bearings must be treated with operating oil prior to installing them:

REFE- For heating up parts such as bearings, housings etc., only a heating furnace or an electric
RENCE: drier is permitted to be used!

CAUTION
When assembling the transmission, absolutely observe the indicated torque limits and adjustment data.
Screws and nuts must be tightened according to the enclosed standard table, unless otherwise specified.
In view of the risk of functional failures in the control unit, the use of liquid sealing agents is not permitted.
By no means, Molykote is permitted to be used.
Lined plates must not be washed. They must be cleaned with a leather cloth.

DANGER
When using detergents, observe the instructions given by the manufacturer regarding
handling of the respective detergent.

Structure of the Repair Manual

The structure of this Repair Manual reflects the sequence of the working steps for completely disassembling
the dismantled transmission. Dismantling and installing as well as the disassembly and assembly of a main
group are always summarized in one chapter.
Special tools required for performing the respective repair works are listed under „Special tools“.

Important information on industrial safety

Generally, the persons repairing ZF-sets are responsible on their own for the industrial safety.

The observation of all valid safety regulations and legal impositions is the pre-condition for avoiding
damage to persons and to the product during maintenance and repair works.
Persons performing repair works must familiarize themselves with these regulations.

The proper repair of these ZF-products requires the employment of suitably trained and skilled staff.
The repairer is obliged to perform the training.

The following safety references are used in the present Repair Manual:

 Serves as reference to special working procedures, methods,


information, the use of auxiliaries etc..

CAUTION Is used, if a deviating and improper working procedure can


damage the product.

Is used, if lacking care can lead to personal injury or danger to


DANGER life.

___________________________________________________

REFE- Prior to starting the checks and repair works, thoroughly study the present instructions.
RENCE

CAUTION: Illustrations, drawings and parts do not always represent the original; the working procedure
is shown.
The illustrations, drawings, and parts are not drawn to scale; conclusions regarding size and
weight must not be drawn (not even within one representation).
The works must be performed according to the description..

REFE- After the repair works and the checks, the expert staff must convince itself that the product is
RENCE: properly functioning again. .
