REPAIR MANUAL for the ZF – TRACTOR TRANSMISSION T-7336 PS I M P O R T A N T N O T E: The great variety of ZF units compels a restriction of the Disassembly and Assembly Manuals to a current ZF production unit. Technical development of the ZF units as well as extensions concerning the design possibilities may require differing steps, which can be carried out by qualified Specialists without greater difficulties with the help of the Perspective Illustrations in the corresponding Spare Parts Lists. The described Disassembly and Assembly Manual is based on the design level of a ZF production unit at the time of preparation of the Repair Manual. The ZF Passau GmbH reserve the right to replace the present Disassembly and Assembly Manual by a successional edition without advance notice. Upon request, the ZF Passau GmbH will advise what edition is the latest one. ATTENTION: For the Installation as well as for the commissioning of the unit, the Instructions and Specifications of Vehicle Manufacturer have to be observed! For information about the Operation, Maintenance and Description, see the corresponding ZF Operating Instructions.

Repair Manual Off-Road Transmissions and Axle Systems Division 5871 970 002 0/2 GENERAL The Service Manual covers all work required for dismantling and the pertaining installation. When repairing the axle, ensure utmost cleanliness and that the work is carried out in an expert-like manner. The axle 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 work 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- RENCE: For heating up parts such as bearings, housings etc., only a heating furnace or an electric drier is permitted to be used! Parts fitted in heated state have to be installed subsequently after cooling down to ensure a perfect contact! 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. Lined plates with organic friction linings (e.g. paper linings) must not be washed (negative effect on lining adhesion). They are only allowed to be dry-cleaned (leather cloth). For the installation of circlips and retaining rings it must be observed that slots are located exactly. DANGER When using detergents, observe the instructions given by the manufacturer regarding handling of the respective detergent.
