1) GENERAL WORKING INSTRUCTIONS
(1) This manual has been developed for the skilled serviceman, trained by the ZF-Passau.
(2) During all operations, pay attention to cleanliness and skilled working.
Therefore, axle removed from the machine, must be cleaned prior to open them.
(3) We assume that the special tools, specified by ZF, will be used.
The special tools are available from ZF-Passau.
(4) After the disassembly, all components must be cleansed, especially corners, cavities and
recesses of housing and covers.
(5) The old sealing compound must be carefully removed.
(6) Check lubricating holes, grooves and pipes for free passage. They must be free of residues,
foreign material or protective compounds.
(7) The latter refers especially to new parts.
(8) Parts which have been inevitably damaged in a disassembly operation, must be generally
replaced by new ones, e.g. rotary seal rings, O-rings, U-section rings, cap boots, protective caps
etc..
(9) Components such as roller bearings, thrust washers, synchronizing parts etc. which are subject
to normal wear in automotive operation, must be checked by the skilled Serviceman.
He will decide if the parts can be reused.
(10) For the heating of bearings etc., hot plates, rod heaters or heating furnaces must be used.
(11) Never heat parts directly with the flame. An auxiliary solution would be to immerse the bearing in
a vessel filled with oil, which is then heated with the flame.
In this way, damage to the bearings could be avoided.
(12) Ball bearings, covers, flanges and parts like that must be heated to about 90 to 100˚C.
(13) Hot-mounted parts must be reset after cooling in order to assure a proper contact.
(14) Before pressing shafts, bearings etc. in position, both parts must be lubricated.
(15) During to reassembly, all specified adjustment values, testing specifications and tightening torque
must be respected.
(16) After the repair, units are filled up with oil.
(17) After the oil filling, the oil level plugs and oil drain plugs must be tightened to the specified
tightening torque.

8-217
2) IMPORTANT INSTRUCTIONS CONCERNING THE LABOUR SAFETY
(1) In principle, repairers are themselves responsible for the labour safety.
(2) The observance of all valid safety regulations and legal rules is a precondition to prevent damage
to individuals and products during the maintenance and repair operations.
(3) Before starting the work, the repairers have to make themselves familiar with these regulations.
(4) The proper repair of these products requires especially trained personnel.
(5) The repairer himself is obliged to provide for the training.
3) LUBRICANT SPECIFICATIONS
(1) Gear oils with limited - slip additives.
(2) API GL-5
(3) MIL-L-2105D (SAE 85W-90, 85W-140 with LS-Additive)

8-218
4) BRAKE LINING WEARING TEST
(1) The measurement of wear on the multi-
disc brake only gives limited information
on the total state of the plate pack without 1
disassembling the output.
Make measurement of lining wear at least 2
once per year, in particular, however, in
case of a different braking behaviour, like :
- Braking noises
- Reduced braking power
- Different deceleration 17W7A8AX03

- Different brake oil level

- Different braking pressure
ö To avoid injury when opening the oil drain/
oil filler plug (1), due to a possible
pressure build-up in the planetary carrier
bring drain hole to topmost position (12
o'clock) and carefully unscrew oil drain
and filler plug (1).

(2) Then turn output until oil filler / oil drain

hole (2) is on 9 o'clock position. 3
