18. Unscrew bolts (27), at which time the crown wheel is
released and the differential housing is split.
19. Remove cover (12) and change o---ring (24).
20. Remove piston (22) and change o---rings (21) and (23).
21. Remove the disc pack (9, 10, 11) (note the fitting order.
Steel discs have teeth on the outer circumference) and
check the condition of the discs. If the disc wear can be
found, change all discs at the same time. Thickness of the
discs, see page 670/2.
22. Remove and check the condition of the differential pin-
ions. Before removing, remove tension pins (5).
Note! In connection with damages, change all parts under
pos. no. 25.
23. Check/change seals (23) and o---ring (27).

25. Assembling is done in a reverse order.
26. Lock the differential pinions with pins (5). Fit the disc
pack and the differential side gears (disc pack contains 1
thrust plate, 8 steel discs and friction discs. Steel discs
have teeth on the outer circumference).
27. Refit piston (22) and its o---rings (23) and (21), cover
(12) and o---ring (24).
Note! The differential gears have thrust washers with differ-
ent thickness, see technical data. In addition, the differential
gears have a certain tooth backlash, see technical data. If
the thrust washers must be changed, the tooth backlash
must be checked with a dial gauge.
