(91 & 95) then check that cage half (96) and clutch
plates will slide in differential housing body (48) by
raising and lowering wheel (97).
11. If originally fitted, place shims on end face of
differential housing body (48). Install second thrust
washer (53) onto wheel (97) then carefully offer end
flange (93) to the assembly, lining up matching marks
(See Fig. 10).
12. Secure assembly with nuts (92) then tighten to a
torque of 61 - 66 Nm (45 - 49 lbf ft).
13. To check assembly of differential unit, insert a half
shaft to engage with each wheel (97). Hold one half
shaft to lock wheel; the other must turn freely.
14. Press bearing cone (52A) onto each end flange (49

Initial Preparation Before Installing
Assembled Differential Unit
Note: Secure the crownwheel and gear casing
assembly in a suitable diff build stool.
Check fit of adjusting nuts (51) as follows:
1. Clean and deburr gear casing (39) legs and
straps (89).
2. Install bearing cups (52) into half bores of gear
casing (39) legs.
3. Check studs (100), and replace as necessary.
Tighten to a torque of 129 - 142 Nm (95 - 105 lbf ft).
4. Carefully install two straps (89) and adjusting nuts
(51) to locate on bearing cups (52). Check alignment of
matching marks on gear casing (39) legs and straps
(89) to ensure that straps are not transposed. Bearing
cups (52) should seat snugly in bores and adjusting
nuts (51) should be free to turn with hand pressure
