Refit the differential in the housing, with the bearing
lightly oiled.
Fit the sunwheel side bearing, the pre-tensioning
setting washer and the nut.
As for disassembly, immobilise the unit/crownwheel
assembly using tool B. Vi. 1057.
Pre-tighten to a torque of 1 to 2 daNm.
Remove tool B. Vi. 1057 and rotate the differential to fit
the bearings.
Refit tool B. Vi. 1057 and tighten the nut to a torque of
13 daNm.
Remove tool B. Vi. 1057 and rotate the differential and
check the pre-tension.
MANUAL GEARBOX
Repairing the gearbox
The differential must rotate under a load of between:
– 0.5 and 2 daNm for reused bearings,
– 1.6 and 3.2 daNm for new bearings.
If the setting is not correct:
Determine the thickness of the timing washer bearing
in mind that:
19811
The pre-tension increases by approximately 0.7 to
0.8 daNm when the timing washer thickness is
reduced by 0.05 mm and vice-versa.
