Installation
With the aid of a device (B.Vi.1059) and a press, install the bearing cages against the stop in the crankcase shoulders.
Insert the differential housing into the crankcase, lightly oiling the bearings.
Install the planetary side bearing, preload adjustment ring and nut.
As when removing, fix the assembly «differential housing-driven gear» using a device (B.Vi.1057).
Pre-tighten to 10-20 Nm.
Remove fixture (V.Vi.1057) and rotate the differential case. to keep the bearings in place.
Install fixture (V.Vi.1057) and tighten the solder with a torque of 130 Nm.
Remove fixture (V.Vi.1057) and rotate the differential case.
Check pretension.
The differential must rotate when the following loads are applied:
- 5-20 Nm for reusable bearings:
- 16-32 Nm for new bearings.
If the adjustment does not correspond to these values, determine the thickness of the adjusting ring. At the same time, taking into account that the pretension increases by about 7-8 Nm with a decrease in the thickness of the adjusting ring by 0.05 mm, and vice versa.
