Mount the spacers and adjustment rings in the same number,
thickness and position found during disassembly, in the
following order: spacer (1), adjustment ring (2), adjustment
ring (3) and spacer (4).
Position the sliding sleeve in the rear axle housing for
differential locking (if present). Mount the external rings (1)
for the gear housing support bearings and then position the
previously mounted gear housing in the rear axle housing.

Position a new seal ring over the gear housing inspection
attachment surface.
Mount the cover (3), insert the fixing screws (2) complete
with tab washers and spring washers.
Tighten the screws (2) with the torque wrench (1) to the
required tightening torque.
Mount the differential locking device (if present) and adjust
it as described under the relevant heading.
Mount the drive shafts as described under heading: “525030
Overhauling the Hubs”.
Screw on the oil drainage plug and tighten it to the required
torque.
Add lubricating oil in the required quantity and grade through
the hole.
Screw on the oil filler plug and tighten it to the required
torque.
Take the assembly off the stand.
The assembly should be put back on its mounting
to prevent the dust guards and/or brake discs from
getting damaged.
Do not tighten the screws to a torque greater than
the value indicated since this would impair the
sealing effect of the gasket placed between the
coupling plane and the gear housing inspection
cover.
