4

Unscrew ring gear serrated bolts (3), hammer loose ring gear (1) from differential housing cover (2) and remove.

 Assembly:

Heat up ring gear to approx. 90 ° C and place on the support.

Insert differential in the ring gear, replace serrated bolts and screw on lightly.

5

Unscrew differential housing serrated bolts (4), detach thrust piece from support and remove differential housing cover (2).

 Assembling:

The position of the differential housing cover relative to the differential housing is marked by numbers marked which have to be opposite one another during assembly.

When installing insert the new serrated bolt and screw in lightly.

- Then remove the differential housing from the support.

6

Remove pressure plate (6), upper differential side gear (7), differential spider (8) with differential pinions (10), thrust races (9), bearing needles (11), spacer rings (12) and spherical washers (13) as well as lower differential side gear (7) and pressure plate (6) in sequence from the differential housing (14)

 In the process leave the differential housing in the support.

 Assembling:

Before assembly, apply thin coating of oil to all slide surfaces.

To optimize operational reliability of differential, it is advisable to fit repair kit if repairs become necessary.

7

In each case remove spherical washer (13), spacer ring (12), differential pinion (10), bearing needles (11) and thrust ring (9) in sequence from the differential spider (8)

 Clamp differential spider in the vise, use aluminum protective jaws in the process.

 Assembling:

Grease needle bearings lightly with MB-multipurpose grease.
