Assembly
-
Check all parts for wear or damage, and replace if necessary.
a) Differential Housing - Check guide grooves for outer splined discs and pressure rings for wear.
b) Pressure Rings - The guide tabs and bearing surfaces must not show excessive wear or scoring. They must also move easily in differential
housing.
c) Differential Gears - The bearing surfaces for the thrust washers must not be worn and the inner splined discs must move easily on the
serration of the differential gears.
d) Discs - Check inner and outer splined discs for wear. The guide tabs of the outer splined tabs of the outer splined discs and the inner
splined disc serration should not be worn.
-
Before installation, lubricate all sliding surfaces of the discs, the pressure rings and the differential shafts with hypoid gear lube SAE 90.
-
Insert thrust washers, so that the retaining tabs engage in the bore of the housing or housing cover. It is recommended to coat the washers with a
little grease to provide a better bold.
