It is necessary to readjust the differential when the following components are renewed:
- Gearbox housing
- Clutch housing or
- Differential cage
or the
- Differential tapered roller bearing
- Insert the outer ring of the roller bearing (crown side) into the gearbox casing
Note Inner and outer tapered roller bearing races are paired. Do not interchange!
- Press tapered roller bearing outer race (opposite gear wheel) with no shim into gearbox housing.
- Insert differential in gearbox housing.
- Fit clutch housing and tighten 5 bolts to specified torque.
- Fit the gauge and set to "0" with a pretension of 1 mm.
A - 30 mm gauge extension
- Set dial gauge to "0" with 1 mm preload for bearing.
- Move the differential up and down while reading the measurement on the gauge and noting the results (for example: 1.50 mm raised).
Determining thickness of shim.
The specified bearing preload is obtained by adding a constant value for preload (0.35 mm) to the reading obtained.
As an example:
- Remove clutch housing and press out tapered roller bearing outer race -A-.
B - Internal puller - VAS 251 615- , or e.g. -Kukko 21/7-
- Allocate the shim(s) using - Electronic parts catalogue (ETKA) .
The existence of different thickness shims will enable the selection of the correct thickness required.
If the size of the shim required is larger than those listed in - Electronic spare parts catalogue (ETKA) install two shims amounting to the correct value.
- Fit the shim of right thickness (for this example 1.85 mm) and reinsert the outer ring of the conical bearing into the clutch housing.
- Fit clutch housing and tighten bolts.
Specified torques
- Gearbox housing to clutch housing
