The differential gear must be re-set when the following components are replaced:
t  Gearbox housing
t  Clutch housing
t  Differential gear housing
or the
t  Tapered-roller bearings of the differential gear.
   
On gearboxes made out of aluminium as of production date 12.06 the adjusting washer S1 for outer ring/tapered-roller bearing is not fitted
Bearing pedestal for outer ring/tapered-roller bearing is adapted.
–  Measure the depth of the bearing pedestal for the outer ring/tapered-roller bearing in the clutch housing.

–  Press the outer ring/tapered-roller bearing (on the riveted pinion side of the differential housing) with adjusting washer S1 (always 1mm thick) into the clutch housing made out of magnesium or without adjusting washer into the clutch housing made out of aluminium.
  Note
The inner and outer rings of the tapered-roller bearing are paired - do not interchange.

–  Press the outer ring/tapered-roller bearing (opposite side) without adjusting washer into the clutch housing.
–  Insert the differential gear housing together with the installed inner rings/tapered-roller bearings into the gearbox housing.
–  Position the clutch housing and tighten 5 screws to the given tightening torque → Chapter.

–  Set the dial gauge to 0 with 1 mm preload on „0“.
A - Dial gauge extension 30 mm
–  Set the dial gauge to „0“ with 1 mm bias.
–  Move the differential gear up and down in the direction of the axle, read off and write down the clearance on the dial gauge (example: 1.50 mm).
  Note
Do not turn the differential gear while measuring as otherwise the bearings will settle and the measuring result will be inaccurate.
