Differential shim: determining

Insert the outer ring of the conical roller bearing into the clutch housing. l  Insert the conical roller bearing outer ring with a 0.65 mm shim into the clutch housing –  Press the gearbox casing directly onto the base of the bearing using the kit (case) -U-40200A- .   Note The inner and outer roller bearing rings are paired. Do not mix them up.

Insert the outer ring of the conical roller bearing into the gearbox housing. –  Support the gearbox casing on the base -U-40450/1- with the adapter -U-40450/11-, socket -U-40450/4- and as a base for connecting the inner ring, the installation tool -U-10103-, adapter -U-40200/10- and the adapter -U-40200/5-. –  Insert the differential on the clutch casing. –  Fit onto the gearbox casing and tighten the 5 bolts. Tightening torque → Item. –  Press the differential towards the gearbox casing rotating it 8 times. –  Fit the support -T20020- and the measurement tool together onto the gearbox casing.

–  Fit the gauge and set to “0” with a pretension of 1 mm. A -  30 mm extension for dial gauge –  Move the differential upwards and downwards, read the play indicated by the gauge and note it (in the example: 0.70 mm). Determining thickness of shim: The specified pre-tension for the bearing is obtained by adding a constant pressure value (0.25 mm) to the measured value.

Example:
Average value	0.70 mm
+ Pressure (constant value)	0.25 mm
Shim thickness =	0.95 mm

–  Determine the shim or the shims using the table. Depending on version → Parts catalogue. –  Remove the gearbox casing.

Remove the outer ring of the conical roller bearing from the gearbox casing –  Use the extractor kit -T20140- with adaptor -T20140/30-. –  Fit the shim or shims according to the table, (the shim of the calculated measurement is fitted, or the closest larger one). –  Re-insert the outer ring and tighten the gearbox casing with the correct torque.

Insert the outer ring of the roller bearing into the gearbox casing –  Support the gearbox casing on the base -U-40450/1- with the adapter -U-40450/11-, socket -U-40450/4- and as a base for connecting the inner ring, the installation tool -U-10103-, adapter -U-40200/10- and the adapter -U-40200/5-.
