Set l  The gearbox is secured on the assembly stand l  The sealing surfaces of both the gearbox and the clutch housings should be free of sealant l  To carry out the measurement, only fit the shaft to be measured

Insert the outer ring/tapered roller bearing –  Insert the roller bearing outer ring with a 1.70 mm shim into the gearbox housing; to do this support the housing by fitting the kit -U-40200/14- underneath the bearing allotment. –  Now insert the complete 5th / 6th / reverse gear output shaft in the clutch housing.

–  Attach the gearbox case and tighten the screws -A- Tightening torque → Item Tighten the securing bolts -B- Tightening torque → Item

–  Set up measuring tools and secure to clutch housing using bolt -arrow-. –  Fit the support -T20020- and measurement tools securing them to the clutch housing with the bolt -arrow-. –  Put the dial gauge (3 mm range) to „0“ with a pretension of 1 mm. –  Loosen, diagonally, the bolts securing the clutch housing to the gearbox until the gearbox housing or the secondary shaft may be lifted. –  Read the value indicated by the dial gauge and note it (in the example: 0.25 mm).   Note When loosening the bolts securing the clutch housing to the gearbox, no value is indicated on the dial gauge, the shim of 1.95 mm or that of 2.20 mm must be fitted to make the measurement. Determining thickness of shims The specified bearing preload is attained by subtracting the measured value (0.25 mm) from the inserted shim (1.70 mm) and adding a constant value for preload (0.20 mm).

Example:
shim fitted	1.70 mm
- Measured value	0.25 mm
+ Preload (constant)	0.20 mm
Thickness of shim	1.65 mm

–  Determine the thickness of the shim by using the table. Depending on version → Current Spare parts catalogue .

–  Remove the gearbox casing and extract the outer ring of the roller bearing from it. –  Extract the conical roller bearing outer ring and the bearing sockets using the extractor kit -T20140-. –  Remove the shim fitted (1.70 mm) from the gearbox housing.

–  Insert the roller bearing outer ring with the shim of the determined thickness (in this case 1.65 mm) into the gearbox housing; to do this support the housing directly underneath the bearing allotment using the kit (case) -U-40200A-.
