Adjust the input shaft when one of the following elements has been replaced: l  Gearbox l  clutch housing l  Input shaft: l  4th gear wheel l  Input shaft tapered roller bearing See adjustment overview → Chapter.

–  Fit the input shaft outer roller bearing track to the gearbox housing, without the shim, with adapter -U-40200/10- and adapter -U-40200/13-. –  Assemble the gearbox casing on the clutch housing, and tighten the securing bolts to corresponding torque → Item.

–  Install support -T20020- with a comparator on the clutch housing. Locate the end of the dial gauge on the input shaft. –  Turn the input shaft to settle the roller bearings. –  Adjust the dial gauge „0“ with a pre-tension of 1 mm.   Note The adjustment to „0“of the dial gauge must be repeated every time the measurement is carried out. Otherwise the dial gauge will not return to the initial position. –  From the bottom of the gearbox, press the input shaft in the direction of the comparator. –  Note the reading on the comparator (e.g. 1.21 mm).   Note Dial gauge does not return to original setting by itself.

Note Allocate shims according to → Electronic parts catalogue „ETKA“. –  Once the necessary shim has been determined, remove the dial gauge. –  Remove the bolts that secure both casings and remove the gearbox casing. –  Remove the input shaft from the clutch housing.

–  Remove the input shaft outer roller bearing track from the gearbox housing with adapter -U-40200/10- and adapter -U-40200/13-. –  Install the outer roller bearing track in the gearbox housing with the selected shim (in this case, 1.175 mm). –  Place the input shaft in its housing in the clutch housing. –  Assemble the gearbox casing on the clutch housing and tighten the securing bolts to corresponding torque. –  Carry out a measurement → Fig.

Measurement –  Install support -T20020- with a comparator on the clutch housing. Locate the end of the dial gauge on the input shaft. –  Turn the input shaft to settle the roller bearings. –  Adjust the dial gauge „0“ with a pre-tension of 1 mm. –  From the bottom of the gearbox, press the input shaft in the direction of the comparator. –  The bearing clearance must be at least 0.01 min. and max. 0.10 mm.   Note If it is impossible to determine any bearing clearance, but the input shaft has a perceptible clearance and can be gently turned, the adjustment is correct.
