Special tools and workshop equipment required

t	Gearbox repair set -U-40200-

t	Universal dial gauge bracket -T20020-

t	Gearbox-differential support column -AR-2203A-

t	Torque spanner -SAT 8010-

Adjust the input shaft when one of the following elements have been replaced: t  Gearbox casing t  Clutch housing t  Input shaft t  4th gear t  Input shaft roller bearings Refer to Adjustment chart → Chapter

–  Fit the input shaft outer roller bearing track to the gearbox housing, without the shim, with tool -U-40200/10- and tool -40200/13-. –  Locate the input shaft in its housing in the clutch casing. –  Fit the gearbox casing onto the clutch housing and tighten the securing bolts to 25 Nm + 90°.

–  Fit tool -T20020- on the clutch casing with a dial gauge. Locate the end of the dial gauge on the input shaft. –  Turn the input shaft to settle the roller bearings. –  Adjust the dial gauge to “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 lower end of the gearbox, press the input shaft in the direction of the dial gauge. –  Take note of the measurement obtained (e.g. 1.21 mm).   Note! The dial gauge does not return to its initial position. –  Determine the thickness of the shim with the table → Anchor. Shim table

–  Once the necessary shim has been determined, remove the dial gauge. –  Remove the bolts that secure both casings and separate the gearbox casing. –  Remove input shaft from clutch housing.

–  Remove the input shaft outer roller bearing track from the clutch housing, with tool -U-40200/10- and tool -U-40200/13-. –  Fit the outer track of the roller bearing in the gearbox housing with the correct shim (in this case 1.175 mm). –  Locate the input shaft in its housing in the clutch casing. –  Fit the gearbox casing onto the clutch housing and tighten the securing bolts to 25 Nm + 90°. –  Carry out a measurement → Anchor. Measurement

–  Fit tool -T20020- on the clutch casing with a dial gauge. Locate the end of the dial gauge on the input shaft. –  Turn the input shaft to settle the roller bearings. –  Adjust the dial gauge to “0” with a pretension of 1 mm. –  From the lower end of the gearbox, press the input shaft in the direction of the dial gauge. –  The bearing play should be min. 0.01 ... max. 0.10 mm.   Note! If no play can be measured but the input shaft is free and can turn easily, the adjustment is correct.
