Checking the clearance of the drive and intermediate shafts
1a - Drive shaft ball bearing; 1b, 1c, 127 - Retaining rings; 2 - Drive shaft; 40 - Intermediate shaft; 92 - Front gearbox cover; 128 - Intermediate shaft ball bearing; S1 - Drive shaft clearance; S2 - Intermediate shaft clearance
1. Measure the clearance between the ball bearing of the input shaft and the front cover of the gearbox. The nominal value of the clearances is 0.1 mm.
2. Measure the distance "a" between the bearing outer ring and the gearbox housing contact surface using a caliper.
3. Measure the distance "b" between the sealing surface of the gearbox cover and the bearing groove using a caliper.

4. The thickness of the gaskets is calculated as follows: Distance "b" (6.1 mm) - Distance "a" (5.2 mm) = Difference (0.9 mm) - Gap (0.1 mm) = Gasket thickness (0.8 mm). Gaskets are available in thicknesses of 0.2, 0.3 and 0.5 mm.
5. Insert the gaskets into the front gearbox cover and secure them with grease.
6. Check the clearance between the intermediate shaft ball bearing and the front gearbox cover.
7. Install the intermediate shaft with the ball bearing into the gearbox housing using a plastic hammer.
8. Measure the distance "c" between the outer ring of the bearing and the contact surface of the gearbox housing using a caliper.
9. Measure the distance "d" between the sealing surface of the front gearbox cover and the groove using a caliper.
10. Determine the thickness of the shims: Distance "d" (5.8 mm) - Distance "c" (5.1 mm) = Difference (0.7 mm) - Gap (0.1 mm) = Thickness of the shim (0.6 mm). The shims are available in thicknesses of 0.2, 0.3 and 0.5 mm.
11. Insert the gaskets into the front gearbox cover and secure them with grease.
Installation is carried out in the reverse order of removal.
