Checking the clearance of the drive and intermediate shafts
1a - Ball bearing of the drive shaft; 1b, 1c, 127 - Retaining rings; 2 - Drive shaft; 40 - Intermediate shaft; 92 - Front cover of the gearbox; 128 - Ball bearing of the intermediate shaft; S1 - Gap of the drive shaft; S2 - Intermediate shaft clearance
1. Measure the clearance between the input shaft ball bearing and the transmission front cover. The nominal value of the gaps is 0.1 mm.
2. Measure the distance «a» between the outer race of the bearing and the contact surface of the gearbox housing with a vernier caliper.
3. Measure the distance «b» between the sealing surface of the gearbox cover and the bearing groove with a vernier caliper.
4. Calculate the thickness of the gaskets as follows: Distance «b» (6.1mm) - Distance «a» (5.2mm) = Difference (0.9mm) - Clearance (0.1mm) = Gasket thickness (0.8mm). Gaskets are available in thicknesses of 0.2, 0.3 and 0.5 mm.
5. Insert gaskets into transmission front cover and secure with grease.
6. Check up a backlash between the ball bearing of an intermediate shaft and a forward cover of a transmission.
7. Install the intermediate shaft with ball bearing into the gearbox housing with a plastic mallet.
8. Measure the distance «With» between the outer race of the bearing and the contact surface of the gearbox housing with a vernier caliper.
9. Measure the distance «d» between the sealing surface of the gearbox front cover and the groove with a caliper.
10. Determine the thickness of the shims: Distance «d» (5.8mm) - Distance «With» (5.1mm) = Difference (0.7mm) - Clearance (0.1mm) = Gasket thickness (0.6mm). Gaskets are available in thicknesses of 0.2, 0.3 and 0.5 mm.
11. Insert the gaskets into the transmission front cover and secure with grease.
Installation is carried out in the reverse order of removal.
