Adjusting the drive shaft

Adjusting the drive shaft

1. Clamp the drive shaft in the vice with protective jaws.
2. Put the measuring bridge 3167 onto the 3rd gear and position the transmission housing on the special tool via the drive shaft.

A - Measuring bridge 3167





Measuring bridge

3. With a depth gauge, measure the dimension -a- from the housing to the lower drive shaft groove (e.g. dimension a =28.5 mm).





Dimension a

4. With a depth gauge, measure the dimension -b- from the housing to the contact surface of the ball bearing (e.g. dimension b =26.8 mm).





Dimension b

5. Determine dimension x for the thickness of the lower circlip.

Sample calculation of dimension x
x = a - b = 28.5 mm - 26.8 mm = 1.7 mm

6. Determine the thickness of the circlip in accordance with the table.





7. Force circlip and ball bearing onto the drive shaft with the driver sleeve 30-100.
8. Determine and use the thickest circlip that can still be used.

Subsequent work

Subsequent work

1. Assemble transmission.
2. Fill with transmission oil.
3. Remove transmission from assembly support.
4. Install transmission.
