Determining Circlips For Input Shaft Ball Bearing

Determining circlips for input shaft ball bearing, 01X, 6 Spd. M/T FWD
It is necessary to readjust input shaft when:
^ Transmission housing

or the

^ Input shaft

are replaced.

Special tools, testers and auxiliary items required

Drift sleeve 30 - 100:

Door hinge alignment tool (M8 and M10) 3114/2:

Fitting tool T10246:

^ Digital depth gauge e.g. VAS 6087

Determining thickness for circlip behind input shaft ball bearing





- Install provisional circlip - arrow - in rear groove on input shaft.
- Push ball bearing onto input shaft.
Installation position:
The sealed side of ball cage faces transmission housing.





- Pressing in ball bearing:
Screw pin (M8 and M10) 3114/2 into tapped hole for ball head stud.
Slide thrust plate T10246/2 onto input shaft.
Position fitting tool T10246/1 behind splines for clutch plate. Tighten bolts - a - only slightly. The bolts locate in recesses in thrust plate T10246/2.
Press in ball bearing onto stop by tightening bolts alternately (1/2 turn at a time).





- Install dished spring - 1 -.
Installation position:
The convex side faces guide sleeve - 2 -.
- Install a shrink hose onto input shaft splines.
- Bolt guide sleeve to transmission housing - 2 -with bolts - 3 -.
- Turn transmission housing so joint flange for bearing housing points upward.
^ The contact surface must be cleaned to remove sealing paste.





- Place thrust washer - 1 - for 4th and 5th speed selector gears onto input shaft.
- Place a digital depth gauge (e. g. VAS 6087) onto thrust washer and measure distance to contact surface of housing. The measuring point on housing contact surface must be as close to input shaft as possible.

Note:
^ When measuring, lift the input shaft with e.g. support bridge 30-211A or the help of a second mechanic until the play in the bag bearing is taken up.
Specification: distance a = 164.14 mm

Note:
^ If the measured value exceeds the specification, use a thinner circlip than the circlip installed so that the specification is attained.
^ If the measured value is below the specification, use a thicker circlip than the circlip installed so that the specification is attained.
^ Determine the circlip thickness to meet the specification as exactly as possible (164.14 mm).

The following circlips are available:





- Select circlip from table.





Checking adjustment and checking distance "a"
^ Determined circlip is installed.
The distance "a" should be 164.14mm + - 0.04 mm if the correct circlip has been selected.

Determining thickness for circlip in front of the input shaft ball bearing
- Drive rear circlip (as determined) and ball bearing onto input shaft using drift sleeve 30 - 100.





- Determine thickest circlip which will still fit.
- Refer to table to determine correct circlip. For part numbers refer to Parts catalog.
