Circlips For Input Shaft Ball Bearing, Determining

Circlips for input shaft ball bearing, determining - 6 Spd. Manual Transmission 02X All Wheel Drive

It is necessary to readjust the input shaft when:

^ Transmission housing

or the

^ Input shaft are replaced.

Special tools, testers and auxiliary items required





^ Replacement stud (M8 and M10) 3114/2





^ Drift sleeve 30 - 100
^ Fitting tool T10246
^ Digital depth gauge e.g. VAS 6087

Determining thickness for circlip behind the input shaft ball bearing





- Install a provisional circlip - arrow - in rear groove on input shaft.
- Then push ball bearing onto input shaft.

Installation position:

The sealed side of the ball cage faces transmission housing.





- Pressing in ball bearing:

Screw replacement stud (M8 and M10) 3114/2 into tapped hole for ball head stud.

Slide thrust plate - A - of fitting tool T10246 onto input shaft.

Position fitting tool behind splines for clutch plate. Tighten bolts - B - lightly. The bolts locate in the recess in the thrust plate - A -.

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 the transmission housing so the joint flange for the 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 the distance to the contact surface of housing. The measuring point on the housing contact surface must be as close to the input shaft as possible.

Note:
^ When measuring, lift the input shaft with e.g. support bridge 30-211A or the help of a second technician until the play in the ball 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 correct circlip has been selected.

Determining thickness for circlip in front of input shaft ball bearing

- Knock 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.
