Output Shaft, Adjusting

Output Shaft, Adjusting

(Determine adjustment shim for output shaft)

Special tools, testers and auxiliary items required

• Dial gauge holder (VW 387)

• Magnetic plate 50 MM dia. (VW 385/17)

• Thrust pad (VW 512)

• Replacement stud (8 MM/10 MM) (3114/2)

• Punch (VW 407)

• Torque wrench 5 to 50 Nm (V.A.G 1331)

• Dial gauge

• - 1 - Internal extractor (Kukko 21/6 )

• - 4 - Counter-support (Kukko 22/2 )

It is necessary to readjust the output shaft when the following components are replaced:

• Gear set

• Clutch housing

or

• Tapered roller bearing

Adjustment overview => [ Adjustment Overview ] Adjustment Overview.

Requirements

• Sealing surfaces of clutch and transmission housings must be cleaned of sealant.

- Press small tapered roller bearing outer race with a 0.65 mm thick shim into clutch housing to limit stop=> [ Pressing in small outer race/tapered roller
bearing ] Output Shaft

- Install output shaft and tighten nuts for bearing mount to 25 Nm + an additional 90°.

- Install dial gauge (3 mm measuring range) and set to "0" with 1 mm preload.





- Move output shaft up and down, read off play on dial gauge and note (example: 0.30 mm).

Shim, Determining Thickness

The specified bearing preload is obtained by adding a constant preload figure of (0.20 mm) to the reading obtained (0.30 mm) and the thickness of the shim installed (0.65 mm).

Example:





- Remove output shaft and pull out small outer race for tapered roller bearing.





A Internal puller 37 to 46 mm, e.g. (Kukko 21/6)
B Support, e.g. ( Kukko 22/2)

The following shims are available:





Different tolerances make it possible to measure the required shim size exactly.

- Press in small outer race/tapered roller bearing with determined shim (1.15 mm in example) and install output shaft. Tighten bearing mount nut in clutch housing to 25 Nm and + an additional 90°.
