(Determine adjustment shim for input shaft)

Special tools, testers and auxiliary items required

• Dial gauge holder (VW 387)

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

• Thrust pad (VW 510)

• Thrust pad (VW 447 i)

• Punch (VW 407)

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

• Transmission support (VW 353)

• Dial gauge

It is only necessary to readjust input shaft if following components are replaced:

• Transmission housing

• Clutch housing

• Input shaft

• Drive gear for 4th gear

or

• Tapered roller bearing

Adjustment overview => [ Adjustment Overview ] Adjustment Overview.

Requirement

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

- Press tapered roller bearing outer race without adjustment shim into clutch housing until stop.





- Install input shaft in clutch housing and install transmission housing. Tighten hex bolts to 25 Nm + an additional 90°.

- Install measuring device and dial gauge into clutch housing (large tapered roller bearing in transmission housing).





- Rotate input shaft before measuring procedure so that tapered roller bearing settles.

- Set dial gauge to "0" with 1 mm preload.

• This procedure must be repeated for each subsequent measurement, otherwise the dial gauge will not return to the initial position.

- Push input shaft in direction of dial gauge in direction of - arrow -.





- Read play on dial indicator and note (example 1.21).

• Dial gauge does not return to initial position.

- Determine thickness of adjustment shim from table => [ Adjustment Shim Table ] , (example 1.175).

- Remove input shaft and press tapered roller bearing outer race out of transmission housing using thrust pad (VW 447 i).

- Press tapered roller bearing outer race together with 1.175 adjustment shim into transmission housing using thrust pad (VW 510 ).

- Install transmission housing and tighten hex bolt to 25 Nm + an additional 90°.

Performing Measurement Check

- Install measuring device and dial gauge.

- Rotate input shaft so that tapered roller bearings settle.

- Press input shaft in direction of - arrow -.





- Bearing play should be min. 0.01 to max. 0.09 mm.

• If the bearing play cannot be measured, but input shaft play is perceptible and the input shaft turns freely, the adjustment is also acceptable.
