Drive pinion, adjusting


Notes:

Before adjusting drive pinion, adjust ring gear
(determine total shim thickness "S" total" for
adjustment shims "S1" + "S2") page 39
-186
.

Drive pinion only has to be adjusted again if
gear set, tapered roller bearings for drive pinion
or final drive housing was replaced. Adjustment
overview page 39
-170
.

Do not grease new tapered roller bearings
additionally for friction torque measurement.
The bearings are already greased with a
special oil from the factory.

Determining Shim "S3"
(adjust preload of tapered roller bearing for drive
pinion)

- Clamp final drive into engine and transmission
assembly stand page 39
-123
.

Note: - Pull large tapered roller bearing outer race into housing.

- Pulling small tapered roller bearing outer race into housing.
- The outer race must be oiled and installed using VW408A punch and
30-205 thrust pad.

WARNING!
Wear protective gloves!
Notes: - Install drive pinion without spacer sleeve.
-
Heat up small tapered roller bearing inner race to approx. 100 C and
position on drive pinion.
Do not grease new tapered roller bearings additionally for friction
torque measurement. The bearings are already greased with a special
oil from the factory. Only install spacer sleeve if friction torque has been adjusted (Shim
S3 already determined).

- Install 3304 retainer using two hex bolts M8 x 30.
- When tightening nut, support final drive (e.g. using VAG1359/2
universal mount with VAG1383A transmission hoist).
- Always replace drive pinion nut.
- Tighten nut for drive pinion until no more drive pinion backlash is
present.
- Increase tightening torque further until specified friction torque is
attained; while tightening measure friction torque multiple times.
