Fig. 9 Installing small tapered roller bearing outer race
- Oil outer race, and position using VW408A punch and 30-205 thrust
pad.
WARNING!
Wear protective gloves. Fig. 10 Installing small tapered roller bearing inner race
- Insert pinion shaft with new spacer sleeve.
-
Heat small tapered roller bearing inner race to approx. 100 C (212 F)
and install onto pinion shaft. - Lift up pinion shaft and press bearing using 40-21 sleeve up to stop.

Note:
If the specified friction torque is exceeded, the spacer sleeve must be
replaced and the adjustment repeated. A spacer sleeve that has been
over-compressed at any time cannot be reused. Fig. 11 Tightening nut for pinion shaft and measuring friction
torque
- Attach 3304 using two M8 x 30 hex-head bolts.
- Final drive must be supported when tightening nut (e.g. using
VAG1359/2 universal transmission attachment in combination with
VAG1383A transmission jack).
- Replace nut for pinion shaft.
- Tighten nut for pinion shaft, until no more play can be felt on pinion
shaft.
- Increase tightening torque until specified friction torque is attained,
measuring friction torque several times during this process Fig. 12
.
