WARNING!
Wear protective gloves. Fig. 7 Installing large tapered roller bearing inner race onto
pinion shaft
-
Heat bearing to approx. 100 C (212 F), install and press down.

Note:
The marking "Oben" on 3253/4 thrust piece faces the nut of the puller. Fig. 8 Installing large tapered roller bearing inner race onto

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.

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
.
