Fig. 9 Pressing in outer race for small tapered roller bearing
- Lubricate outer race with oil and fit using press tool VW 408 A and
thrust plate 30-205.

CAUTION!
Wear protective gloves. Fig. 10 Pressing on small tapered roller bearing inner race
- Insert drive pinion with new spacer sleeve.
-
Heat inner race for small tapered roller bearing to approx. 100 C and
fit onto drive pinion. - Press up drive pinion and insert bearing with thrust plate 40-21 onto

Note:
If the specified friction torque is exceeded, the spacer sleeve must be
replaced and the adjustment repeated. A spacer sleeve which has been
compressed too much cannot be reused. Fig. 11 Tightening nut for drive pinion and measuring friction
torque
- Secure retainer 3304 with two M8 x 30 hexagon bolts.
- Support final drive when tightening nut (e.g. using universal support
V.A.G 1359/2 in conjunction with transmission jack V.A.G 1383 A).
- Fit a new drive pinion nut.
- Tighten drive pinion nut just far enough so that no play can be felt at
drive pinion.
- Gradually increase tightening torque, checking friction torque at regular
intervals, until specified friction torque is obtained Fig. 12
