Drive pinion, adjusting


Note:

Before adjusting drive pinion, adjust ring gear
(determine total shim thickness "S
total
" for
shims "S1" + "S2") Page 39
-163
.

The drive pinion only has to be readjusted if the
final drive set (ring gear and drive pinion), the
tapered roller bearings for the drive pinion or
the final drive housing are replaced. Adjustment
overview Page 39
-150
.

Do not additionally oil new tapered roller
bearings for friction torque measurement. The
bearings have already been treated with a
special oil by the manufacturer.

Determine thickness of shim "S3"
(Setting preload of tapered roller bearings for
drive pinion)

- Mount final drive onto engine and transmission
support Page 39
-108
.

- Pull outer race of large tapered roller bearing into housing (without
shim).

- Pull outer race for small tapered roller bearing into housing.
- Lubricate outer race with oil and fit using press tool VW 408 A and
thrust plate 30-205.

CAUTION!
Wear protective gloves.
Note: - Insert drive pinion without spacer sleeve.
-
Heat inner race for tapered roller bearing to approx. 100 C and fit onto
drive pinion.
Do not additionally oil new tapered roller bearings for friction torque
measurement. The bearings have already been treated with a special
oil by the manufacturer. Only install spacer sleeve for final friction torque measurement (after
determining shim "S3").

- Secure retainer 3304 with two M8 x 30 hex 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, unti specified friction torque is obtained.

The following friction torques should be set: 1) run at least 50 km (30 miles) A - Torque gauge, commercially available, 0-600 Ncm
B - Extension with 32 mm socketNew bearings

- Set adjustment ring of universal mandrel VW 385/1.
Distance a = 60 mm
- Set sliding adjustment ring.
Dimension b = 55 mm

- Assemble universal mandrel as illustrated:
Dial gauge extension VW 385/15 = 9 mm long
- Set universal master gauge VW 385/30.
Ro = 57.50 mm
- Set dial gauge (3 mm measuring range) to "0" with 2 mm preload.
