- Remove pinion shaft and large tapered roller
bearing outer race and install together with
measured shims S3 and spacer sleeve Page

.
- Install small tapered roller bearing inner race
and tighten nut for pinion shaft until specified
friction torque is obtained Page 39

.
Notes:
Do not additionally oil new tapered roller
bearings for the friction torque measurement.
The bearings have already been treated with a
special oil by the manufacturer.
Increase tightening torque gradually and check
friction torque at regular intervals, 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.
- Adjust to following friction torques:

The ring gear must be adjusted if any of the
components have been replaced table,

Notes:
Differential tapered roller bearings are low
friction bearings. Therefore the friction torque
only has a limited use as a check. Correct
adjustment is only possible by determining the
total shim thickness Stotal.
Do not additionally oil new tapered roller
bearings for the friction torque measurement.
The bearings have already been treated with a
special oil by the manufacturer.
Determining total shim thickness "Stotal" for
shims S1 + S2
(Setting preload of tapered roller bearing for
differential)
Pinion shaft removed or ring gear removed
from differential housing.
- Pry out drive flange seal using pry bar.

Measuring friction torque
Pinion shaft removed
Differential with shims S1* and S2* installed
Friction torque specifications:
Notes: - Install torque gauge, 0-600 Ncm (53 in. lb)-A- onto differential.
- Read value of dial indicator.

150-300 Ncm (13-27 in. lb) 30-60 Ncm (3-5 in. lb)
1) Must have run at least 50 km (30 miles) Differential tapered roller bearings are low friction bearings. Therefore
the friction torque only has a limited use as a check. Correct
adjustment is only possible by determining the total shim thickness
Stotal. Do not additionally oil new tapered roller bearings for the friction
torque measurement. The bearings have already been treated with a
special oil by the manufacturer. If the final drive gear set (pinion shaft and ring gear) is being re-
adjusted, the adjustment of the pinion shaft should be checked
