- Remove drive pinion and outer race of large
tapered roller bearing and install together with
measured shims "S3" and spacer sleeve from

.
Install inner race of small tapered roller bearing
and tighten nut for drive pinion until specified
friction torque is obtained

.

Note:

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.
Increase tightening torque slowly 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 which has been
compressed too much cannot be reused.

Note:

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
