.
Notes:
Tapered roller bearings for differential are low-
friction bearings. Therefore friction torque can
only be used for check measurement in a
limited way. A correct adjustment is only
possible by determining the total thickness
"Sges".
Do not grease new tapered roller bearings
additionally for friction torque measurement.
The bearings are already greased with a
special oil from the factory.
