Measuring friction torque
Notes:
Pinion shaft/hollow shaft tapered roller bearings
are low friction bearings. Therefore the friction
torque has only 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 to perform the friction torque
measurement. These bearings have already
been treated with a special oil by the
manufacturer.
Friction torque specification: - Install torque gauge, 0-600 Ncm (53 in. lb) on pinion shaft.
- Read off friction torque.
