3 Series E36 Z3 (M52TU) ROADST
The axial preload force of the differential housing bearing (4000
N) can be determined from the friction torque,
refer to Technical Data 33 11 2AZ.
Tighten bolts of second bearing cap uniformly only enough, that
the differential can still be turned easily.
On the side tightened down to Tightening Torque, install an output
flange and determine friction torque by means of a bracket with
welded nut (in-house manufacture) and special tool 00 2 000.
Turn friction torque meter at speed of approx. 50 rpm.
The friction torque level indicated in the final drive bearing table
should be achieved, but should not be exceeded,
refer to Technical Data.
If new shaft seals have already been installed, 20 Ncm must be
added for each seal in which an output shaft runs while
measuring.
If the specified friction torque is not achieved, although both
bearing covers are tightened down to specified Tightening Torque,
refer to Technical Data 33 11 2AZ.
a thinner shim must be installed on the side facing the crown
wheel and the measurement must be repeated.
