3 Series E30 324td (M21) SAL
Install an output flange on the side opposite the crown wheel.
Determine friction torque using a bracket with welded on nut (in-
house manufacture) and special tool 00 2 000 (friction torque
gauge).
Turn friction torque meter at speed of approx. 50 rpm.
The friction torque specified in the final drive housing bearing table
should be reached, but not exceeded (refer to Technical Data).
If new shaft seals have already been fitted, 20 Ncm must be
added to each seal in which an output shaft rotates during the
measurement process.
refer to Technical Data
If the given friction torque is not reached, even though both
bearing caps are tightened to the correct tightening torque
(refer to Technical Data),
install a thinner shim opposite the crown wheel and repeat the
measuring procedures.
If the friction torque is reached, even though the second bearing
cap has not yet been tightened to the correct thightening torque
(refer to Technical Data),
a thicker shim must be used on the crown wheel end and the
measuring procedures repeated.
