Manual Extract: Differential bearing preload determination
Align the reference marks and mount the bearing support caps;
– mount the cap retaining screws and tighten to the prescribed tightening torque;
– screw on both the ring nuts by hand until there is no play in the bearings;
– as described previously, check that the clearance between the crown wheel and pinion falls within the prescribed values:
pinion–crown wheel clearance
see value engraved on the crown wheel
– otherwise, adjust the clearance using the adjustment ring nuts;
– use a suitable tool to check that the rolling torque falls within the prescribed values: Rolling torque for crown wheel and pinion bearings
5,0÷5,5 Nm (3.687–4.056 lb ft)
(including pinion and transmission)
– the rolling torque can be corrected by turning both the adjustment ring nuts by the same number of notches;
– in particular:
– unscrew the ring nuts to decrease the torque;
– screw on the ring nuts to increase the torque.
