TRANSMISSION Ch 2 page 246 12. Check required rolling torque of pinion bearing 3.5 Nm to 4.5 Nm. If the required rolling torque is not achieved, replace the disk as specified below: • In case of an insufficient rolling torque, install a thinner shim. • In case of an excessive rolling torque, install a thicker shim. When assembling new bearings try to achieve the upper value of the rolling torque. Figure 802 Adjusting differential bearing rolling torque and backlash. 13. Differential bearing rolling torque and backlash result from crown wheel deviation. See table below for the corresponding thickness of the shims. Read crown wheel deviation behind installation dimension 106 [mm] (1).
Crown wheel deviation = e. g. “-10” = -0.10 mm. If no deviation is indicated, the deviation is equal to the value Figure 803 14. Insert the shim determined for backlash on the differential cage side into the bearing hole. 15. Insert bearing outer ring until contact is obtained.
