List of adjustments

Note:
If repairs have been carried out on the transmission, it is only necessary to adjust the pinion shaft, ring gear or final drive set if
components have been replaced that have a direct effect on the adjustment of the final drive. Refer to the following table to
avoid unnecessary adjustments:

Final drive gear set, recommended
sequence for re-adjusting


If the pinion shaft and ring gear have to be readjusted, the following
sequence is recommended for maximum efficiency:
Note:

. 1.) Determine total shim thickness Stotal for S1 + S2 (adjusting preload
for tapered roller bearings for differential) Page 39
-58
.
2.) Determine total shim thickness Stotal for S3 + S4 (preload for
tapered roller bearings for pinion shaft) Page 39
-41
.
3.) Distribute total shim thickness Stotal for S3 + S4 so that the
dimension from center of ring gear to face of pinion shaft is the
same as dimension "r" which was determined during production
Page 39

.
4.) Distribute total shim thickness Stotal for S1 + S2 so that the
specified backlash between ring gear and pinion shaft is maintained
