Final drive set readjusting,
recommended sequence

The following sequence of work is recommended
to save time when the drive pinion and ring gear
have to be adjusted:

1.) Determine total shim thickness "S
total
" for
"S1" +"S2" (sets preload for tapered roller
bearings for differential) from Page 39
-
54
.
2.) Determine total shim thickness "S
total
" for
"S3" + "S4" (sets preload for tapered roller
bearings for drive pinion) from Page 39
-
41
.
3.) Distribute total shim thickness "S
total
" for "S3"
+ "S4" so that the distance from center of ring
gear to face of drive pinion is the same as
distance "R" which was determined during
production from Page 39
-47
.
4.) Distribute total shim thickness "S
total
" for "S1"
+ "S2" so that the specified backlash
between ring gear and drive pinion is
maintained from Page 39
-61
.

Adjustment overview

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