DIFFERENTIAL SUPPORT CASE INSTALLATION
Support Case and
Differential Assembly
1. Install ring gear support case assembly into carrier
housing. The ring gear side of the support case
must be tipped to clear the pinion roller bearing
retainer plate. Care should be taken to avoid
damage of ring and pinion gear teeth and bearings.
Place bearing cups into position
2. Assemble differential bearing caps. Install bearing
cap bolts (finger tight only). Install adjusting rings.
3. Tighten adjusting ring on back side of ring gear
until there is zero (0) backlash between the ring
gear and pinion.
4. Next, tighten adjusting ring (on the tooth side
of ring gear) until cup is seated. Continue to
tighten adjusting ring until backlash has returned to
measurement taken prior to disassembly.
5. Check ring gear and pinion backlash in four
equally spaced positions around the ring gear with
a dial indicator.
NOTE: If backlash does not vary more than .003 in. and
the average backlash is between .008-.016 in. or (.20-
.40 mm) the setting is acceptable.
6. Once proper backlash is established, torque bearing
cap bolts to:
G Model 220-250 Lb-Ft (298-339 N-m)
M Model 290-350 Lb-Ft (393-475 N-m)
7. Install adjusting ring retainers, washers, and bolts.
Torque retainer bolts to 30-40 Lb-Ft (41-54 N-m).
NOTE: Assemble adjusting rings so that the side with two
shoulders is facing out to ensure clearance for the bearing
(Inside face has only one shoulder). See Figure 11.
