DIFFERENTIAL ASSEMBLY

Correct rivet head shape

when properly compressed

1. If ring gear was removed from the differential case,

reinstall it at this time. Bolt ring gear to differential
case in two places, 180

apart, before compressing

rivet; this will eliminate ring gear runout. Use a
hydraulic or mechanical press and riveting fixture.
Pressure requirement per rivet is 45-50 tons or
(41-45 metric tonnes).

NOTE: Ring gear and pinion must be replaced as a
matched set only.
2. Press differential bearing cones onto differential

case halves. Place differential bearing cups on

cones during remainder of assembly to prevent
damage of bearings.

3. Apply a small amount of gear lubricant to all mating

surfaces. This will aid in assembly by keeping parts
together and providing initial lubrication.

4. Place differential gear thrust washer and differential

side gear in differential case flange half.

5. Assemble differential pinion mates and differential

pinion mate thrust washers onto differential cross
shaft. Place assembly into differential case flange
half.

6. Place remaining differential side gear and differential

side gear thrust washer in position on differential
pinion mates.

7. Assemble case halves, making sure match marks are

lined up.

8. Install differential case bolts and torque differential

case nuts evenly to 75-90 Lb-Ft (100-120 N-m).
