Reassembly of Differential Ring Gear and Bearings

6. Position pinion bearing cage assembly on pinion shaft.

Reassembly of Differential Ring Gear and Bearings

Position outer pinion bearing cone on pinion shaft and

press into place using steel tubing for driver (Fig. 97).

NOTE: Lubricate all differential bearings, gears, and

Driver dimensions are shown in Fig. 92.

thrust washers with SAE 90 EP lubricant, SCL type.

Press differential bearing cones on case halves (Fig.

99). Bearing driver dimensions are given in Fig. 100.

7. Keep pinion and cage assembly in press with

approximately 500 pounds of press pressure exerted

on driver. Wrap several turns of soft wire or cord

around pinion cage and pull in horizontal line with

spring scale. While pulling in straight line, (90 degrees

from centerline of shaft), read spring scale and

measure rotating torque (Fig. 98). Multiply reading on

spring scale by one-half diameter of bearing cage to

obtain preload torque. Correct preload torque is 13 to

23 in. lbs. If preload is not within these limits, remove

shims to increase preload or add shims to decrease

preload.

NOTE: This is a preliminary check. Final bearing

preload check must be made with pinion shaft and

bearing cage assembly in differential carrier housing.

2. Check ring gear mounting surface of flanged half of

differential case for burrs. Remove burrs with file

(Fig. 101).
