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
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
