DIFFERENTIAL AND CARRIER ASSEMBLY (LOCK TYPE)
14.
Lower the temperature of the large bearing cup
and small bearing cup (17). Install the bearing
cups in housing (18).
15.
Heat larger bearing cone (20) in oil to a
maximum temperature of 275°F (135°C). Install
bearing cone (20) on pinion shaft (19) as shown.
16.
Put pinion shaft in housing (18). Heat small
bearing cone (21) in oil to a maximum
temperature of 275° F (135°C). Install bearing
cone (21) on pinion shaft (19). Apply oil to
bearing cones (20 and 21).
17.
Install nut (23), the lock and nut (22) on pinion
shaft (19). Tighten the nuts until a torque of 6 to
10 lb-in (0.7 to 1.1 N•m) is needed to turn pinion
shaft (19). If pinion shaft does not run in this
torque range, replace bearings.
17A.
Install washer and nut. If new bearings are
being used, tighten nut until a torque of 6 to 10
lb-in (0.7 to 1.1 N•m) is needed to turn pinion
shaft. If used bearings are being installed the
pinion shaft should turn at 3 to 5 lb-in (0.35 to
0.55 N•m). If pinion shaft does not turn in these
torque ranges, replace bearings.
17B.
Peen nut collar into keyway shift 0.1 inch (2.5
mm) deep.
18.
Install spring pin (24) in carrier assembly (25).
19.
Fasten a hoist to carrier assembly (25) and put it
in position on tooling (A) as shown.
