DIFFERENTIAL GROUP
(1) Torque for bolts .......100 ± 15 lb. ft. (136 ± 20 N.m)
DIFFERENTIAL AND BEVEL GEAR WITH
DIFFERENTIAL LOCK
(8D2800)
Torque for four bearing
cap bolts ................................ . 350 ± 37 lb. ft. (475 ± 50 N-m)
(6)
Torque for 12 bolts that hold carrier
to axle housing .......................... 198 ± 9 lb. ft. (269 ± 12 N-m)
(8)
Torque for 12 bolts that hold case
assemblies together ............... 100 ± 10 lb. ft. (135 ± 14 N-m).
(13) Torque for 12 bolts ............ 98 ± 18 lb. ft. (133 ± 24 N-m)
Adjustment Procedure:
1.
Install pinion shaft (4) with bearings in housing (3).
2.
Tighten nut (2) on pinion shaft (4), until torque needed to
turn pinion shaft (4) is ............ 8 ± 2 lb. in. (0.9 ± 0.2 N-m)
3.
Install lock and nut (1).
4.
Install case (9) in carrier (11).
5.
Install pinion shaft (4) and housing (3) into carrier (11).
Use shims (5) to put pinion shaft (4) in alignment with bevel
gear (10).
6.
Make adjustments to nut (12) and nut (7) until free
movement (backlash) between bevel gear (10) and pinion
shaft (4) is .................... .008 to .017 in. (0.20 to 0.43 mm)
7.
Tighten nut (12) and nut (7) the same amount until the
torque needed to turn pinion shaft (4) is 30 to 50 lb. in. (3 to 6
8.
Check free movement (backlash). If an adjustment is
necessary, turn nut (12) and nut (7) the same amount, and
in the same direction until the correct free movement
(backlash) is given. If the nuts are turned the same
amount and in the same direction, the bearing preload will
not change.
