DIFFERENTIAL AND BEVEL GEAR WITH
DIFFERENTIAL LOCK
(8D2800)
MODELS 613BSS AND 613BSNS
Torque for four bearing
cap bolts .......................................... 35037 lb ft (47550 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 ............ 9818 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 (O 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 N-m) If
the nuts are turned the same amount, the free movement
(back-lash) will not change
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
