Note: Lubricate the bore for O-ring seal (2) lightly with the lubricant that is being sealed.
Note: Preload the pinion bearings so that initially a torque that is higher than 4 N·m (35 lb in) is required to rotate the pinion. Rotate the pinion several times at the higher torque setting, and then preload pinion bearings so that a torque of 4 N·m (35 lb in) is required to rotate pinion. O-ring seal (2) is not to be installed until after adjustment is made.
Note: Lubricate seal assembly (4) lightly with the lubricant that is being sealed.
(5) Torque for 16 bolts ... 270 ± 40 N·m (200 ± 30 lb ft)
Note: Apply 7M-7456 Compound to the threads of the bolts (5) .
(6) Shims
Note: Use shims (6), as needed.
(BB) Dimension ... 85.17 mm (3.35 inch)
Note: Dimension (BB) can be expected after pinion bearing preload had been adjusted accordingly.
(CC) Dimension ... 192.5 mm (7.58 inch)
(8) 9M-5874 Shim Pack
- Total length ... 3.302 mm (0.13 inch)
- ten shims ... 0.076 mm (0.003 inch)
- 20 shims ... 0.127 mm (0.005 inch)
- ten shims ... 0.076 mm (0.003 inch)
Note: Use shims from shim pack (8) as needed.
(9) Torque for two bolts ... 100 ± 20 N·m (74 ± 15 lb ft)
Assembly of the Differential Group
- Prior to assembling the differential group, assembly the ring gear housing.
- Ream one hole to 19.05 ± 0.013 mm (0.75 ± 0.0005 inch) by using the ring gear as a guide.
- Install one bolt, then ream the 13 remaining holes to 19.05 ± 0.013 mm (0.75 ± 0.0005 inch).
- Tighten 14 nuts (1) to a torque of 440 ± 40 N·m (325 ± 29.5 lb ft).
Gear Adjustment
- After assembly of the differential group into the carrier assembly, support carrier assembly with axle centerline in the vertical position with cone and cup in lower position.
- Adjust cone and cup for 0.41 ± 0.13 mm (0.0161 ± 0.005 inch) backlash of pinion with bevel gear, then adjust cup and cone to preload bearing by increasing dimension (DD) from 0.64 mm (0.02520 inch) to 0.76 mm (0.02992 inch).
- Rotate ring gear in each direction for several revolutions.
- Decrease dimension (DD) to zero and then increase dimension (DD) to 0.51 ± 0.05 mm (0.0201 ± 0.002 inch).
- Recheck gear set backlash and adjust, if necessary by rotating adjusting nuts equal amounts.
