Illustration 1	g00827504

(1) Torque for six bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

(2) (9) Use the needed shims at these positions. End play for gear ... 0.10 ± 0.05 mm (0.004 ± 0.002 inch)

Note: See "Procedure to Adjust Lower Transfer Gear Bearings" in this manual.

(3) Torque for six bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

(4) Torque for 12 bolts ... 270 ± 40 N·m (200 ± 30 lb ft)

(5) Torque for one bolt ... 270 ± 40 N·m (200 ± 30 lb ft)

(6) Torque for six bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

(7) Before you install the lip seal, coat the bore. Coat the surface which contacts the retainer. Apply 7M-7260 Liquid Gasket. Allow the gasket material to dry. Do NOT apply gasket material to the lip seal case. Lubricate the seal of the lip with SAE 30W oil.

(8) Torque for six bolts ... 55 ± 10 N·m (41 ± 7 lb ft)

(10) Apply 5P-3931 Anti-Seize Compound on the threads and tighten the nut. Torque for the nut ... 620 ± 60 N·m (450 ± 50 lb ft)

(11) Torque for six bolts ... 135 ± 20 N·m (100 ± 15 lb ft)

(12) Adjust the backlash (free play) between the pinion and the bevel gear. Use needed shims (12). Backlash for pinion gear ... 0.30 + 0.12 − 0.10 mm (0.012 + 0.005 − 0.004 inch)

Note: See "Procedure to Adjust End Play of Bevel Pinion Bearings" in this manual.

Note: Use bolt (A) of an appropriate selection through the case. Tighten the bolt until there is zero end play in the pinion. Position the bevel and transfer gear so that the bevel gear shaft is in the vertical position with the bevel gear at the bottom. Add shims (12) in order to reduce the backlash or remove the shims in order to increase the backlash.

(13) Torque for 12 bolts ... 480 ± 60 N·m (350 ± 40 lb ft)

Procedure to Adjust Lower Transfer Gear Bearings

1. Make sure that the bearing cups and the cones are seated correctly. Use a 0.038 mm (0.0015 inch) shim or use a standard feeler gauge.

2. Assemble the input gear in a vertical position in the case. Install the bearing cage without shims (2) .

3. Install two bolts with two washers on opposite sides of the gear.

4. Torque the bolts to 2.25 N·m (20 lb in).

5. Rotate the input gear for three full turns.

6. Torque the bolts to 4.5 N·m (40 lb in) and repeat Step 5. Torque the bolts to 4.5 N·m (40 lb in).

7. Measure the space between the case and the outside diameter of the bearing cage flange next to each bolt.

8. Add the dimensions from Step 7 and divide by two.

9. Add 0.23 mm (0.009 inch) to the dimension from Step 8.

Note: Repeat Steps 2 through 9 if the dimension from Step 9 is questionable or if the bearing adjustment is questionable. If the second dimension is within 0.05 mm (0.002 inch) of the original dimension, use the smaller dimension.

10. Use needed shims at location (2) in order to equal the dimension from Step 9.

11. Install the components: bearing cage, shims, bolts and washers. Torque the bolts to 135 ± 20 N·m (100 ± 15 lb ft). Check end play with a dial indicator.

Procedure to Adjust the End Play of the Bevel Pinion Bearing

1. Make sure that the bearing cups are seated against the shoulders in the case. Make sure that the bearing cones are seated against the shoulders of the pinion shaft. Use a 0.038 mm (0.0015 inch) shim or use a standard feeler gauge.

2. Place the pinion in a vertical position. Install the cage in the case without shims (12) .

3. Install two bolts with two washers on opposite sides of the gear.

4. Torque the bolts to 4.5 N·m (40 lb in).

5. Rotate the pinion for three full turns.

6. Torque the bolts to 9.0 N·m (80 lb in).

7. Rotate the pinion for three full turns. Torque the bolts again to 9.0 N·m (80 lb in).

8. Measure the space between the case and the outside diameter of the cage. Measure this space by the flange next to each bolt.

9. Add the measurements from Step 8 and divide by two.

10. Add 0.43 mm (0.017 inch) to the dimension from Step 9.

11. Use needed shims at location (12) in order to equal the dimension from Step 10.

12. Install the bolts and install the washers. Torque the bolts to 135 ± 20 N·m (100 ± 15 lb ft). Check end play with a dial indicator.
