Assemble shim (9) with a thickness that is equal to the gap +0.00 mm to −.05 mm (+0.00 inch −.002 inch).
Use two bolts (7) to install plate (8) and shim (9). Tighten bolts (7) to a torque of 135 15 N m (99.6 11.1 lb ft). Note: Before installation, apply Tooling (D) to the threads of bolts (7).
Repeat Steps 7 and 12 for the remaining planetary gears.
Rotate each planetary gear (1) by hand. Be certain that the movement of each planetary gear (1) is uniform. Second Reduction Planetary Component
Note: Steps 1 through 4 are for the installation of straight roller bearings.
Illustration 5 g01053034
Machined tang (F) of gear that fits between the straight roller bearing assemblies.
Illustration 6 g01053035
Bearing assembly (10) with retaining straps (C).
Illustration 7 g01053037
Illustration 8 g01053041Note: To install the new straight roller bearing, use retaining straps (C) that hold the rollers in place.Note: Do not use the spacer and the snap ring with the new gear and new bearing.
Assemble bearing (10) in gear (11). Retaining straps (C) come off bearing assembly (10) as bearing assembly (10) is installed.
Turn over gear (11) and repeat Step 1 for the other bearing.
Repeat Step 1 and Step 2 for the other planetary gears.
Proceed to Step 10 for final assembly.
Illustration 9 g00531370
Place planetary gears (18) on a suitable bench.
Install retaining ring (24) in planetary gear (18).
Illustration 10 g00531861
Illustration 11 g01058639
Use a suitable press to install cup (26), spacer (16), and cup (15).
Apply clean oil to cone (17), cone spacer (19), and cone (14). Assemble the cones and the cone spacer in planetary gear (18).
Repeat Steps 5 through 8 for the remaining planetary gears.
Place a suitable strap throught the gear and the bearing assemblies. Fasten the strap to a suitable lifting device and position the planetary gear in the carrier. The weight of the gear assembly is appoximately 125 kg (275 lb).
Illustration 12 g01058635
Use a suitable press to install planetary shaft (20). Rotate planetary gear (18) while the planetary shaft is pressed into position. Shoulder (X) of the planetary shaft must be seated against the carrier. Note: The planetary shaft must be installed at room temperature. Do not lower the temperature of planetary shaft (20) before installation.
Repeat Steps 10 and 11 for the remaining planetary gears.
Illustration 13 g01058645
Reposition the carrier.
Use Tooling (B) to measure the gap between counterbore (Y) and planetary shaft (20).
Illustration 14 g01058646
Assemble shim (21) with a thickness that is equal to the gap +0.00 mm to −.05 mm (+0.00 inch −.002 inch).
Illustration 15 g01058647
Use two bolts (22) to install plate (23) and shim (21). Tighten bolts (22) to a torque of 255 15 N m (188.1 11.1 lb ft). Note: Before installation, apply Tooling (D) to the threads of bolts (22).
Repeat Steps 13 and 16 for the remaining planetary gears.
Rotate each planetary gear (18) by hand. Be certain that the movement of each planetary gear (18) is uniform. End By:
Install the rear axle shafts. Refer to Disassembly and Assembly, "Axle Shaft - Install".
Install the carrier of the second reduction planetary component. Refer to Disassembly and Assembly,
