SEAL 8C9386 - Caterpillar

Illustration 20 g00491472
Install a new shim pack (17) of the same thickness from step 22 of the disassembly on side gear (16) .Note: Apply a small amount of grease to the shims prior to installation. This will retain the shims in place when the side gear is installed.

Illustration 22 g00491475
Invert side gear (16). Install side gear (16) into the bevel gear, as shown.Note: Turn side gear (16) slowly until the spline engages with the spacer and all five friction discs.

Illustration 25 g00491489
Install Tooling (C) on bevel gear (2) and side gear (16), as shown. This will retain the side gear, the shims, the spacer, and the disc pack in the bevel gear. Install the bevel gear on the differential case.Note: The clamping segment of Tooling (C) must not protrude past the face of side gear (16) .
Illustration 26 g00491494
Install bevel gear (2) into differential case (3) .
Install twelve bolts (1) .
Tighten bolts (1) evenly until bevel gear (2) is seated on differential case (3) .
Remove the nut and the cap of Tooling (C) .
Illustration 27 g00491495
Loosen up the clamping segment of Tooling (C). Remove Tooling (C) from the differential assembly.
Illustration 28 g00491498
Tighten twelve bolts (1) to a torque of 300 40 N m (220 30 lb ft).Note: Steps 25 through 34 are for measuring the end play gap.

Place the differential assembly in the vise.
Install Tooling (A) into the axle shaft boreof the differential assembly. Tooling (A) must pass through the side gear.
Tighten the nut of Tooling (A) enough to lock the tool on the internal shoulder of the side gear. The lever of Tooling (A) must be free to move after the nut is tightened.
Mount Tooling (B) on the differential assembly, as shown. Zero the dial indicator of Tooling (B) on Tooling (A) .
Apply 40 N m (30 lb ft) of torque to Tooling (A). The dial indicator reading is the measured end play gap at the side gear for the side opposite the bevel gear.
Illustration 32 g00491564
Repeat steps 23 through 27. Measure the end play gap at the side gear for the adjacent side of the bevel gear.
Record measurements of the end play gap from side by side of the differential assembly.
The measurement of the end play gap must fall between 0.05 mm (0.002 inch) and 0.15 mm (0.006 inch) in order to meet specifications.
If the measurement of the end play gap is greater than 0.15 mm (0.006 inch) disassemble the differential assembly. Add the necessary shims in order to meet specifications.
If the measurement of the end play gap is less than 0.05 mm (0.002 inch) disassemble the differential assembly. Remove the necessary shims in order to meet specifications.End By: Install the differential. Refer to Disassembly and Assembly, "Differential Axle - Remove and Install".
