1. Lay a new dust seal (3) around the outer race in order to determine the required length. Cut the new seal approximately 1.0 cm (0.39 inch) shorter than the required length. Cut the seal at a 90 degree angle. Use a file to smoothen the cross section cut of the seal.

2. Install new dust seal (3) in the outer race by using 8T-9021 Adhesive. Be sure to apply adhesive on the 90 degree cross section cut in the seal. Install the seal so that the lip of the seal is facing in the direction that is shown. Refer to Illustration 1.

3. Follow the procedure in Steps 1 and 2 in order to install a new dust seal (4) in the inner race.

4. Lubricate the swing gear and bearing with 5P-0960 Molybdenum Grease .

Note: Clean the mating surface for the swing gear and bearing on the undercarriage frame assembly.

5. Apply 1U-8846 Sealant on the mating surface for the swing gear and bearing of the undercarriage frame assembly. Fasten Tooling (A) and a suitable lifting device to swing gear and bearing (1), as shown. Refer to Illustration 2. The weight of the swing gear and bearing is approximately 672 kg (1480 lb). Place the swing gear and bearing in the swing gear and bearing's original position on the undercarriage frame assembly. Make sure that the stamped mark "S" on the inner race is in the position that is shown, relative to the undercarriage frame assembly and the stopper on the outer race. Refer to Illustration 3.

6. Apply a thin coat of 4C-5593 Anti-Seize Compound on the threads of bolts (2). Install the spacers and bolts (2) that secure the swing gear and bearing to the undercarriage frame assembly. Tighten the bolts to a torque of 785 ± 79 N·m (580 ± 60 lb ft). If you desire, Tooling (B) can be used to tighten the bolts.

7. Add approximately 40 L (10.6 US gal) of 5P-0960 Molybdenum Grease to the swing gear and bearing after the installation.

End By: Install the undercarriage frame assembly. Refer to the manufacturer's Disassembly and Assembly Manual for the installation of the undercarriage frame.
