Typical Example
Typical Example1. Put an alignment mark on the swing gear and bearing and the track roller frame for assembly purposes. Using tooling (B) and the appropriate size socket, remove thirty four bolts (2) and the spacers that hold the swing gear and bearing (1) to the track roller frame.2. Fasten tool (A) and a hoist to the swing gear and bearing as shown. Bolts and spacers used to hold the upper structure to the undercarriage can be used to install tool (A).3. Remove the swing gear and bearing. The weight of the swing gear and bearing is 347 kg (765 lb). 4. Tape over the sealing surfaces of the dust seals, the inner race and the outer race. This will prevent cleaning solvent from entering the cross sections of the dust seals. Thoroughly clean the swing gear and bearing.5. Remove dust seals (3) and (4) from the outer and inner races of the swing gear and bearing.6. Clean the sealing grooves of the inner and outer races with fine grit sandpaper; then use a cleaning solvent to clean the seal grooves. Be sure the seal grooves are thoroughly clean and dry prior to installing new dust seals. The following steps are for the installation of the swing gear and bearing.7. Lay a new dust seal (3) around the outer race to determine the required length. Cut the new seal approximately 1 cm (0.3937 in) shorter than the required length. Cut the seal at a 90° angle. Use a file to smoothen the cross section cut of the seal.8. Install new dust seal (3) in the outer race using 8T9021 Adhesive. Be sure to put adhesive on the 90° cross section cut in the seal. Install the seal with the lip facing as shown in Illustration C30014P1.9. Install a new dust seal in the inner race. Follow the same procedure as in Steps 7 and 8.10. Lubricate the swing gear and bearing with grease.11. Clean the mating surface for the swing gear and bearing on the track roller frame. Put a bead of 3S6252 RTV Silicone Adhesive/Sealant on the mating surface. Fasten tool (A) and a hoist to swing gear and bearing (1), and put it in its original position on the track roller frame.12. Put a thin coat of 5P3931 Anti-Seize Compound on the threads of thirty four bolts (2). Install the thirty four spacers and bolts (1) that hold the swing gear and bearing to the track roller frame. Tighten the bolts to a torque of 785 78 N m (580 58 lb ft). If desired, tooling (B) can be used to tighten the bolts.End By:a. install undercarriage
