Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to the "Tools And Shop Products Guide", NENG2500 for the tools and the supplies suitable to collect and contain any of the fluids in Caterpillar machines. Dispose of the fluids according to local regulations and mandates.1. Remove all of the grease from the swing gear and bearing. Put the grease in a suitable container for storage or disposal. 2. Put an alignment mark on swing gear and bearing (1) and the undercarriage frame assembly for assembly purposes. Fasten Tooling (A) and a hoist to swing gear and bearing (1) as shown. Put slight lifting tension on the swing gear and bearing. 3. Using Tooling (B), remove 38 bolts (2) and the spacers that hold swing gear and bearing (1) to the undercarriage frame assembly.4. Remove swing gear and bearing (1). The weight of the swing gear and bearing is 672 kg (1480 lb). 5. 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.6. Remove dust seals (3) and (4) from the outer and the inner races of the swing gear and bearing.7. Clean the sealing grooves of the inner and the outer races with fine grit sandpaper; then use a cleaning solvent to clean the seal grooves. Make 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.8. Lay a new dust seal (3) around the outer race to determine the required length. Cut the new dust seal approximately 1 cm (.3937 in) shorter than the required length. Cut the dust seal at a 90 degree angle. Use a file to smoothen the cross section cut of the seal.9. Install new dust seal (3) in the outer race using 8T-9021 Adhesive. Make sure to put adhesive on the 90 degree cross section cut in the dust seal. Install the dust seal with the lip facing as shown in illustration C30014P1.10. Install a new dust seal (4) in the inner race. Follow the same procedure as in Steps 8 and 9.11. Lubricate the swing gear and bearing with 5P-0960 Multipurpose Grease. 12.
