Start By:a. remove undercarriage frame assembly
Typical Example
Typical Example1. Put an alignment mark on the swing gear and bearing and the undercarriage frame assembly for assembly purposes. Using tooling (B) and the appropriate size socket, remove bolts (2) and the spacers that hold swing gear and bearing (1) to the undercarriage frame assembly.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 frame assembly can be used to install tool (A).3. Remove the swing gear and bearing. The weight of the swing gear and bearing is 171 kg (376 lb).
Typical Example4. 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 the inner races of the swing gear and bearing.6. 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. 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) in the outer race to determine the required length. Cut the new seal approximately 1 cm (.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. Make sure to put adhesive on the 90° cross section of the seal. Install the seal with the lip facing as shown in Illustration C30014P1.9. Install a new dust seal (4) in the inner race. Follow the same procedure as in Steps 7 and 8.10. Lubricate the swing gear and the bearing with grease. 11. Clean the mating surfaces for the swing gear and bearing on the undercarriage frame assembly. Put 1U8846 Gasket Maker on the mating surface. Fasten tool (A) and a hoist to swing gear and bearing (1), and put it in position on the undercarriage frame assembly. Be sure the stamp mark "S" on the inner race is positioned as shown, relative to the undercarriage frame assembly and the stopper on the outer race.12. Put a thin coat of 2P2506 Thread Lubricant on the threads of bolts (2). Install the spacers and bolts (2) that hold the swing gear and bearing to the undercarriage frame assembly. Tighten the bolts to a torque of 270 40 N m (200 30 lb ft). If desired, tooling (B) can be used to tighten the bolts.End By:a. install undercarriage frame assembly
