ENGINE AR-COMPLETE 2664379 - Caterpillar

1. Put the machine on a flat level floor.
The grease in the track adjusting cylinder is under high pressure. Grease coming out of the relief valve of the track adjuster, which is under high pressure, can penetrate the body causing personal injury or death. When loosening the tension on the track, loosen the relief valve only one turn. Do not visually inspect the relief valve to see if grease is being released from the track adjuster. Instead, watch the track to see if it loosens. If the track does not loosen after opening the relief valve, move the machine forward and backward to release the tension.
2. Release the tension on the track. Loosen relief valve (1) only one turn. If the track does not loosen after opening the relief valve, move the machine forward and backward until the tension is released. 3. Using Tooling (C), remove eight bolts (2) that hold two track shoes (3) located directly above the master pin.4. Fasten a hoist to each track shoe (3), and remove them from the track assembly. The weight of each track shoe is 27 kg (60 lb). 5. Move the track assembly until the master pin is in a position between the center track carrier roller and the rear track carrier roller. During removal of the master pin with Tooling (A), use a 5F-9455 Pilot Pin (4) to replace the master pin. The 5F-9455 Pilot Pin is part of the 5P-2380 Master Pin Press Arrangement.6. Use Tooling (A) to remove the master pin from the track assembly. Make sure the pilot pin is installed correctly in the track assembly prior to removing Tooling (A). 7. Start the machine, and move pilot pin (4) to the position shown at the rear of the machine.8. Move the machine to the rear onto Tool (B) just enough to take the load off of pilot pin (4).9. Remove pilot pin (4) from the track assembly.10. Move the machine forward to clear the track assembly from the track roller frame assembly.11. Remove the washers and spacers from the track assembly at the master pin joint.12. Fasten a hoist to the rear of the track assembly. Raise the track assembly, and remove Tool (B). Lower the rear of the track assembly to the floor.Connect Track Assemblies
1. Install Tooling (A) in the track link and on the final drive sprocket as shown.2. Start the machine. Move the machine forward until the track assembly is pulled up on the final drive sprocket and the end of the track assembly is forward of a vertical centerline through the center of the sprocket. Remove Tooling (A). 3. Install Tool (B) between the first bushing in the track link and the rear carrier roller.4. Move the final drive sprocket forward. Use Tool (B) to guide track assembly (1) over the track carrier rollers and the front idler. 5. Fasten a hoist to the front of the track assembly, and raise it. Put Tool (D) in position under the track
