HOUSING 2033806 - Caterpillar

There is a track guide on each side of the machine. The procedure which follows is for the removal and installation of the track roller with the guide.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 the relief valve for the track adjuster 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. Adjust the height of tooling (A) so when it is installed under the frame of the machine, there is enough clearance provided for removal of any one of the track rollers.3. Lift the side of the machine, and install tooling (A) under the frame as shown. 4. Loosen the four bolts that hold track guide (1) to the track roller frame. Do not remove the bolts at this time.5. Fasten a hoist to tool (B), and put it in position under track guide (1) a shown. Remove the bolts that hold the guide; then remove the guide. 6. Loosen the four bolts that hold track roller (2) to the track roller frame. Do not remove the bolts at this time.7. Fasten a hoist to tool (B), and put it in position under track roller (2) as shown. Remove the bolts that hold the track roller; then remove the roller. The weight of the roller is 34 kg (75 lb). The following steps are for the installation of the track roller.8. Be sure the mounting surfaces on the track roller, the guide and the track roller frame are clean and free of dirt and debris prior to installation of the track roller and guide.9. Put track roller (2) in position on the track roller frame with tool (B). Be sure the fill plug on the roller is facing out. Install the four bolts that hold the roller in position. Tighten the bolts to a torque of 245 29 N m (180 22 lb ft).10. Put track guide (1) in position on the track roller frame with tool (B). Install the four bolts that hold the guide.11. Prior to lowering the machine to the ground and tightening the track, be sure all of the track rollers rotate smoothly by hand.12. Lift the machine off of tooling (A), and remove the stands from under the machine. Lower the machine to the floor.13. Tighten the tension of
