PIPE ASSEM. 5H4035 - Caterpillar

1. Remove four bolts and washers (1) and remove cover (2).
The adjuster cylinder for the track is under high hydraulic pressure. Do not visually inspect the relief valve to see if grease is released when it is open. Look to see that the track has loosened. Use this warning any time the tracks are loosened or tightened.
2. Loosen the track as follows:a. Turn the relief valve (3) one turn counterclockwise to permit grease to be released from the vent hole below the relief valve. If the track does not loosen, go to Step b.b. Turn fill valve one turn counterclockwise to permit grease to be released from the vent hole below the fill valve. If the track still does not loosen, start the machine and move it forward and backward. If grease is still not released, go to Step c.c. Install a slug that is 76.2 mm (3 in) in diameter and 63.5 mm (2.5 in) long between the track and sprocket segment. Move the machine to the rear so the track will be pushed up by the bar. This will put tension on the track and move the front idler and track adjuster to the rear against the force of the recoil spring. This will push grease out of the vent holes. 3. Install tool (A). Make sure the end of the hydraulic jack is in contact with the flat part of the grouser shoe. 4. Lift the track with tool (A) until it is off of the carrier roller. For additional safety, attach hooks to track as shown. 5. Remove two bolts and washers (4). Remove carrier roller (5). The weight is 20 kg (45 lb). The following steps are for installation of track carrier rollers. 6. Put carrier roller (5) in position on the bracket with the dowels in alignment with holes (6). Install two washers and bolts (4) that hold it in position.7. Remove tool (A).8. Make an adjustment to the track. See the topic, Track Adjustment.9. Install cover (2) over the hydraulic track adjuster and secure with bolts (1) that hold it in position.Disassemble Track Carrier Rollers
Start By:a. remove track carrier rollers 1. Remove cover (1) and the gasket from the track carrier roller (2).2. Drain the oil from the roller. 3. Remove two bolts (3). Remove the plate (4). 4. Use tooling (A) to push shaft assembly (6) out of the roller. Remove bearing cone (5) from the roller. 5. Use tooling (B) to remove bearing cups (7) from the roller. 6. Remove spiral snap ring (8) from the shaft. 7. Remove collar (9) and Duo-Cone seals (10) from the shaft. 8. Remove O-ring seal (11) from the shaft. 9. Use tooling (C) to remove bearing cone (12) from the shaft.Assemble Track Carrier Rollers
1. Use tooling (E) and a press to install the bearing cups in the roller. 2. Heat bearing cone (12) to a maximum temperature of 135° C (275° F). Install the cone on shaft (6). 3. Install O-ring
