PUMP GP-HYD 10R2463 - Caterpillar

1. Remove four bolts (1), washers and 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 or tightened.
2. Loosen the track as follows:a. Turn 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 (4) one turn counterclockwise to permit grease to be released from the vent hole below the fill valve. If the track does not loosen, start the machine and move it forward and backward. If the track does not loosen go to Step c. c. Install slug (5) that is 76.2 mm (3 in) in diameter and 63.50 mm (2.5 in) long between the track and sprocket segment. Move the machine in reverse, so the track will be pushed up by the slug. 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 Tooling (A) as shown. Make sure the end of the hydraulic jack is in contact with the flat part of the grouser shoe.4. Lift track with Tooling (A) until the track is off of carrier roller (6). 5. Loosen two bolts (7) and remove carrier roller (6). The weight of the carrier roller is 20 Kg (45 lb). The following steps are necessary for the installation of the carrier roller. 6. Install carrier roller (6) on the machine and tighten two bolts (7).7. Remove Tooling (A).8. Make an adjustment to the track. See the topic "Adjustment Of Tracks" in the module.Disassemble & Assemble Track Carrier Roller
