D3C, D4C AND D5C SERIES II TRACTORS POWER TRAIN Caterpillar


Tracks

Usage:

Separation of Tracks

NOTE: This operation was done on the 931C. The D5C does not have a support bracket.

1. Remove cover (1).

------ WARNING! ------

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.

--------WARNING!------

2. Loosen the track as follows:

a. Turn relief valve (2) 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 slug (4) that is 76.2 mm (3 in) in diameter 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. Start the machine and move split master link (5) to the rear of the machine. Install tool (A) under the grouser of the shoe just under the master shoe. Move the machine slowly backward until the track is tight against tool (A).

4. Remove two bolts (8) that hold the shoe below the master shoe. The bolts must be removed to install the tooling for connection of the tracks.

5. Remove four bolts (6) and remove master shoe (7).

------ WARNING! ------

Keep away from the front and rear of the machine when the track is pushed off of the track carrier roller and idler.

--------WARNING!------

6. Start the machine and drive slowly forward to remove track (9).

Connection Of Tracks

------ WARNING! ------

Keep away from the area behind the sprocket when the track is pulled on the sprocket with tooling (B).

--------WARNING!------

1. Put the machine in position on the track with the sprocket near the end of the track. Install tooling (B) on the track and sprocket as shown. Drive the machine forward and pull the track on to the sprocket with tooling (B) until the track is forward of a vertical center line through the sprocket.

2. Remove tooling (B) and install tool (C) on the track as shown. Fasten a hoist. Move the machine and track forward. Use the hoist and tool (C) as a guide for the track over the carrier roller and idler.

3. Remove tool (C) and install tool (A) under the grouser of the track shoe under split master link (5). Drive the machine forward to tighten the track against tool (A). Make a connection of split master link (5).

4. Put SAE 30W oil on the threads and install bolts (8). Tighten the bolts to a torque of 90 ± 20 N*m (65 ± 15 lb ft). Then, tighten the bolts an additional 120 degrees.

5. Install master shoe (7). Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold the master in place. Install the bolts and tighten to a torque of 90 ± 20 N*m (65 ± 15 lb ft), then tighten the bolts an additional 180 degrees.

6. Make an adjustment to the track. See the topic, Track Adjustment in the Specifications Service Manual.

7. Install the cover over the hydraulic track adjuster.

8. Remove the support bracket. The D5C does not have a support bracket.
