Remove And Install Track Rollers
a. remove track roller guards
1. Remove cover (1).
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 (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 (3) 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. Lift the machine until the track rollers are off the track. Put tooling (A) or wood blocks in
position under the machine.
4. Remove four bolts and lockwashers (4). Remove track roller (5). Weight is 22 kg (48 lbs).
NOTE: The following steps are for installation of track rollers.
