the drive sprocket. The track should flex no more than
1/4 to 3/8 inch (0.6 to 1 cm). If it does, adjust the track
tension using the following procedure:
1. Stop the machine in on a level surface.
2. Stop the engine, lower the grinder, remove the key,
and wait for all moving parts to stop before leaving
the operating position.
3. Loosen the jam nut on the track tensioning bolt and
the clamp bolts on the tension arm (Figure 45).

2. Jam nut
4. Torque the tensioning bolt to 24 to 30 ft-lb (32.5 to
40 N-m) to tighten the track (Figure 45).
5. Ensure that the track deflects less than 1/4 to 3/8
inch (0.6 to 1 cm) when 45 lb (20.6 kg) of force is
applied to the track span. Adjust the torque on the
tensioning bolt as needed.
6. Tighten the jam nut.
7. Tighten the clamp bolts and torque to 75 ft-lb (102
N-m).
Replacing the Tracks
When the tracks are badly worn, replace them.

1. Lower the grinder.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Lift/support the side of the unit to be worked on
so that the track is 3 to 4 inches (7.6 to 10 cm) off
of the ground.
4. Back out the tensioning bolt and jam nut (Figure 45).
5. Loosen the clamp bolts (Figure 45).
6. Push the front road wheel rearward as far as it will
go (Figure 46).
7. Begin removing the track at the top of the front road
wheel, peeling it off of the wheel while rotating the
track forwards.
Note: You may need to remove the front, outside
road wheel. To remove this wheel, remove the snap
ring and cap from the center of the road wheel
(Figure 47). Next remove the bolt and gasket from
the center of the wheel and pull the wheel off of the
machine.
