Adjusting the Track Tension
If you place the tab of the tensioning tool along the
rear edge of the tension nut, the other end of the
tensioning tool should align with the edge of the
tension arm as shown in
not correct, adjust the track tension using the following
procedure:
Note:
If the tensioning tool is not available, the
distance between the nut and edge of the tension arm
should be 7.1 cm (2-13/16 inches).

1. Park the machine on a level surface, move
the motion-control levers to the N
position, engage the parking brake, and lower
the hopper.
2. Shut off the engine, and remove the key. Allow
the engine to cool.
3. Clean the tracks with high-pressure water.
Important:
Ensure that you use
high-pressure water to wash only the track
area. Do not use a high-pressure washer
to clean the rest of the machine. Do not
use high pressure water between the drive
sprocket and the machine or you may
damage the motor seals. High-pressure
washing can damage the electrical system
and hydraulic valves or deplete grease.

4. Raise the machine so that the tracks are off the
ground.
5. Clean the drive sprocket, the front wheel, and
the road wheels. The road wheels should spin
freely when clean.
6. Remove the bolt (1/4 x 1-5/8 inches), spacer,
and nut (Figure
7. Turn the tensioning bolt to adjust the distance
between the tension nut and the end tangent
of the tension tube until the distance is correct,
as shown in
8. Align the closest notch in the tensioning bolt to
the bolt hole and secure the tensioning bolt with
the bolt (1/4 x 1-5/8 inches), spacer, and nut
(Figure 40).
Replacing the Tracks
Replace the tracks when they are badly worn.
1. Park the machine on a level surface, move
the motion-control levers to the N
position, engage the parking brake, and lower
the hopper.
2. Shut off the engine, and remove the key. Allow
the engine to cool.
3. Lift/support the side of the machine to be worked
on so that the track is 7.6 to 10 cm (3 to 4
g202806
inches) off the ground.
4. Remove the retaining bolt for the tensioning
screw.
5. Release the drive tension by turning the
tensioning screw clockwise
