Adjusting the Track Tension
There should be 7 cm (2-3/4 inches) between the tension nut
and the back of the tension tube (
Figure 46 ). If not, adjust
the track tension using the following procedure:
Figure 46
1. 7 cm (2-3/4 inches)
1. Lower the loader arms, shut off the engine, and remove
the key.
2. Lift/support the side of the unit to be worked on so
that the track is off the ground.
3. Remove the locking bolt and nut ( Figure 47 ).

4. Using a 1/2 inch drive socket wrench, turn the
tensioning screw counter-clockwise until the distance
between the tension nut and the back of the tension
tube (
Figure 46 ) is 7 cm (2-3/4 inches).
5. Align the closest notch in the tension screw to the
locking bolt hole and secure the screw with the locking
bolt and nut (
Figure 47 ).
6. Lower the traction unit to the ground.
Replacing the Tracks
When the tracks are badly worn, replace them.
1. Lower the loader arms, shut off the engine, and remove
the key.
2. Lift/support the side of the unit to be worked on so
that the track is 7.6 to 10 cm (3 to 4 inches) off the
ground.
3. Remove the locking bolt and nut ( Figure 47 ).
4. Using a drive socket wrench (1/2 inch), release the
drive tension by turning the tensioning screw clockwise
(
Figure 47 and Figure 48 ).

5. Push the tension wheel toward the rear of the unit to
move the tension tube against the frame (
Figure 48 ).
(If it does not touch the frame, continue turning the
tensioning screw until it does.)
6. Begin removing the track at the top of the tension
wheel, peeling it off the wheel while rotating the track
forward.
7. When the track is off the tension wheel, remove it from
the drive sprocket and road wheels (
Figure 48 ).
8. Beginning at the drive sprocket, coil the new track
around the sprocket, ensuring that the lugs on the track
fit between the cogs on the sprocket (
Figure 48 ).
9. Push the track under and between the road wheels
(
Figure 48 ).
10. Starting at the bottom of the tension wheel, install the
track around the wheel by rotating the track rearward
while pushing the lugs into the wheel.
