Replacing Narrow-Width Tracks
Replace the tracks when they are badly worn.
Note:
You have narrow-width tracks if the tracks are less
than 15.5 cm (6 inches) wide.
1.
Park the machine on a level surface, engage the parking
brake, and lower the loader arms.
2.
Shut off the engine and remove the key.
3.
Lift/support the side of the machine that you will work
on so that the track is 7.6 to 10 cm (3 to 4 inches) off
the ground.
4.
Remove the locking bolt and nut (
5.
Using a 1/2-inch drive ratchet, release the drive tension

Loosen the rear bolt, near the drive wheel (
).
Note:
This enables the drive wheel to pivot forward
and release the tension of the track. If it does not
pivot, turn on the engine and briefly move the traction
control forward.
7.
Remove the track at the top of the front wheel, peeling
it off the wheel while rotating the track forward.
8.
When the track is off the front wheel, remove it from
the drive sprocket and road wheels (
9.
Beginning at the drive sprocket, coil the new track
around the sprocket, ensuring that the lugs on the track
fit between the spacers on the sprocket (
10.
Push the track under and between the road wheels
(
).
11.
Starting at the bottom of the front wheel, install the
track around the wheel by rotating the track rearward
while pushing the lugs into the wheel.
12.
Using a 1/2 inch drive ratchet, turn the tensioning
screw counter-clockwise until the tensioning screw
bottoms out (

14.
Torque the rear bolt to 108 to 122 N∙m (80 to 90 ft-lb).
15.
Lower the machine to the ground.
16.
Repeat the procedure to replace the other track.
17.
Drive the machine, then park the machine on a level
surface, engage the parking brake, shut off the engine,
and remove the key.
18.
Verify that the tension screw is bottomed out.
Note:
The track tension loosens after some use.
19.
Adjust the track tension so that the tension block aligns
with the green guide on the decal or is 1.3 cm (1/2
inch) away from the rear of the tension tube slot; refer
to
Adjusting the Track Tension (page 39)
