Replacing the Tracks
When the tracks are badly worn, replace them.
1. Park the machine on a level surface, engage the
parking brake, and lower the hydraulic lift.
2. Shut off the engine and remove the key.
3. 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.
4. Back out the tensioning bolt and jam nut

6. Begin removing the track at the top of the
tensioning wheel, peeling it off the wheel while
rotating the track forward.
7. When the track is off of the tensioning wheel,
remove it from the machine
8. Beginning at the drive wheel, coil the new track
around the wheel, ensuring that the lugs on
the track fit between the spacers on the wheel
(Figure 46).
9. Push the track under and between the rear and
center road wheels
10. Starting at the bottom of the tensioning wheel,
install the track around the wheel by rotating
the track rearward while pushing the lugs into
the wheel.
11. Install the tensioning bolt and jam nut.
12. Torque the tensioning bolt to 32.5 to 40 N∙m (24
to 30 ft-lb) to tighten the track.
13. Ensure that the track deflects less than 0.6 to 1
cm (1/4 to 3/8 inch) when 20.6 kg (45 lb) of force
is applied to the track span. Adjust the torque on
the tensioning bolt as needed.
14. Tighten the jam nut.
