Replacing Wide-Width Tracks
Replace the tracks when they are badly worn.
Note:
You have wide-width tracks if the tracks are more
than 23 cm (9 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 unit to be worked 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 ( Figure 59 ).
5. Using a 1/2-inch drive ratchet, release the drive tension
by turning the tensioning screw clockwise (
Figure 59
and Figure 60 ).
6. Loosen the rear bolt, near the drive wheel ( Figure 60 ).
7. Remove the nut securing the outer front wheel and
remove the wheel (
Figure 62 ).

8. Remove the track ( Figure 62 ).
9. Pull the 2 large washers out of the outer wheels, 1 on
each side of each wheel (
Figure 62 ).
10. Clean the old grease and dirt out of the area between
where the washers were installed and the bearings
inside the wheels, then fill this area on each side of
each wheel with grease.
11. Install the large washers on the wheels over the grease.
12. Install the new track. ( Figure 62 ).
Note:
Ensure that the lugs in the track fit between the
spacers in the middle of the drive sprocket.
13. Install the outer front wheel and secure it with the nut
removed previously (
Figure 62 ).
14. Torque the nut to 300 ft-lb (407 N∙m).
15. Turn the tensioning screw counter-clockwise until the
tensioning screw bottoms out.
16. Align the closest notch in the tension screw to the
locking bolt hole and secure the screw with the locking
bolt and nut.
17. Torque the rear bolt to 108 to 122 N∙m (80 to 90 ft-lb).
18. Lower the machine to the ground.
19. Repeat the procedure to replace the other track.
20. Drive the machine, then park the machine on a level
surface, engage the parking brake, shut off the engine,
and remove the key.
21. Verify that the tension screw is bottomed out ( Figure
61 ).
Note:
The track tension loosens after some use.
22. 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) .
