is applied to the track span. Adjust the torque on
the tensioning bolt as needed.
6. T ighten the jam nut.
7. T ighten the clamp bolts and torque to 102 N∙m
(75 ft-lb).
Replacing the T racks
When the tracks are badly worn, replace them.
1. Park the machine on a level surface, engage
the parking brake (if applicable), and lower the
grinder .
2. Shut of f the engine and remove the key .
3. Lift and support the side of the unit to be worked
on so that the track is 7.6 to 10 cm (3 to 4
inches) of f the ground.
4. Back out the tensioning bolt and jam nut ( Figure
43 ).
5. Loosen the clamp bolts ( Figure 43 ).
6. Push the front road wheel rearward as far as it
can goes ( Figure 44 ).

7. Begin removing the track at the top of the front
road wheel, peeling it of f the wheel while rotating
the track forward.
Note: Y ou may need to remove the front,
outside road wheel. T o remove it, remove the
snap ring and cap from the center of the road
wheel ( Figure 45 ). Next remove the bolt and
gasket from the center of the wheel and pull the
wheel of f the machine.

8. When the track is of f the road wheel, remove it
from the machine ( Figure 44 ).
9. Beginning at the drive wheel, coil the new track
around the wheel, ensuring that the lugs on
the track t between the spacers on the wheel
( Figure 44 ).
10. Push the track under and between the rear and
center road wheels ( Figure 44 ).
1 1. Starting at the bottom of the front road wheel,
install the track around the wheel by rotating
the track rearward while pushing the lugs into
the wheel.
12. If you removed the front, outside road wheel,
install it at this time using the bolt and gasket
removed previously . T orque the bolt to 102 N∙m
(75 ft-lb) and then clean, grease, and install the
cap and snap ring as instructed in the Checking
and Greasing the Road Wheels ( page 33 ) .
13. Install the tensioning bolt and jam nut.
14. T orque the tensioning bolt to 32.5 to 40 N∙m (24
to 30 ft-lb) to tighten the track.
15. Ensure that the track deects 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.
16. T ighten the jam nut.
17. T ighten the clamp bolts and torque to 102 N∙m
(75 ft-lb).
18. Lower the machine to the ground.
19. Repeat the procedure to replace the other track.
