2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
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 of the
ground.
4. Back out the tensioning bolt and jam nut (Figure 45).
5. Loosen the clamp bolts (Figure 45).

7. Begin removing the track at the top of the front road
wheel, peeling it off of the wheel while rotating the
track forwards.
Note: You may need to remove the front, outside
road wheel. To remove this wheel, remove the snap
ring and cap from the center of the road wheel (Figure

it at this time using the bolt and gasket removed
previously.
Note: Torque 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 31).
13. Install the tensioning bolt and jam nut.
14. Torque the tensioning bolt to 32.5 to 40 N-m (24 to 30
ft-lb) to tighten the track.

to 3/8 inch) when 20.6 kg (45 lb) of force is applied to
the track span.
Note: Adjust the torque on the tensioning bolt as
