MAINTENANCE
Track Alignment
NOTE: Track alignment affects track tension.
Misalignment of the track will cause excessive wear
to the track, rail slides, and rail.
NOTE: Excessive rail slide wear occurs due to
running in inadequate snow conditions.
Periodically check that the track is centered and running evenly
on the slide rails. Misalignment will cause excessive wear to the
track and slide rails.
1. Safely lift and support the rear of the snowmobile off the
ground.
2. Rotate the track by hand to check for any possible damage.
3. Inspect the track rods (A) carefully and examine the track
along the entire length of each rod, bending the track edge
and inspecting it for breakage. If any rod damage is found,
the track should be replaced.
4. Warm up the track by starting the engine and apply a small
amount of throttle so the track runs slowly at least five
complete revolutions.
5. Stop the engine and turn the ignition off.
6. Inspect track alignment by carefully looking through the
track window (B) to make sure the rails (C) are evenly
spaced on each side.
7. If the track runs to the left, loosen the left locknut and
tighten the left adjusting bolt (D). If the track runs to the
right, loosen the right locknut and tighten the right adjusting
bolt. It may be necessary to check this with the engine
rotating the track. Be sure to SHUT THE MACHINE OFF
before making any further adjustments.
8. Loosen up the rear idler shaft (F).
9. After any adjustments are complete, be sure to torque the
locknuts (E) to 35 ft-lb (48 N-m).
10. Torque both idler shaft bolts (F) to 35 ft-lb (48 N-m).

WARNING
Broken track rods can cause a rotating track to come off
the machine. Never operate or rotate a damaged track
under power with a broken rod. Serious injury or death
may occur.
WARNING
When performing the following checks and
adjustments, stay clear of all moving parts to avoid
personal injury. Never make any adjustments with the
engine running, as serious personal injury can result.
