Track Alignment
Check track alignment at the intervals outlined in the periodic mainte-
nance chart beginning on page 50. Make sure the track is centered and
running evenly on the slide rails. Misalignment will cause excessive
wear to the track and slide rail.
1. Support the rear of the
snowmobile slightly off the
ground with an appropriate
snowmobile support.
2. Start the engine and apply a
small amount of throttle
until the track turns slowly
at least five complete revo-
lutions. Stop the engine.
3. Inspect track alignment by
looking through the track
windows to make sure the
rails are evenly spaced on
each side. If the track runs
to the left, loosen the left
idler wheel mounting bolt and tighten the left track adjusting bolt. If
the track runs to the right, loosen the right idler wheel mounting bolt
and tighten the right track adjusting bolt.
4. After adjustments are complete, tighten the locknuts and idler shaft
bolts. Torque to 35-40 ft. lbs. (47-54 Nm).
5. Repeat step 2 to verify proper alignment.
WARNING
When performing the following checks and adjustments, stay clear of all mov-
ing parts to avoid serious personal injury. Make sure the track contains no
objects that could be thrown out while the track is rotating. Keep clear of track.
This includes but is not limited to hands, tools, feet and clothing. Make sure no
one is standing close to the machine while the track is rotating.
