Adjusting Track
Tension
1. Loosen the rear idler wheel
adjusting bolt jam nuts.
739-636B
 NOTE: To ensure proper track
tension adjustment, perform all
adjustments on both sides of
the snowmobile.
2. If the deflection (distance
between the bottom of the wear
strip and the inside of the track)
exceeds specifications, tighten the
adjusting bolts to take up exces-
sive slack in the track.
3. If the distance between the bot-
tom of the wear strip and the
inside surface of the track is less
than specified, loosen the adjust-
ing bolts to increase the slack in
the track.
4. Check track alignment (see Track
Alignment section).
5. When proper track tension is
obtained, tighten the adjusting
bolt jam nuts against the axle
housings.
 NOTE: Since track tension and
track alignment are interrelated,
always check both even if only
one adjustment seems neces-
sary.
