Adjusting Track Tension
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments on both sides of the
snowmobile.
1. Loosen the rear idler wheel adjust-
ing bolt jam nuts.
739-636B
NOTE: On the Bearcat XT models,
the rear axle cap screws must also
be loosened.
743-323A
2. If the deflection (distance between
the bottom of the wear strip and the
inside of the track) exceeds specifi-
cations, tighten the adjusting bolts to
take up excessive slack in the track.
3. If the distance between the bottom of
the wear strip and the inside surface
of the track is less than specified,
loosen the adjusting bolts to increase
the slack in the track.
4. Check track alignment (see Track
Alignment sub-section in this section).
5. When proper track tension is
obtained, tighten the adjusting bolt
jam nuts against the axle housings.
NOTE: On the Bearcat XT models,
tighten the rear axle cap screws to
20 ft-lb.
NOTE: Since track tension and
track alignment are interrelated,
always check both even if only one
adjustment seems necessary.

! WARNING
If jam nuts are not tightened properly,
the adjusting bolts could loosen
causing the track to become
extremely loose and, under some
operating conditions, allow the idler
wheels to climb over the track lugs
forcing the track against the tunnel
causing the track to “lock.” If a track
“locks” during operation, severe per-
sonal injury could result.
