WARNING
Do not modify track, including the
installation of traction enhancing
products. At speed it may cause
the track to tear and separate from
vehicle posing a risk of severe in-
jury or death. Do not operate or
rotate a track if torn, damaged or
excessively worn (fibers showing).
Track Adjustments
NOTE: Track tension and alignment
are inter-related. Do not adjust one
without the other.

WARNING
– Never stand behind or near a ro-
tating track.
– Never spin the track at high
speed whenever off the ground.
Broken track or debris could be
projected with great force which
could severe legs or cause other
serious injuries.
Tension
NOTE: Ride the snowmobile in snow
about 15 to 20 minutes prior to adjust-
ing track tension.
Remove the tether cord cap (DESS
key).
Lift rear of snowmobile and support
it with a wide-base snowmobile me-
chanical stand equipped with a protec-
tor back panel.
Allow the suspension to extend nor-
mally and check gap half-way between
front and rear idler wheels. Measure
between slider shoe bottom and in-
side of track. The gap should be as
given in the
SPECIFICATIONS section.
If the track tension is too loose, track
will have a tendency to thump.
NOTE: A belt tension tester (P/N 414
348 200) may be used to measure de-
flection as well as force applied.
