TRACK TENSION
„
NOTE: Track tension and track
alignment are interrelated; there-
fore, always check both, even if
only one adjustment seems nec-
essary.
Track tension is directly related to the
overall performance of the snowmobile.
If the track is too loose, it may slap
against the tunnel causing wear, or it
may ratchet on the track drive sprock-
ets. Arctic Cat recommends that the
track tension be checked once a month
and adjusted accordingly.
Checking Track
Tension
1. Remove excess ice and snow
buildup from the track, track drive
sprockets, and the inside of the skid
frame.
2. Place the rear of the snowmobile
up on a safety stand high enough so
the track is free of the floor.
3. Without exerting any pressure on
the track, measure the distance
between the bottom of the wear
strip and the inside surface of the
track. The measurement must be
within specifications of 6.4-9.5 mm
(1/4-3/8 in.). If the measurement is
not within specifications, an adjust-
ment is necessary.

ing bolt jam nuts.

NOTE: To ensure proper track
tension adjustment, perform all
adjustments on both sides of the
snowmobile.
! WARNING
Track tension must be properly
maintained. Personal injury could
result if a track is allowed to
become excessively loose.
! WARNING
DO NOT attempt to check or
adjust track tension with engine
running. Turn ignition key to the
OFF position. Personal injury
could result from contact with a
rotating track.
