64 MAINTENANCE
2. Using the deflection tool/screw-
d r i v e r / s p a r k p l u g w r e n c h
assembly, remove the sheave
adjuster from the end of the
driven pulley.
3. Place the shim washers and O-
ring (as noted in removing)
onto the sheave adjuster; then
carefully thread the sheave
adjuster back into the driven
pulley. Tighten the adjuster
securely using the deflection
tool/screwdriver/spark plug
wrench assembly.

NOTE: Do not over-tighten the
sheave adjuster. A torque value of
2 . 1 k g - m ( 1 5 f t - l b ) i s r e c o m -
mended.
4. Close the belt guard; then
install the driven pulley plug.
5. Release the brake lever lock.
TRACK TENSION
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
t h e t r a c k d r i v e s p r o c k e t s . I f
extremely loose, the idler wheels
may climb over the track lugs forc-
ing the track against the tunnel caus-
ing the track to “lock.” Arctic Cat
recommends that the track tension
be checked daily during the first 300
miles of operation and once a week
thereafter and adjusted according to
need. The track will stretch and take
a “set” during break-in. Track
deflection must be maintained
within the recommended range.
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 snowmobile up on a
shielded safety stand. Check to
make sure the track is 5-8 cm
(2-3 in.) off the floor.
3. At mid-point of the track (on
the bottom side), hook a spring
scale around a track clip; then
pull down on the scale to the
recommended pressure. Mea-
sure the deflection (distance)
between the bottom of the wear
strip and the inside surface of
the track clip. Compare the
measurement with the chart.

NOTE: On King Cat models and
M-Series models, no pressure
should be applied to the track.
! WARNING
Never operate the snowmobile
without the belt guard secured
in place.
! WARNING
Track tension must be properly
maintained. Personal injur y
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.
