6. Install the sheave adjuster and cap
screw (w/lock washer and washer)
onto the driven pulley; then
tighten the cap screw until the
movable sheave opens far enough
to allow the belt to be removed.
NOTE: Before installing the drive
belt, use a suitable cleaning sol-
vent to thoroughly clean the
sheaves.
7. Remove the drive belt from the
driven pulley first; then from the
drive clutch.
Installing Drive Belt
1. Place the drive belt (so the part
number can be read) between the
sheaves of the drive clutch first;
then between the sheaves of the
driven pulley.
2. Remove the sheave adjuster and
install it in its original position
(beveled side out); then install the
cap screw, lock washer, washer,
and sheave adjuster back into the
driven pulley. Tighten the cap
screw to 32 ft-lb.
3. Install the belt guard; then close the
left-side access panel.
4. 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 the track drive sprock-
ets. If extremely loose, the idler wheels
may climb over the track lugs forcing
the track against the tunnel causing 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.
! CAUTION
Do not apply Loctite to the driven
pulley cap screw or component
damage may occur.
! WARNING
Never operate the snowmobile
without the belt guard/access
panel secured in place.
! WARNING
Track tension must be properly
maintained. Personal injury could
result if a track is allowed to
become excessively loose.
