6. Install the sheave adjuster and cap
screw onto the driven pulley; then
tighten the cap screw until the mov-
able sheave opens far enough to
allow the belt to be removed.
NOTE: Before installing the drive
belt, use a suitable cleaning solvent
to thoroughly clean the sheaves.
7. Remove the drive belt from the
driven pulley first; then from the
drive clutch.
Installing Drive Belt
NOTE: If a new drive belt is being
installed, see Drive Belt Break-In
sub-section in the General Infor-
mation section.
1. Place the drive belt (so the part num-
ber 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 sprockets. If extremely
loose, the idler wheels may climb over the
track lugs forcing the track against the tun-
nel 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.
Checking Track Tension
1. Remove excess ice and snow buildup
from the track, track drive sprockets,
and the inside of the skid frame.
2. Elevate the snowmobile on a
shielded safety stand high enough to
use a spring scale.
3. At mid-point of the track (on the bot-
tom side), hook a spring scale around a
track clip; then pull down on the scale
to the recommended pressure. Measure
the deflection (distance) between the
bottom of the wear strip and the inside
surface of the track clip. Compare the
measurement with the chart.
CAUTION
Do not apply Loctite to the driven pul-
ley cap screw or component damage
may occur.
! WARNING
Never operate the snowmobile with-
out the belt guard/access panel
secured in place.
! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively 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 con-
tact with a rotating track.
