NOTE: When inserting the tool,
make sure the tool is seated on the
flat portion of the movable sheave
and not on the rib or the cam shoe
boss. The movable sheave may need
to be rotated in order to correctly
align the tool with the flat portion of
the sheave.

3. When the sheaves are apart, pull up
on drive belt and roll belt over sta-
tionary sheave until it is free of the
driven clutch.
4. When the belt is free of driven
clutch, remove the belt from the
drive clutch.
Installing
1. Place the belt (so the arrow is point-
ing toward the front of the snowmo-
bile) between the sheaves of the
drive clutch.
2. With the driven clutch sheaves fully
apart, roll the belt over the stationary
sheave.
3. With the drive belt properly posi-
tioned in the drive clutch and driven
clutch, turn the belt tool counter-
clockwise and roll the belt back and
forth to allow the driven clutch
sheaves to fully close.
4. After the belt is installed properly,
install the left-side access panel.
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 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
(480 km) 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
ZR/LT
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 the midpoint of the track (shock
pad), hook a spring scale around a
track clip; then pull down on the
scale to 20 lb (9 kg). Measure the
deflection (distance) between the
bottom of the wear strip and the
inside surface of the track clip. Mea-
surement should be 2 in. (51 mm).
! 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
contact with a rotating track.
