1. Place a straightedge on the top of the
drive belt. The straightedge should
reach from the drive clutch to the top
of the driven clutch.
NOTE: Make sure the drive belt is
all the way out in the driven clutch
before checking drive belt deflection.
2. Using a stiff ruler centered between
the drive clutch and driven clutch,
push down on the drive belt just
enough to remove all slack and note
the amount of deflection. The deflec-
tion should be within the range of
28.5-31.8 mm (1 1/8-1 1/4 in.).
3. To correct drive belt deflection,
remove the sheave adjuster from the
clutch, remove or add shim washers
to the adjuster, and install the adjuster.
NOTE: Adding shim washers will
decrease belt deflection and remov-
ing shim washers will increase belt
deflection. Available shim washers
from Arctic Cat are p/n 0648-714
(0.090 in.) - one included in the tool
kit, p/n 0648-715 (0.030 in.), and p/n
0648-716 (0.060 in.).
NOTE: Removing/adding shim wash-
ers may be done by the snowmobile
owner if qualified to do so. If the owner
does not feel qualified, take the snow-
mobile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
Removing Drive Belt

Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.

reverse the sheave adjuster.
0744-551
6. Install the sheave adjuster and cap
screw into the driven clutch; then
tighten the cap screw until the mov-
able sheave opens far enough to
allow the belt to be removed.
7. Remove the drive belt from the driven
clutch first; then from the drive clutch.
NOTE: Before installing the drive
belt, use a suitable cleaning solvent
to thoroughly clean the sheaves.
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 and the arrows are
facing the front of the snowmobile)
between the sheaves of the drive
clutch
first;
then
between
the
sheaves of the driven clutch.
