3. Install the left-side access panel.
! WARNING
Never operate the snowmobile with-
out the belt guard/access panel
secured in place.
4. Release the brake lever lock.
Checking/Adjusting
Deflection (3000)
Drive belt length, condition, and deflec-
tion are all important for peak perfor-
mance.
1. With the engine off, remove the left-
side access panel.
2. Make sure the drive belt is sitting at
the top of the driven clutch sheaves.
3. 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.
4. 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
deflection should be within the
range of 28.5-31.8 mm (1 1/8-1 1/4
in.).

NOTE: Push down on the belt with
the ruler only until the bottom of the
belt flexes upward; then read the
amount of deflection.

NOTE: Turning the set screw
clockwise
between the sheaves (increases belt
deflection
the set
decreases distance between the
sheaves (decreases belt deflection
measurement).
6. 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:
SNO-276A
washers may be done by the snow-
mobile owner if qualified to do so. If
the owner does not feel qualified,
take the snowmobile to an autho-
rized Arctic Cat Snowmobile dealer
for this service. This service is at the
discretion and expense of the snow-
mobile owner.
