Drive Belt Removal

1. Stop the engine after operating in a forward motion.
2. Turn the ignition key off. Wait for the engine to stop completely.
3. Lock the parking brake (if equipped).
4. Open the hood. 
5. Remove the clutch guard retain-

ing pin and open the clutch 

guard.

6. Locate the L-wrench in the tool 

kit and install it into the open 

threaded hole in the outer sheave 

of the clutch. Rotate the wrench 

until the sheaves open far enough 

to remove the belt.

7. Firmly grasp the belt midway 

between the clutches and pull 

upward and rearward to remove. 

See illustration.

CAUTION

Do not attempt to remove the drive belt after operating in reverse. The snow-

mobile must be stopped after forward motion to prevent damage to compo-

nents during belt removal.

Drive Belt Installation

1. Drop the drive belt over the 

drive clutch and pull back 

the slack.

NOTE: To ensure satisfactory 

belt life, install belts so 

they operate in the 

same direction of rota-

tion by positioning the 

identification numbers 

so that you can read 

them. If required, sepa-

rate the sheaves as 

outlined in the belt removal procedures.

2. Turn the driven clutch moveable sheave clockwise while pushing 

inward and forcing the belt down between the sheaves.

3. Hold the belt down between 

the sheaves and roll the bot-

tom portion over the outer 

clutch sheave. Work the belt 

to the outer edge of the 

sheave.

4. Rotate the L-wrench to 

tighten the sheaves. Remove 

the wrench and store in the 

tool kit.

5. Close the clutch guard and 

reinstall the retaining pin.

6. Close and secure the hood and release the parking brake.

Drive Belt Deflection

Measure belt deflection with both 

clutches at rest and in their full 

neutral position.

Place a straight edge (1) on the 

belt and apply downward pressure 

while measuring at point 2. This 

measurement should be 1 1/4 

inches (3.2 cm).

Drive Belt Adjustment

Belt deflection can be adjusted without removing the clutch from the 

jackshaft.

1. Loosen the 7/16-inch jam nut on the belt width adjuster.
2. Using a 1/8-inch Allen wrench, adjust the threaded set screw as 

needed.

NOTE: Turn the set screw in (clockwise) to increase the distance 

between the sheaves and out (counterclockwise) to decrease 

the distance.

3. Tighten the jam nut.

Torque Stop

If your snowmobile is equipped 

with an engine torque stop, periodi-

cally check torque stop clearance.

With clutches in proper alignment, 

the torque stop clearance should be 

.010I-.030I (.25-.75 mm) from the 

engine case.

Adjust if necessary, and lock the 

jam nut.

Reverse Maintenance

If your snowmobile is equipped 

with reverse, or if you have a 

reverse kit installed, it's especially important to maintain track tension 

as specified on page 98.

Allow the engine to reach idle speed before attempting to shift into or 

out of reverse.

WARNING

Improper track tension can cause serious damage to the snowmobile, which 

can result in loss of vehicle control and serious injury or death. Always main-

tain the track tension as specified.

CAUTION

Damage will occur to chaincase or transmission if shifting is attempted before 

the machine has come to a complete stop. Make sure the snowmobile has 

completely stopped and the engine has returned to idle speed before shifting 

gears.
