Drive Belt Removal 

NOTICE: Do not attempt to remove the drive belt after operating in reverse. The 

snowmobile must be stopped after forward motion to prevent damage 

to components during belt removal. Rotate the driven clutch counter-

clockwise 1/4 turn by hand to ensure forward engagement before 

attempting to remove the belt.

1. Stop the engine after operating in a forward motion.
2. Turn the ignition key off. Wait for the engine to come to a complete 

stop.

3. Lock the parking brake.
4. Remove the left side panel.
5. Remove the clutch guard retaining pin and open the clutch guard.
6. Rotate the driven clutch counter-clockwise 1/4 turn by hand to 

ensure forward engagement.

7. Locate the L-wrench in the tool kit. Install the wrench into the open 

threaded hole in the outer sheave of the clutch.

8. Turn the wrench clockwise until the sheaves open far enough to 

remove the belt. If the wrench does not turn readily, rotate the 

driven clutch counter-clockwise an additional 1/4 turn by hand and 

try again.

9. Firmly grasp the belt midway between the clutches and pull upward 

and rearward to remove it.

Drive Belt Installation

1. Drop the drive belt over the 

drive clutch and pull back the 

slack.

2. To ensure satisfactory belt 

life, install belts so they oper-

ate in the same direction of 

rotation by positioning the 

identification numbers so that 

you can read them. If 

required, separate the sheaves 

as outlined in the belt 

removal procedures.

3. Turn the driven clutch moveable sheave clockwise while pushing 

inward and forcing the belt down between the sheaves.

4. Hold the belt down between the sheaves and roll the bottom portion 

over the outer clutch sheave. Work the belt to the outer edge of the 

sheave.

5. Rotate the L-wrench to tighten the sheaves. Remove the wrench and 

store in the tool kit.

6. Close the clutch guard and reinstall the retaining pin.
7. Reinstall the side panel.

Track Maintenance

Track Inspection

WARNING! Broken track rods can cause a rotating track to come off the 

snowmobile, which could cause serious injury or death. Never operate with a 

damaged track. Never rotate a damaged track under power. 

1. Using a hoist, safely lift and 

support the rear of the snow-

mobile off the ground.

2. Rotate the track by hand to 

check for damage.

3. Carefully examine the track 

along the entire length of each 

rod (+). Bend the track to 

check for breakage. 

4. Replace the track if any rod 

damage is found.

Track Lubrication

The slide rail needs snow for lubrication. Excessive wear indicates 

insufficient lubrication. A new rail slide can cause faster heat build-up 

in limited lubrication, resulting in excessive wear. 

WARNING! Operating with insufficient lubrication between the rail slide and 

track guide clips can cause track failure, loss of vehicle control and loss of 

braking ability, which can result in serious injury or death. Avoid operating for 

extended periods on ice and other surfaces that have little or no snow for 

lubrication.

If excessive rail slide wear occurs due to poor snow conditions, addi-

tional wheel kits are available. See your dealer for more information.
Track damage or failure caused by operation on ice or under other poor 

lubrication conditions will void the track warranty.

Track Maintenance

WARNING! Moving parts can cut and crush body parts. When performing the 

checks and adjustments recommended on the following pages, stay clear of all 

moving parts. Never perform track measurement or adjustments with the engine 

running.

Track Tension

Track adjustment is critical for proper handling. Always maintain cor-

rect tension and alignment.

TIP: Tension adjustments should be made only after the track is warmed up and 

limber.

1. Turn the engine off.
2. Lift the rear of the snowmobile and safely support it off the ground.
3. Place the recommended weight or downward pressure on the track 

at the specified distance (see chart) ahead of the center of the rear 

idler wheel.

4. Measure at the point where the weight is hanging.
