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.

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. Open the hood.

5. Remove the left side panel.

6. Rotate the driven clutch counterclockwise 1/4 turn by hand to 

ensure forward engagement before attempting to remove the belt.

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 counterclockwise an additional 1/4 turn by hand and 
try again.

9. Grasp the belt at the lower edge and remove it.

Clutch System

Drive Belt Installation

1. Drop the drive belt over the drive 

clutch and pull back the slack. The 
belt cord line should be flush with, 
or slightly above, the outer circum-
ference of the driven clutch sheaves. 
The belt will seat itself in the driven 
clutch during the break-in period. 
Adjust the belt ride-out after the 
break-in period by readjusting belt 
deflection.

Tip: To ensure satisfactory belt life, install belts so they operate 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.

2. Rotate the L-wrench counter-clockwise to tighten the sheaves while 

working the belt to the outer edge of the sheaves.

3. Remove the wrench.

4. Reinstall the side panel.

5. Close and secure the hood.

6. Break in the new belt. See page 66.

MAINTENANCE

Track Replacement

When replacing the track, always install a track having the lug size rec-
ommended for your model. See your POLARIS dealer.

NOTICE: Installing tracks with larger lugs on machines equipped with coolers 

will result in damage to the cooler or tunnel. Always install a track 
having the lug size recommended for your model.

Track Inspection

WARNING! Broken track rods can cause a rotating track to come off the 
machine, 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 sup-

port the rear of the snowmobile 
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 break-
age. 

4. Replace the track if any rod dam-

age is found.

MAINTENANCE

Track Lubrication

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.

The slide rail requires adequate snow cover for sufficient lubrication. 
Excessive wear indicates insufficient lubrication. A new rail slide can 
cause faster heat build-up in limited lubrication, resulting in excessive 
wear.

Track damage or failure caused by operation on ice or under other poor 
lubrication conditions will void the track warranty.

NOTICE: High speed use on hard-packed surfaces is not recommended for 

models equipped with a deep lug track. Track lug damage may occur. 
Keep high speed use to a minimum, including frequent slow-speed 
intervals for track cooling.
