MAINTENANCE

Clutch System

Periodically inspect clutch sheaves for damage, wear or belt residue. To 
maintain optimum performance, clean with non-oil based cleaners such 
as isopropyl alcohol.

WARNING! If you become aware of higher than normal clutch engagement or 
an unusual vibration or shift pattern, see your dealer immediately. Do not 
operate the snowmobile until repairs have been made. 

WARNING! All clutch maintenance and repairs must be performed by an 
authorized POLARIS dealer. Any unauthorized modifications to clutches, such 
as adding or removing weights, will void the warranty.

NOTICE: The bushings in the weights and rollers of POLARIS clutches are 

made of a material that may be damaged if lubricated. Do not 
lubricate clutch bushings.

Clutch Alignment Offset

Clutch alignment offset is important for maintaining optimum 
performance. Please see your POLARIS dealer if you experience a 
decrease in performance.

Drive Belt Condition

Periodically check the condition and tension of the drive belt, and 
always carry a spare. Inspect the belt for signs of excessive wear: frayed 
edges, missing cogs, cracks and excessive looseness. Replace the belt if 
any of these conditions exist. See Drive Belt Troubleshooting on page 
121.

For improved drive-away during extremely cold temperatures, remove 
the belt and warm it to room temperature. Reinstall it before starting the 
snowmobile. 

Drive Belt Deflection

Measure belt deflection with both 
clutches at rest and in their full 
neutral position.

Place a straight edge on the belt 
and apply downward pressure 
while measuring at point A. This 
measurement should be 1 1/4” 
(3.2 cm).

Drive Belt Adjustment

1. Install the L-wrench into the open threaded hole in the outer sheave 

of the clutch (see page 98). Turn the wrench clockwise slightly to 
remove pressure from the sheaves.

2. Loosen the 7/16-inch jam nut.

3. Using a 1/8-inch Allen wrench, aturn the set screw inward 

(clockwise) to increase the distance between the sheaves or outward 
(counterclockwise) to decrease the distance.

4. Tighten the jam nut. Remove the L-wrench and store it in the tool 

kit.

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 
counterclockwise 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. Open the hood and remove the left side panel.

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

ensure forward engagement.

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

threaded hole in the outer sheave of the clutch.

7. 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.

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