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 perfor-
mance. Please see your POLARIS dealer if you experience a decrease in 
performance.

MAINTENANCE

Clutch System

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 
141.

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 
inches (3.2 cm).

Drive Belt Adjustment

Belt deflection should 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.

Tip: 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.
