MAINTENANCE

Clutch System

Drive Belt Installation

1. Drop the drive belt over the 

drive clutch and pull back 

the slack.

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. 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.

Clutch System

Drive Belt Deflection

Measure belt deflection with 

both clutches at rest and in 

their full neutral position.
Place a straight edge on the 

belt (1) and apply downward 

pressure while measuring at 

point 2. This measurement 

should be 1 1/4 inches (32 

mm).

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.

Clutch System

Torque Stop

Periodically check torque stop 

clearance. With clutches in 

proper alignment, the torque stop 

clearance should be .010-.030 

inch (.25-.75 mm) from the 

engine case.
Adjust if necessary, and lock the 

jam nut.

Tool Kit

A tool kit is included with each 

machine for emergency and rou-

tine maintenance. Always keep 

the tool kit with the snowmobile.

Chain Tension

Maintain the proper chain tension as outlined on page 80.

Fall Tune-Up

For maximum performance, arrange for a fall service tune-up with your 

Polaris dealer.

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 support the rear of the 

snowmobile off the ground.

2. Rotate the track by hand to 

check for possible 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 

damage is found.
