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 or qualified person immediately. Do not operate the snowmobile until repairs have been made.
All clutch maintenance and repairs can 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. Your dealer can perform service and adjustments. A special tool is required to check for proper alignment.

Drive Belt Condition

Periodically check the condition and tension of the drive belt. 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.
Always carry a spare drive belt. When placing the belt in the holder, orientate the belt to match the profile of the hood.
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. This measurement should be 1 1/4 inches (3.2 cm).

Drive Belt Adjustment

  1. Loosen the 7/16-inch jam nut on the belt width adjuster.
  2. Using a 1/8-inch Allen wrench, turn the set screw inward (clockwise) to increase the distance between the sheaves or outward (counter-clockwise) to decrease the distance.
  3. Tighten the jam nut.

Drive Belt Removal

IMPORTANT
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. Rotate the driven clutch counter-clockwise 1/4 turn by hand to ensure forward engagement.
  4. Lock the parking brake.
  5. Remove the left side panel.
  6. Retrieve the L-wrench . 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.

  8. Firmly grasp the belt midway between the clutches and pull upward and rearward to remove it from the driven and then drive clutch.

Drive Belt Installation

  1. With the L-wrench inserted into the threaded hole and the sheaves in the open position, install the drive belt.
    TIP

    Install the belt so that the numbers can be read correctly on the left side of the vehicle, or in the direction in which the belt was originally installed.

  2. Wiggle the belt to remove slack while removing the L-wrench.
  3. Reinstall the side panel.
  4. Break in the new belt. See Drive Belt Break-In.
