This video will outline the pump and front cover methods that can be used to change the chaincase fluid on a Polaris INDY XC. Always wear safety glasses and nitrile gloves when servicing your snowmobile.
To replace the chaincase fluid on your snowmobile, follow these steps:
1. Ensure the vehicle is on a flat, level surface.
2. Set the parking brake.
3. Clean the area around the fill plug. Tip: Place a rag under the fill plug to catch any escaping fluid.
4. Using a 6mm Allen socket, remove the fill plug and set it aside.
5. To extract the fluid using the pump method:
- Safely elevate the front of the vehicle using a floor jack or appropriate lift.
- Insert the tube of the suction device into the fill hole. Direct the hose toward the bottom front area of the cover, away from the chain and sprocket.
- Extract the oil from the chaincase.
- Safely lower the snowmobile.
6. To drain the fluid using the front cover method:
- Remove the right side panel by releasing the rubber strap and turning the two quarter-turn latches. Pull the panel out and remove.
- Remove the three push rivets securing the side panel trim. Pull the trim apart as needed.
- If equipped with a battery, remove the battery and bracket.
- Remove the two T40 TORX® fasteners securing the lower fender to the chaincase.
- Place a drain pan underneath the chaincase. Tip: Place a rag in the bottom of the drain pan to prevent the splashing of fluid.
- Using a 10mm socket, loosen but do not remove the three lower chaincase cover screws.
- Carefully pry the cover open on the cover tab. Caution: DO NOT insert a screwdriver or pry bar between the cover and chaincase. Seal damage may occur.
- Allow the fluid to drain completely.
- Reinstall the three cover fasteners. Torque to 11 ft-lbs (15 Nm).
7. Fill the chaincase through the fill plug hole until fluid reaches the bottom threads and begins to spill out. The required fluid is Polaris Synthetic Snowmobile Chaincase Lubricant, part number 2873105.
8. Reinstall the fill plug. Torque to 4 ft-lbs (6 Nm).
9. Clean any residual fluid off the vehicle and dispose of the used fluid properly.
10. If using the front cover method, continue with the following steps:
- Reinstall the fasteners securing the lower fender to the chaincase. Torque to 36 in-lbs (4 Nm)
- If needed, reinstall the battery and bracket. Ensure the harness is properly routed inside the bracket.
- Reconnect the side panel trims and reinstall the three push rivets.
- Then reinstall the side panel by inserting the tabs on the front and bottom. Secure the rubber strap and quarter-turn latches.
