MAINTENANCE

Chaincase Oil

Oil Change 

1. Position the vehicle on a level surface.

2. Remove the drain plug (4) and drain 

the oil into a drain pan. Allow the oil 
to drain completely.

3. Clean off all metal shavings from the 

plug.

4. Install a new sealing washer on the 

drain plug. The sealing surfaces on the drain plug and the oil tank 
should be clean and free of burrs, nicks or scratches.

5. Reinstall the drain plug. Torque to 6-10 ft. lbs. (8-13 Nm).

6. Remove the fill plug. Clean off all metal shavings from the plug.

7. Add 11 oz. (325 ml) of the recommended oil. Do not overfill.

8. Reinstall the fill plug, making sure it is seated properly.

MAINTENANCE

Spark Plugs

A new engine can cause temporary spark plug fouling due to the 
preservative added during the assembly process. Avoid prolonged idle 
speeds, which cause plug fouling and carbonization.

NOTICE: Using non-recommended spark plugs can result in serious engine 

damage. A spark plug with a heat range too high will always cause 
engine damage if the engine is operated in conditions more severe 
than intended for that plug. Always use the spark plugs recommended 
for your snowmobile.

• Use recommended spark plugs with the proper gap. Refer to the 

specifications section beginning on page 120.

• Use only resistor-type spark plugs.

• Torque spark plugs to 18-22 ft. lbs. (24-30 Nm).

Check the spark plug firing end condition after the engine has been 
warmed up and the vehicle has been driven at higher speeds. If a plug is 
fouled, replace the plug with a new plug.

CAUTION! A hot exhaust system and engine can cause burns. Wear 
protective gloves when removing a spark plug for inspection.

Spark Plugs

Normal Spark Plug

The normal insulator tip is gray, tan or light brown. There will be few 
combustion deposits. The electrodes are not burned or eroded. This 
indicates the proper type and heat range for the engine and the service.

Tip: The tip should not be white. A white insulator tip indicates overheating, 

caused by use of an improper spark plug or incorrect carburetor/throttle 
body adjustments.

Wet Fouled Spark Plug

The wet fouled insulator tip is black. A damp oil film covers the firing 
end. There may be a carbon layer over the entire nose. Generally, the 
electrodes are not worn. General causes of fouling are excessive oil or 
use of non-recommended injection oil.

Spark Plug Removal and Replacement

1. Remove the spark plug cap.

2. Using the special wrench provided in the tool pouch, rotate the 

spark plug counter-clockwise to remove.

3. Reverse the procedure for spark plug installation. 

4. Torque to 18-22 ft. lbs. (24-30 Nm).

5. Reinstall the spark plug cap.

MAINTENANCE

Intake Filters

The intake foam filter limits snow 
ingestion into the intake system. 
When operating in loose powder 
snow, check the top of the foam 
filter periodically to remove any 
accumulation of snow.

Fuel Injectors

All fuel injector service must be performed by an authorized POLARIS 
dealer. Do not attempt to clean or service the fuel injectors.

Fuel Pump

All fuel pump service must be performed by an authorized POLARIS 
dealer. Do not attempt to service the fuel pump.

Fuel Filter

See your POLARIS dealer for replacement of the fuel filter at the 
intervals outlined in the Periodic Maintenance Table beginning on page 
85.

Contaminated or poor quality fuel will shorten the life of the fuel filter 
and result in poor engine performance. Always store fuel in clean fuel 
containers. If low fuel pressure or reduced engine performance occurs 
between the recommended fuel filter service intervals, the filter may 
need replacement. See your dealer.

Fuel Lines

Inspect the fuel lines regularly for signs of deterioration or damage. 
Always check fuel line condition after periods of storage. Normal 
deterioration from weather and fuel compounds may occur. Replace 
worn or damaged fuel lines promptly.

NOTICE: Kinking the fuel lines or using a pliers or similar tools to remove fuel 

lines may cause damage to the lines. If a fuel line has been damaged 
or kinked, replace it promptly.
