MAINTENANCE

Extended Storage

Bearings

Grease the drive shaft clutch side bearing with Polaris Premium All-

Season Grease or a similar high quality grease to prevent corrosion.

Clutch and Drive System

Remove the drive belt and store in a cool dry location. To prevent oxida-

tion on the clutch sheaves, lubricate the sheave faces of the drive and 

driven clutches with a light coat of oil or Polaris Cable Lubricant. 

NOTE: After storage, always use acetone or alcohol to remove the oil 

before reinstalling the drive belt. 

Do not lubricate other clutch components, except the driven clutch shaft 

bushing as outlined in the Master Repair Manual. See your dealer.

Engine and Carburetor Protection

Proper preparation of the engine and fuel system is vital to the preven-

tion of rust and corrosion on precision engine parts during storage. 

Whenever the machine is stored for a period of more than 60 days, the 

engine must be fogged with fogging oil. Follow the engine fogging 

instructions provided on the container.

Always add Premium Carbon Clean or a fuel conditioner/stabilizer to 

the fuel tank. Follow the instructions on the container, running the 

engine for five minutes to get additives through the entire fuel system. 

Top off with fresh fuel.

If stabilizer is not used, drain the carburetors by removing the water trap 

drain plugs. See page 84. 

NOTE: Jet restriction caused by improper storage can cause lean con-

ditions and very poor slow speed driving quality.

Engine and Carburetor Protection

Using a fuel stabilizer and topping off the fuel tank eliminates the need 

to drain the fuel system. If you prefer to drain the fuel tank, use the fol-

lowing procedure

1. Transfer unused fuel from the fuel tank to an approved fuel con-

tainer using a siphon pump. Do not re-use fuel after storage.

2. Securely support the front of the snowmobile with a jack stand so 

the machine is elevated and the engine is tilted rearward. 

3. Remove the spark plug(s).
4. Rotate the engine slowly, watching the piston until it's at bottom 

dead center (BDC), the lowest position in the cylinder. On twin cyl-

inder models, the opposite piston will be up.

5. Pour approximately two ounces of Polaris injector oil into the spark 

plug hole.

6. Wait one to two minutes and perform steps 3-5 on remaining cylin-

ders.

7. Replace the spark plugs and lower the machine to the floor.

Electrical Connections

Separate electrical connector blocks and clean corrosive build-up from 

connectors. Lubricate or pack connector blocks with dielectric grease 

and re-connect. 

Replace worn or frayed electrical wire and connectors. Be sure wiring 

harness is properly secured away from sharp edges, steering linkage, 

moving parts, and hot exhaust parts.

Battery

Always prepare and maintain the battery as outlined on page 107.

Track and Suspension

Moderate track tension should be maintained 

during summer storage. The machine should be 

supported off the ground to allow the track to 

hang freely.

Transporting the Snowmobile

Whenever the snowmobile is transported:

1. Turn the fuel valve off. See page 57.
2. Be sure the fuel cap and oil cap are installed correctly.
3. Always tie the snowmobile to the transporting unit securely using 

suitable straps.

4. Remove the ignition key to prevent loss.
