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 
following procedure:

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

container 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 snowmobile 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 
cylinder 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 to 5 on remaining 

cylinders.

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

Controls and Linkage

All bushings, spindle shafts, tie rod ends, and cables should receive a 
light coat of oil or grease.

Bearings

Grease the drive shaft clutch side bearing with POLARIS Premium All-
Season Grease or a similar high quality grease to prevent corrosion. See 
page 106 for part numbers.

Clutch and Drive System

Remove the drive belt and store in a cool dry location. Lubricate the 
sheave faces of the drive and driven clutches with a light coat of oil or 
POLARIS Cable Lubricant. See page 106 for the part numbers of 
POLARIS products. Do not lubricate clutch components, except the 
driven clutch shaft bushing as outlined in the Master Repair Manual. 
See your dealer.

MAINTENANCE

Extended Storage

Electrical Connections

Separate electrical connector blocks and clean corrosive build-up from 
connectors. Lubricate or pack connector blocks with dielectric grease 
and re-connect. See page 106 for the part numbers of POLARIS 
products.

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 96.

Track and Suspension

Moderate track tension should be maintained during summer storage. 
The snowmobile 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.

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.
