Snowmobile Seasonal Maintenance: Preparing Your Snowmobile for Winter Riding

7 Steps to Summerize Your Snowmobile

As that beautiful sugary white stuff melts into a sad pile of brown crud, we riders accept that it's time to put our snowmobiles into temporary retirement for the summer.

Whether you stow your sled in the garage, outdoors, or in a storage unit, now is the time to perform a few crucial maintenance steps.

1. Prep Your Storage Space

You'll need the right gear to protect your sled while it's in storage. To begin with, covers will minimize moisture and keep the elements at bay. This may also be the best time to look at trailering gear to simplify transporting your snowmobile into and out of storage.

 

Finally, you'll need a way to get your sled off the ground to avoid track corrosion and minimize shock tnesion. Chekc out Polaris Dolly products, which make moving your snowmobile a breeze.

2. Add Fuel Stabilizer & Fog the Engine

Ethanol fuel attracts moisture which can cause corrosion. Even fuel without ethanol can cause problems. Bottom line? If you let your gas tank sit all summer long filled with ethanol fuel and no stabilizer, you'll damage your engine. Pick up some Carbon Clean fuel stabilizer to prevent corrosion and keep your motor clean in the off-season. In addition, you'll want to fog your engine, which requires accessing your carbs or throttle bodies.

3. Remove & Store Your Battery

Removing your battery to keep it at a full charge and away from potentially corrosive debris can extend its life significantly. Choose a cool, dry location with an outlet nearby so you can attach your battery to a BatteryMINDer®, or another battery charger.

4. Remove Your Drive Belt

Your driven clutch belt works hard all winter long. You'll want to remove your belt both to inspect it and to relieve tension, which can help keep it working hard next winter too. Store your drive belt in a cool, dry location your won't forget about.

5. Inspect & Loosen Your Track

Tension on your snowmobile track and regular riding will wear it down over time. As you know, a new track ain't cheap. You'll want to inspect your track for wear at the end of the season, and reduce the tension to give it much needed rest for a few months.

6. Fix Broken Parts & Upgrade Accessories

When the snow flies again, nothing would be worse than not being able to hop on your sled due to a busted part. Get ahead of your next season by tuning up your sled, or adding an accessory you've had your eye on. There's no better time for maintenance than when your snowmobile is already propped up and out of use for the few months.

7. Clean & Lubricate Your Snowmobile

Moisture, salt, dirt and other debris can all find a way to corrode your snowmobile's most essential parts. While buffing up your sled looks cool, it's also a crucial step to ensure your machine's longevity. Every casing, bearing, chain and part deserves a solid clean and lubrication. Pick up some all-purpose cleaner, all-season grease, chaincase lubricant and go to town.

8. Top Off Engine Oil & Adjust Lubricants

What’s out of sight is often out of mind. Which means even the most experienced riders forget to top off their engine oil once in a while. Refer to your snowmobile owner’s manual and fill to the appropriate level. 

Depending on your storage situation, a snowmobile can accumulate dust, debris and moisture during the off-season. Clean and check all fittings, pivots and cables to ensure they are properly lubricated. Add and adjust lubricants as needed on rear suspension, front suspension, steering components, as well as your chaincase.
