How to Change the Chain Case Oil on Your Snowmobile

    November 7, 2016

Good news! The weather is finally getting colder. You know what that means…snow! I recently took my sled out to get it ready for the season and one of the first things I did was change the chain case oil.

This is important for two reasons:

1. Chain case oil breaks down with heating and cooling cycles.

2. Chain case oil can get contaminated by both water and metal slivers from the chain and sprockets.

Simply put, a clean and well-lubed chain means a well-performing sled!

Here’s how to do it:

1. To start, place a drain pan/bucket under the chain case drain plug and remove the plug to drain the oil.

2. Next, remove the chain case cover to expose the gears, chain, and inside of the chain case.

3. Once the cover is off you should inspect the gears and chain for any problems. Check for wear and make sure your chain isn’t too lose. Next, spray LOCTITE® SF 7635™ Pro Strength Degreaser over everything inside the chain case and cover to loosen the oil and metal shavings sludge.

4. Now it’s time to clean. I use LOCTITE® SF 7611™ Pro Strength Parts Cleaner throughout the inside of the chain case to clean and rinse all the gunk out. Start at the top of the chain case and work your way to the bottom to ensure you get everything.

5. Before you move on to the next step everything should be dry. LOCTITE® SF 7611™ Pro Strength Parts Cleaner dries quickly, but I gave it a little extra time by taking Nick on in a little thumb-wrestling battle! (Spoiler alert: he won).

6. Now it’s time to put everything back together. Install both the drain plug and the chain case cover bolts using LOCTITE® 243™ Blue Threadlocker to prevent the bolts from backing out. Using threadlocker will also provide a seal to prevent oil leaks.

7. Once the chain case is back together, fill it with the manufacturer’s suggested amount of oil and check using the dipstick to confirm.

And that’s it! Not too bad, right? It’s easy maintenance that you should do at least once a season. If you ride a lot, you might consider doing it more often. A clean and well-lubed chain is a happy chain!

About the Author, Levi LaVallee

Levi started riding snowmobiles at the young age of eight and from the start, he was hooked and wanted to give racing a try. After placing 2nd in his first snowmobile race, Levi has continued to succeed in racing and worked his way up to the Pro Class in 2003. With the desire to win and the need for speed, after multiple snocross podiums and wins, Levi had the opportunity to try snowmobile freestyle. With the tricks coming naturally, Levi was able to win his first freestyle competition he entered (with only a month of practice) and was awarded an invite to compete in Freestyle, Speed & Style and Snocross in the 2008 Winter X Games (the most disciplines any snowmobile athlete had ever competed in). Since then, Levi has continued to compete in all Snowmobile disciplines in the Winter X Games. He has earned himself a total of 10 Winter X Games medals (7 of which are gold), a snocross Championship Title, the first athlete to attempt a double backflip on a snowmobile and holds the current world record for longest snowmobile distance jump of 412ft (2011 Red Bull: New Year. No Limits. live on ESPN). If being a racer and a freestyle rider wasn’t enough, Levi embarked upon a new opportunity of Team Owner, Team LaVallee in 2009. The future? It is unknown, but one this is certain- Levi has the determination and the desire to continue pushing the limits and elevating the sport of snowmobiling.
