Follow this step-by-step snowmobile chaincase oil change guide to get it done right.

Tools and Materials You’ll Need

Before you start your chaincase oil snowmobile service, gather the following:

• XPS chaincase oil
• Drain pan
• 4.5 mm (3/16") Allen key or socket
• Torque wrench
• Flat-head screwdriver
• Funnel
• Clean rag or shop towel
• Gloves and safety glasses

Using XPS chaincase oil ensures your drivetrain is protected in extreme winter conditions. It’s engineered specifically for BRP sleds, so you get the right performance and peace of mind.

Step-by-Step: Snowmobile Chaincase Oil Change

1. Prepare Your Snowmobile

• Park the sled on a flat surface.
• Remove the tether cord for safety.
• Take off the right-side panel to access the snowmobile chaincase.
• Place your drain pan under the belly pan opening where the drain plug is located.

2. Drain the Old Oil

• Use the Allen socket to remove the drain plug.
• Remove the fill cap on top of the chaincase to let air in and speed draining.
• Allow the chaincase oil to drain completely.

3. Reinstall and Torque the Drain Plug

• Clean the plug threads.
• Reinstall the plug by hand to avoid cross-threading.
• Tighten the plug with a torque wrench to the torque specified in your sled’s Operator’s Guide.

4. Refill with Fresh Oil

• Remove the check plug on the side of the snowmobile chaincase.
• Using a funnel, refill with fresh chaincase oil for snowmobile until it begins to drip from the check plug hole.
• If using XPS oil, the amount in the bottle matches the required volume.

5. Close the System and Check for Leaks

• Reinstall the check plug (hand-tight first, then secure).
• Replace the fill cap.
• Wipe down the area and inspect for leaks.

6. Dispose of Used Oil Properly

• Collect the used oil in a sealed container.
• Bring it to a recycling center or authorized Lynx dealer.
• Never dump oil in the environment.

Used oil can contain contaminants. Always handle it with care.

How Often Should You Change Snowmobile Chaincase Oil?

You should perform a snowmobile chaincase oil change every 2 years or 6,000 km (≈ 4,000 miles), whichever comes first. If you ride aggressively or in tough conditions, check your oil every 3,200 km (≈ 2,000 miles).

The best time for a snowmobile chaincase oil service is at the end of the season. This prevents moisture from sitting in the snowmobile chaincase during storage.

What Oil Should I Use for My Lynx Snowmobile?

For best results, always use XPS chaincase oil, recommended by Lynx and engineered specifically for BRP snowmobiles. It’s designed to handle extreme cold, reduce wear, and protect the snowmobile chaincase from moisture and corrosion.

While other oils exist, only XPS chaincase oil for snowmobile is tested and proven in the same demanding conditions your Lynx is built for. It’s the straightforward choice for long-lasting performance.

Check your Lynx Operator’s Guide for the exact chaincase oil capacity of your model.
