How to Change the Gear and Differential Oil on Your Can-Am ATV or UTV

Why Changing Gear and Differential Oil Matters

Your Can-Am ATV or UTV's gear and differential oil keeps moving parts lubricated and running smoothly. Over time, this oil breaks down and collects dirt and debris. Changing it on schedule helps your vehicle last longer and perform better. Regular maintenance also prevents costly damage to the differential and gearbox, which are expensive to repair.

Check your owner's manual for how often you should change this oil. Most Can-Am models need it done every 500 to 1,000 hours of use, depending on how you ride. If you ride in dusty, muddy, or wet conditions, you may need to change it more often. Keeping up with this maintenance is one of the best things you can do to protect your investment.

What You'll Need

Before you start, gather these items to make the job go smoothly:

• New gear and differential oil (the correct type for your Can-Am model)
• Oil drain pan
• Socket set and wrenches
• Gasket scraper or plastic tool
• New gaskets or seals (if needed)
• Rags or paper towels
• Jack and jack stands (for safety)
• Torque wrench
• Funnel
• Safety glasses

Always check your owner's manual to confirm the exact oil type and capacity for your specific model. Using the wrong oil can harm your vehicle's performance and durability. Different Can-Am models may call for different weights and grades, so don't guess. Having everything ready before you start saves time and prevents mistakes.

Getting Ready

Park your Can-Am on level ground in a well-lit area. Let the engine cool completely if you've been riding. Warm oil drains faster, but hot oil can burn you badly. Give yourself plenty of time for the vehicle to cool down—this is a safety step you shouldn't rush.

Raise the vehicle safely using a jack, then secure it with jack stands under sturdy frame points. Never work under a vehicle held only by a jack. A falling vehicle can cause serious injury or death. Double-check that the vehicle is stable before you slide underneath. Wear safety glasses to protect your eyes from dripping oil and debris.

Draining the Old Oil

Locate the drain plug on your rear differential or gear case. On most Can-Am models, you'll find it on the bottom of the housing. Place the oil drain pan underneath to catch the old oil. Position the pan so it catches the flow—oil can splash, so don't stand directly in line with the drain.

Remove the drain plug by turning it counterclockwise. Let the old oil drain completely—this may take several minutes. While you wait, you can remove the fill plug (usually on top of the housing) to help air in and speed up the draining process. This also prevents a vacuum from forming inside the case.

Once the oil has stopped dripping, wipe the drain plug clean with a rag. Inspect it for damage or wear. If the plug has a crush washer or rubber seal, replace it with a new one. A worn seal can cause leaks later on.

Cleaning the Area

Use a gasket scraper or plastic tool to remove old gasket material from the drain plug hole and fill plug hole. Be gentle so you don't damage the threads or aluminum surfaces. Metal tools can gouge the housing and create weak spots or new leak paths.

Wipe everything clean with a rag to remove dirt and old oil residue. A clean surface helps the new gasket seal properly and prevents contamination of the fresh oil. Take time with this step—it makes a real difference in how well your repair holds up over time.

Reinstalling the Drain Plug

Thread the drain plug back in by hand first to avoid cross-threading. This means turning it slowly and carefully until you feel it catch the threads. Once it's hand-tight, stop and use a wrench or socket to tighten it to the torque specification listed in your owner's manual.

Torque specs matter because they ensure the plug is tight enough to seal but not so tight that it strips the threads or cracks the housing. Most Can-Am drain plugs torque to between 25 and 35 foot-pounds, but check your manual to be sure. Don't overtighten—this is one of the most common mistakes people make.

Adding New Oil

Remove the fill plug completely and set it aside where you won't lose it. Using a funnel, pour in the new gear and differential oil slowly and carefully. Pouring too fast can splash oil and create a mess. Check your manual for the correct amount—overfilling or underfilling both cause problems.

Some Can-Am models have a fill level plug that shows when the oil is at the right height. Others have a sight glass on the side of the housing. Fill until oil reaches the proper level, then replace the fill plug and tighten it to the correct torque setting from your manual. Don't forget this step—a loose fill plug will leak.

Final Steps

Lower your Can-Am back to the ground carefully using the jack. Make sure the vehicle is stable and sitting level before you remove the jack stands. Take your time with this step to avoid accidents.

Start the engine and let it run for a few seconds, then turn it off and wait a minute. This circulates the new oil through the gears. Check the oil level again using the sight glass or fill plug method and top off if needed. It's normal for the level to drop slightly after the first run as the oil settles.

Dispose of old oil at a recycling center or auto parts store—never pour it down a drain or into the ground. Used oil is toxic and harms the environment. Most recycling centers take it for free, and some auto parts stores give you credit toward new oil if you bring in your old oil.

Key Takeaways

• Changing gear and differential oil on schedule keeps your Can-Am running smoothly and prevents expensive damage.
• Always use the correct oil type and weight for your specific model—check your owner's manual.
• Let the engine cool before you start, and always use jack stands for safety.
• Replace drain plug seals and gaskets with new ones to prevent leaks.
• Tighten drain and fill plugs to the torque spec in your manual—not too tight, not too loose.
• Dispose of old oil responsibly at a recycling center or auto parts store.

Frequently Asked Questions

How often should I change the gear and differential oil on my Can-Am?

Most Can-Am ATVs and UTVs need a gear and differential oil change every 500 to 1,000 hours of use. The exact interval depends on your model and riding conditions. Check your owner's manual for the recommended schedule. If you ride in dusty, muddy, or wet conditions regularly, you may need to change it more often than the standard interval.

What happens if I use the wrong oil type?

Using the wrong oil can damage your differential and gears. The wrong viscosity (thickness) won't lubricate properly, leading to wear and overheating. Some oils don't have the right additives for gear protection. Always follow your owner's manual to get the exact oil type, weight, and specification your Can-Am needs. Using the correct oil ensures your vehicle performs as designed and lasts longer.

Can I change the gear and differential oil myself if I've never done it before?

Yes, you can learn to do this job yourself if you follow the steps carefully and have the right tools. Take your time, read your owner's manual thoroughly, and don't skip safety steps like using jack stands. If you're not comfortable working under your vehicle or don't have the tools, a Can-Am dealer or may have access to mechanic can do this job for you. They have the expertise and equipment to do it safely and correctly.

What should I do with the old oil after I drain it?

Never pour old oil down a drain, into the ground, or in the trash. Used oil is toxic and harms the environment. Take it to a recycling center or auto parts store that accepts used oil. Most places take it for free, and some auto parts stores even give you credit toward new oil purchases when you bring in your old oil.
