There’s nothing quite like watching a young rider rip around on their Can-Am DS 90. That little machine is a gateway to a lifetime of off-road passion. But keeping that ATV running strong and shifting smoothly depends on maintenance that often gets overlooked: the transmission oil.
You’ve probably got the engine oil changes down to a science, but are you giving the gearbox the attention it deserves? Ignoring it can lead to sticky shifts, gear whine, and eventually, a busted transmission that costs a fortune to fix.
We promise this guide will walk you through every single step of a can-am ds 90 transmission oil change with the confidence of a seasoned pro. We’ll cover the tools you need, the exact steps to take, common mistakes to avoid, and pro tips that will keep that little quad tearing up the trails for years to come.
Why a Regular Can-Am DS 90 Transmission Oil Change is Non-Negotiable
Think of transmission oil as the lifeblood of your ATV’s gearbox. It does more than just lubricate; it cools, cleans, and protects a complex system of moving parts. The benefits of a can-am ds 90 transmission oil change go far beyond just checking a box on your maintenance list.
Protects Gears and Bearings from Premature Wear
Over time, the oil in your transmission breaks down. It gets contaminated with microscopic metal particles from normal gear wear. This gritty, worn-out fluid is a poor lubricant, accelerating wear and tear on crucial internal components.
Fresh oil creates a strong, protective film that prevents metal-on-metal contact, drastically extending the life of your gears and bearings.
Ensures Smooth and Reliable Shifting
Is your young rider having trouble getting the DS 90 into gear? Old, sludgy oil is often the culprit. It can cause the clutch plates (on applicable models) and gears to stick, leading to clunky, difficult, or missed shifts.
Clean oil allows everything to move freely, restoring the crisp, easy shifting the machine had from the factory.
Prevents Overheating and Costly Repairs
Friction creates heat, and worn-out oil can’t dissipate it effectively. An overheating transmission is a failing transmission. The intense heat can warp metal parts and destroy seals, leading to catastrophic failure.
A simple oil change is the cheapest insurance policy you can buy against a four-figure repair bill.
Gearing Up: Tools and Supplies You’ll Need
Before you get your hands dirty, let’s get organized. Having the right tools and supplies on hand makes the job faster, safer, and much less frustrating. This is one of the most important can-am ds 90 transmission oil change best practices.
Essential Tools
- Socket Set & Ratchet: You’ll need the correct size sockets for the fill and drain plugs (typically 13mm or 14mm, but always double-check).
- Torque Wrench: This is highly recommended to avoid over-tightening and stripping the bolts.
- Oil Drain Pan: A low-profile pan works best to catch all the old fluid.
- Funnel: A small, clean funnel is essential for refilling without making a mess.
- Clean Rags or Shop Towels: You’ll need plenty for cleanup.
- Nitrile Gloves: Protect your hands from grime and used oil.
Required Supplies
- Fresh Transmission Oil: The Can-Am DS 90 requires a specific type of gear oil. Do not use engine oil. You need approximately 250 ml (8.5 oz) of SAE 80W-90 API GL-5 gear oil. Always check your owner’s manual to confirm the exact specification.
- New Crush Washers: One for the drain plug and one for the fill plug. These are single-use items and are crucial for preventing leaks. You can get them from your local Can-Am dealer.
How to Can-Am DS 90 Transmission Oil Change: A Step-by-Step Guide
Alright, you’re prepped and ready to go. We’ve broken down this can-am ds 90 transmission oil change guide into simple, actionable steps. Follow them closely, and you’ll be done in no time.
Step 1: Prep and Warm-Up
First, make sure the ATV is on a level surface. Start the engine and let it run for 3-5 minutes. This warms up the transmission oil, making it thinner and allowing it to drain out more completely, taking suspended contaminants with it.
Step 2: Locate the Plugs
On the DS 90, the transmission case is located on the left side of the engine (the shifter side). You’ll find two bolts: the fill/level check plug is higher up, and the drain plug is at the very bottom of the case.
Step 3: Remove the Fill Plug First
Always remove the fill plug before the drain plug. This ensures you can actually refill the transmission after you’ve drained it. If the fill plug is seized, you don’t want to be stuck with an empty gearbox. It also allows air to enter, helping the old oil drain faster.
Step 4: Drain the Old Oil
Position your oil drain pan directly under the drain plug. Using your socket and ratchet, carefully loosen and remove the drain plug. Be prepared for the oil to start flowing as soon as the plug is free.
Step 5: Let It Drain Completely
Let the oil drain for at least 10-15 minutes. To get every last drop out, you can gently and carefully tilt the ATV slightly toward the drain side. Just be sure it’s stable!
Step 6: Inspect the Old Oil and Plug
While it’s draining, look at the old oil. Is it milky (indicating water contamination)? Does it smell burnt? The drain plug is often magnetic; check it for metal shavings. A fine, fuzzy paste is normal, but large metal chunks are a sign of serious internal problems.
Step 7: Clean and Reinstall the Drain Plug
Wipe the drain plug clean, removing all old oil and metal fuzz. Discard the old crush washer and slide a new one onto the plug. Hand-thread the plug back into the transmission case to avoid cross-threading. Use your torque wrench to tighten it to the factory specification (check your manual, but it’s typically around 15 ft-lbs).
Step 8: Refill with Fresh Transmission Oil
Place your clean funnel into the fill hole. Slowly pour in the specified amount of fresh 80W-90 gear oil. The DS 90 takes about 250 ml (8.5 oz). Don’t just dump it all in; pour slowly to prevent air pockets.
Step 9: Check the Oil Level
The fill hole also doubles as the level check. The correct oil level is right at the bottom edge of the fill hole threads. With the ATV perfectly level, the oil should be just about to seep out. If you can’t see it, you can use a zip tie as a makeshift dipstick to check the level.
Step 10: Final Checks and Clean Up
Once the level is correct, wipe the fill plug clean, install its new crush washer, and tighten it securely. Wipe down any drips on the transmission case. Now, you’re ready to tackle the important task of proper disposal.
Common Problems with Can-Am DS 90 Transmission Oil Change (And How to Avoid Them)
Even a simple job can go wrong. Being aware of these common pitfalls will save you a massive headache. Here are some of the most frequent common problems with can-am ds 90 transmission oil change we see.
Stripping the Drain or Fill Plug
The transmission case is typically made of aluminum, which is softer than the steel bolts. Using the wrong size socket, a worn-out tool, or over-tightening can easily strip the threads.
Solution: Always use a snug-fitting, 6-point socket and a torque wrench set to the manufacturer’s specification. If it feels too tight, stop.
Overfilling or Underfilling
Too much oil can cause seals to blow out due to excess pressure, while too little oil will lead to overheating and lubrication starvation. Both are bad news.
Solution: Measure the fluid carefully and always check the level at the fill hole with the ATV on level ground. Don’t guess.
Using the Wrong Type of Oil
This is a critical mistake. Engine oil contains friction modifiers that are not compatible with the clutch systems and gear types in a separate transmission. Using it can cause slippage and rapid wear.
Solution: Double-check your owner’s manual and buy the exact oil it specifies: SAE 80W-90 API GL-5 Gear Oil.
Sustainable and Eco-Friendly Can-Am DS 90 Transmission Oil Change
Part of being a responsible off-roader is protecting the trails and environment we love to ride in. An eco-friendly can-am ds 90 transmission oil change is easy to do and makes a big difference.
Proper Disposal of Used Oil
Used gear oil is a hazardous material. Never pour it down the drain, on the ground, or in the trash. A single oil change can contaminate millions of gallons of water.
Pour the old oil from your drain pan into a sealed container (like the empty oil bottle). Most auto parts stores (like AutoZone, O’Reilly) and local recycling centers will accept used oil for free.
Minimizing Spills and Waste
Use a large drain pan to prevent spills. If a spill does happen, clean it up immediately with an absorbent material like kitty litter or a dedicated oil absorbent, rather than hosing it away. This is a core part of a sustainable can-am ds 90 transmission oil change.
Frequently Asked Questions About the Can-Am DS 90 Transmission Oil Change
What is the Can-Am DS 90 transmission oil capacity?
The transmission oil capacity for the Can-Am DS 90 is approximately 250 ml or 8.5 fluid ounces. Always confirm with your owner’s manual, but this is the standard volume.
