Why Your DS 70’s Gearbox Oil is a Non-Negotiable Priority
It’s easy to focus on engine oil and forget about the gearbox, but this fluid is the lifeblood of your ATV’s transmission. It’s a small system, but it works hard every time your young rider hits the throttle.
The gearbox oil has three primary jobs: it lubricates the moving gears to prevent metal-on-metal grinding, it helps dissipate heat generated by friction, and it carries away tiny metal particles that flake off during normal operation. Ignoring it is a surefire way to end up with a costly repair bill and a disappointed rider.
The Real Benefits of Can-Am DS 70 Gearbox Oil Maintenance
Sticking to a regular service schedule isn’t just about preventing disaster. This simple task is one of the best things you can do for your machine’s health. Here are the core benefits:
- Extended Transmission Life: Fresh oil provides maximum protection against wear and tear, ensuring the gears and bearings last as long as they were designed to.
- Smoother Operation: Clean, proper-viscosity oil allows the gears to engage smoothly, which can be felt in the overall performance and responsiveness of the ATV.
- Early Problem Detection: Inspecting the old oil when you drain it is like a health check-up. You can spot signs of water contamination or excessive metal wear before they become catastrophic failures.
- Peace of Mind: Knowing you’ve properly maintained a critical component means you can let your rider explore with confidence. This is a key part of our can am ds 70 gearbox oil care guide.
Choosing the Right Can-Am DS 70 Gearbox Oil
Walking into an auto parts store can be overwhelming with all the options on the shelf. The good news is that the DS 70 keeps it simple. The most important rule is to always consult your owner’s manual first. It is the ultimate source of truth for your specific model year.
Generally, these youth ATVs call for a standard SAE 80W-90 API GL-5 Hypoid Gear Oil. This is a very common type of gear lubricant designed for the high-pressure environment inside a gearbox.
Synthetic vs. Conventional: What’s Best?
You’ll see both conventional (mineral-based) and synthetic versions of 80W-90 oil. For a small, air-cooled machine like the DS 70, a high-quality conventional gear oil is perfectly adequate and cost-effective.
Synthetic oil offers superior performance in extreme temperatures and can last longer, but given the small oil capacity and recommended change intervals for the DS 70, you’ll likely get the most value from simply using a quality conventional oil and changing it regularly.
A Note on Eco-Friendly Can-Am DS 70 Gearbox Oil
For those looking for more sustainable options, some brands offer biodegradable or eco-friendly can am ds 70 gearbox oil. These are formulated to break down more readily in the environment if spilled.
However, the most important aspect of being eco-friendly is proper disposal. Never pour used oil on the ground or down a drain. Always collect it in a sealed container and take it to your local auto parts store or municipal recycling center. Most places accept used oil for free.
How to Change Your Can-Am DS 70 Gearbox Oil: A Step-by-Step Guide
Alright, this is where the real work begins. This is a straightforward job that any DIYer can handle with basic tools and a little patience. Following this how to can am ds 70 gearbox oil guide will ensure you do it right.
Tools and Supplies You’ll Need
Gather everything before you start to make the process smooth. There’s nothing worse than having a drained ATV and realizing you’re missing something.
- Ratchet and socket set (check your manual for exact sizes for drain/fill plugs)
- Oil drain pan
- Funnel with a flexible neck
- Shop rags or paper towels
- Nitrile gloves
- The correct type and amount of new 80W-90 gear oil (the DS 70 takes very little, around 75-100ml)
- New crush washers for the drain and fill plugs (highly recommended)
The Step-by-Step Process
Follow these steps carefully for a mess-free and successful oil change.
- Warm It Up: Run the ATV for 2-3 minutes. Just enough to warm the oil slightly, which helps it drain faster and more completely. Don’t get it scorching hot.
- Locate the Plugs: On the rear of the transmission case, you’ll find a fill plug (usually higher up) and a drain plug (at the lowest point). Clean the area around both plugs thoroughly with a rag to prevent dirt from falling into the gearbox.
- Position the Pan: Slide your oil drain pan directly underneath the drain plug.
- Pro Tip – Remove the Fill Plug FIRST: Always loosen and remove the fill plug before the drain plug. This ensures you can actually refill the gearbox once it’s empty. If the fill plug is seized, you’re not stuck with an immobile ATV.
- Drain the Old Oil: Place your socket on the drain plug and remove it. Let the old oil drain completely into the pan. This may take a few minutes.
- Inspect the Plug and Oil: The drain plug is often magnetic. Check it for metal shavings. A fine, fuzzy paste is normal wear. Large chunks or slivers could indicate a bigger problem. Also, look at the old oil. If it looks milky or creamy, you have water contamination.
- Reinstall the Drain Plug: Wipe the drain plug clean. Slide a new crush washer onto it. Hand-tighten the plug, then give it a final snug turn with your ratchet. Do not overtighten!
- Refill with New Oil: Insert your funnel into the fill plug hole. Slowly pour in the specified amount of new 80W-90 gear oil. The owner’s manual will give the exact capacity (e.g., 75 ml or 2.5 oz). The oil level should be right at the bottom of the fill plug hole threads.
- Reinstall the Fill Plug: Once filled, wipe the fill plug, install its new crush washer, and tighten it securely. Again, snug is enough.
- Clean Up: Wipe away any spilled oil from the transmission case. Pour your used oil from the drain pan into a sealable container for recycling.
Common Problems with Can-Am DS 70 Gearbox Oil & How to Spot Them
Being aware of potential issues is a core part of our can am ds 70 gearbox oil tips. Here are a few things to watch out for during your service.
Milky or Foamy Oil
If the drained oil looks like a chocolate milkshake, it means water has gotten into the gearbox. This is common after riding through deep water or mud. Water is a terrible lubricant and will cause rust and rapid wear. If you find this, you should change the oil, ride for a short period, and change it again to flush the system completely.
Excessive Metal Shavings
As mentioned, a small amount of fine metal “fuzz” on the magnetic drain plug is normal. However, if you find large flakes, slivers, or chunks of metal, it’s a sign of a significant internal problem, like a chipped gear or failing bearing. At this point, it’s best to have a qualified technician inspect the transmission.
Leaks from Plugs or Gaskets
A common cause of leaks is reusing old crush washers. These small, soft metal gaskets are designed to be used only once. They crush slightly when tightened to create a perfect seal. Reusing them can lead to slow, messy leaks. Always use new ones—they’re incredibly cheap insurance.
Can-Am DS 70 Gearbox Oil Best Practices for Longevity
Beyond just changing the fluid, a few simple habits will ensure your ATV’s transmission stays healthy for the long haul. This is the essence of a good can am ds 70 gearbox oil care guide.
- Check It Regularly: Even if it’s not time for a change, periodically check the oil level via the fill plug, especially if you suspect a leak.
- Follow the Service Interval: Your owner’s manual will recommend a change interval based on hours or months. For a youth ATV that sees frequent, hard use in dusty or wet conditions, it’s wise to change it more often.
- Use a Torque Wrench: If you have one, use a torque wrench to tighten the drain and fill plugs to the factory specification. This prevents stripped threads and ensures a perfect seal without overtightening.
Frequently Asked Questions About Can-Am DS 70 Gearbox Oil
What kind of oil does a Can-Am DS 70 use?
The Can-Am DS 70 typically requires an SAE 80W-90 API GL-5 Hypoid Gear Oil. However, you must always confirm the exact specification in your owner’s manual for your specific model year, as requirements can sometimes change.
How often should I change the gearbox oil on my DS 70?
The manufacturer’s recommendation is the best starting point. A general rule of thumb for youth ATVs is to change the gearbox oil at least once a year or every 25-30 hours of ride time. If the ATV is ridden frequently in water, mud, or deep sand, you should change it more often.
Can I use car gear oil in my ATV?
Yes, as long as it meets the specifications required by Can-Am. An 80W-90 GL-5 gear oil from a reputable automotive brand is perfectly suitable for use in the DS 70’s separate gearbox. Just be sure not to use it in a “wet clutch” system where the engine and transmission share oil, which is not the case for the DS 70.
What happens if I put too much oil in the gearbox?
Overfilling the gearbox can cause pressure to build up, potentially blowing out seals and creating leaks. It can also cause the oil to foam up, which dramatically reduces its ability to lubricate properly, leading to increased heat and wear. Always fill to the level specified in the manual.
Taking care of your Can-Am DS 70’s gearbox is a simple, rewarding task that pays huge dividends in reliability and performance. By following this guide, you’ve empowered yourself to perform a critical service that will protect your investment and keep the trail rides fun and trouble-free.
