Servicing Your 900 Ace: A Comprehensive Oil Change Guide

Embarking on a snowmobile adventure is thrilling, but ensuring your machine is in peak condition is paramount. A crucial aspect of this is regular maintenance, and a 900 Ace oil change is a task any owner can tackle with a bit of guidance. This article will walk you through the process, from preparation to the final checks, ensuring you can keep your 900 Ace purring like a kitten, even after a demanding season.

Preparation is Key: What You'll Need

Before you get your hands dirty, gather the necessary tools and supplies. Having everything at the ready will make the job significantly smoother and quicker. For a 900 Ace oil change, you will typically require:

• New Oil: 3.7 US quarts of BRP 4-stroke synthetic oil is recommended. Always consult your owner's manual for the exact specifications.
• New Oil Filter: A genuine BRP oil filter cartridge.
• Sealing Washers: New sealing washers for the drain plug(s).
• Tools: Socket set or wrenches for the drain plug and filter cover screws, screwdrivers, a drain pan, rags, and possibly a torque wrench.
• Safety Gear: Gloves and eye protection are always a good idea.

Getting the Sled Ready for the Task

To access the drain plug and filter efficiently, you'll need to get your 900 Ace off the ground. The most effective way to do this is to ensure the sled is as level as possible. Raising it on sturdy timbers, ensuring both skis and the track are clear of the ground, provides excellent stability and access. This level position is vital for ensuring all the old oil can be drained effectively.

Locating and Removing the Drain Plug(s)

On the bellypan of the 900 Ace, you'll find an oval-shaped cover, approximately 2.5" x 4", secured by two screws. To access the drain plug, loosen one screw and remove the other, allowing the cover to swing open. You might notice what appear to be two drain plugs. For the 900 Ace, the correct plug to remove is typically the shorter one, which usually has a copper sealing washer. As the oil drains, it should flow directly into your waiting drain pan, minimising mess.

The Muffler: A Necessary Obstacle

Accessing the oil filter usually requires the removal of the muffler. While this might seem like an extra step, it's often a good idea to perform this at the end of the season anyway, as suggested by the owner's manual. The process of removing the muffler becomes easier with practice. Once removed, you'll have clear access to the oil filter housing.

Replacing the Oil Filter: A Detailed Look

The oil filter cartridge is nestled within a cavity, protected by a cover held in place by three small screws. After removing these screws, carefully extract the filter. It might be a bit snug within the cover. Take a moment to inspect the pleats of the old filter for any signs of debris. It's a good practice to save the old filter in a sealed bag, just in case any warranty questions arise later.

The new BRP filter should fit snugly into the filter cap. By this point, any residual oil in the filter cavity should have drained out. If not, you can assist the draining process by manually turning the engine over. Rotate the primary clutch by hand until the oil from the filter cavity has been expelled. For some, this might only take one revolution.

Once the old oil has drained and the new filter is in place within the cap, reinsert the cap, ensuring a new O-ring is fitted. Tighten the three screws securing the filter cover. Remember to replace the drain plug(s) with new sealing washers to prevent leaks.

Refilling and Initial Start-Up

With the new filter and drain plug secured, it's time to add the fresh oil. Carefully pour approximately 3.7 US quarts of BRP 4-stroke synthetic oil into the dipstick hole. Once filled, you're ready for the initial start-up. This is where you might want to brace yourself!

Important Note: If you haven't reinstalled the muffler, the sound of the 900 Ace engine without it can be quite startling and loud. For a temporary fix that still quiets the engine considerably, you can re-seat the muffler without attaching the springs. It might leak a little, but it will significantly reduce the noise. Start the engine and listen for the engine knock, which should cease within about four seconds as the oil circulates. After approximately ten seconds of running, shut down the engine.

Post-Start Checks and Final Reassembly

After shutting down the engine, it's crucial to perform some checks. Pull the muffler back out (if you temporarily re-seated it) and carefully inspect the drain plug area and the oil filter housing for any signs of leaks. Then, check the oil level using the dipstick to ensure it's at the proper mark. If all looks good, reassemble the muffler securely. Finally, reattach the small oval cover on the bellypan.

Chaincase Maintenance: A Synergistic Task

As mentioned, it's often convenient to perform chaincase maintenance while the muffler is already out. This can add approximately an hour to your overall service time, but consolidating these tasks can save you time and effort in the long run. Always refer to your owner's manual for the specific procedures related to chaincase servicing.

Cost Considerations

While the exact cost can vary depending on your location and any promotions, many owners report that a BRP oil and filter change for their 900 Ace typically costs around $50 when purchasing the products separately. Some dealers may also include maintenance kits as part of a purchase deal, which can offset these costs.

Concluding Thoughts

Performing a 900 Ace oil change yourself can be a rewarding and cost-effective maintenance task. By following these steps carefully and ensuring you have the right parts and tools, you can confidently keep your snowmobile in excellent running condition for many seasons to come. Remember, regular maintenance is the best way to protect your investment and ensure reliable performance on the snow.
