How to Inspect and Clean the CVT System on Your Can-Am Maverick the Right Way
Owning a Can-Am Maverick means you have one of the most capable and powerful side by sides on the market. Whether you are racing through open desert or climbing technical trails, the performance of your machine depends heavily on the Continuously Variable Transmission. This system is responsible for converting the high horsepower of the Rotax engine into usable torque at the wheels. Because the CVT on a Maverick is an open air cooled system, it is constantly exposed to the elements, including dust, sand, water, and heat.
If you neglect the cleanliness of your CVT, you will quickly notice a drop in performance. Dust and debris act as abrasives that wear down the metal sheaves of your clutches and the rubber of your belt. Over time, this buildup can lead to belt slippage, erratic shifting, and even catastrophic belt failure. For the DIY mechanic, learning how to inspect and clean the system the right way is the best insurance policy against an expensive repair. This guide provides a step by step approach to maintaining your Maverick drivetrain for maximum reliability.
Preparing Your Maverick for a Deep CVT Cleaning
Before you start pulling bolts, it is important to have a clean workspace. Working on a CVT system requires precision, and you do not want to introduce more dirt into the clutches while you are trying to clean them. Start by pressure washing the exterior of your Maverick, paying close attention to the area around the CVT cover on the driver side of the machine. Once the area is dry, gather the necessary tools:
- A socket set with an extension to reach the cover bolts.
- A belt removal tool, which is often included in the factory tool kit.
- Compressed air with a long reach nozzle.
- Non chlorinated brake cleaner or a specialized clutch cleaner.
- A clean, lint free microfiber cloth.
- A green or red abrasive scuff pad for the metal surfaces.
Removing the CVT cover on a Maverick can be tight depending on whether you have a base model or an X3 with extra bracing. Take your time and ensure you do not tear the large rubber gasket that seals the cover to the inner housing. This gasket is your primary defense against water entering the system during creek crossings, so its condition is vital.
Removing and Inspecting the CVT Belt
Once the cover is off, the first task is to remove the belt. Use the belt removal tool to spread the sheaves of the secondary clutch, which creates slack in the belt and allows you to slide it over the top. Once the belt is out, do not just toss it aside. It is a diagnostic tool that can tell you exactly how your clutches are performing. Inspect the belt for the following signs of trouble:
- Look for glazing on the side walls, which appears as a shiny or burnt surface.
- Check for any missing teeth or cracks at the base of the cogs.
- Inspect the edges for fraying strings, which indicates an alignment issue.
- Feel for flat spots, which are caused by the belt smoking in one place while the machine was stuck.
- Measure the width of the belt with calipers to see if it has worn below the service limit.
If the belt looks healthy, set it aside in a clean area. If you see any signs of thermal damage or excessive wear, it is better to replace it now while the machine is already apart. A compromised belt might look fine at a glance, but the internal cords could be stretched, leading to an unexpected snap on your next aggressive ride.
Cleaning the Primary and Secondary Clutches
The clutches are the most complex part of the Maverick drivetrain. As they spin, they act like a vacuum, pulling in air to stay cool. Unfortunately, they also pull in fine dust that settles into the moving parts of the primary clutch. This dust can jam the rollers and weights, preventing the clutch from shifting smoothly. To clean the clutches properly without full disassembly, follow these steps:
- Use compressed air to blow out the primary and secondary clutches thoroughly.
- Wear a mask during this process, as the belt dust can be harmful to inhale.
- Rotate the clutches by hand as you blow them out to reach all the internal pockets.
- Use a scuff pad to lightly sand the faces of the sheaves where the belt rides.
- Wipe the sheave faces down with brake cleaner and a clean cloth until no black residue remains.
- Inspect the rollers in the primary clutch to ensure they spin freely and do not have flat spots.
It is important to avoid getting any lubricants like grease or oil on the sheave faces. Even the oils from your skin can cause the belt to slip. If you notice that the rollers or sliders are stuck even after a thorough cleaning with air, you may need to look into a clutch rebuild kit to restore factory performance.
Inspecting the Housing and Cooling Ducts
While the belt is off and the clutches are clean, take a moment to look at the rest of the CVT environment. The inner and outer housings should be free of cracks or warping. Check the air intake and exhaust ducts for any obstructions. On the Maverick, these ducts are designed to move a high volume of air, but they can easily become clogged with mud or debris from the trail.
- Examine the intake screen for any buildup of leaves or desert brush.
- Look inside the exhaust duct to ensure there are no pieces of an old broken belt stuck in the piping.
- Check the condition of the housing bearings if your specific model uses a supported cover.
- Ensure the drain plug at the bottom of the CVT cover is tight and the O ring is in good shape.
If you have ever broken a belt in the past, it is common for small chunks of rubber to get pushed into the cooling snorkels. These fragments act like a dam, restricting airflow and causing the next belt to overheat quickly. Using a vacuum or a long flexible brush to clear these passages is a critical step that many owners skip.
Reassembling the System for Maximum Longevity
When you are ready to put everything back together, the order of operations matters. Slide the belt back over the primary clutch first, then work it onto the secondary. Ensure that the arrows on the belt are pointing in the direction of engine rotation, which is typically toward the front of the vehicle on a Maverick. This ensures the belt plys are working in the direction they were designed for.
- Cycle the secondary clutch to let the belt ride back up to the top of the sheaves.
- Rotate the drivetrain by hand a few times to ensure the belt is seated properly.
- Carefully align the CVT cover gasket and start all the bolts by hand to avoid cross threading.
- Tighten the cover bolts in a crisscross pattern to ensure even pressure on the seal.
Before you go out for a full speed run, it is wise to start the engine with the vehicle in neutral and let it idle for a minute. This allows the belt to find its natural center. If you installed a brand new belt, remember that it requires a break in period of light to moderate throttle for the first several miles to ensure the rubber is seasoned correctly.
Frequently Asked Questions
Can I use soap and water to clean my clutches?
It is generally better to stay away from soap and water inside the clutches because it can be difficult to dry out the internal bushings and rollers. Compressed air and a specific electronics or brake cleaner that evaporates quickly are the preferred choices for DIY maintenance.
How often should I clean the CVT on my Maverick X3?
If you ride in extremely dusty or sandy conditions, you should consider a quick cleaning every 200 to 300 miles. For casual trail riding, an inspection and cleaning every 500 to 700 miles is usually sufficient to keep the system in top shape.
What happens if I put the belt on backward?
While the belt will technically function, the internal cooling fins and the way the cord is wrapped are often directional. Running a belt backward can lead to increased heat and a shorter overall lifespan for the component.
Do I need to lubricate the primary clutch rollers?
No, the CVT system on the Maverick is designed to run dry. Adding grease or oil to the internal components will only attract more dust, creating a thick paste that will cause the clutch to stick and fail prematurely.
Why is there black dust inside my CVT cover?
A small amount of black dust is normal, as it is the result of natural belt wear. However, if you find piles of thick rubber dust, it is a sign that your belt is slipping excessively or that your clutches are out of alignment.
