Tips on how to change a worn out or broke ATV CVT Belt


It is far less likely that an ATV’s Continuously Variable Transmission (CVT) belt will break in comparison to UTVs. Quads are much lighter in weight and don’t put as much stress on the belt as an UTV would. However, we managed to have a belt go bad in our 2019 Can-Am Renegade X xc 1000R by getting it too hot during some spirited riding. Mind you, this is a very rare occurance, but you should consider changing your ATV’s CVT belt over time. They do get worn out, and that means less reliability, slippage and a loss of power. This How-To will show you how to change the Renegade’s CVT belt. The task isn’t too difficult, but you need the right tools for the job.

-3/8-inch ratchet
-10mm socket
-8mm socket
-6-inch long 3/8-extension
-3-inch long 3/8-inch extension
-10mm combo wrench
-T-30 torx socket

NOTE: You will need to go to your local hardware store and purchase an 8mmx1.25 bolt that is at least 50mm in length to get the CVT secondary clutch sheaves to separate enough to remove the CVT belt. Some of the bolt heads may be different sizes. Ours was 13mm.

In this How-To, we decided to remove the foot peg, foot well and the support. We did this to gain easier access to the CVT cover. The bolts on the bottom edge of the cover are difficult to get to and will take a while to unscrew if you leave the foot well parts on. We utilize a 3-speed electric impact wrench to REMOVE bolts and nuts. ALWAYS thread screw, bolts and nuts by hand before using an electric impact wrench on hardware. We suggest that you do not use the impact wrench for any of the tightening process since it can easily strip threads and break parts. We leave that choice up to you! Lets begin.

This is where we start. You can see the CVT cover in this photo along with the foot well and peg. It is easiest to unscrew the CVT case and remove it with these parts out of the way.

Start by removing the nuts and bolts from the foot well that connect with the upper plastics. A T-30 Torx and a 10mm socket will be utilized. We assume that on some machines, plastic clips will be utilized to hold these plastic together, but this used model came to us with nuts and bolts.

The rear of the footwell will also need to be disconnected from the rear plastic. It is smart to use an electric impact wrench on a low setting for removing parts. It is wise to use hand tools first if the hardware wont break loose easily.

There are two bolts, one on either side of the foot peg that connects the foot well to the platform underneath. The platform has a nut insert molded into the plastic so you only need to remove the bolts since there are no nuts.

The foot pegs are next. You will need a 10mm wrench for the top two bolts and a 10mm socket on your ratchet wrench and extension for the nuts.

At this point, the foot well and peg can be removed to gain access to the platform underneath.

There are four 10mm nuts that hold the platform onto the Renegade’s frame. The bolts are inserted through the bottom and are channeled into the frame. All you need to do is hold the bolts from the bottom so the nuts can be removed from above.

Now with the footwell and mounting platform out of the way you can easily gain access to the CVT cover from all angles.

The CVT cover mounting bolts are easy to remove and use rubber grommets to hold them to the cover. There are quite a few of these bolts to remove.

The bolts on the bottom are much easier to get to with the footwell removed. An 8mm socket is needed for all the CVT cover bolts.

The cover is easy to remove and take off. Take care not to let the bolts fall out of it unless you are keeping track of them. There is a rubber seal on the cover that should be cleaned if it is dirty.

With the CVT now visible, you can assess the belt and clutch. Make sure to clean out any debris you find in there. Our case was relatively clean, and the belt didn’t shred apart.

In order to remove the belt, you will find a threaded hole on the secondary. The bolt you need to use will needed to be threaded into this hole to spread the sheaves.

Use your ratchet and the respective socket to tighten the bolt. It will stop when it reaches the limit of the sheave’s travel. Do not use too much force on it.

To remove the belt, start by pulling it towards the rear of the Renegade while slipping it over the top of the sheave. It shouldn’t be to difficult to manipulate off since the belt is worn in. If your belt decided to string apart instead of just snap or break teeth off, you’ll be spending time cleaning the mess out. Make sure the sheaves are clean before inserting the new belt. A few paper towels and some contact cleaner will aid this process. Click HERE for more CVT belt changing info and techniques.

Our Can-Am Renegade CVT belt broke a few teeth off. We made sure we found them and removed them from the CVT case during our cleaning process.

The new CVT belt that we got from Can-Am has an imprint that specifies direction of rotation. The CVT turns the belt counter clockwise in operation for the 1000R.

Once our CVT case and sheaves were cleaned and ready to go, we slipped the belt over the primary clutch and started feeding it over the secondary. We start feeding it from the bottom, around the rear and then over the top.

The new belt will be a bit tighter, so we inched our way around the sheave with our thumbs, pushing firmly as we went.

The last little bit slid over the sheave and the belt was on.

With the CVT belt properly installed, we can move onward to close the secondary clutch sheaves.

Remove the bolt out of the secondary clutch and the install of the new CVT belt is almost complete.

We decided to run the Can-Am to make sure there weren’t any issues with the new belt before putting the machine back together. This can be VERY DANGEROUS. We don’t suggest doing this unless you are EXTREMELY careful. The fast spinning CVT clutch can easily injure you or anyone assisting you. Keep ALL parts of your body, clothes, tools and anything that make come in contact with the clutch far away from it.

Now it is time to reinstall all the parts. The CVT cover bolts thread in the the case. The case is plastic, so thread them in carefully by hand when you install the cover so you do not strip the case threads.

Utilize hand tools to tighten all the case bolts and the rest of the hardware on your Renegade. Make sure to follow torque specifications required for your machine. You can purchase a manual for your Can-Am at your local dealer, or online through multiple sites.
