Why do RZR belts break? The primary reason RZR belts break is excessive heat.
Buy the right belt with our buying guide on finding your Polaris RZR belt
It’s a question that haunts many a side-by-side enthusiast. The Polaris RZR is a fine machine, built for speed and adventure, but it seems that no matter how well you treat it, the belt just won’t keep up. So what gives?
Well, let’s start with the basics. The RZR’s drive belt, also known as a CVT belt, is a crucial component of the machine’s clutch system. It transfers power from the engine to the transmission, and if it fails, you’re stuck on the trail. It’s a part that sees a lot of stress, especially in high-speed situations, so it’s no surprise that it can wear out over time.
But why does it wear out so quickly? There are a few factors at play. First and foremost, the clutch itself can put a lot of strain on the belt. The primary clutch, which is connected to the engine, grips the belt and spins it around. The secondary clutch, on the other end of the belt, controls the speed of the machine. When you’re going fast, the belt is working hard to keep up, and it can get worn down quickly.
Another factor is heat. When the belt gets too hot, it can start to glaze over, which means the surface becomes smooth and glassy. This reduces the belt’s width and can lead to slippage, which puts even more stress on the clutch system. To keep the belt cool, it’s important to make sure there’s plenty of airflow around the clutch. Some models have built-in vents, but if yours doesn’t, you may want to consider adding some.
Finally, it’s worth noting that not all belts are created equal. A new belt may be more resistant to failure than an old one that’s been through a lot of abuse. If you’re experiencing frequent belt failure, it may be time to invest in a higher-quality belt that can stand up to the rigors of high-speed riding.
In conclusion, belt failure is a common issue among Polaris RZR owners, but there are steps you can take to extend your belt’s life. Keep your clutch system in good working order, make sure the belt stays cool and well-ventilated, and consider upgrading to a higher-quality belt if necessary. With a little care and attention, you can keep your RZR running smoothly for years to come.
