If you’ve spent any time wondering how the CVT, or continuously variable transmission, on your side-by-side works, you’re not alone. Even if you’ve found yourself replacing a belt trailside, you may not know exactly how the bits and pieces fit together, or why. For most of us, what happens behind that ubiquitous plastic cover is a mystery. The people at Polaris are out to shed some light on the CVT with the company’s latest Shop Talk video. In it, product expert Pat McArdle walks us through the basics, including the primary and secondary clutches as well as the belt itself. We even get a neat glimpse at the CVT in action without its cover in place.
