It’s the first thing your engine interacts with before that power actually moves you forward. The primary clutch looks kind of like a couple plates smashed together with some xtra hardware on the backside of one. Those dplates are the sheaves, they’re what the belt rides on. It rides higher or lower on the sheaves depending on how far apart (open) or how pushed together (closed) they are. The primary drive clutch for Polaris on UTV's can also be known as a CVT clutch. CVT stands for “Continuously Variable Transmission,” which means it changes gears without changing gears. A CVT clutch changes its shape so the clutch drive belt does not have to shift. That means it can stay in the optimal RPM range all the way until you hit the mechanical limitations of the clutch
