Over the years Primo/Rivera have changed the construction of stock replacement Pro-Clutches, as well as Pro-Clutches as supplied with Brute Classic, Brute III, and Brute IV belt drives. The early style Pro-Clutch had a clutch hub with a bolted-on steel rear plate, the late style Pro-Clutch have a hub with a separate, floating rear plate. Please note that Pro-Clutches used for stock replacement and the Pro-Clutch as supplied with a Primo belt drive are NOT the same!
