Text excerpt from the catalog:
Over the years Primo/Rivera have changed the construction of stock replacement Pro-Clutches. The early style Pro-Clutch had a clutch hub with integrated steel rear plate, the late style Pro-Clutch have a hub and separate 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!
