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!

IMPORTANT INFORMATION Due to the wide application and fitting variations of primary and final belts, Zodiac can not accept any claim for warranty as, no matter how long they have been used and no matter what the defect is, belts are not covered by any manufacturer warranty. To avoid any complications we suggest that belts should be installed by a qualified mechanic.
