BEARING SUPPORT FOR OPEN BELT DRIVE ON 4-SPEED BIG TWIN

Running an open belt drive on 1970-early 1984 4-speed Big Twin normally means you lose the main shaft support from the inner primary housing. This bearing support is the solution for models with chain final drive. Does not fit Big Twin originally supplied with final belt drive or late 1984-1986 Big Twin originally supplied with a diaphragm clutch.

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.
