In the mid eighties the 11mm belt kit with 31 tooth engine pulley and 47 tooth clutch pulley was introduced. The large pitch tooth profile is preferred by many users. Kits for aluminum primary include a BDL idler that makes sure belt tension is correct. Tin primary models use transmission adjustment to achieve correct belt tension.

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.
