SEALED NUT & CLUTCH ADJUSTER KIT

Primo has developed this sealed nut & adjuster kit for use with all open belt drives and other applications that require that no transmission fluid be allowed to leak through the transmission main shaft. Oil leakage may reduce belt life drastically. Recommended for use with any belt drive on 1990-2000 Evolution Big Twin & 1999-2006 Twin Cam using the OEM style main shaft.
