ABSTRACT:
A pulley spacer for use with internal combustion racing engines that is a circular disc of a predetermined thickness for spacing the racing pulley from the engine to retain alignment of the racing pulley-water pump pulley drive belt. The disc includes an obverse face and a reverse face. The disc includes a centrally located aperture through the disc and the obverse face includes a groove of a predetermined width concentric with the aperture. The reverse face includes a circular flange of a predetermined width concentric with the aperture. The groove and circular flange mate, with very tight fit, with a corresponding flange and groove on the racing pulley and a standard balancer, respectively, to allow transmission of engine torque without shearing the bolts used to assemble the racing pulley-pulley spacer-standard balancer assembly.
