Abstract:
1. A pulley adaptor for installation on an existing engine pulley for converting an existing drive belt into a surpertine drive belt, the engine pulley mounted on a central drive shaft of the engine and defining an outer periphery, the engine pulley having an engine pulley depression located centrally in a side surface of the engine pulley with said engine pulley depression defining a radially inwardly facing engine pulley cylindrical surface; comprising a one piece pulley adaptor having a substantially cylindrical shape defining substantially planar surface having a first exterior surface and a second interior surface; a central aperture defined in substantially said planar surface of said one piece pulley adaptor; a cylindrical side wall of said substantially cylindrical shape extending from said second interior surface of said substantially planar surface having a height and an exterior surface to accommodated the serpentine drive belt; a plurality of grooves defined in said exterior surface of said cylindrical side wall for engaging with the serpentine drive belt; a recess defined in said second interior surface of said substantially planar surface of said one piece pulley adaptor dimensioned to overlay the outer periphery of the engine pulley; a shoulder extending from said second interior surface of said substantially planar surface of said one piece pulley adaptor defining a radially outwardly facing pulley adapter cylindrical surface being received within the engine pulley depression of the engine pulley and with said radially outwardly facing pulley adapter cylindrical surface engaging with said radially inwardly facing existing pulley cylindrical surface for centering the one piece pulley adaptor relative to the existing engine pulley; a plurality of through apertures extending through said substantially planar surface between said first exterior surface and said second interior surface of said planar surface of said one piece pulley adaptor; and a plurality of attachers extending through said plurality of through apertures of said one piece pulley adaptor for engaging with the engine pulley for securing said one piece pulley adaptor to the engine pulley.
