ABSTRACT:
A composite flywheel assembly for an air-cooled internal combustion engine including a cast iron flywheel which provides the inertial drive for the engine and a separate blower member having a circumferential array of vanes for propelling a flow of cooling air past cooling fins of the engine. The blower member is a one-piece molded impeller of flexible plastic material and is releasably retained on the inertia wheel by a snap-on interlocking engagement about the outer periphery of the flywheel. The closed end of a starter cup is received over an engine crankshaft and engages a conical skirt extending inwardly from the impeller base to spring bias the impeller against the flywheel.
