ABSTRACT:
A process for forming a balanced flywheel assembly from a cast metal hub having at least one cast-in pick up and a ring gear having an inside shrink-fit surface with a predetermined diameter at ambient temperature by heating a ring gear sufficiently to cause the diameter of the inside shrink-fit surface to become larger than the diameter of a ring gear mounting surface of the cast metal hub, mounting the ring gear on the ring gear mounting surface, cooling the ring gear to shrink fit the ring gear onto the ring gear mounting surface, and balancing the cast metal hub and the ring gear assembly; various surfaces being formed on the cast metal hub by turning.
