The later "flanged-shaft" design incorporated the rear propeller mounting flange as part of the crankcase. Crankshafts, therefore, are either "taper" or "flanged"; and the correct engine suffix is directly associated with which crank is fitted. The distance between the front face of the propeller and the engine casting is increased approximately 1/2, and a new spinner approximately 3/8" longer is required. Refer to Ercoupe Service Memorandum No. 28 for full details. Regards, William R.
