Note sprocket shaft: OEM sprocket shafts will not fit the 6° taper that S&S flywheels have; apart from 81-85 stock style B.T sprocket shafts (OEM 23909-80 / MCS 502615 and 502616). These will fit S&S flywheels but do not have the keyway that S&S sprockets shafts have. The woodruff key eliminates spinning of the sprocket shaft in the left flywheel. Note1: 58-81 B. T. pinion shaft assemblies also fit 54-57 B.T. when the stock pressed-in bearing race is removed and the cast-in bearing retainer is bored out to accept the larger 58-81 press-in bearing race (OEM 24599-58B / MCS 518110).Note: Special Order Product only. To order please contact your MCS sales representative.
