Flywheels have the stock 8-1\/2\" diameter and are compatible with the flywheel scrapers found in both stock and S\u0026amp;S crankcases. \nCompatible with S\u0026amp;S Sprocket shaft assemblies: \n- 512401 55-64 B.T. with S\u0026amp;S SE \u0026amp; SL flywheels only \n- 512402 65-69 B.T. with S\u0026amp;S SE \u0026amp; SL flywheels only \n- 512403 70-99 B.T.

Repl. 24007-39. \n512404 58-E81 B.T. (See 'Note 1' for 54-57 models). \nNote sprocket shaft: OEM sprocket shafts will not fit the 6° taper that S\u0026amp;S flywheels have, apart from 81-85 stock style B.T sprocket shafts (OEM 23909-80 \/ MCS 502615 and 502616). These will fit S\u0026amp;S flywheels but do not have the keyway that S\u0026amp;S sprockets shafts have. The woodruff key eliminates spinning of the sprocket shaft in the left flywheel. \nNote1: 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).\nNote: Special Order Product only. \nTo order please contact your MCS sales representative.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Flywheels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 320-0649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":63217554096458,"sku":"MSH-708933","price":6724.0,"currency_code":"SEK","in_stock":true}],"url":"https:\/\/partsdenmark.se\/products\/s-s-flywheel-set-4-3-4-stroke","provider":"Parts Denmark","version":"1.0","type":"link"}
