OEM cases can\/may break in high performance or even stock applications, like more than a few of us found out the hard way. These S\u0026amp;S Superstock™ cases can be used for both stock replacement and racing applications. Important to the engine builder are the substantial savings in labor when using S\u0026amp;S cases. These cases come 'set up' with sprocket shaft Timken main bearing races and cam needle bearings installed and pinion shaft main bearing race pressed in and line-honed. Additional parts that are supplied include Timken sprocket shaft bearings, cylinder studs, nickel plated case bolts, crankcase fittings, oil pressure sensor, timing \u0026amp; magnetic crankcase drain plugs and a special S\u0026amp;S design alternator stator plug clamp screw. The flywheel scrapers are machined to match the original 8-1\/2\" diameter flywheels. S\u0026amp;S cases maximize crankcase oil scavenging efficiency by using a 'ported' design breather passageway. S\u0026amp;S cases are clearanced up to and including 5\", no additional clearancing for strokers will be necessary. S\u0026amp;S cases come complete with assembly instructions. \r\n\r\nNote: S\u0026amp;S crankcases for 36-54 Knuckle and Panhead models will not take OEM flywheels, pinion or sprocket shaft since late style (1955-up) Timken bearings are used in all S\u0026amp;S cases. 55-up shafts will not fit 36-54 OEM flywheels, S\u0026amp;S does not recommend machining 36-54 flywheels to take 55-up shafts. For all 36-55 B.T. applications 58-81 (MCS 512404) pinion \u0026amp; 55-64 (MCS 512401) splined sprocket shafts can be used with S\u0026amp;S flywheels, which all have a 6° shaft taper with keyway. \r\nNote: The 36-72 S\u0026amp;S oil pump (MCS 519922) can be used with all 36-69 S\u0026amp;S crankcases. \r\nNote: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components, prior to installation. It is of importance that a knowledgeable mechanic will install \u0026amp; make adjustments as required.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Crankcases\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 106-4369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":63007527928138,"sku":"MSH-512327","price":2434.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/512344k.jpg?v=1787164160","url":"https:\/\/partsdenmark.com\/products\/s-s-36-47-crankcase-assembly-3-5-8-bore-natural","provider":"Parts Denmark","version":"1.0","type":"link"}
