Beskrivelse
For use with a 'tin' (metal) primary housing. S&S Superstock™ crankcases, made from 356-T6 aluminum, are much stronger than the OEM case. 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&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&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 & magnetic crankcase drain plugs and a special S&S design alternator stator plug clamp screw. The flywheel scrapers are machined to match the original 8-1/2" diameter flywheels. S&S cases maximize crankcase oil scavenging efficiency by using a 'ported' design breather passageway. S&S cases are clearanced up to and including 5", no additional clearancing for strokers will be necessary. S&S cases come complete with assembly instructions. Note: S&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&S cases. 55-up shafts will not fit 36-54 OEM flywheels, S&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 & 55-64 (MCS 512401) splined sprocket shafts can be used with S&S flywheels, which all have a 6° shaft taper with keyway. Note: The 36-72 S&S oil pump (MCS 519922) can be used with all 36-69 S&S crankcases. Note: 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 & make adjustments as required.
