S&S, 70-84 Crankcase Assembly, Standard Bore. Natural For Harley Davidson

S&S Superstock™ crankcases, constructed from 356-T6 aluminum, are much stronger than OEM crankcases.
OEM crankcases can crack in high-performance or even stock applications, as many of us have found out the hard way.
These S&S Superstock™ crankcases can be used for both stock and competition replacement applications.
The important thing for the engine manufacturer is the substantial savings in labor that comes with using S&S crankcases.
These crankcases come "set up" with Timken sprocket shaft main bearing races and cam needle bearings installed and pinion shaft main bearing race pressed and ground.
Additional parts supplied include Timken sprocket shaft bearings, cylinder studs, nickel-plated crankcase bolts, crankcase fittings, oil pressure sensor, timing and magnetic crankcase drain plugs, and a specially designed S&S alternator stator plug retaining screw.
Flywheel scrapers are machined to match original 8-1/2" diameter flywheels.
S&S cases maximize crankcase oil scavenging efficiency by using a "ported" design vent passage.
S&S cases have clearance up to and including 5", so no additional clearance will be necessary for race engines.
S&S boxes are delivered complete with assembly instructions.
Note: The HD Aluminum Oil Pump (26190-73) or the S&S Oil Pump, MCS 519923, can be used on 70-91 applications.
Note: In each and every application, the technician must be able to evaluate the suitability of the components in combination with the other engine components, prior to installation.
It is important that an experienced mechanic installs and makes any necessary adjustments.
