S&S Generator crankcase 65-69 Stock bore

S&S Big Twin Generator style crankcases are designed to appear like stock original cases and give the engine builder an alternative to costly repairs when fixing fatigued, broken, wornout stock crankcases. In spite of the stock appearance, these cases incorporate updated design features that improve overall engine strength and reliability. These cases are designed to fit steel or alloy primary on 1965 Panhead and 1966-1969 generator Shovelhead, and use with 1936-1969 style oil pump. Cases come complete with hardware, cylinder studs, crankcase bolts, and Timken style sprocket shaft bearings.
