The S&S Cycle SSC31-6205 universal oil pump kit is designed for select Harley Davidson models from 1992 and 1993, providing reliable oil pressure regulation and enhanced engine lubrication. This complete assembly includes the oil pump, driveshaft, miscellaneous hose fittings, plugs, paper gaskets, and mounting hardware, ensuring a straightforward installation process. Gears and shims are not included, allowing for customization based on specific engine requirements. The pump is engineered with a bypass route for excess oil, which helps reduce foaming and cavitation by returning unused oil directly to the supply side of the pump. This feature ensures smoother engine operation and consistent oil flow during various operating conditions. The pump body is machined with an integrated oil pressure relief bleed-off valve to maintain steady oil pressure from engine start-up through shutdown, contributing to optimal engine performance and longevity. The unit is equipped with a stock-length oil pump driveshaft and maintains the same thickness as a stock pump, ensuring compatibility with the original engine components. Additionally, the universal cover design simplifies fitting across various Harley Davidson models. It is important to note that S&S does not recommend chrome plating the pump body or cover, as doing so voids the warranty. This pump is suitable for air-cooled powersports engines and is compatible with a wide range of Harley Davidson models from the early 1990s, making it a versatile upgrade for enthusiasts seeking durable and efficient oil pump performance.
