- Oil pressure regulation bypass routes excess oil directly to the supply side of the pump & reduces the amount of oil returned to the tank, less foaming and cavitation
- Ideal for scratch built applications where the builder is starting out with aftermarket crankcases, or older engines where a complete overhaul is required
- Machined with an oil pressure relief bleed off passageway & relieves pressure build up on top of the valve to maintain consistent oil pressure
- S&S® pinion and oil pump drive shaft drive gears increase potential oil volume delivery by 25 percent over stock on 1972 and earlier engines
- The standard pump cover allows total flexibility for oil system configuration with a number of oil feed and return options
- Same width oil supply and return gears as the stock HD® aluminum pump
The S&S Cycle Part Number 31-6294 oil pump kit is a comprehensive solution designed specifically for Harley Davidson models from 1970 to 1975, including FLH Electra Glide and FX Super Glide. This kit includes a complete oil pump assembly, mounting hardware, fittings, gaskets, and essential components such as the pinion shaft pump drive gear, oil pump drive shaft gear, and breather gear. Built for precision and durability, this assembly ensures optimal oil flow and pressure regulation to support high-performance engine needs. The oil pressure regulation bypass routes excess oil directly to the supply side of the pump, reducing foaming and cavitation by minimizing the amount of oil returned to the tank. This feature helps maintain consistent oil pressure, extending engine life and improving overall performance. Designed for custom applications, especially when working with aftermarket crankcases or during engine overhauls, the kit offers flexibility with its standard pump cover that allows various oil feed and return configurations. Machined with an oil pressure relief bleed-off passageway, it effectively relieves pressure build-up on the top of the valve, ensuring steady oil flow under different operating conditions. Additionally, the inclusion of S&S pinion and oil pump drive shaft gears increases potential oil volume delivery by 25 percent over stock components on 1972 and earlier engines, providing enhanced lubrication and cooling. The kit features the same width oil supply and return gears as the stock Harley Davidson aluminum pump, ensuring compatibility and ease of installation. Whether restoring an older engine or customizing a new build, this oil pump kit delivers reliable performance and improved oil management for Harley Davidson enthusiasts seeking durability and efficiency. The kit's design and components are engineered to meet the demands of powersports applications, making it a trusted choice for professional mechanics and DIY builders alike.
