- 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
- 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
- S&S® pumps for 1936-'67 engines used with the S&S® oil pump drive gears deliver 33 percent more oil than the original cast iron pump
- Same width oil supply and return gears as the stock HD® aluminum pump
Upgrade your vintage Harley Davidson with the S&S Cycle 36-72 BT Billet Oil Pump Kit, designed specifically for models from 1936 to 1942. This high-performance pump features an oil pressure regulation bypass that routes excess oil directly back to the supply side of the pump, reducing foaming and cavitation while ensuring optimal lubrication. The machined relief bleed-off passage maintains consistent oil pressure by relieving pressure buildup on top of the valve, promoting reliable engine operation. Built with precision, this kit includes S&S pinion and oil pump drive shaft drive gears that increase potential oil volume delivery by 25 percent over stock units on 1972 and earlier engines, enhancing engine cooling and longevity. For engines from 1936 through 1967, the S&S pumps used with the corresponding oil pump drive gears deliver 33 percent more oil than the original cast iron pumps, providing improved lubrication and performance. The design maintains the same width as the stock Harley Davidson aluminum pump, ensuring a straightforward installation without modifications. Crafted from billet aluminum, this oil pump kit offers durability and precision engineering, making it a reliable upgrade for vintage Harley Davidson enthusiasts seeking to improve engine efficiency. The kit fits a range of Harley models, including E, EL, and FL series from 1936 to 1942, ensuring broad compatibility and ease of installation. Whether rebuilding or enhancing your classic Harley, this S&S Cycle oil pump kit provides increased oil flow, consistent pressure, and long-lasting performance, helping your vintage motorcycle run smoothly and reliably for years to come.
