S&S Oil Pump Kit for Harley-Davidson Big Twin 1936-1969

  • Same width oil supply and return gears as the stock HD aluminum pump
  • S&S pinion and oil pump drive shaft drive gears increase potential oil volume delivery over the stock design
  • Machined with an oil pressure relief bleed off passageway
    • Relieves pressure build up on top of the valve to maintain consistent oil pressure
  • Oil pressure regulation bypass routes excess oil directly to the supply side of the pump and reduces the amount of oil returned to the tank
    • Results in less foaming and cavitation
  • Standard pump cover allows total flexibility for oil system configuration with a number of oil feed and return options
  • Made in the USA

Product Note: Requires 1973-1977 breather gear, (sold separately).

Problem solved

By Mr.D on  Verified Purchaser

After having issues with over oiling/dumping with the stock oil pump, I decided to try he S&S Shovelhead oil pump. After modifying he engine case and installing the pump, the problem is resolved. For 40 years I've always trusted S&S for their innovative products.

Exceeds expectations
