Billet aluminum polished oil pump from S & S Cycles, fits Harley-Davidson Big Twins 1973-1991. Features & Benefits: 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 by 25% over stock on 1972 and earlier engines.
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 & reduces the amount of oil returned to the tank, less foaming and cavitation.
The delivery includes the oil pump with cover, fixing screws, connections, seals and installation instructions in english.
For Big Twins from 1981 up, require no modifications when using rigid lifters. In the years of construction 1973 to 1980 changes to the pump housing are necessary.
