Oil PumpS
Oil PumpS
Fits 1973-’ 91 Big Twins. 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 standard pump cover allows total flexibility for oil system configuration with a number of oil feed and return options.

Fits1992-’ 99 HD ® big twins. Machined with an oil pressure relief bleed off valve to maintain consistent oil pressure from the time the engine is started to the time it’ s shut off. Oil pressure regulation bypass route allows excess oil not used by the engine to return directly to the supply side of the pump, reducing foaming and cavitation. No thicker than a stock pump. Equipped with a stock length oil pump drive shaft. Includes: Complete oil pump assembly, Oil pump driveshaft, Miscellaneous hose fittings, plugs and Paper gaskets with Mounting hardware. Gears and shims not included. Note: Chrome Plating the Pump & It is extremely difficult to chrome plate an oil pump without getting chrome in the passageways, cavities or on the machined surfaces where the gears, check ball, and pressure valve operates. Chrome in these areas as well as on the gasket surfaces impairs the pumps performance by altering the operating tolerances machined into the parts. In addition, abrasive particles of chrome may break loose causing damage to the pump and the engine. Because of this, S & S ® does not recommend chrome plating the pump body or cover. S & S ® voids its warranty if these parts are chrome plated.

If motor oil is the lifeblood of an engine, then the oil pump is its heart. If your engine needs a transplant, the new S & S ® three stage oil pumps are a great solution for worn out or destroyed stock units. Common causes of stock pump failure are debris and excessive pinion shaft run out. The new S & S ® oil pumps are much less likely to be damaged by either. Oh, and by the way, the new S & S ® oil pumps pump and scavenge way more oil than stock. While you’ ve got that motor apart, it would be a good time to install a new S & S ® TC3 forged cam support plate. Fits 1999-’ 06 HD ® big twin engines and 2007-’ 16 HD ® big twin engines. These pumps feature three stages for consistent pressure and reliable scavenging. Separate scavenge sections for flywheel cavity and cam chest- no interference. Screens and magnetic traps help protect the scavenge rotors from debris. These S & S ® pumps require. 005” or less runout and are Made in the USA! S & S ® oil pumps for 1999-’ 06 are not compatible with HD ® cam support plates for 1999-’ 06 engines. All S & S ® cam support plates are machined for 2007-later style oil pumps.
