Harley Davidson Flathead 45 WLA, ULH, U, UL Early & Late Oil Pump Upgrade Rebuild. Designed to improve cylinder, piston and general cooling on all Harley Davidson Flathead Motors

Product Detail:

This is our newly developed oil pump professional rebuild for all 45 Big Twin Flathead Motors.

We have tested this oil pump system on our Bonneville motors for 5 years.

This pump has the ability to run piston squirters or a continuous feed crank with a 0.090 hole drilled in the end of the pinion shaft. This pump delivers double the flow and a maintainable 20 psi.
(Requires you send your pump in.)

(Oil pump caps, springs and balls will be extra if not supplied with the pump).

Rebuild includes our special oil pump gasket, .007. and also includes machining of the check seats.

USA made Difference between the long and short rotor will depend on the model of your oil pump. There is a narrow pump that only has 2 bypass caps or the wide body pump which has 3 bypass caps. The 2 bypass caps would get the short rotor and the wide body pump would get the long rotor.

Please specify tall or short rotor. Short/Narrow Body Pump Rotor: Measures: .625 Tall/Wide Body Pump Rotor: Measures: 1.125
