Motorshop Knucklehead Oil Pump Governor Rotor for Harley EL and FL

The Motorshop Knucklehead Oil Pump Governor Rotor regulates oil pressure in vintage Harley-Davidson engines with a precision-ground centrifugal valve and an oiled finish. It is designed to be driven by the scavenger oil pump idler gear, delivering reliable lubrication across a range of engine speeds.

• Designed to bypass oil at low and intermediate speeds to prevent excessive pressure buildup and protect engine components.
• As engine speed increases, the rotor gradually tightens, allowing pressure to reach the set threshold and triggering the pressure regulating valve to bypass oil as needed.
• Engineered for Harley Davidson EL and FL models from 1941 to 1949; provides a precise fit and straightforward installation.
• Manufactured in Taiwan to OEM specifications with cross-reference 26300-41.
• Contributes to consistent oil flow and longevity of the lubrication system, supporting smooth operation across conditions.

Whether restoring a classic or performing maintenance, this rotor is a trusted choice for vintage Harley enthusiasts seeking to preserve authenticity and performance.
