Oil Pump Rotor for Sea-Doo RXP 155 1503

The oil pump rotor for Sea-Doo RXP 155 1503 is an internal engine oil pump component that drives oil circulation through the 1503 engine; OEM cross-reference 420956675.

Overview

This oil pump rotor for Sea-Doo RXP 155 1503 keeps oil moving through the 1503 engine so bearings, cylinder walls, and valvetrain surfaces stay lubricated under load. It is the rotating element that generates oil pressure inside the pump housing on 2008 RXP 155 machines. Install one whenever the pump is opened for inspection or rebuild.

Good To Know

Q: Can this rotor be reused if it shows no visible wear? A: Wear on an oil pump rotor is often measured rather than seen, so replacing it during pump service is the safer route. Clearance checks against the housing are the reliable way to judge reuse.

Q: Does the oil pump need priming after installing a new rotor? A: Yes, the pump should be primed and oil pressure verified before the engine is run at load. Running dry even briefly can damage the new rotor and the engine bearings.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
