Oil Pump Rotor for Sea-Doo

This oil pump rotor is an internal engine component that drives oil circulation through the 1503 engine, and it carries OEM cross-reference 420956675.

Overview

The oil pump rotor is a rotating engine part that moves oil through the lubrication circuit so critical surfaces stay coated under load. Built for the Sea-Doo GTX LTD S/C 1503 platform, this rotor keeps oil pressure steady during long rides and hard acceleration. It suits riders and mechanics refreshing the oiling system on a 2003 or 2004 machine.

Specs At A Glance

Good To Know

Q: How do I know the oil pump rotor needs replacing? A: Scoring, visible wear on the rotor lobes, or a drop in oil pressure during a rebuild all point to replacement. Inspect the pump housing bore at the same time since wear there affects sealing.

Q: Does this rotor require an oil change after installation? A: Yes, fresh oil and a new filter should follow any oil pump service. Prime the pump before the first start so oil reaches the bearings quickly.

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