420956675 Oil Pump Rotor for Sea-Doo GTS Pro 130 1503 2011

Oil Pump Rotor for Sea-Doo

This oil pump rotor is the replacement internal component that moves oil through the lubrication system in Sea-Doo 1503 four-stroke engines.

Overview

This oil pump rotor is a replacement lubrication component for Sea-Doo 1503 four-stroke engines, driven inside the oil pump to circulate oil under pressure. It serves owners and shops rebuilding or repairing an oil pump on GTX 155 and similar 1503-powered craft. Installing a fresh oil pump rotor restores oil flow to critical engine surfaces that depend on steady lubrication.

Built For Performance

• Replacement rotor made for the oil pump assembly on 1503 four-stroke engines
• Precision-formed lobes designed to move oil under pressure through the lubrication circuit
• Rugged material suited to continuous hot oil exposure in marine use
• Direct fit into the pump housing for rebuild or replacement service
• Service part number 420956675 for straightforward cross-referencing

Fits These Machines

• for Sea-Doo GTX 155 models from 2008 to 2013 with the 1503 engine
• for Sea-Doo GTX 155 models from 2015 to 2016 with the 1503 engine

On-The-Job Use

• Oil pump rebuilds and replacement on 1503 engines
• Top-end and full engine refresh projects
• Restoring oil pressure after a pump failure or loss of lubrication
• Routine maintenance on high-hour GTX 155 watercraft

Specs At A Glance

Good To Know

Q: How do I know if the oil pump rotor needs replacing? A: Scoring, pitting, or excessive clearance between the rotor and housing are common signs that it should be replaced. Loss of oil pressure on a 1503 engine also points to checking the pump internals.

Q: Should other oil pump parts be replaced at the same time? A: Rebuilds commonly include the mating rotor, cover, and seals in the same service to keep clearances within spec. Inspect all pump components before reassembly.

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