Key Features

• Standard replacement oil pump and timing cover assembly
• Crankshaft-driven design for direct engine operation
• Cast iron cover with aluminum housing
• Powdered metal rotor construction
• Rust preventative finish for added surface protection
• Gasket and O-ring included
• Individually tested for pressure and flow

Detailed Description

Melling M507 is an engine oil pump and timing cover assembly designed for applications that require standard pressure and standard volume oil delivery. The pump uses gear and gerotor technology, with machined gears and precision-ground end plates to promote efficient pumping and wear resistance. Its cast iron cover, aluminum housing, and powdered metal rotor reflect a durable construction suited to routine engine service. This M507 assembly is a practical choice for Mitsubishi Eclipse, Mitsubishi Galant, Mitsubishi Lancer, and Mitsubishi Outlander applications listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part May Address

• Low oil pressure caused by pump wear or internal leakage
• Inconsistent oil delivery from a worn pump assembly
• Noise or wear related to reduced lubrication performance
• Seal-related oil seepage at the pump and cover interface

Installation Notes and Tips

Verify engine application, drive type, and mounting-hole pattern before installation. Replace the gasket and O-ring during service, and inspect the mating surfaces for cleanliness and flatness. Confirm proper oil pressure after installation to ensure the pump is operating within specification.

Quality Assurance

Melling manufactures this assembly to production standards and individually tests each unit for pressure and flow under conditions that simulate engine operation.
