Key Features

• Standard replacement engine oil pump for stock applications
• Steel gears and cast iron housing for durable construction
• Precision-ground end plates for improved wear resistance
• Individually tested for pressure and flow before release
• Includes gasket or seal for installation preparation
• Rust-preventative finish helps protect the pump surface

Detailed Description

The Melling M-66C is an engine oil pump engineered for a wide range of Chrysler, Dodge, and Plymouth V8 and inline applications from 1960 through 1987. It is built with a cast iron housing and cover, steel gears, and a drive-shaft-driven gear pump design. The standard pressure and standard volume configuration makes it a direct service replacement for stock engine oiling systems where original-style operation is required. This part cross-references Continental 50036 and Sealed Power 224-4165C for the same application. The M-66C is a practical choice for restoring oiling performance in vehicles such as the Dodge Dart, Dodge Charger, and Plymouth Fury.

What It Is Used For

• Low or inconsistent engine oil pressure
• Worn pump gears or internal pump wear
• Oil circulation issues in stock engine builds
• Restoration of original-style oiling system operation
• Replacement of a failed gear-type oil pump

Installation Notes and Tips

Verify engine application, pump style, and mounting pattern before installation. This pump uses a drive shaft design and a four-hole mounting pattern, so matching the original engine configuration is important. Confirm gasket or seal placement and inspect the mating surfaces for wear or debris before assembly. The M-66C is listed for stock applications across many classic Dodge, Chrysler, and Plymouth models, including Dodge Dart, Dodge Charger, and Plymouth Fury fitments.
