BCBC M-57A Engine Oil Pump

Engine Oil Pump Overview

The Melling M-57A engine oil pump is a standard replacement pump built for dependable oil pressure and efficient circulation. It is made in the USA and uses gear and gerotor technology, with close-tolerance machining for consistent operation.

Compatible with 1964-1966 Ford F-100, 1964-1966 Ford F-250, and 1964-1966 Ford F-350, this oil pump is a direct service part for stock applications. The M-57A is also a fitment match for classic Ford truck engine rebuilds where standard pressure and standard volume are required.

• Steel gears and cast iron housing for durable pump construction
• Standard pressure and standard volume output
• Precision-ground end plates for improved wear resistance
• Individually tested for pressure and flow under operating conditions
• Gasket or seal included for service installation

Detailed Product Information

Melling M-57A is engineered as a gear-type oil pump with a drive shaft design, cast iron housing, and cast iron cover. The pump uses steel gears, a rust preventative finish, and a 0.630-inch inlet size. It is built with two mounting holes and a standard replacement grade, making it suitable for stock-style engine service where consistent lubrication is critical. This part cross-references Continental 50052 for the same application.

For Ford F-100, Ford F-250, and Ford F-350 engines from 1964-1966, the M-57A supports proper oil delivery in original-style builds and rebuilds. The pump is assembled to production standards and tested for pressure and flow before release.

What It Helps Address

• Low or inconsistent engine oil pressure
• Worn pump gears or internal pump wear
• Reduced oil circulation in a stock engine
• Service replacement needs during engine rebuilds
• Pressure and flow issues caused by pump fatigue

Installation Notes and Tips

Verify engine application, pickup tube size, and mounting dimensions before installation. This pump includes a gasket or seal, but no bolts, pickup screen, or drive shaft are included. Confirm the oil pump type and pressure requirements match the engine specification before assembly.

Quality Assurance

Melling manufactures this oil pump in the USA and tests each unit for pressure and flow under conditions that duplicate engine operation. Precision machining, close tolerances, and wear-resistant end plates support consistent service performance.
