BCBC M-37 Engine Oil Pump

Engine Oil Pump Overview

This Melling engine oil pump is a standard replacement for classic Chrysler, Dodge, DeSoto, and Plymouth applications. Part number M-37 is built with steel gears, a cast iron housing, and a rust-preventative finish for dependable oiling performance in stock-style engines.

Key Features

• Standard replacement engine oil pump for vintage applications
• Steel spur gears with close-tolerance machining for consistent pressure
• Cast iron housing and cover for durable construction
• Gasket or seal included for service replacement
• Individually tested for pressure and flow before release

Detailed Description

The M-37 oil pump uses gear-type construction with standard pressure and standard volume output. Melling engineers the pump with precision-ground end plates to improve wear resistance, while the machined gears and gerotor technology support efficient operation under engine conditions. The 0.625-inch inlet size, two mounting holes, and included pump cover reflect a service-focused design for older engines that require a stock-style oiling solution. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with a wide range of classic Dodge, Chrysler, Plymouth, and DeSoto vehicles, this Melling M-37 is listed for many 1942-1968 applications, including Dodge Power Wagon, Dodge W300 Series, and Plymouth Belvedere. Fitment notes include standard gear and rotor-type-only configurations, so the original pump style should be verified before installation.

What It Is Used For

• Restoring proper engine oil pressure
• Replacing a worn or low-output oil pump
• Addressing inconsistent lubrication in stock engines
• Servicing classic engines that require a standard-pressure pump
• Supporting reliable oil circulation in vintage drivetrains

Installation Notes and Tips

Confirm the original pump style and fitment notes before ordering, especially on applications marked rotor type only with standard gear. Verify inlet size, mounting hole spacing, and drive type during installation. The pump includes a gasket or seal, but no drive shaft, bolts, or pickup screen are included.

Quality Assurance

Melling tests each oil pump for pressure and flow under conditions that simulate real engine operation. The M-37 is assembled to production standards using quality materials and precision-machined components for consistent service performance.
