BCBC M342 Engine Oil Pump

Overview

The Melling M342 engine oil pump is a standard replacement part built for dependable oil delivery and consistent pressure control. It is made in the USA and uses rotary pump design, close-tolerance machining, and precision-ground end plates for efficient operation.

Compatible with Chrysler, Dodge, and Jeep applications, including Chrysler 300, Dodge Charger, and Jeep Grand Cherokee models in the listed fitments. The M342 is a practical choice for stock-style engine service where stable oil flow matters.

Key Features

• Standard replacement oil pump with standard pressure and standard volume output
• Rotary design with gear and gerotor technology for efficient pumping action
• Aluminum housing and cover with rust-preventative finish
• Powdered metal rotor and precision-ground end plates for wear resistance
• Gasket or seal included for service installation
• Individually tested for pressure and flow under operating-condition simulation

Detailed Description

The Melling M342 oil pump is engineered for stock applications that require reliable lubrication performance. Its crankshaft-driven rotary design, aluminum construction, and close-tolerance internal machining support consistent oil pressure across the listed Chrysler, Dodge, and Jeep fitments. This part cross-references Mopar (e.g., 53021622AF) for the same application.

Use the M342 when replacing a worn or inefficient pump in engines that call for standard pressure and volume output. The M342 part number is commonly associated with OE-style service work, and the M342 is built to meet production-level expectations for fit and function.

What It Helps Address

• Low or unstable engine oil pressure
• Reduced oil circulation from pump wear
• Noisy operation caused by inefficient oil delivery
• Service replacement for stock engine lubrication systems
• Pressure loss related to worn internal pump components

Installation Notes and Tips

Verify engine application, pump drive type, and mounting pattern before installation. This pump uses a crankshaft drive and a four-hole mounting pattern, with gasket or seal included. Confirm pickup tube and screen dimensions against the original setup, and prime the oiling system during installation to support proper initial operation.

Quality Assurance

Melling manufactures this oil pump in the USA and individually tests each unit for pressure and flow. The pump is assembled to production standards using high-quality materials and is designed for dependable service in the listed applications.
