BCBC S1310 Engine Oil Pump Sprocket

Engine Oil Pump Sprocket Overview

The Melling S1310 engine oil pump sprocket is a stock replacement component for applications that require a new sprocket during oil pump service. It is built from steel and matches the tooth count and dimensions needed for proper oil pump drive operation.

Key Features

• Steel construction for oil pump drive service
• 31-tooth design for the specified application
• 0.5 in. inside diameter and 2.5 in. outside diameter
• 0.325 in. thickness for dimensional match-up
• Stock replacement part for Melling oil pump service

Detailed Description

The Melling S1310 is intended to complete an oil pump replacement when the original sprocket shows wear, fatigue, cracking, or twisting damage. Even when the old part looks serviceable, internal stress can affect drive reliability, so replacing the sprocket during pump service helps restore the correct mechanical interface. This part cross-references Monroe Shocks & Struts (e.g., 7B0 115 121, 5184273AD) for the same application. Use the Melling S1310 when servicing compatible Chrysler 300, Dodge Charger, Jeep Grand Cherokee, and Ram 1500 applications that call for this stock oil pump sprocket.

What It Is Used For

• Replacing a worn or damaged oil pump drive sprocket
• Addressing cracking or metal fatigue in the original sprocket
• Restoring proper oil pump drive engagement
• Completing an oil pump service with the correct matching component

Installation Notes and Tips

Verify tooth count, inside diameter, outside diameter, and thickness before installation. Confirm the application against the vehicle service information for Chrysler 300, Dodge Challenger, Dodge Charger, Jeep Cherokee, and Ram 1500 fitments listed for the Melling S1310. Replace the sprocket whenever the oil pump is being serviced and the original part shows signs of wear or distortion.

Quality Assurance

Melling recommends replacing the sprocket as part of a complete oil pump installation when required, based on the risk of fatigue-related damage in the original component. The S1310 is a stock replacement part engineered to match the specified oil pump drive application.
