Cummins engines are renowned for their durability and adaptability, making them a trusted choice in marine, industrial, and agricultural applications. A crucial identifier for understanding a Cummins engine’s specifications is the CPL number (Control Parts List). This unique code helps owners and technicians accurately order parts, perform maintenance, and troubleshoot efficiently.

In this guide, we’ll explain what a CPL number is, where to find it, how to read it, and why it’s essential for maintaining your Cummins engine.

1. What Is a Cummins CPL Number?

The CPL number is a unique identifier assigned to Cummins engines that share the same configuration. It provides details about the engine’s critical components, such as:

Cylinder heads
Pistons
Camshaft specifications
Turbocharger models
Fuel system components

The CPL number ensures consistency and compatibility when replacing parts or servicing the engine, making it indispensable for accurate maintenance and repair.

2. Where Can You Find the CPL Number on a Cummins Engine?

The CPL number is located on the engine’s dataplate, a rectangular metal plate typically found on:

The side of the engine block
The valve cover
The timing gear cover

Tips for Locating the CPL Number (See Reading Your Cummins Dataplate)

Look for the label “CPL” followed by a series of numbers.
The dataplate often includes other critical information, such as the engine serial number and horsepower rating.

If the dataplate is damaged or missing, refer to engine documentation or consult a Cummins dealer for further assistance.
