However, the dataplate can be hard to find, as it will be in different locations based on the model of the engine. The location of the dataplate for your engine will be in your owner's manual. If you've long since lost the physical owners manual, but can accessCummins Quickserve, you can see a digital copy of the owner's manual there.

Cummins Engine Serial Number Format

Cummins engine serial numbers look more like a classic serial number thanCaterpillar ESNsdo. Cummins ESNs are eight digits long and are composed only of numbers. They go in a numerical sequence, based on which engine came first off the assembly line. There is no special designation for particular models.

Cummins engines do have something a little unique, called a CPL. CPL stands for Critical Parts List and is a list of the critical parts of the engine. There are fewer CPLs than ESNs because multiple engines can have the same CPLs. When ordering most major parts of an engine, providing a CPL will work just as well as supplying an ESN.
