just wondering if there is a way to find the serial number on a cummins engine if the serial number on the engine has dissapeared? Can you cross reference it with any other part off the engine to find the number?

Thanks.

I dont know if this info will help or not. But I'm perty sure besides the data plate there should be a s# stamped in the block itself in case the plate is missing.

If you do not have access to a manual the following instructions tell you where to physically find the ESN on the engine. This will vary based on the engine model. Please note that if your engine dataplate is missing or is not readable, the ESN is identified on the engine block.
ISM:
The dataplate is located on the fuel pump side of the engine, on the rocker housing. The following information is shown on the dataplate:
  • Engine Serial Number (ESN)
  • Critical Parts List (CPL)
  • Model
  • Horsepower and RPM rating
  • Emission statement (if applicable)
ISX:
The engine dataplate, located on top of the rocker lever cover, provides the model identification and other important data about the engine.
  • Engine Serial Number (ESN)
  • Critical Parts List (CPL)
  • Model
  • Advertised horsepower and RPM
ISB:
The dataplate is typically located on the engine rocker cover, but may be located on the side of the gear housing. The engine serial number and CPL provide data for ordering parts and service. NOTE: ISB engines are produced worldwide. The data plates used on engines may differ in appearance and location of information.
NOTE: If the engine dataplate is not readable, the engine serial number can be identified on the engine block on top of the lubricating oil cooler housing. Additional engine information is available by reading the ECM dataplate.
ISC and ISL:
The dataplate is located on the top side of the gear housing. It includes the following engine data:
  • Engine Serial Number (ESN)
  • Critical Parts List (CPL)
  • Model
  • Horsepower and RPM rating
If the engine dataplate is not readable, the ESN can be found on the engine block on top of the lubricating oil cooler housing. Additional engine information is on the electronic control module (ECM) dataplate.​
QSK45 and QSK60:
The dataplate on the QSK45 and QSK60 engines is located at the rear of the engine block opposite the starter. It includes the following data:
  • Engine Serial Number (ESN)
  • Critical Parts List (CPL)
  • Horsepower
  • RPM
