How do you locate cummins engine number?

Answer 1

In general, Cummins engine serial numbers consist of eight (8) digits, e.g. 79012323.

If you have a hard copy of an Owners Manual or an Operation and Maintenance Manual or if you already have access to the online manuals, there is a procedure that describes how to find the engine serial number on your engine's dataplate. These steps will show you how to find that procedure and locate your engine serial number.

When using a hard copy manual go to the section titled "Engine Identification". This will show you where to find your engine serial number.

When using an online manual, follow these steps:

1. Click on "Engine Family Search" link in the left column of QuickServe Online.

2. Select your engine family from the drop down menu.

o Note: If you are not sure which engine family to select, call 1-800-DIESELS, and they can help you determine the correct engine family for your engine.

3. Click "Search". It is not required that you select a Fuel System, Application or Build Year.

4. Click on the "Service" tab located across the top of the page.

5. Click on "Owners Manual" or "Operation and Maintenance Manual."

6. Select the appropriate manual.

7. Open the section titled "Engine Identification". This will show you where to find your engine serial number.

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
