Introduction
Cummins engines power a wide variety of heavy equipment and vehicles, making correct identification essential for maintenance, repairs, and ordering parts. Knowing how to read and interpret Cummins engine identification numbers helps operators and technicians ensure compatibility and proper service.
Where to Find Cummins Engine Identification

• Cummins engine identification numbers are typically found on the engine’s data plate or stamped on the engine block.
  
• The data plate includes key information such as engine serial number, model number, and sometimes the arrangement number.
  
• On some engines, the serial number may also be found on the valve cover or near the fuel injection pump.
  

Components of Cummins Engine ID

• Serial Number: A unique number assigned to each engine, used to track manufacturing details and history.
  
• Model Number: Identifies the specific engine design and configuration (e.g., 6BT, ISX).
  
• Arrangement Number: Defines the exact components and options fitted to the engine, such as turbochargers or emissions equipment.
  
• Engine Family: Used primarily for emissions certification and regulatory compliance.
  

Using the Engine ID for Parts and Service

• When ordering parts, providing the full engine serial and arrangement numbers ensures correct matches.
  
• Service manuals and diagnostic tools often require the engine ID to access accurate specifications and procedures.
  
• Dealers and Cummins service centers rely on engine identification to provide tailored support.
  

Tips for Accurate Identification

• Clean the area around the data plate or stamped number to read it clearly.
  
• Take photos or write down the numbers for reference.
  
• Cross-check numbers with equipment documentation when possible.
  
• If unsure, contact a Cummins dealer or authorized service provider with the available engine information.
  

Conclusion
Proper identification of Cummins engines is crucial for effective maintenance and repairs. Understanding where to find and how to interpret the engine serial, model, and arrangement numbers helps operators and technicians secure the right parts and support, ensuring optimal engine performance and longevity.
