How to Identify Your Komatsu Serial Number (Quick Guide)

- Not sure which Komatsu manual you need?

- Finding your serial number is the key to getting the right workshop manual.

- This quick guide shows you exactly where to look — whether you own an excavator, dozer, or wheel loader.

Here’s how to find it:

🟡 **For Excavators:**  
Look on the metal plate located near the cab base or under the operator seat.  

🟡 **For Bulldozers:**  
Check the front frame or near the right-hand track.  

🟡 **For Wheel Loaders:**  
The plate is usually mounted behind the cab on the left side.

Once you have the serial number, match it with the range shown on your KManuals product page (e.g. S/N 50001 and up).
