What Numbers Do I Need to Order Parts for My Yanmar?
Yanmar engines are found in a huge variety of applications, including agriculture applications, industrial applications, and marine applications. This product range might make it difficult to locate your engine numbers, as there isn’t much consistency in location across applications.
With a lot of other engine types, you’ll hear us asking for the engine serial number. For Yanmar, though, we actually get the most information from your engine model number.
This number helps us ensure you’re getting parts that fit your specific engine—each engine model needs specific parts. Not every part will fit every Yanmar engine.
To avoid unnecessary returns and downtime, it’s important to make sure you’re ordering the right parts the first time. That’s why knowing the engine model number is so important.
It’s also possible that you can use the same part number as the parts you’re replacing. But if you want to be really certain everything will fit right, it’s best to find your engine model number. We’ll likely ask for it, and it’s worth the time to find.
