Frequently asked questions

What Komatsu machines do you cover?

We index parts for Komatsu PC-series excavators, WA-series wheel loaders, D-series dozers, and HM articulated trucks. Start with the OEM part number, or open a model page such as Komatsu PC200 / PC300.

Are these genuine Komatsu parts?

Listings are aftermarket replacements cross-referenced to Komatsu OEM numbers. Compare the stamped number, connector, and mounting points with your old part.

How do I find a Komatsu part by number?

Enter the OEM number in site search or open /parts/{number} when a dedicated cross-reference page exists. Avoid generic category pages if you already have the exact number.
