Komatsu Engine Parts Hub
Komatsu Engine Parts should be selected by engine model, part number, repair system, and machine application. This page is the main educational gateway for Komatsu engine parts on 19PARTS. Use it to move from a broad engine search into the correct lower-level system hub, engine-family hub, or product search path before ordering.
How to use this Komatsu engine parts gateway
Start with the repair area if you know the system being serviced. Start with the engine model if you are matching parts to a Komatsu engine family such as S6D125, SAA6D107E, SAA6D125E, S6D155, SA6D140, or SAA6D140E. Always confirm the final part number against the machine serial range, engine arrangement, and any supersession or replacement notes.

Before ordering Komatsu engine parts
Komatsu engines often have multiple versions within the same broad family. A part may change by serial range, arrangement, turbocharged versus naturally aspirated configuration, emissions specification, or machine application. Use this page to choose the correct path, then verify the exact part number before checkout. If you have a part number, search it directly with and without dashes.
Need help? Send us the Komatsu model, machine serial number, engine model, and any part number stamped on the original component. We can help narrow the search before you order.
