Collection: Replacement Parts Compatible with KOMATSU

Browse compatible replacement parts for Komatsu excavators, wheel loaders, dozers and other construction machinery. This collection groups engine, hydraulic, cooling, travel, electrical and operator-control components so maintenance teams can narrow a search by the component already installed. Listings vary by machine configuration and production period, so use the product page as the source for included parts and stated applications.

Machine serial prefixes and component assembly numbers are useful for distinguishing travel, hydraulic and engine options within a series.

• Match the installed part number and any listed cross-reference.
• Confirm the complete equipment model, engine or transmission code, and serial range.
• Compare dimensions, connectors, mounting points, voltage and other listing-specific details.

Fitment FAQ: Does a listing marked compatible with Komatsu fit every machine from that brand? No. Compatibility applies only to the part numbers, models and specifications stated on the individual product page. If details are uncertain, compare the old component and contact Stellar Spares before ordering. Brand names and part numbers are used only for compatibility reference; Stellar Spares is not affiliated with or endorsed by Komatsu.
