6150-12-1370 is identified by Komatsu's official engine-parts page as a guide. The owned product archive contains four consistent views of the corresponding cylindrical valve-guide components. Komatsu's public record does not publish a complete engine or machine serial-range application list, so the former broad 6D125 claim is not presented as verified fitment. Confirm the complete number, stem bore, outside diameter, overall length, installation depth and machine serial number.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
