Electronic engine controller module identified by Komatsu reference 7835-26-1003. Komatsu's parts search identifies the exact number as CONTROLLER, while exact-number application records publish PC200-7, PC210-7, PC220-7 and PC270-7 excavators. Five exact owned photographs show the same finned aluminium enclosure, three keyed connector blocks, mounting holes and identification label. The compact form 7835261003 is only a search alias. Numbers 7835-26-1004 through -1009 are related controller-family references and are not presented as direct interchanges because Komatsu lists them as separate parts. Confirm the complete label, connector keys, software/calibration, engine controller position and serial.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
