The DENSO common rail fuel injector 095000-6120 is an OE-type replacement component engineered for KOMATSU heavy-duty diesel platforms, including the SAA6D140E, SAA6D140E-5, and 6D140 engines. It is fully cross-referenced with KOMATSU part number 6261-11-3100, as well as R6261-11-3100 and 6261-11-3100C, ensuring direct fitment on PC600-8, PC700-8, WA500-6, HM400-2, and HM350-2 equipment operating in excavation, loading, hauling, mining, and construction environments.

Built around high-pressure common rail electronically controlled injection technology, this injector supports accurate fuel metering, fine atomization, and stable combustion to restore engine power, throttle response, and fuel economy while controlling smoke output. It is designed to withstand the hydraulic load demands and continuous duty cycles of KOMATSU 5 Series machinery, delivering consistent injection performance across varying working conditions.

Before installation, verify the injector number 095000-6120, KOMATSU OE 6261-11-3100, engine model, machine model, and ECU requirements. Clean the injector bore and seat, replace copper washers, O-rings, and seals, and inspect the high-pressure pipe, return line, fuel filter, and common rail cleanliness. Use clean diesel, service fuel filters regularly, drain the water separator, and after installation bleed the system, check for leaks, monitor rail pressure, and perform injector calibration or ECU registration when required. Common fault symptoms such as hard starting, black or white smoke, rough idle, power loss, excessive return fuel, and rail pressure fluctuation can be diagnosed through return-flow testing, cylinder-balance analysis, and common rail injector bench testing.
