The DENSO 295050-0720 is an original-type common rail diesel fuel injector engineered for the KOMATSU SAA6D125 engine, carrying authorized OE references 295050-0720, 6252-11-3100, 6252-11-3101, R6252-11-3100 and 295050-2750. It belongs to the KOMATSU 2 injector series and the DENSO Generation 3 product family, featuring stud terminals, a side fuel import location and an 8.92 inch body length. The solenoid actuator is controlled by the engine ECU, which manages injection timing, injection duration, injection quantity and injector response based on engine speed, engine load, rail pressure, boost pressure, coolant temperature, fuel temperature and emission strategy. ECU coding is required during installation.

This high-pressure electronically controlled injector is designed for KOMATSU heavy equipment including the PC400-10 excavator, PC490LC-10 excavator, HM300-3 articulated dump truck and WA470-7 wheel loader. It is suitable for excavator repair, wheel loader service, articulated dump truck repair, construction machinery service, mining and quarry fleet maintenance, SAA6D125 engine rebuilding, diesel fuel system workshops, diesel parts wholesale and global aftermarket export. The solenoid precisely opens and closes the injector to deliver fine atomized spray into the combustion chamber for accurate fuel metering.

Service life depends on clean diesel fuel, correct filtration, water separation and professional installation. Water, rust, dust and poor-quality diesel can damage the nozzle, solenoid control valve and internal precision parts. Before installation, confirm the old injector body number, KOMATSU OE number, engine model, engine serial number and machine serial number. The injector bore must be clean, required seals replaced, the high-pressure pipe inspected and the fuel system bled. After installation, use diagnostic equipment to check injector code, rail pressure, return flow, cylinder balance and ECU fault codes.
