original 295050-0401 Common Rail Injector Replacement 370-7280 370-7281 370-7282 370-8276 for C4.4 C6.6 C7.1 Excavator original new injector

The DENSO 295050-0401 common rail fuel injector is specifically engineered for C4.4, C6.6, and C7.1 diesel engines, delivering precise fuel atomization and reliable injection pressure for demanding industrial operations. This injector is a direct-fit replacement matching OEM calibration values, ensuring optimal combustion efficiency, reduced emissions, and consistent engine performance across excavator, generator, loader, construction, and agricultural equipment applications including the 320E and 323E excavator models.

Manufactured to original equipment specifications with cross-reference compatibility for 370-7282 and 20R-2478, the injector assembly undergoes strict dimensional verification, flow rate testing, and nozzle spray pattern inspection to guarantee dependable performance in common rail fuel injection systems operating under heavy-duty load conditions.

Before installation, verify the OE number 295050-0401 and engine serial number, then replace the injector seal kit, inspect fuel rail pressure, and install a new fuel filter. During installation, clean the injector bore, apply OEM torque specification, fit a new copper washer, and confirm the electrical connector lock. After installation, bleed the fuel system, clear ECU fault codes, perform injector coding, complete idle calibration, and conduct a leak test to ensure proper engine integration.
