original C4.4 C6.4 C6.6 Fuel Injector 320-0677 10R-7671 2645A746 for Spares Excavator Accessories diesel Injector Pump original new injector

Engineered for demanding industrial diesel applications, the 10R-7671 Fuel Injector is a precision-manufactured common rail component built to deliver reliable performance across C6, C6.4, and C6.6 engine platforms. Cross-referenced with authorized numbers 10R-7671, 326-4700, 2645A751, and 10R7671R, this injector serves as a direct OEM aftermarket replacement for excavators, wheel loaders, backhoe loaders, motor graders, generator sets, and marine propulsion systems operating in construction, mining, agricultural, and oil & gas environments.

The injector features a precision-machined nozzle assembly with multi-hole injection technology for advanced fuel atomization, ensuring optimized combustion efficiency and reduced emissions. Constructed from high-strength alloy steel, it withstands operating pressures up to 1800+ Bar while maintaining corrosion resistance and long service life. Electronic control compatibility ensures accurate fuel delivery timing, supporting stable idle, responsive throttle performance, and consistent power output under continuous-duty industrial loads. Each unit is manufactured to OEM fitment tolerances for seamless installation on standby, prime, and continuous power generation systems.

Common failure indicators such as hard starting, black or white exhaust smoke, rough idle, reduced power, elevated fuel consumption, or diagnostic fault codes signal replacement needs. For optimal service life, use clean diesel fuel, replace fuel filters regularly, drain water separators, and monitor fuel pressure. During installation, always fit new sealing washers, keep the injector tip contamination-free, follow torque specifications, and verify ECM calibration and fuel return flow after fitting.
