original Fuel Injector 320-2940 Common Rail Diesel Injector for C9 Excavator Engine 10R-7221 10R-7222 10R-7223 Diesel Engine Auto Parts original new injector

Engineered as a direct replacement for the C9 diesel engine platform, the 320-2940 Fuel Injector delivers precise fuel metering and reliable injection performance across demanding industrial applications. Cross-referenced with 3202940 and 10R-7675, this injector assembly is manufactured to OEM calibration standards to ensure seamless integration with C9, C9 ACERT, C9 Industrial, C9 Power Generation, and C9 Marine engine configurations. Each unit is tested to guarantee stable spray patterns, accurate delivery volume, and consistent response under high-pressure common rail operating conditions.

The 320-2940 injector features advanced atomization performance, high temperature resistance, and corrosion protection for extended service life in harsh operating environments. Key performance benefits include improved combustion efficiency, enhanced fuel economy, reduced black smoke emissions, stable engine power output, and faster throttle response. Widely deployed in excavators, wheel loaders, motor graders, generator sets, mining trucks, marine engines, and industrial power units, the injector supports fleet operators across North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia. Equipment compatibility should be verified using the machine serial number and engine arrangement number.

For optimal service life, use high-quality diesel fuel, replace fuel filters regularly, drain water separators, and monitor fuel pressure. During installation, thoroughly clean the injector bore, inspect the cylinder head seating surface, replace sealing components, apply specified torque values, and perform an ECM diagnostic check followed by an engine performance test.
