original 10R-7225 Fuel Injector Pump for E320D E324D E325D E329D E330D Excavator Accessories C7 C9 new injector original new injector

The 10R-7225 fuel injector is an original OEM-specification component engineered specifically for the C7 diesel engine platform, including the C7 ACERT variant. Designed as a direct-fit replacement, it matches authorized cross references 2490713, 3282574, and 3879433, ensuring seamless integration with existing fuel system calibration parameters. The injector utilizes precision-machined nozzles manufactured from high-strength alloy steel, delivering consistent atomization and high-pressure fuel delivery across the full operating range of the C7 power unit.

Built around an Electronic Unit Injector (EUI) architecture, this injector provides OEM-calibrated flow rates that support stable cold-start performance, faster throttle response, and increased horsepower output. Its heavy-duty internal structure and corrosion-resistant construction are validated for the demanding duty cycles found in excavators, wheel loaders, motor graders, on-highway trucks, generator sets, industrial power units, and marine applications. Operators benefit from improved fuel economy, reduced black smoke, lower exhaust emissions, and enhanced overall engine durability under continuous load conditions.

For optimal service life and failure-rate performance, the 10R-7225 injector should be installed using high-quality clean diesel fuel, with sealing washers and O-rings replaced during installation, OEM torque specifications followed, and the fuel system primed afterward. Routine preventive maintenance—including regular fuel filter replacement, electrical connector inspection, and ECM diagnostics—helps maintain injector balance rates and long-term reliability. This component serves construction, mining, transportation, power generation, agricultural, marine, oil and gas, and heavy-duty logistics fleets requiring dependable C7 engine performance.
