Perkins original Perkins 10R-7225 Fuel Injector Pump for C7 C9 Engine E320D E325D E330D Excavator new injector original new injector

The Perkins 10R-7225 fuel injector is engineered as a direct OEM replacement for Perkins C7 diesel engines operating across construction, industrial, marine, and power generation applications. Built with high strength alloy steel and a precision nozzle design, this Electronic Unit Injector delivers consistent high-pressure fuel atomization, ensuring stable combustion and reliable cold-start performance under demanding operating conditions. It replaces the original assembly with OEM-calibrated flow rates that meet strict factory tolerances.

Designed for heavy-duty service, the 10R-7225 injector features a corrosion-resistant internal structure with high thermal stability, significantly extending service life and reducing failure rates in harsh field environments. It directly replaces part numbers 2490713, 3282574, and 3879433, making it a versatile solution for fleet operators, equipment dealers, and maintenance workshops servicing Perkins excavators, wheel loaders, motor graders, on-highway trucks, generator sets, and industrial power units. Routine maintenance such as using clean diesel fuel, replacing fuel filters, and inspecting electrical connectors helps preserve long-term injector performance.

This injector delivers measurable operational benefits including improved fuel economy, faster throttle response, reduced black smoke, lower exhaust emissions, enhanced engine durability, and increased horsepower output. For installation, technicians should prime the fuel system, replace sealing washers and O-rings, follow OEM torque specifications, and perform ECM diagnostics to confirm proper injector balance rates and cylinder performance.
