Caterpillar original Caterpillar 10R-2828 diesel fuel injector replacement for C7 C9 engine common rail new injector original new injector

The Caterpillar C9 fuel injector 10R-2828 is a precision-engineered electronic unit injector designed for OEM-level replacement in CAT C9 and C9 ACERT diesel engines. Built to match factory fuel flow specifications, it features precision-ground internal components, high-temperature resistant materials, and anti-corrosion coatings that ensure reliable operation under severe-duty industrial, mining, marine, and construction environments. The injector delivers highly accurate fuel metering controlled by the engine ECM, based on engine load, speed, intake pressure, coolant temperature, and fuel demand.

This unit optimizes spray pattern atomization for superior combustion efficiency, lower emissions, and improved fuel economy while maintaining consistent power output across demanding duty cycles. Each injector is factory-tested to verify performance consistency, injector response, and sealing integrity, helping reduce downtime and extend service life. It serves as a direct replacement for part numbers 249-0713, 328-2574, and 10R-2828R, fitting CAT 330D and 336D excavators, wheel loaders, motor graders, generator sets, marine engines, and oilfield equipment.

Proper installation practices support long-term reliability: clean the injector bore thoroughly, replace all sealing components, inspect fuel lines and injector wiring, apply OEM torque values, bleed air from the fuel system, verify injector coding if required, and perform ECM diagnostics after installation. Routine maintenance using high-quality diesel fuel, regular filter replacement, fuel cleanliness monitoring, and periodic pressure checks will further extend injector lifespan. This C9-series fuel injector offers a dependable solution for B2B buyers seeking durable, efficient diesel injection performance in heavy-duty Caterpillar-powered machinery.
