Caterpillar original Fuel Injector, Excavator Attachment, 2113025, 10R-7228 for C18 C16 C15 C22 C27 C32, 2959085 Cross Reference, Replacement for OEM 2490709 original new injector

The Caterpillar 10R-7228 is a precision-engineered diesel fuel injection component purpose-built for the Caterpillar C18 engine platform, compatible with all listed C18 variants including industrial, marine, generator, oilfield and power module configurations. As a critical part of the high-pressure diesel fuel system, it delivers precisely metered fuel into combustion chambers and atomizes fuel into fine droplets to support optimal air-fuel mixing, directly contributing to stable combustion efficiency, rated power output, compliant emissions control and reduced fuel consumption for demanding industrial operations.

Manufactured to strict industrial and OEM-equivalent standards, the 10R-7228 injector is engineered to withstand extreme operating conditions including sustained high-load cycles, elevated combustion temperatures, extended service hours and harsh environmental exposure. Its industrial-grade features include precision-machined nozzle assemblies, OEM-standard dimensional accuracy, high-pressure injection capability, excellent wear resistance, stable combustion performance and reduced exhaust smoke, supporting long service life and consistent engine responsiveness.

This injector is widely used across core heavy industry sectors including mining, marine, construction, oil & gas and power generation, with common installations covering diesel generator sets, mining trucks, quarry equipment, crushing plants, drilling rigs, marine vessels, tug boats, water pump systems and industrial compressors. Buyers must verify engine serial number ranges and arrangement codes before ordering; installation must follow official Caterpillar service procedures, with regular fuel filter replacement and periodic injector balance testing recommended to extend service life.
