Caterpillar original Caterpillar 267-3361 Diesel Engine Fuel Injector for C9 Engine Excavator new injector original new injector

The Caterpillar 267-3361 fuel injector is engineered as a direct OEM replacement for C9 and C9.3 diesel engine platforms. Built with precision-machined nozzle assemblies and wear-resistant internal components, this injector delivers consistent high-pressure fuel atomization across demanding industrial duty cycles. It carries cross reference compatibility with 10R-7675, 328-2574, 387-9433, and 295-1407, ensuring broad interchangeability across the C9 engine family used in excavators, wheel loaders, articulated trucks, and generator sets.

Featuring OEM calibrated flow rates, stable injection pressure, and a corrosion-resistant coating, the 267-3361 injector supports precise fuel metering, improved combustion efficiency, and reduced fuel consumption. Enhanced engine power output and lower emissions are achieved through high-temperature resistance and consistent fuel delivery, extending both engine life and service intervals. Each unit is manufactured to OEM-standard tolerances using industrial-grade materials designed for long operational lifespan in harsh operating environments.

The injector is suited for construction, mining, industrial power, power generation, and marine auxiliary applications. Proper maintenance includes the use of clean diesel fuel, regular fuel filter replacement, avoidance of contaminated fuel, and periodic diagnostic testing such as ECM fault code analysis, injector return flow testing, fuel pressure inspection, cylinder balance testing, and injector electrical resistance testing to ensure sustained performance and reduced operating costs.
