Engineered to meet Caterpillar OEM replacement specifications, the 20R-0055 Fuel Injector Assembly is a precision-built high-pressure diesel injection component designed for the CAT C12 engine platform and related heavy-duty diesel applications. Manufactured with micron-level tolerances, this injector delivers accurate fuel metering and fine atomization, directly supporting combustion efficiency, stable power output, improved fuel economy, and reduced emissions across severe duty cycles.
This injector serves as a current replacement for multiple historical Caterpillar part numbers, including injector group 317-5278, Reman number 10R-1264, and former numbers 208-9160 and 170-5240, with industry references CA20R0055 and CAT20R0055. It is compatible with CAT C12, C12 ACERT, Industrial C12, C10, and 3176C engine families, covering both industrial and marine diesel engines. Typical equipment applications include motor graders, wheel loaders, track-type tractors, compactors, and pipelayers, as well as construction, mining, oilfield, power generation, and stationary industrial installations.
In operation, the injector receives high-pressure diesel fuel from the injection system, lifts the needle valve according to pressure and injection timing requirements, and atomizes fuel through micron-sized nozzle holes for efficient air-fuel mixing. This controlled combustion process helps reduce black smoke, fuel consumption, carbon buildup, and cylinder wear. Premium metallurgy provides superior resistance to corrosion, cavitation, thermal fatigue, and fuel contamination, ensuring long service life for fleet maintenance, engine rebuild, and heavy equipment repair operations.
