original 20R-0055 Diesel Fuel Injector Assembly for 3176C C11 C13 Engine Excavator Truck Injection Valve Replacement OEM 212-3464 348-4090 original new injector

Engineered as a direct replacement solution for heavy-duty diesel powertrains, the 20R-0055 Fuel Injector Assembly delivers reliable, high-pressure fuel delivery for C12, C12 ACERT, Industrial C12, C10, and 3176C engine platforms. This injector supports critical duty cycles across motor graders, wheel loaders, track type tractors, compactors, pipelayers, diesel generator sets, and marine propulsion systems. Verified cross-references include 317-5278, 10R-1264, 208-9160, 170-5240, and CA20R0055, giving procurement teams flexible sourcing across global aftermarket channels.

Built using precision manufacturing with micron-level tolerances, the 20R-0055 injector body and nozzle assembly are optimized for high-pressure performance under severe operating conditions. Premium metallurgy provides resistance against corrosion, cavitation, thermal fatigue, and fuel contamination, extending service life in construction, mining, oil and gas, and power generation environments. The operating cycle progresses through fuel pressurization, needle valve activation, fuel atomization, combustion optimization, and emission reduction—minimizing black smoke, carbon buildup, cylinder wear, and fuel consumption while improving overall thermal efficiency.

For consistent field results, follow the recommended installation checklist: clean the injector bore, replace the sealing washer, inspect the fuel return line, verify fuel pressure, prime the fuel system, confirm engine startup, and check for leaks. Manufactured to OEM performance standards, the 20R-0055 Fuel Injector is a dependable component for fleet operators, remanufacturers, industrial distributors, and OEM service partners worldwide.
