original 20R-0055 Engine Assembly Components Injector Assembly Fuel Injector for 3176C C11 C13 Excavator Truck new injector original new injector

The 20R-0055 fuel injector is engineered as a direct replacement assembly specifically calibrated for C12, C12 ACERT, C10, and 3176C diesel engine families. Each unit is built to meet replacement specifications, ensuring precise fitment and dependable operation within the original fuel system architecture. The injector body is produced with micron-level tolerances, allowing accurate fuel metering and consistent spray atomization across demanding heavy-duty duty cycles found in construction, mining, marine, power generation, and oil and gas applications.

Through optimized nozzle geometry and high-pressure injection technology, this fuel injector assembly promotes more complete fuel combustion, supporting improved fuel economy and reduced exhaust emissions. The premium metallurgy used in critical wear components delivers strong resistance to corrosion, cavitation, thermal fatigue, and fuel contamination, extending service intervals and lowering total operating cost. Authorized cross references include 317-5278, 10R-1264, 208-9160, 170-5240, and additional part numbers CA20R0055 and CAT20R0055, facilitating straightforward identification and replacement across global equipment inventories.

Prior to installation, technicians should clean the injector bore, install a new sealing washer, inspect the fuel return line, verify fuel pressure, prime the fuel system, confirm clean engine startup, and check all connections for leaks. Following this procedure helps maintain injector performance, protect engine integrity, and ensure long-term reliability of C12 and 3176C powered equipment operating in severe industrial environments.
