original Fuel Injector 116-5414 for C12 Diesel Engine 1165414 Common Rail Injector Assembly 10R-0725 10R-0967 Replacement for OEM Cummins Engine Parts original new injector

Engineered for demanding heavy-duty diesel applications, the 116-5414 Fuel Injector serves as a direct replacement component for C12, C12 ATAAC, C10, 3176B, and 3196 diesel engines. Manufactured from high-strength alloy steel and factory-tested for reliability, this Electronic Unit Injector (EUI) is cross-referenced with alternative part numbers 0R-8479 and 10R-0957, allowing straightforward sourcing across global fleet operations. Its precision-machined nozzle assembly delivers accurate fuel metering, high-pressure atomization, and consistent spray patterns essential for optimized combustion performance.

Installed at the cylinder head, the injector operates via ECM-controlled solenoid activation: fuel enters the injector body, the high-pressure chamber pressurizes the diesel, and atomized fuel is delivered directly into the combustion chamber. This precise delivery process enhances horsepower output, lowers fuel consumption, reduces smoke emissions, and improves cold-start performance. The injector is compatible with excavators, wheel loaders, articulated dump trucks, generator sets, marine propulsion systems, industrial power units, mining equipment, and on-highway diesel trucks, supporting operations across construction, mining, marine, agriculture, energy, and power generation sectors.

Built to withstand high-pressure fuel handling with corrosion-resistant construction, the 116-5414 injector ensures a long operational lifespan under continuous industrial workloads. Installation requires replacement of sealing washers, correct torque per service manual, and clean diesel fuel to prevent contamination. Backed by a 12-month warranty and export standard packaging, this component is an ideal solution for B2B distributors, workshops, and OEM aftermarket suppliers.
