original 116-5414 Diesel Fuel Injector C12 116-8899 128-8510 147-0373 170-5240 new injector original new injector

The 116-5414 fuel injector is engineered as a direct replacement component specifically calibrated for C12 and C12 ATAAC diesel engines, as well as C10, 3176B, and 3196 engine platforms. Manufactured to OEM performance standards, each injector assembly is factory-tested for flow rate, spray pattern, and sealing integrity, ensuring reliable fuel metering across high-load operating conditions found in construction machinery, mining equipment, marine propulsion systems, and on-highway diesel trucks.

Constructed from high-strength alloy steel with precision-ground nozzle components, the 116-5414 injector delivers accurate fuel atomization, improved combustion efficiency, enhanced horsepower output, and reduced smoke emissions. Advanced calibration technology supports better cold-start performance and lower fuel consumption, while the corrosion-resistant design withstands long operational service cycles in harsh industrial environments including power generation sets, wheel loaders, articulated dump trucks, excavators, and industrial power units.

During installation, technicians should always replace sealing washers, follow service manual torque specifications, keep injector tips contamination-free, and use clean diesel fuel to prevent internal leakage or nozzle damage. Cross-referenced with 0R-8479, 10R-0957, and 3176B part numbers, this injector supports a wide range of heavy-duty applications. Regular fuel filter replacement and monitoring of fuel pressure are recommended to maintain consistent injection performance and extend component lifespan.
