original 194-5080 Diesel Engine Fuel Injector for Excavator 345B C10 C12 Replacement 137-2500 116-5425 161-1708 212-3460 10R-0960 new injector original new injector

Engineered exclusively for the C12 diesel platform, the 194-5080 fuel injector delivers factory-calibrated fuel delivery and atomization that matches original engine performance specifications. Built with high-strength alloy steel and precision-machined nozzle components, this injector withstands the high-pressure demands of C12 Truck, Industrial, Marine, Generator, and Power Unit engines operating under continuous heavy-load conditions. Each unit is calibrated to OEM-standard flow rates, ensuring stable injection pressure, controlled spray patterns, and consistent combustion across the full engine operating range.

The 194-5080 injector is a direct replacement for C12 applications and is fully interchangeable with part numbers 10R0957 and 0R8479. Its electronic unit injection design supports precise fuel metering for improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions. The assembly is suitable for on-road trucks, off-road construction and mining equipment, marine propulsion systems, and stationary generator sets, maintaining reliable engine performance in both mobile and stationary installations.

Routine maintenance includes using clean diesel fuel, replacing fuel filters at recommended intervals, preventing water contamination, monitoring fuel pressure, and conducting periodic diagnostic inspections. During installation, operators should disconnect battery power, relieve fuel system pressure, clean the mounting area, inspect the injector bore, replace O-rings and sealing washers, torque to OEM specifications, bleed the fuel system, and verify operation through diagnostic testing. Each injector is factory-tested and backed by a 12-month warranty.
