Engineered for demanding heavy-duty operation, the 173-9379 Fuel Injector delivers precise fuel atomization and reliable high-pressure performance for 3412, 3412C, and 3412B diesel engines. Manufactured from high-strength hardened steel with a corrosion-resistant surface, this injector is designed to withstand continuous operation in extreme environments ranging from -40°C to 120°C. Cross-referenced with OE numbers 7W-3379, 1739379, 326-2150, 7W3379, and CAT173-9379, it offers a direct fit replacement for original units in a wide range of 12-cylinder V diesel platforms.
Operating within a 1500–2000 bar pressure range, the injector optimizes combustion efficiency, reducing fuel consumption and emissions while maintaining stable idle and full-load performance. It is widely applied across construction machinery such as excavators, bulldozers, and loaders, as well as mining trucks, marine diesel engines for offshore and shipping applications, industrial generators and pumps, large agricultural tractors and harvesters, and oil & gas drilling rigs. Each unit is OEM and aftermarket tested to ensure reliable service life and consistent injection performance.
Routine inspection every 500 operating hours, clean fuel filters, and manufacturer-specified torque during installation are recommended to maximize service life. Common symptoms such as misfire, smoke, rough idle, or low power can be resolved by cleaning or replacing the injector, checking the nozzle spray pattern, replacing seals, and calibrating the unit. Backed by a 12-month warranty.
