Engine-specific replacement injector for 3412 series |
The 3412 Diesel Fuel Injector 173-9379 is specifically engineered to match the precise fuel delivery requirements of the 3412, 3412C, and 3412B engines. As a 12-cylinder V-type diesel powerplant used across heavy industrial machinery, the 3412 series demands injectors that deliver consistent atomization and accurate metering. This injector is built to strict OEM specifications under OE number 7W-3379, with verified cross references 326-2150, 7W3379, CAT173-9379, and 1739379, ensuring straightforward drop-in replacement for service operations and engine rebuilds.
Manufactured with a high-pressure steel body, the unit resists wear, corrosion, and thermal fatigue, supporting continuous operation in extreme temperature environments. It is rigorously OEM and aftermarket tested to provide reliable fuel atomization, efficient combustion, and stable engine performance under heavy load conditions. Suitable for continuous operation, it helps reduce fuel consumption and lower emissions while maintaining the power output expected from 3412 engines.
This injector is widely applied across excavators, bulldozers, loaders, generators, marine engines, mining trucks, industrial pumps, drilling rigs, large tractors, and harvesters. For optimal service life, inspect the injector every 500 hours of operation, keep fuel filters and lines clean, replace worn seals and gaskets, use -approved lubricants and fuels, and store spare injectors in a dry, temperature-controlled environment. Common symptoms of injector failure on 3412 engines include misfire, excessive smoke, high fuel consumption, rough idle, and low power; these can be resolved by cleaning or replacing the injector, checking the nozzle, replacing seals, inspecting wiring, or recalibrating the spray pattern.
