original 7E-3384 Diesel Engine Fuel Injector Assembly for 3500A 3508 3512 3516 Common Rail Injector 7E-3382 0R-2921 10R3053 Replacement original new injector

Engineered as a direct OEM-grade replacement for the 3512A V12 diesel engine platform, the 7E-3384 Fuel Injector Assembly delivers precision-controlled fuel atomization for demanding continuous-duty applications. Cross-referenced with 0R-8479, this mechanical unit injector is machined from high-strength alloy steel and calibrated to strict OEM flow tolerances, ensuring consistent injection pressure, uniform spray pattern, and reliable ignition performance across the full load range of 3500 Series power units.

Designed for installation in the cylinder head of the 3512A engine, this injector supports heavy-duty operation in diesel generator sets, marine propulsion and auxiliary systems, mining haul equipment, oil and gas drilling rigs, fracturing units, compressor stations, and industrial power plants. Corrosion-resistant construction and precision-lapped internal components extend service life under high-vibration, high-temperature environments. Engineering benefits include improved combustion efficiency, reduced fuel consumption, lower exhaust smoke, stable power delivery, and extended engine lifespan—making the 7E-3384 a preferred choice for utility power plants, data center backup systems, offshore vessels, and continuous-process industrial facilities.

Installation requires new sealing washers, clean fuel lines, and proper torque values following OEM procedures. Recommended maintenance includes use of clean diesel fuel, regular fuel filter replacement, water contamination prevention, and periodic injector bench testing. Diagnostic support covers fuel pressure analysis, cylinder balance testing, nozzle spray inspection, and leak-down testing for reliable long-term performance.
