Engineered for demanding heavy-duty diesel platforms, the 386-1771 Fuel Injector Assembly delivers reliable, high-pressure fuel atomization for the 3512B V12 turbocharged aftercooled engine. Manufactured from high-strength alloy steel with a precision-machined nozzle and hardened body, this electronic unit injector meets OEM dimensional accuracy for direct drop-in replacement. Each unit is flow tested and leak tested to ensure uniform spray pattern, balanced injection, and long service life across prime, continuous, and emergency-duty operating cycles.
Cross-referenced to 3861771, OE3861771, OEM3861771, 20R-1280, 246-1854, 392-2000, 10R1278, 20R-1265, and 20R-3477, this injector supports a wide range of 3512B industrial, generator, and marine configurations. Typical applications include data center and hospital backup power systems, offshore vessel propulsion, tug boats, cargo auxiliary engines, mine power modules, haul truck drivetrains, drilling and crushing power units, offshore platforms, land pumping units, and gas compression engines used in global industrial power plants.
Recommended maintenance includes approved diesel fuel and filtration, periodic flow-rate testing, seal inspection, and injector balance verification. During installation, ensure fuel system cleanliness, inspect the injector bore, fit new seals and O-rings, follow torque specifications, perform a leak test, and complete ECM calibration for optimum performance, low emissions, and reduced fuel consumption.
