original 0R-3419 Diesel Fuel Injector Pencil Nozzle for 3204 3400 Engine Common Rail Fuel Pump 4W7015 4W-7018 0R-1742 Replacement original new injector

Engineered as a direct replacement for the 0R-3419 fuel injection nozzle assembly, this remanufactured component delivers OEM-level performance for the 3204 four-cylinder industrial diesel engine platform. Each unit is built to meet original specifications for opening pressure, spray angle, and atomization geometry, ensuring stable combustion characteristics across naturally aspirated, turbocharged, generator set, and marine configurations. The assembly cross-references with 4W-7015, 1W-3995, 8N-7004, 1W-1354, 1W-4105, 2W-4387, and 7W-7015, providing broad interchangeability for global aftermarket service.

Manufactured from heat-treated alloy steel with a wear-resistant needle and seat design, the nozzle features micron-level orifice machining and a corrosion-resistant surface treatment. The optimized spray pattern promotes uniform fuel atomization, reduces carbon buildup, and improves fuel economy while enhancing throttle response. Heavy-duty construction ensures reliable operation under high-temperature and high-load conditions found in construction, mining, forestry, marine propulsion, and stationary power generation applications. The unit is also fully compatible with professional Reman programs and diesel injector rebuild processes.

For maximum service life, operate the engine on clean diesel fuel with OEM-grade filtration and inspect injectors every 2,000–3,000 hours for carbon deposits, leakage, and irregular spray. Verify opening pressure on a calibrated test bench, lubricate seals with clean fuel during installation, torque to specification, and bleed the fuel system before startup.
