Engineered for severe-duty diesel platforms, the 0R-8786 fuel injector delivers precision-controlled fuel metering for the 3412, 3412B and 3412C engine series. This remanufactured mechanical injector assembly is built to OEM-level specifications, incorporating optimized nozzle geometry and precision atomization to promote complete combustion, stable idle quality and balanced cylinder operation across the full load range. Cross-referenced with 4P9830 and 8N7005, it provides direct interchangeability for maintenance operations and inventory consolidation.
Constructed from high-strength alloy materials with industrial-grade sealing, the 0R-8786 injector is designed for continuous-duty operation in demanding environments. Corrosion-resistant surface treatments make the assembly suitable for marine propulsion in fishing vessels, tugboats and offshore support vessels, while its heavy-duty architecture supports prime power generation, emergency backup generators, data center power, mining haul trucks, drilling equipment, fracturing units, well service pumps, compressor drives and stationary industrial engines. Extended service intervals reduce total cost of ownership across the operating fleet.
Proper installation requires verified injector bore cleanliness, new sealing washers, correct service-manual torque values, and complete fuel system bleeding before startup. Routine maintenance—including fuel filter replacement, water separator draining and periodic injector balance testing—preserves performance and helps prevent hard starting, rough idle, black or white exhaust smoke, engine vibration and elevated fuel consumption throughout the injector service life.
