original 111-3718 Fuel Diesel Injector Pump for 3508 3512 3516 3508C Engine Excavator Loader Common Rail Fuel Injector Assembly OR-8338 224-9090 original new injector

Engineered for demanding heavy-duty diesel platforms, the 111-3718 Fuel Injector Assembly delivers precise fuel metering and reliable high-pressure atomization for the 3500 Series engine family. Manufactured to OEM specifications from alloy steel with corrosion-resistant construction, this injector is factory flow-tested and calibrated to ensure consistent injection performance across all cylinders. Cross-referenced under 0R-8688, 10R-0955, and 20R-2055, it is a direct-fit replacement engineered for maximum operational lifespan under continuous industrial duty cycles.

This injector is fully compatible with 3512A, 3512B, 3516A, 3516B, and 3508B engines used in prime power and standby generator sets, marine propulsion systems, offshore platforms, mining haul trucks, drilling rigs, oilfield compressor packages, and utility power plants. The precision-engineered nozzle system supports high-pressure direct injection, improving combustion efficiency, lowering fuel consumption, enhancing cold-start behavior, and reducing exhaust smoke emissions—critical performance factors for tug boats, data centers, and remote field generators operating under variable loads.

Installation requires thorough cleaning of the injector bore, replacement of sealing washers, inspection of fuel lines, and torque application per service manual specifications, followed by fuel pressure testing and engine performance validation. Symptoms indicating replacement include hard starting, excessive smoke, elevated fuel consumption, rough operation, misfire, or high exhaust temperature. Backed by a 12-month warranty for industrial end users and fleet operators.
