Engineered for demanding industrial workloads, the 20R-0759 diesel fuel injector delivers reliable high-pressure fuel delivery for 3412 series engines. Manufactured from high-grade corrosion-resistant steel and machined to tight tolerances, this injector carries the primary OE reference 7W-7118 and cross references 331-9752, 3319752, 7W7118, 20R0759, and 20R-0759, providing broad interchangeability across remanufactured and original equipment supply chains. Its multi-hole high-pressure nozzle operates at 2000–2200 bar typical, with a 150°–160° spray angle optimized for complete atomization and efficient combustion.

The 3412 platform powers a wide range of heavy equipment, including the 777D Dump Truck, 3512 Generator, D11T Bulldozer, 992K Wheel Loader, and 3512B Industrial Pump. Beyond earthmoving and mining fleets, this injector supports marine engines, industrial generators, and pumping stations where uptime and fuel efficiency are critical. Precision machining and OEM-certified specifications ensure reduced particulate emissions, stable idle performance, and consistent power output across the full duty cycle, making it a preferred choice for construction, mining, and remanufactured parts service centers worldwide.

Installation requires 25–35 Nm torque using a calibrated wrench, with a clean injector seat, prepared fuel line, and light oil lubrication on threads. Inspect the nozzle every 500 operating hours and diagnose faults by checking spray pattern, fuel pressure, leakage, and opening delay to maximize service life.
