Perkins original 0R-1745 Diesel Pencil Fuel Injector Nozzle for 3406 3408 3406B 3408B 3408C 3412 3412C Excavator 4W-7018 4W-7019 0R-3536 0R-3422 original new injector

The Perkins 0R-1745 fuel injector nozzle is engineered as an OEM equivalent replacement component for Perkins 3406, 3406B, 3406C, 3408, 3408B, 3408C, 3412, and 3412C diesel engines. Manufactured from hardened alloy steel with micron-level tolerance control, this nozzle delivers consistent fuel delivery, excellent atomization, and dependable combustion performance across demanding industrial operating environments. Cross-referenced with part numbers 4W-7018 and 4W7018, the component integrates seamlessly into existing fuel system configurations without requiring modifications.

Designed for heavy-duty applications, the 0R-1745 injector nozzle serves construction machinery, mining trucks, excavators, wheel loaders, bulldozers, drilling rigs, marine propulsion engines, work boats, generator sets, and oilfield equipment. Its high wear resistance and precision-machined spray geometry produce improved combustion efficiency, reduced fuel consumption, increased engine power output, and lower carbon deposits. Operators benefit from decreased exhaust smoke and elevated engine reliability, supporting long service intervals in remote and high-load operating conditions.

Installation requires clean diesel fuel, contamination-free injector lines, and proper seating of new sealing washers and O-rings. Technicians should inspect the injector body for wear before assembly, verify nozzle calibration following installation, and conduct fuel leak inspections and operational engine testing. Routine monitoring of exhaust smoke, throttle response, and engine performance indicators helps identify early signs of nozzle degradation, allowing scheduled replacement before secondary damage occurs.
