original For 3412E Engine, 0R-9803 Diesel Common Rail Injector, 232-1173, Replacement for OEM 232-1168, for Truck Excavator 375 5080 D9N 773D 992C original new injector

Designed for demanding 3412 fuel-system service, the 0R-9803 is a remanufactured diesel fuel injector built to OEM specifications and tested under strict fuel-system performance standards. It delivers a precisely metered quantity of diesel into the combustion chamber at high pressure, supporting accurate fuel atomization and efficient combustion. The injector is intended for 3412, 3412B, 3412C and 3412 DITA engines, including marine, generator-set and industrial power-system configurations.

Its precision-machined nozzle assembly, OEM fuel-flow calibration and high-pressure injection capability help promote improved combustion efficiency, better atomization and reliable engine operation. Wear-resistant internal components and corrosion-resistant materials support long service life in heavy-duty applications, while factory testing provides quality assurance. Potential operating benefits include reduced exhaust smoke, lower fuel consumption, increased engine power and reduced cylinder wear. Production is specified as ISO certified, and the unit installs in the cylinder-head fuel system.

The 0R-9803 is suitable for generator sets, marine engines, mining equipment, construction machinery, oilfield equipment, industrial power units and continuous power-generation systems. Cross references include 0R9803, 4W-7018, 4W7018, 7E-6408, 7E6408, 8N-7005 and 8N7005. Because references can vary by engine arrangement, calibration code, emissions configuration and regional service updates, serial-number verification is recommended before purchase. During installation, replace fuel filters, clean the injector bore, inspect fuel lines and sealing surfaces, follow torque specifications, bleed air from the fuel system and perform an engine performance test.
