original For 3408 3412E Diesel Engine Fuel Injector Assembly 173-4061, Cross Reference 198-4752, Fits Tractor D10R D9R 657E 631E 637E 651E, Replacement for OEM 10R-1267, 173-9268 original new injector

The 173-4061 Fuel Injector Assembly is an OEM-equivalent replacement for 3412 series diesel engines, including 3412, 3412B, 3412C and 3412 DITA configurations. Cross-referenced to 1734061, 0R-8477, 10R-0955 and 20R-2055, it supports marine, generator, industrial and mining applications. Equipment coverage includes diesel generator sets, marine power systems, offshore platforms, mining trucks, construction machinery, oilfield equipment, industrial power plants and emergency backup generators.

The injector meters diesel fuel into the combustion chamber at the correct timing and pressure. As pressure builds, the needle lifts and fuel is atomized through precision nozzle holes, creating a fine mist that mixes with compressed air for combustion. Documented benefits include improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, increased engine power output, stable operation and extended engine service life. Its industrial feature set also covers high-precision fuel delivery, durability, wear resistance, thermal stability, long service life and direct OEM fitment.

Supplied new, each injector is 100% tested before shipment and covered by a 12-month warranty. Installation requires cleaning the mounting area, inspecting the injector bore, replacing sealing components, tightening to specifications, bleeding the fuel system and checking for leaks. Ongoing best practices include using clean diesel fuel, replacing fuel filters regularly, preventing water contamination, monitoring fuel pressure and performing periodic injector inspections, supporting dependable maintenance planning for industrial operators.
