original 10R-1267 Common Rail Fuel Injector for C7 C9 Diesel Engine Excavator Injector Assembly Replacement for OEM 232-1171 2321171 10R1267 original new injector

Engineered for demanding operational environments, the 10R-1267 fuel injector delivers reliable performance across the 3412, 3412C, and 3412E V12 diesel engine platforms. Manufactured from high-strength steel and precision alloys, this injector withstands extreme temperatures, corrosive fuel conditions, and continuous heavy-duty cycles typical in industrial, marine, and power generation applications. The multi-hole nozzle design ensures uniform fuel atomization, reducing emissions while optimizing combustion efficiency. Cross-reference numbers 10R-1267, 236-7846, and 0R-1267 provide flexibility for global sourcing.

Designed to match OEM specifications for pressure, timing, and spray geometry, this injector operates within a 2200–2500 bar pressure range and is compatible with both mechanical and electronic injection systems. Applications include the 3412G industrial generator, 3412 marine engines, 3400 series excavators, and 3450 mining loaders. Precision machining ensures consistent fuel flow rates and repeatable spray patterns, making it ideal for heavy equipment manufacturers, mining and construction operations, and oil & gas field machinery requiring uninterrupted uptime.

Installation requires a clean cylinder head, pre-lubrication with clean diesel, and OEM torque settings of 35–40 Nm on mounting bolts. Verify alignment with the fuel rail and inspect for leaks after installation. Recommended maintenance includes inspection every 500 operating hours, regular fuel filter cleaning, and replacement when spray degradation, misfire, excess smoke, or hard-start symptoms occur. Following OEM service intervals maximizes injector service life and protects the entire fuel system.
