original 173-9268 Diesel Fuel Injector Nozzle 1739268 for 3126B 3126E 3126 Engine Fuel Injector Replacement for OEM 173-9267 169-7411 original new injector

Engineered for the 3126-series inline six-cylinder diesel platform, the 173-9268 HEUI fuel injector is a heavy-duty replacement unit built to match the operating characteristics of 3126, 3126B, and 3126E engines. Cross-referenced against a wide OE database including 1739268, CA1739268, 0R9348, 0R9349, EX639348, EX639349, 145-9360, 155-1819, 118-1320, 173-1012, 173-4566, 173-9267, 173-9379, 173-9380, 188-1320, 196-1401, 222-5965, 222-5967, 10R-8999, and 10R-9238, this injector serves as a direct fit for global aftermarket, rebuild, and OEM-style service applications.

The injector integrates electronic solenoid control with hydraulic intensification: the ECM manages injection timing and duration, high-pressure engine oil actuates the plunger, and the internal system pressurizes diesel fuel for fine spray atomization inside the combustion chamber. This design delivers precision fuel metering, stable idle performance, and consistent power output under heavy load. Multiple supply conditions are available, including new aftermarket, remanufactured, rebuilt, and exchange units, with full six-injector engine sets offered for overhaul programs. Each unit is testable and export-ready.

Typical applications include medium-duty trucks, buses, excavators, loaders, generator sets, marine auxiliary engines, and industrial power units across North America, Latin America, Europe, the Middle East, Africa, Southeast Asia, and Australia. Correct fitment must be confirmed by the original injector number, engine serial number, and engine arrangement. Professional installation, clean fuel, and disciplined engine oil maintenance are essential for long HEUI injector service life.
