173-9268 HEUI Fuel Injector for Ca-terpillar 3126-Series Diesel Engines
173-9268 Fuel Injector is a hydraulic electronic unit injector (HEUI) designed for selected Ca-terpillar 3126, 3126B and 3126E diesel truck engines. It uses high-pressure engine oil and electronic control to accurately pressurize, meter and inject fuel, supporting stable combustion, efficient fuel use and reliable engine power.
It is suitable for selected medium-duty commercial trucks powered by compatible 3126-series engines. Please verify the original part number, engine serial number, arrangement number and vehicle model before ordering.
The original 173-9268 is listed as discontinued. Common replacement references include 0R-9349, 126-0499, 131-7150, 173-4059, 173-9267, 196-1401 and 222-5967. Professional installation and any required injector setup or ECM calibration should follow the applicable engine service manual.
.Manufactured with wear-resistant precision components and a reliable sealing structure, this injector withstands continuous vibration and demanding working conditions. It helps address hard starting, unstable idle, power loss, excessive fuel consumption and black smoke.
Every Fuel Injector we supply undergoes professional bench testing. Injection quantity, spray pattern, sealing performance and operating stability are inspected to ensure reliable fuel delivery and consistent engine performance.
