The erpillar 173-9272 Fuel Injector is a precision-engineered diesel injection assembly designed for the 3126 engine platform, covering 3126, 3126B, 3126E, 3126 ATAAC, Marine, and Industrial variants. Manufactured to OEM-equivalent specifiions, it directly replaces OE 173-9272 (1739272) and cross-references 10R0955, 10R1273, and 20R2057, making it one of the most recognized replacement injectors for 3126 engines worldwide.
As a high-precision electronic fuel metering device, the injector receives ECM signals that determine injection timing, energizing the solenoid to lift the needle and atomize high-pressure diesel through the nozzle holes. The result is precise fuel delivery, improved combustion efficiency, lower fuel consumption, reduced emissions, stable idle operation, and faster throttle response. Industrial-grade construction combines a precision-machined nozzle, high-strength alloy steel components, high-pressure resistance, and corrosion protection to ensure long service life under heavy-duty commercial conditions.
This injector supports a broad equipment base, including Freightliner, Peterbilt, and Kenworth trucks, Blue Bird, Thomas Built, and International school buses, plus generator sets, marine engines, construction equipment, and industrial diesel power units. Because cross-reference numbers may vary by production year, engine serial number, and emission specifiion, serial-number verifiion is recommended before ordering. For reliable performance, clean the injector bore, replace O-rings and seals, install new fuel filters, follow OEM torque procedures, and maintain overall fuel system cleanliness.
