Caterpillar original Caterpillar 267-9722 diesel fuel injector replacement for OEM C9 common rail engine original new injector

The Caterpillar C9 HEUI fuel injector 267-9722 is engineered as a direct OEM replacement for the C9 engine platform, delivering stable fuel delivery and improved engine power across demanding industrial applications. Utilizing HEUI hydraulic pressure fuel injection combined with electronic ECM control, this injector is precision-engineered for optimized fuel atomization, enhanced combustion efficiency, and consistent engine power output. The assembly supports reduced fuel consumption while maintaining heavy-duty performance standards required for excavators, wheel loaders, off-highway trucks, generator sets, and industrial power units operating in construction, mining, power generation, marine, oilfield, and heavy transportation environments.

Manufactured to OEM quality specifications, the 267-9722 injector assembly offers extended service life and global market acceptance as a reliable component within the Caterpillar fuel system. It is cross-referenced with authorized alternative part numbers including 267-9710, 267-9717, 293-4074, 328-2580, and 387-9431, as well as remanufactured references 10R-7223 and 10R-9003. This broad compatibility allows fleet operators and service technicians to source a verified replacement injector that matches original equipment tolerances for the CAT C9, CAT C9 ACERT, and related generator and marine engine configurations.

Proper installation of the 267-9722 HEUI injector requires adherence to standard maintenance practices to ensure long-term reliability. Technicians should use OEM-grade fuel filters, drain water separators regularly, and maintain a clean fuel supply throughout the system. Before installation, the injector bore must be cleaned, injector O-rings replaced, and new sealing washers installed following Caterpillar torque specifications. Periodic fuel pressure system inspection and injector balance testing are recommended, along with injector coding or calibration when required to restore optimal engine performance.
