The Caterpillar 10R-7223 Fuel Injector is a precision-engineered electronic unit injector designed for CAT C9 and C9 ACERT diesel engine platforms. Manufactured to OEM-equivalent quality standards, it delivers accurate fuel metering, superior atomization, and optimized combustion efficiency under severe operating conditions. As a direct replacement for OE numbers 10R-7223, 326-4701, 326-4702, and 326-4703, this new injector restores factory-level fuel delivery and helps maintain emissions compliance.
Operating as a high-pressure electronically controlled fuel delivery device, the injector solenoid opens a precision needle valve upon receiving the control signal, atomizing fuel through multiple nozzle holes into the combustion chamber. The fine fuel mist ensures efficient air-fuel mixing and complete combustion, delivering lower fuel consumption, reduced exhaust emissions, enhanced engine response, and increased power output. Hardened alloy steel internal components resist wear, while protective surface treatment guards against fuel contamination and moisture for extended service life.
The 10R-7223 is widely used across Caterpillar C9 industrial, generator, marine, and construction engines, and is commonly installed in CAT 330D, 336D, and 345D excavators, 966H, 972H, and 980H wheel loaders, 140M and 160M motor graders, generator sets, and industrial power units. For dependable performance, use high-quality diesel fuel, replace fuel filters regularly, drain water separators routinely, and replace all O-rings and sealing washers during installation, followed by fuel system bleeding. A 12-month warranty supports global B2B supply.
