Caterpillar original Diesel Fuel Injector 267-3361 254-4330 267-9722 387-9427 – OEM Replacement for Caterpillar C9 Excavator, for heavy duty diesel engine application original new injector

The 267-3361 is an original Caterpillar (CAT) electronic diesel fuel injector engineered for C9 and C9.3 series engine platforms. It is compatible with a wide range of CAT heavy-duty equipment, including 325D, 330D, 336D and 345D excavators, 966H, 972H and 980H wheel loaders, 730 articulated trucks, as well as industrial power units and generator sets. The component serves core industrial sectors spanning construction, mining, industrial applications, power generation and marine auxiliary operations, fitting demanding high-load working environments.

Operated via ECM electronic control signals, the injector activates its solenoid and needle valve to deliver precisely metered, fully atomized high-pressure diesel into combustion chambers, optimizing combustion efficiency, reducing fuel consumption and exhaust emissions, and boosting engine power output. Built with industrial-grade materials, it features an OEM-calibrated flow rate, precision-machined nozzle, wear-resistant internal parts and corrosion-resistant coating, supporting stable long-term operation under high-temperature conditions and extending overall engine service life.

Manufactured to stringent OEM quality standards, the 267-3361 injector comes with a 12-month warranty, industrial export standard packaging and global shipping support, with a minimum order quantity of 1 piece and available OEM services. For reliable performance, users are recommended to follow official installation specifications, use clean diesel, replace fuel filters regularly, and conduct routine diagnostic checks including ECM fault code analysis and return flow tests to identify potential issues early.
