Caterpillar original Common Rail Injector Cross Reference 328-2574, 328-2577, 10R-7223, Fuel Injector 320-2940 Replacement for Diesel Engine Auto Parts, C9 Engine, Excavator original new injector

The Caterpillar (CAT) 320-2940 common rail fuel injector is a precision-engineered diesel fuel system component designed for the full range of Caterpillar C9 engine variants, including standard C9, C9 ACERT, industrial, power generation and marine models. As an OEM-equivalent direct replacement for worn, damaged or performance-degraded original injectors, it is compatible with a broad portfolio of heavy-duty CAT equipment. Always verify the engine serial number, arrangement number and injector calibration code before placing an order.

Controlled by electronic signals from the engine ECM, the injector activates its solenoid to lift the needle, atomizing high-pressure diesel into ultra-fine particles for optimized air-fuel mixing. This design improves combustion efficiency, enhances power output, boosts fuel economy, reduces black smoke and exhaust emissions, and delivers faster throttle response. Built to OEM calibration standards, it features high temperature resistance, corrosion protection and stable fuel delivery, with every unit 100% flow bench tested for reliable harsh-environment performance.

The injector comes with a 12-month warranty and follows standardized installation procedures covering bore cleaning, seal replacement, torque application and post-installation performance and ECM diagnostic checks. Routine maintenance recommendations include using high-quality diesel, replacing fuel filters regularly, draining water separators and conducting periodic injector testing. It uses export-grade individual protective packaging with optional OEM branding, and supports worldwide shipping for global B2B clients.
