Caterpillar original Common Rail Fuel Injector 246-1854 10R-7238 Replacement for OEM 392-0219 386-1771 for Caterpillar 3508C 3512C 3516C Construction Machinery Parts original new injector

The Caterpillar 10R-7238 is a high-precision diesel fuel injector engineered exclusively for CAT 3512B series industrial diesel engines, including industrial, generator, marine, offshore and heavy-duty power unit variants. As a brand-new OEM-equivalent component, it is manufactured to strict original Caterpillar specifications and industrial quality standards, serving as a core element of the engine’s fuel injection system to support consistent, reliable operation.

Built with micron-level manufacturing tolerance and industrial-grade corrosion protection, the injector operates stably across a temperature range of -40°C to +200°C, even in harsh mining, marine, offshore and power generation environments. Its precision-machined nozzle delivers accurate fuel metering and optimized atomization based on real-time engine load, speed and operating conditions, boosting combustion efficiency, reducing fuel consumption and exhaust emissions, minimizing carbon deposits, and maintaining stable power output and smooth idle for continuous-duty applications.

It is compatible with a wide range of 3512B-powered equipment, such as diesel generator sets, marine engines, mining equipment, oil and gas facilities, industrial power systems, construction machinery and emergency backup generators. The part comes with a 12-month warranty; following official installation guidelines and the recommended preventive maintenance schedule will further extend its service life and sustain optimal engine performance.
