Caterpillar original Replacement Common Rail Fuel Injector 10R-9617 373-4087 for Caterpillar C3500B 3516B Engine, Cross Reference 246-1854, 250-1313, for 797 Excavator and Truck original new injector

Engineered exclusively for CAT 3512B heavy-duty diesel engine platforms, the 10R-9617 common rail fuel injector is a precision-machined replacement component built to align with strict OEM specifications. Validated for all 3512B engine variants covering generator, marine, offshore, industrial and mining configurations, it serves critical operations across power generation, oil and gas, marine, mining and industrial power sectors, delivering stable performance even under harsh, high-load working conditions.

The injector draws pressurized diesel from the high-pressure common rail, regulates fuel flow via precision internal components, and opens its calibrated nozzle to atomize fuel into microscopic droplets for optimal air-fuel mixing. This controlled injection process boosts combustion efficiency and power output, improves fuel economy, reduces exhaust emissions, and lowers long-term operating costs. Its industrial-grade design incorporates corrosion-resistant materials, heavy-duty sealing systems and high-temperature resistance to support extended service life.

Manufactured to OEM equivalent quality standards, each 10R-9617 injector undergoes factory calibration to ensure consistent fuel delivery performance. It is shipped in industrial export packaging for long-distance logistics protection and comes with a 12-month warranty. To maximize service life, follow Caterpillar installation torque guidelines, conduct post-install pressure and idle testing, replace fuel filters regularly, and use only high-quality diesel fuel.
