Caterpillar original For Caterpillar C9 Engine Common Rail Fuel Injector 245-3516, 20R-8060, for Excavator Replacement for Diesel Parts, Cross Reference 10R-4764, 387-9438 original new injector

Precision-engineered for Caterpillar C9 and C9 ACERT diesel engine platforms, the 245-3516 common rail fuel injector is a factory-grade diesel injection assembly manufactured to strict OEM-equivalent standards. Produced in ISO-certified manufacturing facilities, every unit is built to integrate seamlessly with compatible CAT high-pressure fuel systems, eliminating fitment discrepancies for maintenance technicians and heavy equipment fleet operators. It serves as a core fuel system component that supports stable engine performance under sustained heavy-load operating conditions.

Operating via electronically signal-coordinated fuel delivery, the injector meters exact volumes of diesel and atomizes fuel into microscopic droplets to form an optimal air-fuel mixture in the combustion chamber. This calibrated delivery boosts combustion efficiency and power output, while reducing fuel consumption and exhaust emissions. Accurate fuel metering also minimizes premature cylinder wear, piston damage, turbocharger contamination and carbon deposit buildup to extend overall engine service life.

Built with corrosion-resistant materials and high-pressure handling capability, the injector delivers industrial-grade reliability and long service life for demanding use cases. It fits a broad range of CAT heavy equipment, including excavators, wheel loaders, motor graders, generator sets, and mining, marine and industrial power units, covering construction, mining, power generation, marine and industrial sectors. Units are delivered in heavy-duty industrial packaging, with warranty available upon request for B2B customers.
