original 10R-9617 Common Rail Fuel Injector for C3500B 3516B Engine 797 793C 789C 793D Mining Truck Excavator Aftermarket Diesel Injector GP original new injector

Engineered for demanding heavy-duty operations, the 10R-9617 Electronic Unit Fuel Injector is a precision-manufactured component designed specifically for the 3512B V12 diesel engine platform. This injector is fully interchangeable with cross reference numbers 249-0713, 387-9433, 20R-8063, 0R-8477, and 212-8476, delivering reliable performance across a wide range of industrial diesel applications. Each unit is 100% quality tested to ensure precise fuel calibration and consistent atomization under high pressure operating conditions.

Built with high-precision machining, corrosion-resistant materials, and an industrial-grade sealing system, the 10R-9617 injector features a heavy-duty internal valve system engineered for high-temperature and heavy-load service. Advanced atomization technology delivers improved fuel economy, reduced emissions, better combustion efficiency, and higher engine power output. The long service life design lowers total operating costs and extends the operational lifespan of 3512B engines deployed in power generation systems, marine vessels, mining haul trucks, offshore platforms, and oil & gas equipment.

Recommended installation procedures include thorough cleaning of the fuel system, inspection of the cylinder head injector bore, replacement of sealing washers and O-rings, and adherence to specified torque values, followed by fuel pressure testing and injector balance verification. Regular maintenance using high-quality diesel fuel and scheduled filter replacement prevents common issues such as hard starting, white or black smoke, power reduction, and misfire conditions in critical industrial installations.
