Engineered to meet the rigorous demands of heavy-duty diesel operations, the Caterpillar 10R-9617 fuel injector is a precision-built injection component developed for the CAT 3512B engine platform. This OEM-equivalent injector supports a wide range of installations, including 3512B generator engines, marine propulsion units, offshore power systems, mining engines, and industrial power units, making it a dependable sourcing choice for fleet operators, equipment dealers, and maintenance providers worldwide.

Functioning as a high-accuracy fuel metering device, the 10R-9617 receives diesel from the high-pressure fuel rail and delivers finely atomized fuel into the combustion chamber at precisely controlled pressure and timing. High-precision machining, OEM fuel calibration, advanced atomization technology, and a heavy-duty internal valve system work together to improve combustion efficiency, increase power output, reduce emissions, and lower fuel consumption. Corrosion-resistant materials, an industrial-grade sealing system, and high-temperature resistance ensure stable performance and long service life under continuous heavy-load operation.

For simplified procurement and inventory management, this injector cross-references multiple part numbers, including 10R9617, 249-0713, 2490713, 387-9433, 3879433, 20R-8063, 20R8063, 0R-8477, 0R8477, 212-8476, and 2128476; verification against the engine serial number is recommended before ordering.
