Precision fuel delivery is the foundation of dependable diesel performance, and the erpillar C6 Fuel Injector 10R-7673 (OEM 10R7673) is engineered to deliver exactly that. Designed for C6 series engines, this high-precision common rail injector meters fuel with microsecond-level electronic timing and atomizes it through a multi-hole nozzle, ensuring complete combustion with fewer unburned hydrocarbons and lower emissions. The result is quick engine startup, stable idling, and optimized fuel economy for excavators, loaders, generators, and other heavy equipment.
Built for industrial duty cycles, the 10R-7673 is CNC-machined from high-grade steel alloy to tight tolerances, delivering strong resistance to wear, corrosion, thermal shock, and vibration from -40°C to 150°C. Operating at 1600–1800 bar with a response time under 1 ms, it sustains continuous 24/7 operation while its optimized spray pattern improves atomization and cuts fuel consumption. Every unit is OEM-grade tested under ISO 9001 and ISO/TS 16949 standards, giving fleets in construction, mining, agriculture, and power generation a durable, low-maintenance injection solution.
For parts distributors and fleet managers, broad interchangeability adds further value: the 10R-7673 cross-references erpillar 326-4703, 3264703, 317-8878, 10R-7654, and 10R7655, plus Bosch 0445110378, Delphi 7135-405, Stanadyne 148-654, and Denso 23670-30120. It fits C6.2, C6.4, C6.6, and C6.7 diesel engines across tractors, excavators, skid steers, and mining vehicles, and is backed by a 12-month / 1000-operating-hour warranty for confident, long-term service.
