original 235-5261 Mechanical Fuel Injector for C9 C-9 Excavator Engine 20R-9433 328-2577 235-9649 Diesel Fuel Injector Nozzle Pump Construction Machinery Parts original new injector

Engineered as a direct OEM equivalent replacement for the C9 diesel platform, the 235-5261 Fuel Injector Assembly delivers precision-controlled fuel atomization for demanding industrial, construction, marine and power generation applications. Cross-referenced with 10R-7675 and 328-2574, this injector is fully interchangeable with original units fitted to C9, C9 ACERT, C9 Industrial, C9 Marine and C9 Generator engines, providing operators with a reliable service part backed by consistent factory-calibrated performance.

The injector features a precision machined body, high-pressure fuel delivery capability, optimized spray atomization geometry, and electronic injection control compatible with the ECM-managed common rail system. Corrosion-resistant construction and heavy-duty industrial design ensure long service life in harsh operating environments, including mining sites, off-highway machinery and continuous-duty gensets. Benefits include improved combustion efficiency, better horsepower output, reduced fuel consumption, lower emissions, stable idle performance and reduced downtime, making it suitable for excavators, wheel loaders, motor graders, compactors, dozers and industrial power units.

Installation requires disconnecting the fuel supply, cleaning the injector bore, inspecting the seat, fitting new sealing components, tightening to specified torque, priming the system and performing leak and operational tests. For diagnostics, flow testing, leak-off testing, fuel pressure testing, ECM scanning, spray pattern inspection and cylinder balance testing are recommended. Serial number verification is advised before ordering. Available globally across North America, South America, Europe, Middle East, Africa, Southeast Asia, Australia and Central Asia.
