original 10R-9002 Common Rail Diesel Fuel Injector for C9 Engine 336 336D Excavator 235-5261 236-0957 225-0117 Construction Machinery Spare Parts original new injector

Engineered as a direct OEM replacement, the 10R-9002 Common Rail Diesel Fuel Injector delivers precision-metered fuel injection for . C9, C9 ACERT, and C9.3 industrial engines. This assembly is fully interchangeable with cross reference numbers 10R9002, 326-1645, 326-1646, 326-1647, 326-1648, and 326-1649, providing a reliable service part solution for heavy equipment operators, fleet maintenance teams, and industrial engine rebuilders worldwide.

Manufactured with CNC machined components, a precision ground needle valve, a hardened steel control valve, and a wear-resistant nozzle, the injector is finished with corrosion resistant surface treatment for long service life under demanding conditions. Performance benefits include high injection accuracy, stable fuel delivery, reduced fuel consumption, improved horsepower output, lower exhaust emissions, and extended engine longevity. The heavy duty design withstands high temperature and high pressure operation, making it suitable for continuous industrial duty cycles in excavators, wheel loaders, bulldozers, motor graders, mining trucks, and generator sets.

Installation best practices include thoroughly cleaning the injector bore, inspecting fuel rail condition, replacing sealing washers, lubricating O-rings, installing the injector vertically, applying specified torque, performing ECM calibration, and conducting a fuel leakage test before final verification. Operators are advised to use ultra-clean diesel fuel, replace filters regularly, monitor fuel pressure, avoid water contamination, and perform periodic injector testing to maximize reliability across construction, mining, power generation, oil and gas, and marine applications.
