original 10R-1814 Common Rail Fuel Injector for C12 C10 Excavator Truck Engine Diesel Injector Assembly Replacement for OEM 10R-9235 10R-1264 0R-4987 original new injector

Engineered for electronically controlled C10 and C12 diesel fuel systems, the 10R-1814 injector is a heavy-duty replacement unit designed to deliver precise metering, stable spray atomization, and consistent cylinder-to-cylinder balance. Cross-referenced with 119-8784, 215-3198, 9295918, and 9X-7317, this reman-type electronic unit injector serves as a direct interchange solution for global aftermarket supply, supporting repair shops, fleet operators, diesel rebuilders, and parts distributors that require dependable fuel system components.

Typical applications include heavy-duty truck engines, wheel loaders, excavators, motor graders, dozers, industrial power units, diesel generator sets, and mining equipment. Because C10 and C12 platforms use several engine arrangements, buyers should confirm the engine model, engine serial number, original injector part number, and fuel system configuration before installation. The 10R-1814 supports improved load response, cleaner combustion, and stable idle behavior, helping reduce black smoke, misfire, and power loss commonly reported in high-hour engines.

For long service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain water separators, and inspect injector wiring and connectors. When symptoms such as hard starting, rough idle, engine knock, or fault codes appear, cylinder balance testing, injector return flow testing, and ECM diagnostic scanning are recommended. On high-hour C10 and C12 engines, replacing injectors as a matched set improves balance and reduces repeated downtime across demanding industrial duty cycles.
