original 10R-1814 Rail Fuel Injector for C12 C10 Engine 10R-9235 116-8805 Replacement for OEM new injector original new injector

The 10R-1814 electronic unit injector is engineered specifically for C10 and C12 diesel engines equipped with electronically controlled fuel systems. As a remanufactured OE-type injector, it is built to original factory specifications, ensuring direct-fit compatibility without the need for modifications or recalibration. This injector is widely used across heavy-duty trucks, wheel loaders, excavators, motor graders, dozers, industrial power units, diesel generator sets, mining equipment, and other off-highway machinery, making it a reliable replacement component for global aftermarket distribution.

Precision fuel metering, stable atomization, and balanced cylinder delivery are the key functional advantages of the 10R-1814 injector. It maintains consistent combustion across all cylinders, improves load response, reduces exhaust smoke, and helps restore lost power in aging C10 and C12 engines. The injector is available as a single replacement unit or as a complete matched 6-piece set, which is recommended for high-hour engines to ensure even performance and minimize unplanned downtime. Core return may apply for remanufactured supply.

Proper maintenance is essential to maximize injector service life. Operators should use clean diesel fuel, follow scheduled fuel filter replacement, drain water separators regularly, keep the fuel tank free of contamination, and inspect injector wiring and connectors periodically. Common failure symptoms include hard starting, rough idle, black or white smoke, power loss, high fuel consumption, engine knock, misfire, and electronic fault codes. When symptoms appear, fuel pressure testing, return flow testing, cylinder balance testing, ECM diagnostic scanning, and fuel contamination analysis are recommended diagnostic procedures to identify and confirm injector-related issues.
