original 10R-3147 Fuel Injector 10R3147 253-1459 for C13 966H Excavator Common Rail new injector original new injector

Engineered specifically for the C11 and C13 diesel platforms, the 10R3147 fuel injector delivers direct-fit compatibility across the 11.1-liter C11, 11.1-liter C11 ACERT, and 12.5-liter C13 engine configurations. This electronic unit injector is designed to serve the same fuel delivery function as the factory-installed component on 966H, 972H, 980H, and 980K wheel loaders, as well as generator sets, power units, pump units, and marine auxiliary equipment operating in construction, mining, power generation, marine, and industrial manufacturing environments.

The injector integrates a precision-machined nozzle, hardened steel internal components, and corrosion-resistant sealing surfaces to withstand sustained high-pressure operation within modern common rail fuel systems. Built to original equipment specification, the unit provides stable injection pressure, consistent atomization, and accurate metering across the full engine operating range. These characteristics support enhanced combustion efficiency, improved fuel economy, lower exhaust emissions, and increased horsepower output while maintaining smooth idle quality and dependable cold-start performance under heavy industrial duty cycles.

Installation is accomplished through direct replacement procedures using existing fuel lines, electrical connections, and mounting hardware, with injector calibration required as part of the commissioning process. Routine maintenance practices—including the use of high-quality diesel fuel, regular fuel filter replacement, avoidance of contaminated fuel, and ongoing monitoring of fuel rail pressure—help preserve injector performance and extend service life. Field diagnostics for hard starting, engine hesitation, power loss, excessive exhaust smoke, fuel leakage, poor fuel economy, and active fault codes frequently point to the fuel injector as the primary component requiring inspection.
