Caterpillar original 10R-3147 Common Rail Fuel Injector Assembly for C11 C13 Engine 966H R1600H Excavator Replacement for OEM new injector original new injector

Engineered to meet the demanding fuel delivery requirements of heavy-duty diesel engines, this replacement fuel injector 10R-3147 (also referenced as 2490712 and CA10R3147) is designed for use in Caterpillar C11 and C13 engine platforms. The injector features a precision nozzle design and hardened steel construction, delivering consistent high-pressure atomization for stable combustion under continuous industrial loads. It is a direct-fit component for operators seeking reliable, OEM-specification replacement parts.

This injection assembly supports a wide range of equipment, including 966H, 972H, 980H, and 980K wheel loaders, as well as generator sets, power units, pump drives, and marine auxiliary systems. Performance benefits include improved fuel economy, lower exhaust emissions, enhanced combustion efficiency, increased horsepower output, and reduced overall fuel consumption. Corrosion-resistant materials and leak-resistant sealing ensure long service life across construction, mining, power generation, and industrial manufacturing environments where uptime is critical.

Common symptoms indicating injector replacement include hard starting, engine hesitation, power loss, excessive exhaust smoke, fuel leakage, poor fuel economy, and diagnostic fault codes. To maximize service life, operators should use high-quality diesel fuel, replace fuel filters on schedule, avoid contaminated fuel sources, monitor fuel pressure, and perform injector calibration when required. Recommended companion components include injector seal kits, O-ring kits, fuel filters, valve cover gaskets, and injector harness inspection for complete fuel system service.
