Caterpillar original Common Rail Fuel Injector 10R-1003 Cross Reference 350-7555, 212-3468, Diesel Engine Fuel Injector 212-3476 Replacement for OEM, Fits CAT C10 C12 Engine original new injector

Built to meet the fuel delivery demands of Caterpillar C12 engine platforms, the 212-3476 diesel fuel injector (OE 2123476) is a high-pressure electronic unit injector manufactured to OEM-equivalent specifications. Supplied in new condition, it serves heavy-duty trucks, construction excavators, wheel loaders, motor graders, mining trucks, diesel generator sets, marine engines, industrial pump systems, compressor units, and power generation equipment across global aftermarket and OEM service networks.

Precision-machined internal passages and an optimized fuel spray pattern allow the CAT 212-3476 injector to meter and atomize diesel fuel at extremely high pressure, producing a fine mist that mixes thoroughly with compressed air for efficient combustion. Wear-resistant internal components and corrosion-resistant construction materials deliver long-term durability under demanding operating environments, while OEM-standard manufacturing supports reliable, consistent operation. The result is improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, enhanced horsepower output, stable cold-start performance, and extended engine service life.

As a direct replacement component, installation requires fuel system cleaning and injector seat inspection, with torque values following Caterpillar specifications; ECU verification, fuel filter replacement, and system pressure testing are recommended. Suggested maintenance includes fuel filter inspection every 250 hours, fuel system inspection every 500 hours, and injector performance analysis every 1,000 hours. Manufacturer warranty is available for this industrial-grade injector. Contact our sales team for quotations, cross-reference verification, and technical support.
