Caterpillar original 212-3463 Engine Common Rail Fuel Injector for C12 C10 CAT Excavator Diesel Replacement for OEM original new injector

The Caterpillar Electronic Unit Injector listed under the authorized Caterpillar electronic unit injector range is engineered as a direct OEM replacement for C12, C12 ACERT, C10, 3176, 3176B, 3176C, and 3196 diesel engine platforms. It integrates high-pressure fuel generation, precise electronic timing control, fuel metering, and high-efficiency atomization into a single EUI assembly. ECM commands determine injection timing, duration, and fuel quantity, while the unit delivers injection pressures up to 20,000 PSI (1,400 Bar) to support complete combustion in heavy-duty operating environments.

Manufactured with premium hardened steel components and advanced anti-corrosion coating, this injector is built for long service life, thermal stability under high exhaust gas temperatures, and reliable fleet operation across mining, construction, transportation, and power generation applications. Precision-machined nozzle orifices produce fine fuel droplets for accurate computer-calibrated delivery. The unit installs as an OEM direct replacement without modification, supporting articulated trucks, motor graders, excavators, loaders, mining equipment, diesel generator sets, vocational trucks, auxiliary marine engines, and oilfield power units.

Before installation, verify the authorized part number against the engine serial number and replace all sealing washers and O-rings. Follow Caterpillar torque specifications during installation, prime the fuel system, and perform injector trim calibration when applicable. Authorized cross reference numbers are available for confirm identification, interchange, and fleet standardization across multiple Caterpillar C-series platforms.
