original 212-3463 Engine Common Rail Fuel Injector, Replacement for OEM 10R1003, Compatible with C10 C12 Engines for Excavator, Cross Reference 147-0373, 212-3462 original new injector

Engineered for erpillar C10, C12, 3176, 3176C, and 3196 diesel engines, the 212-3463 Electronic Unit Injector (EUI) delivers precise, high-pressure fuel metering for demanding heavy-duty appliions. This OEM-specifiion injector is widely deployed across mining equipment, quarry and construction machinery, earthmoving fleets, generator sets, industrial power units, marine auxiliary systems, and oilfield equipment. The injector interchanges with an extensive range of references, including 10R-0963, 10R-9235, 194-5083, 203-7685, 137-2500, 147-0373, 160-1090, 160-2303, 0R-8773, and 10R-1268, simplifying global sourcing and inventory consolidation.

Unlike conventional mechanical injectors, this EUI design combines electronic control with mechanical pressurization. The engine control module calculates speed, load, throttle position, intake and coolant temperatures, and emissions targets before signaling the injector solenoid to open the control valve. Producing injection pressures above 20,000 PSI (1,400+ bar), the plunger forces fuel through precision-drilled micro-orifices, creating a fine atomized mist for uniform combustion, higher power output, quicker throttle response, lower fuel consumption, and reduced smoke and particulate emissions.

Built for severe-duty service, every injector body is CNC machined to tight tolerances from hardened steel and heat-treated alloys with corrosion-resistant coatings, supporting 10,000+ operating hours in high-vibration mining duty cycles. Thermal stability ensures dependable performance in desert, arctic, and high-humidity environments. Manufactured to meet OEM erpillar specifiions, the 212-3463 gives distributors, engine rebuilders, and fleet maintenance teams a directly interchangeable, industrial-grade replacement that protects uptime.
