original 10R-1258 Common Rail Fuel Injector for C12 Engine Excavator Truck Diesel Fuel Injector Replacement for OEM 212-3462 10R-0967 2123468 original new injector

Engineered for demanding heavy-duty operating cycles, this C12 Fuel Injector (OE 10R-1258, cross reference 212-3468) delivers precise high-pressure diesel atomization for C12 inline 6-cylinder turbocharged engines. It is a direct fit for C12 Industrial, Generator, Marine and Construction Equipment Engines using electronic fuel injection and high-pressure fuel system architecture, with operating pressures that can exceed 2,000 bar / 29,000 PSI under full load.

The injector features precision CNC-machined nozzle technology to ensure uniform spray patterns, precise fuel metering and consistent combustion across the full load range. Internal components include hardened valve assemblies, wear-resistant needle valves, precision control springs and a high-strength alloy body, all rated for high-temperature resistance in extreme mining, desert, continuous generator and heavy haul truck environments. Optimized combustion efficiency reduces fuel consumption and lowers operating cost, while the robust design supports extended service life for fleet maintenance programs and continuous duty applications.

Widely deployed across North American fleet trucks and mining equipment, European industrial and marine power units, Middle East oil field equipment, African mining and power generation machinery, and Asia-Pacific port and industrial systems. Recommended maintenance: inspect fuel leakage, wiring and fuel lines every 250 hours; verify spray pattern and fuel balance every 500 hours; perform injector performance testing, flow rate verification and electronic diagnostics every 1,000 hours to sustain peak reliability.
