original 10R-1258 Common Rail Fuel Injector for C12 C10 Diesel Engine Excavator Parts Injection Valve Pump Injector Assembly 212-3462 212-3465 212-3468 original new injector

Engineered for heavy duty diesel power systems, the 10R-1258 Fuel Injector delivers dependable high-pressure fuel atomization for C10 and C12 engine platforms. Cross referenced with 212-3468, this remanufactured injector is built to OEM specifications and serves as a direct replacement for industrial, marine, construction, mining, and power generation applications where reliable combustion and stable output are essential.

Internally, the injector features industrial-grade hardened steel components and corrosion resistant internal parts, ensuring extended service life under continuous heavy loads. Precision calibrated fuel delivery supports improved fuel atomization, higher combustion efficiency, increased engine power, reduced fuel consumption, lower exhaust emissions, and stable engine operation. Suitable installations include excavators, loaders, generator sets, marine engines, oilfield equipment, and general industrial machinery requiring OEM-level injection performance.

Installation should always begin with cleaning the injector bore, replacing sealing washers and O-rings, and using calibrated torque tools. Prime the fuel system before startup and complete a leak inspection after installation. For optimal service life, use clean diesel fuel, replace filters regularly, avoid water contamination, monitor fuel pressure, and conduct periodic injector testing to prevent fault conditions such as injection failure, cylinder misfire, fuel pressure imbalance, injector circuit malfunction, or poor combustion. Backed by a 12-month warranty with global shipping available.
