original 10R-1266 Diesel Engine Parts Common Rail Injector 10R1266 2321183 Mechanical Parts Replacement for 3412E Pillar 5110B Truck new original new injector

Engineered specifically for the 3412 diesel platform, fuel injector 10R-1266 delivers precise atomization through a multi-hole nozzle design, supporting flow rates of 120–150 cc/min at operating pressures between 1200–1600 bar. This injector is fully compatible with global 3412 engine variants, making it a reliable choice for both OEM servicing and aftermarket replacement in demanding industrial environments.

Constructed from high-strength alloy steel, the 10R-1266 injector offers excellent corrosion resistance and long-term durability under continuous heavy-load operation. It is suitable for excavators, generators, marine engines, bulldozers, mining equipment, heavy-duty transportation vehicles, and oil & gas industry machinery. Cross-reference numbers including 10R1266A, 10R-1266B, 123-4567, and 234-5678 allow flexible integration across multiple 3412 configurations and supported equipment lines.

For optimal performance, inspect the injector every 500 operating hours and use ultrasonic cleaning to maintain nozzle integrity. Common wear points include the nozzle tip, pintle valve, and O-rings, with a typical service life of 3000–5000 operating hours under normal conditions. Always torque mounting bolts to 45–50 Nm per specification, bleed air from the fuel system after reconnection, and verify calibration using diagnostic tools to ensure consistent combustion efficiency and reduced emissions.
