original 20R-1262 Common Rail Diesel Fuel Injector for C3500B Engine 5130B 5230B Excavator High Pressure Fuel Nozzle Replacement OEM 392-0226 3920226 original new injector

Engineered for demanding heavy-duty operations, the 20R-1262 Fuel Injector is a genuine OEM component designed specifically for the . 3512B diesel engine platform. This precision-crafted injector assembly delivers accurate fuel atomization under extreme pressure, ensuring optimal combustion performance across industrial, marine, and power generation applications. Cross-referenced with alternative part number 10R-0955, the 20R-1262 is fully interchangeable within the 3512B engine family, including 3512B HD, 3512B Marine, 3512B Generator, and 3512B Industrial variants.

Constructed with heat-treated internal components and corrosion-resistant materials, this injector features a precision nozzle design that promotes balanced fuel flow and consistent spray patterns. Every unit undergoes rigorous leak testing and is manufactured to strict OEM tolerances, guaranteeing industrial-grade reliability under continuous operating conditions. Key performance benefits include improved combustion efficiency, higher power output, lower fuel consumption, reduced exhaust emissions, enhanced cold start performance, and extended overall engine service life, making it a preferred choice for mission-critical equipment.

Typical field applications include prime power generators, emergency backup systems, surface and underground mining trucks, offshore support vessels, drilling rigs, pumping stations, and compressor packages. For optimal service life, always inspect fuel lines before installation, clean injector seating surfaces, use new seals and washers, and complete full fuel system bleeding. Regular filter replacement, clean diesel fuel usage, and periodic injector calibration checks during major service intervals ensure sustained performance and reliability.
