original 196-1401 Diesel Fuel Injector for 3126B 3512B Engine Common Rail Injector Assembly Replacement for OEM 10R-1266 179-6020 1961401 D5N D6N original new injector

Engineered as a direct OEM alternative, the 196-1401 Fuel Injector Assembly delivers precision-calibrated fuel atomization for 3412 series diesel engines. This replacement injector is manufactured to OEM-level dimensional accuracy, ensuring seamless installation, reliable sealing, and consistent high-pressure fuel delivery across demanding industrial duty cycles. Cross-referenced under 196-1401 and CAT1961401, it is a dependable solution for operators seeking long service intervals and stable engine performance.

Constructed from corrosion-resistant alloy materials with enhanced wear resistance, the injector is optimized for compatibility with high-pressure diesel fuel systems used in 3412B and 3412C power units. Typical applications include diesel generator sets, marine propulsion, tug boats, offshore support vessels, mining equipment, oilfield drilling rigs, industrial pumps, compressor stations, and construction machinery. Its industrial-grade build supports continuous operation in North America, South America, Europe, the Middle East, Africa, Southeast Asia, Australia, and Central Asia markets.

Installation requires disconnecting the fuel supply, removing the old injector, inspecting the cylinder head bore, replacing sealing components, and tightening to specified torque before bleeding the fuel system. For optimal service life, use clean diesel fuel, replace filters regularly, and monitor exhaust smoke and consumption trends. Common symptoms such as black smoke, white smoke, or power loss often indicate worn nozzles, poor atomization, or fuel contamination—conditions this precision-engineered injector is designed to resolve reliably.
