The Caterpillar 3512B fuel injector 392-0212 is an original OEM diesel fuel injector assembly engineered for the CAT 3500 series engine platform. Manufactured using CNC-machined hardened alloy steel components, this injector is designed for continuous industrial duty cycles and high-pressure operation. It maintains original Caterpillar fuel delivery specifications, ensuring consistent injection timing and precise atomization of diesel fuel into microscopic droplets for complete combustion across demanding operating environments.

This injector is compatible with CAT 3506, 3506B, 3508, 3508B, 3512, 3512B, 3512C, 3516, 3516B, 3524, and 3524B diesel engines, primarily used on the CAT 3512B platform. It carries cross references including 20R-0848, 10R-1275, 0R-8215, 250-1312, 373-4087, and 229-0192, allowing flexible interchange for replacement and remanufacturing requirements. A special surface treatment provides corrosion resistance against fuel contamination and moisture, supporting extended service life in power generation, marine propulsion, mining, oil and gas, and large-scale industrial machinery applications.

The 392-0212 injector assembly optimizes fuel economy, improves combustion efficiency, and supports reduced emissions for cleaner operation. It receives pressurized diesel fuel, controls injection timing precisely, and maintains stable engine output under heavy load conditions. Warranty coverage extends to 12 months. Recommended maintenance includes cleaning the injector bore and replacing sealing washers before installation, bleeding the fuel system after installation, inspecting fuel filters and pressure every 500 hours, and performing spray pattern analysis and fuel flow verification every 1000 hours.
