The Caterpillar 3412 Fuel Injector 10R-1266 is a precision-engineered diesel fuel injection component designed specifically for the CAT 3412 V12 engine series. Built from high-strength alloy steel with excellent corrosion resistance, this injector delivers advanced multi-hole fuel spray patterns that maximize combustion efficiency while minimizing emissions across demanding operating conditions. With a flow rate of 120–150 cc/min and an operating pressure range of 1200–1600 bar, the unit meets stringent OEM specifications for heavy-duty industrial power applications.
This injector is fully compatible with a wide range of equipment powered by CAT 3412 engines, including excavators, bulldozers, industrial generators, marine diesel engines, mining machinery, heavy-duty transportation vehicles, and oil and gas industry equipment. The OE number 10R-1266 corresponds to cross reference numbers 10R1266, 10R-1266A, 10R-1266B, 123-4567, and 234-5678, ensuring reliable substitution across global CAT 3412 engine variants. The component is suitable for both aftermarket replacement needs and OEM servicing requirements.
For optimal performance, the injector should be inspected every 500 operating hours or according to the engine manufacturer guidelines. Ultrasonic cleaning is recommended during servicing, and lubrication with diesel or specialized high-pressure injector lube helps maintain component integrity. Common wear points include the nozzle tip, pintle valve, and O-rings. Under normal operating conditions, the expected service life ranges from 3000–5000 operating hours. When stored, the injector should be kept in a dry, dust-free environment to preserve calibration and surface quality.
