Engineered for the Caterpillar C9 and C9 ACERT diesel platform, the 20R-1259 fuel injector provides an OEM-standard replacement solution for one of CAT's most widely used industrial engines: the inline six-cylinder, 8.8-liter, turbocharged C9 with air-to-air aftercooling and electronic fuel management. Manufactured to OEM-level specifications, it delivers accurate fuel metering and superior atomization, supporting stable combustion performance across construction, mining, power generation, marine, oilfield, and general industrial applications.
Built with CNC-machined components and micron-level tolerances, the injector features premium alloy steel construction with advanced surface treatment for corrosion resistance, high-pressure durability, and thermal stability under severe operating conditions. Under ECM control, the injector opens at precisely calculated timing based on engine load, speed, throttle position, intake air, and coolant temperature data, atomizing diesel into microscopic droplets for faster ignition, more complete combustion, increased horsepower, lower fuel consumption, and reduced emissions. It is designed for long service life in continuous-duty equipment and is backed by a 12-month warranty.
This injector cross-references Caterpillar numbers 237-3300, 236-3300, 10R-4761, 249-0712, and 328-2585, and is compatible with CAT 330D and 336D excavators, 950H and 966H wheel loaders, D6R and D7R dozers, industrial generator sets, and commercial marine engines. It is an ideal OEM-quality replacement solution for fleet maintenance companies, CAT equipment dealers, engine rebuilding workshops, diesel fuel system specialists, and global aftermarket distributors.
