Caterpillar original 10R-1279 Common Rail Diesel Fuel Injector for CAT 3512B 3516B, Replacement for OEM 10R-7238, 10R-1275, 20R-3477, Diesel Car and Machinery Engine Parts original new injector

Precision-engineered for demanding Caterpillar 3500 Series diesel engine platforms, the 10R-1279 mechanical fuel injector is a core fuel system component manufactured to strict OEM equivalent specifications. It is designed to fit compatible CAT engine models including 3512B, 3516B, 3508B, 3512C, 3516C and 3508C, with cross-reference support for part numbers 170-5185, 212-3467 and 249-0713 for seamless part matching during scheduled maintenance and engine overhauls.

Built with high-strength alloy steel and corrosion-resistant materials, the 10R-1279 features a hardened nozzle assembly, precision-machined internal components and high-pressure operating capability, with every unit undergoing factory flow testing and OEM calibration before release. These design elements deliver precisely metered, finely atomized fuel to optimize combustion efficiency, reduce fuel consumption and exhaust emissions, minimize carbon deposits, improve cold-start performance, and maintain consistent engine power output under heavy load conditions.

Suitable for a wide range of industrial operational scenarios, the injector supports power generation facilities, marine propulsion systems, mining operations, oil and gas extraction equipment, and heavy construction machinery. It comes with a 12-month warranty for global export supply, and aligns with official Caterpillar installation and maintenance protocols to support long-term reliable engine performance.
