Caterpillar original 180-7431 Common Rail Diesel Fuel Injector Repair Kit Assembly Replacement for 3126 10R0782 131-7150 177-4752 178-0199 original new injector

The Caterpillar 180-7431 fuel injector is a genuine OEM electronic unit injector engineered for the CAT 3126, 3126B, and 3126E diesel engine series, as well as selected Caterpillar C7 applications. As an authentic Caterpillar component manufactured to strict OEM tolerance standards, the 1807431 injector delivers precise fuel metering and stable injection performance demanded by heavy duty industrial operations. It serves as a direct replacement for cross reference part numbers 10R-0781, 10R0781, 0R-8479, and 0R8479, allowing seamless integration into existing CAT fuel systems without modification. The 180-7431 is constructed from high strength alloy steel with corrosion resistant properties, ensuring long term durability under extreme operating conditions.

This electronic fuel injection component is specifically designed for cylinder head installation and operates through advanced electronic control compatibility, working in synchronization with the engine control module to optimize combustion efficiency. The precision machined nozzle produces an optimized spray pattern that promotes complete fuel atomization, reducing emissions while maximizing power output. Built with heavy duty industrial design principles, the 180-7431 injector withstands the high pressure demands of modern diesel engines and maintains consistent performance across variable load conditions. Ultra Low Sulfur Diesel compatibility further extends its operational flexibility across global markets where strict fuel regulations apply.

The 180-7431 fuel injector is widely applied across heavy duty trucks, commercial buses, generator sets, construction equipment, marine applications, agricultural equipment, and industrial power units. To ensure proper function and extended service life, installation should be performed in a clean environment with the injector bore inspected beforehand, sealing components replaced as needed, and Caterpillar torque specifications strictly followed. Post-installation engine diagnostics, regular fuel filter replacement, prevention of water contamination, and periodic injector testing are recommended to maintain peak performance. This genuine Caterpillar 3126 series injector represents the ideal combination of original equipment reliability, precision engineering, and long term operational value for professional B2B buyers and fleet maintenance operations.
