original 180-7431 Diesel Fuel Injector Assembly for 3126 Engine Common Rail Injector Nozzle Repair Kit 1807431 10R0782 177-4752 178-0199 Replacement original new injector

Engineered as a direct replacement for the 180-7431 Electronic Unit Injector, this precision-manufactured fuel injection component is purpose-built for 3126, 3126B, and 3126E diesel engines, along with selected C7 applications, industrial power units, marine propulsion engines, and generator set engines. Cross-referenced with 10R-0781 and 0R-8479, the injector delivers consistent atomization and stable fuel delivery, meeting OEM tolerance manufacturing standards for demanding heavy-duty operation.

Constructed from high-strength alloy steel with a precision machined nozzle and corrosion-resistant components, the 180-7431 injector features an optimized spray pattern that supports improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions. Advanced electronic control compatibility ensures seamless integration with the engine's ECM, while heavy-duty industrial design delivers increased engine power, better cold start performance, and enhanced durability. The injector is compatible with Ultra Low Sulfur Diesel (ULSD) and installs directly into the cylinder head position for reliable field service.

Suitable for global B2B applications including heavy-duty trucks, commercial buses, logistics fleets, municipal vehicles, earthmoving equipment, commercial fishing vessels, workboats, passenger ferries, diesel generator sets, emergency backup systems, and agricultural machinery. Recommended installation practices include cleaning the injector bore, replacing sealing components, verifying electronic connectors, and following torque specifications. Diagnostic support includes reading ECM fault codes, checking fuel pressure, performing cylinder cut-out and injector balance tests, and inspecting nozzle condition to ensure long-term operational reliability.
