The CAT 177-4752 heavy-duty diesel fuel injector is a fuel injection component designed for Caterpillar 3126 Series engine platforms, compatible with 3126B, 3126E industrial and truck engine variants. Searchable by primary OE number 177-4752 (compact format 1774752), it matches cross-reference numbers 10R-1257, 178-6342, and PAI 390078X to streamline parts sourcing. It fits broad Caterpillar heavy equipment: D5N/D6N track-type tractors, 953C/963C track loaders, 120H/135H motor graders, 938G II wheel loaders, IT38G II integrated toolcarriers, and 561N pipelayers.
Engineered for demanding industrial conditions, the 177-4752 injector controls diesel delivery into the combustion chamber by metering exact fuel quantities and releasing fuel at calibrated timing aligned with engine demands. It converts pressurized diesel into a controlled spray pattern to support stable atomization, improve combustion efficiency, reduce incomplete burn, maintain consistent engine power, and preserve optimal fuel economy. Its OE-matched direct-replacement design supports proper calibration and cylinder balance across compatible configurations.
This injector supports diverse professional B2B use cases, including construction and mining fleet maintenance, diesel engine repair, construction machinery parts distribution, remanufactured engine rebuilding, and aftermarket injection system replacement. Buyers should verify fitment via engine serial number, fuel system configuration, equipment model, and existing injector number before purchase, as calibration and control strategies vary across specific machine applications.
