Engineered for heavy-duty fuel delivery, the CAT C9 Series Diesel Fuel Injector 577-7633 (compact number 5777633) is an industrial-grade injector assembly built for Caterpillar C9 engine platforms. Its primary function is to meter, atomize, and deliver diesel fuel into the combustion chamber at the correct timing and quantity, supporting the machine's overall fuel management as described in Caterpillar's official parts documentation for the related injector group 557-7633.
This injector is widely cross-referenced in the aftermarket under 557-7633, 5577633, 20R-8968, 20R8968, 20R-8064, 20R8064, 235-5261, 10R-7222, 387-9438, 328-2577, 20R-9433, and 10R-4764, giving procurement teams multiple search and matching options. Because CAT injector compatibility can vary by engine serial number, machine configuration, emissions system, and ECM calibration, buyers should confirm the engine serial number, injector tag number, machine model, engine arrangement number, and ECM calibration before ordering.
Application coverage includes CAT C9 industrial engines and C9 machine engines installed in excavators (330D, 336D, 336D2, 340D2), motor graders (140M, 160M, 14M), wheel tractor scrapers (627G, 637G), compactors (814F, 815F, 816F), truck engines, and other construction, mining, and power equipment; selected C9.3 references apply only where verified by serial number. Condition options span new, aftermarket replacement, remanufactured, rebuilt, original type, or OEM equivalent depending on the supply channel, making this injector a practical sourcing choice for diesel repair shops, fleet operators, parts wholesalers, and engine rebuild centers.
