Reliable fuel delivery is the foundation of every Cat C9-powered machine on the jobsite, and the 387-9433 fuel injector is engineered to provide exactly that. Designed for Caterpillar C9 and C9 ACERT diesel engines, this heavy-duty injector serves excavators, mining machines, industrial power units, petroleum equipment, forestry machines, compactors, motor graders, and wheel tractor scrapers. For sourcing flexibility, it is widely cross-referenced as 10R-7222, 20R-1917, 20R-8064, 20R-8968, 557-7633, 553-2592, 293-4072, 328-2574, 267-3360, and 254-4339.
In operation, the injector delivers precisely metered diesel into the combustion chamber at the correct timing, quantity, and spray pattern. Fine atomization improves air-fuel mixing, supports cleaner combustion, stabilizes idle quality, and helps the engine maintain torque under heavy load. Built to withstand high vibration, high temperature, variable load, and contaminated jobsite conditions, the 387-9433 helps reduce rough idle, exhaust smoke, hard starting, and fuel consumption—practical advantages for distributors, rebuilders, and fleet maintenance programs.
Typical machine applications include Caterpillar 330D, 330D L, 336D, 336D L, 336D2, 340D L, and 340D2 L excavators, plus E330D, E336D, and E360D models; extended supplier listings also cover 637-series scrapers, 815F II and 816F II compactors, and 140M/160M motor graders. Because fitment varies by machine configuration, Caterpillar recommends verifying compatibility by engine serial number, machine serial number, arrangement number, and the existing injector number before shipment. Send us your serial details for fast fitment confirmation and quotation.
