The Perkins C9 Fuel Injector 557-7634 is an OEM original HEUI unit injector engineered for the Perkins C9 and C9 ACERT diesel engine platforms, with a displacement of 8.8 liters. The part number 557-7634 serves as the primary OE reference, with extensive cross compatibility including 328-2574, 328-2580, 235-2888, 236-0962, 267-9710, 267-9734, 293-4071, 459-8473, 10R-7221, 10R-7222, 20R-8060, 20R-8065, 20R-1917, 20R-8968, 387-9433, 387-9434, and 254-4330, covering both replacement and remanufactured part lines used across the Perkins heavy equipment range.
Within the HEUI fuel system, the injector receives electronic commands from the engine control module, and high-pressure engine oil drives the intensifier piston to generate the injection pressure required for complete fuel atomization. This working principle delivers OEM-calibrated flow rates, stable injection timing, and efficient combustion, supporting reliable power output under demanding load conditions. The injector body is built with corrosion-resistant materials and heavy-duty internal components to ensure long service life in harsh operating environments.
This 557-7634 injector is widely applied in construction, mining, marine, and power generation equipment, including Perkins 330C, 330D, and 336D excavators, 950H, 962H, and 966H wheel loaders, 730 and 740 articulated trucks, C9 generator sets, and marine power units. The product meets OEM quality standards and is backed by a 12-month warranty. Installation recommendations include using clean fuel, replacing sealing washers, inspecting fuel rail components, performing injector coding if applicable, and verifying fuel pressure after installation.
