The 254-4330 diesel fuel injector is a heavy-duty replacement component engineered for the Caterpillar C9 engine family, covering both CAT C9 and C9 ACERT configurations. Depending on engine arrangement, it operates within a HEUI (Hydraulic Electronic Unit Injector) fuel system, where it meters, pressurizes, atomizes, and injects diesel fuel directly into the combustion chamber. The injector installs in the cylinder head injector bore and is available in new, aftermarket replacement, remanufactured, rebuilt, and OEM-standard condition options.
This injector is designed for the CAT C9, an inline 6-cylinder diesel engine with a displacement of approximately 8.8 liters; C9 ACERT well-service ratings are publicly listed around 205–280 bkW / 205–375 bhp at 2200 rpm, depending on configuration. Typical equipment applications include CAT 330D, 336D, 336D L, and 340D excavators, as well as other C9-powered construction, industrial, and oilfield machinery. Common cross and related numbers include 2544330, 254-4339, 2544339, 254-4340, 2544340, and CA2544330.
For B2B buyers—including excavator repair shops, diesel engine rebuilders, fleet maintenance companies, parts distributors, and mining or construction contractors—the 254-4330 is typically ordered as a single piece, a 6-piece engine set, or in bulk. It is commonly sourced for engine performance restoration, misfire repair, smoke reduction, and fuel consumption correction. Before ordering, always verify the original injector number, engine serial number, and machine arrangement to ensure correct fitment.
