original Fuel Injector 324-5467 Replacement for OEM 364-8024, for heavy duty diesel engine application, 456-3544, 304-3637 for C9.3 Engine Sprayer Excavator Truck original new injector

The erpillar 324-5467 fuel injector is a precision-engineered diesel fuel injection component developed for the C9.3 engine platform. Manufactured to meet or exceed OEM specifiions, this brand-new injector assembly delivers accurate fuel atomization, optimized combustion efficiency, reduced emissions, enhanced power output, and improved fuel economy under demanding industrial operating conditions.

Operating within a high-pressure common rail fuel system, the injector is activated by an electrical signal from the Engine Control Module (ECM), which calculates engine speed, load, air intake volume, fuel demand, and emission requirements before precisely opening the injector needle. The resulting atomized fuel delivery supports improved power output, lower fuel consumption, better cold-start performance, and stable engine operation. The 324-5467 fits erpillar C9.3, C9.3 ACERT, C9.3B, Industrial C9.3, and Generator Set C9.3 engines, and is commonly applied in 336 and 340 excavators, 966 and 972 wheel loaders, motor graders, soil compactors, generator sets, and mining equipment.

Built from high-strength alloy steel, the injector offers OEM-level dimensional accuracy, high-pressure injection capability, corrosion resistance, and long operational life, helping reduce maintenance costs across construction, mining, power generation, agricultural, marine, and industrial appliions. As a direct replacement, it cross-references part numbers 326-4700 and 387-9433; compatibility should always be verified against the engine serial number (ESN) before ordering. For dependable service, use ultra-clean diesel fuel, replace filters regularly, prevent water contamination, and follow erpillar torque specifiions during installation.
