original 328-2573 Diesel Engine Fuel Injector for C9 Engine Excavator 330D E330D 336 D6R D7R D6T Replacement for OEM 3282573 20R-8063 267-3361 293-4072 original new injector

Engineered for demanding heavy-duty operations, the 328-2573 Fuel Injector is a precision-manufactured diesel injection component designed to deliver OEM-level performance across a wide range of C9 series engines. This injector supports C9, C9 ACERT, C9 Industrial, C9 Generator, and C9 Marine engine platforms, offering reliable electronic unit injection performance for excavators, wheel loaders, bulldozers, graders, mining trucks, drilling equipment, diesel generator sets, commercial vessels, and industrial power packs. Cross-reference numbers include 328-2573, 3282573, and 328 2573 for straightforward interchange identification.

The 328-2573 injector is built to achieve high precision fuel metering, superior spray pattern control, and enhanced combustion efficiency. Key benefits include reduced fuel consumption, lower exhaust emissions, increased horsepower, faster throttle response, and extended operating lifespan. Excellent thermal resistance and robust internal construction ensure dependable performance under continuous high-load duty cycles typical of construction, mining, marine propulsion, and prime-power generation applications. Its OEM-equivalent design supports direct fitment without engine modification.

Recommended installation involves disconnecting battery power, removing the valve cover and old injector assembly, inspecting the injector bore, fitting new seals and O-rings, torquing to OEM specifications, reconnecting the electrical harness, priming the fuel system, and performing engine diagnostic verification. To prevent common issues such as fuel leakage, nozzle wear, solenoid malfunction, carbon buildup, and contamination-related failures, operators should use clean diesel fuel, replace filters regularly, drain water separators, and monitor fuel pressure through periodic diagnostics.
