original 7C-2239 Diesel Engine Fuel Injector for 3500A 3508 3512 3516 Common Rail Fuel Injectors Replacement for OEM 7E-6408 9Y-1785 Auto Parts original new injector

Engineered for demanding industrial duty cycles, the 7C-2239 diesel fuel injector is a precision-built replacement component for 3512A series engines and closely related 3512B, 3512C, and 3516 platforms. Manufactured from hardened alloy steel and machined to OEM tolerances, this injector delivers exact form-fit-function performance, ensuring seamless direct fit installation without modification. Its multi-hole nozzle geometry is optimized to atomize diesel at operating pressures of 1800–2200 bar, promoting deeper combustion penetration, cleaner burn, and reduced particulate emissions across continuous heavy-load operation.

Cross-compatibility is a key procurement advantage. The 7C-2239 references directly to 7C2239, 4W-3563, 7C-0345, 10R3053, 9Y-0052, 7E-2269, 0R-0906, 0R-175, 7C-4173, 7C-9576, and 7E-6048, giving fleet operators, MRO buyers, and OEM service centers flexible sourcing options with cost-effective reman and new-build supply channels. The hardened construction provides exceptional resistance to wear, corrosion, and high thermal stress inherent to mining, marine, power generation, and oil & gas applications.

Installation follows a standard workflow: cool the engine, clean injector bore and fuel rail ports, torque to 55–65 Nm using a calibrated wrench, bleed the fuel system, and pressure-test for leaks. Routine inspection for carbon buildup and spray pattern integrity extends service life. Backed by a 12-month warranty, this injector is trusted worldwide for reliable high-pressure fuel delivery.
