Perkins original  254-4339 Common Rail Diesel Engine Fuel Injector for C9 E330D 330 Excavator 10R7222 387-9434 387-9432 328-2580 328-2576 original new injector

The 254-4339 diesel fuel injector is engineered as an OEM-type replacement for Perkins C9 series engines commonly installed in 330D, E330D, 336, 336D, and E336D excavators, with cross references 2544339 and CA2544339. Built to deliver precision fuel metering, controlled injection timing, and stable atomization, this injector assembly supports reliable combustion, consistent engine response, improved power output, and reduced smoke across demanding construction, quarry, mining, and earthmoving operations.

Constructed for heavy-duty service, the 254-4339 injector features robust internal components, tight sealing surfaces, and a precisely calibrated nozzle that together promote better fuel economy, stable cylinder-to-cylinder performance, and stronger replacement value for fleet maintenance and diesel repair workshops. Every unit undergoes quality inspection before shipment and is supplied in export-ready packaging with bulk supply options, making it suitable for parts distribution and international trade.

Before installation, operators should confirm the engine arrangement number, machine serial number, and original injector number against the official Perkins parts catalog, inspect the fuel filter and fuel lines, and replace all required seals, O-rings, and washers. After installation, follow Perkins torque specifications, perform calibration if required, and check for fuel leaks, abnormal noise, smoke, misfire, and fault codes to ensure optimal injector performance.
