original 328-2577 Common Rail Fuel Injector 3282577 10R-4764 20R-8060 387-9438 Diesel Engine Injector for C7 C9 330D 336D Excavator Parts original new injector

Engineered for heavy-duty diesel applications, the 328-2577 Fuel Injector Assembly is a direct replacement Injector GP built for the C9 series engine platform. It fits excavators including 330D, 336D, E330D, E336D and E340D, and is cross-referenced under 3282577 and 20R-8060 for streamlined inventory indexing across distributor and workshop channels.

The injector delivers precision fuel metering and fine diesel atomization, supporting engine power recovery, fuel economy and emission control after injector failure. Its durable structure withstands demanding construction, mining and earthmoving duty cycles, while the direct replacement design allows workshop-friendly installation with standard OEM procedures. Typical fault symptoms it addresses include hard starting, rough idle, black or white smoke, engine knock, power loss, misfire, high fuel consumption and diesel dilution in engine oil caused by injector leakage, poor atomization or blockage.

Installation should be carried out by a qualified diesel technician following the OEM service manual: confirm part number, depressurize the fuel system, replace seals, torque to specification, bleed the system and clear fault codes with a compatible diagnostic tool. For long service life, use clean diesel, replace fuel filters on schedule, drain the water separator and keep injectors sealed until fitment. Ideal for retail, wholesale, fleet repair, export trade and distributor supply programs.
