Perkins original  10R-4764 Diesel Fuel Injector Replacement for OEM 387-9438 293-4067 fits C9 330D 336D Excavator Generator  original new injector

The Perkins C7 Series Fuel Injector 10R-4764 is an OE-style replacement injector built for Perkins C7 diesel engines used in truck, bus, excavator, loader, construction machinery, and industrial equipment from 2004 through 2009. It is also cross-referenced in aftermarket catalogs for Perkins C9 applications, so C9 fitment should always be confirmed by part number, original injector number, engine serial number, and machine arrangement number before ordering. Common equipment references include Perkins 324D, 325D, 329D, 336, and 336D, and final fitment must be validated using the original injector part number and engine serial number. Dimensions are 14.2 inches in length and 5.3 inches in height, matching original equipment specifications for direct installation.

This injector is designed to deliver precise fuel metering, stable atomization, and reliable combustion, supporting engine performance recovery, reduced exhaust smoke, and proper emission output. The heavy-duty construction ensures durability in demanding industrial and heavy equipment environments. It is widely used in fleet repair operations, full engine overhauls, diesel workshop maintenance, and industrial engine parts supply chains where OE-style reliability is required. Regular engine diagnostics are recommended to detect injector imbalance early and prevent further engine damage.

The 10R-4764 cross-references 10R4764, 293-4067, 387-9438, 20R-8060, 328-2577, 245-3516, 245-3517, 245-3518, 240-8063, 245-3416, 295-1408, 295-9166, 20R-8057, and 20R-8067, giving distributors and workshops broad interchange coverage. Common failure symptoms include hard starting, rough idle, black or white smoke, low power, high fuel consumption, engine misfire, injector knock, fuel dilution in engine oil, high exhaust temperature, diagnostic fault codes, and no-start conditions. To maximize service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator, prevent fuel contamination, inspect electrical connectors, monitor engine oil for fuel dilution, and check exhaust smoke condition regularly.
