The C7 fuel injector 10R-4764 is engineered as an OE-style replacement injector GP specifically calibrated for C7 diesel engines produced between 2004 and 2009. Built to match the original injector geometry, nozzle spray pattern, and solenoid response characteristics, this unit restores factory-level fuel delivery, atomization quality, and combustion stability for heavy-duty industrial and on-highway applications. It is also commonly cross-referenced in aftermarket catalogs for C9 engine applications, although C9 fitment must be verified against the original injector number, engine serial number, and machine arrangement number before purchase.
Designed for trucks, buses, excavators, loaders, construction machinery, generator support units, mining equipment, and agricultural support equipment, this injector supports engine performance recovery across a wide range of -powered platforms. Possible equipment references include 324D, 325D, 329D, 336, and 336D machines, with final fitment confirmed through the original injector part number and engine serial number. The unit carries global part-number recognition through cross references including 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, allowing distributors, fleet operators, and diesel workshops to streamline inventory and sourcing.
To maximize service life, use clean diesel fuel, replace the fuel filter on schedule, drain the water separator regularly, and inspect electrical connectors and harness routing for damage. Monitor engine oil for fuel dilution and observe exhaust smoke condition as early indicators of injector imbalance. Common failure symptoms such as hard starting, rough idle, black or white smoke, low power, high fuel consumption, engine misfire, injector knock, high exhaust temperature, and no-start conditions often trace back to nozzle blockage, internal wear, seal failure, or fuel contamination. Regular engine diagnostics can identify injector imbalance before severe engine damage occurs, supporting reliable operation in demanding B2B and industrial environments.
