original 268-9577 Fuel Injector Assembly 10R-7225 328-2585 387-9430 243-4502 269-1839 for C7 Engine 325D new injector original new injector

Engineered exclusively for the C7 and C7 ACERT series, the 268-9577 fuel injector delivers precise compatibility with the 7.2L inline 6-cylinder diesel platform, covering the full 190-360 HP operating range. Its electronic high pressure injection and ACERT emission technology integration ensure the injector matches factory calibration parameters, supporting turbocharged, water-cooled, direct injection systems across excavators, wheel loaders, motor graders, generator sets, marine engines, and industrial power units. The injector is fully interchangeable with OEM references 10R-7675 and 328-2577, guaranteeing drop-in fitment for the C7 engine family without modification.

Manufactured to OEM dimensional accuracy, each unit features micron-level nozzle machining, dynamic flow balancing, and high-pressure calibration testing. Heat-treated internal components, a wear-resistant needle valve, and corrosion-resistant materials provide extended service life under demanding duty cycles found in construction, mining, power generation, and marine applications. Stable fuel atomization, consistent injection timing, and optimized combustion efficiency translate into improved fuel economy, enhanced engine power, reduced exhaust emissions, and better cold start performance for the C7 ACERT powerplant.

Every injector undergoes 100% factory testing including leak testing, flow calibration, pressure verification, spray pattern analysis, and electrical performance validation. Prior to installation, operators should clean the injector bore, inspect seat condition, replace sealing components, apply service torque specifications, install new fuel filters, and bleed the fuel system. Diagnostic procedures such as injector balance testing, cylinder cut-out analysis, fuel pressure checks, ECM scanning, and leak-off testing are recommended to maintain peak C7 engine performance.
