Perkins original Perkins 268-9577 C7 C9 Diesel Common Rail Injector 387-9428 387-9426 241-3239 238-8901 for 324D 329D new injector original new injector

Engineered specifically for the Perkins C7 and C7 ACERT platform, the 268-9577 fuel injector delivers OEM-equivalent performance across a wide range of heavy-duty applications. This genuine replacement injector directly cross-references with 10R-7675, 10R7675, 328-2577, and 3282577, ensuring seamless compatibility with the 7.2L inline 6-cylinder diesel engine rated between 190-360 HP. Built to match original factory specifications, it is suitable for Perkins 320D and 323D excavators, wheel loaders, motor graders, generator sets, industrial power units, and marine propulsion systems operating in construction, mining, power generation, and marine sectors.

Precision manufacturing defines every unit, featuring micron-level nozzle machining, high-pressure calibration, and dynamic flow balancing to ensure stable fuel atomization and consistent injection timing. The injector incorporates heat-treated internal components, a wear-resistant needle valve, and corrosion-resistant materials, extending service life under demanding operating conditions. Each assembly undergoes 100% factory testing including leak testing, flow testing, pressure verification, spray pattern analysis, and electrical performance validation, guaranteeing reliable cold start performance, optimized combustion efficiency, and reduced exhaust emissions across all supported engine configurations.

Proper installation requires cleaning the injector bore, inspecting the injector seat condition, replacing sealing components as needed, applying Perkins service torque specifications, and bleeding the fuel system after installation. For diagnostic evaluation, technicians should perform injector balance tests, cylinder cut-out tests, fuel pressure tests, ECM diagnostic scans, leak-off testing, and visual injector inspection. Routine preventive maintenance—using high-quality diesel fuel, replacing fuel filters at recommended intervals, and monitoring engine fault codes—ensures long-term reliability and sustained engine performance.
