Caterpillar original 239-4908 common rail fuel injector for C11 C13 C10 C12 C15 C18 3512 diesel engine construction machinery parts original new injector

The Caterpillar CAT C13 Fuel Injector 239-4908 is an OEM-standard replacement injector assembly engineered for heavy-duty diesel fuel delivery in demanding industrial environments. Built to original factory specifications, this injector delivers precision fuel metering and high pressure resistance, ensuring stable fuel flow and consistent injection timing across a wide range of operating conditions. It is compatible with Caterpillar C13, C13 ACERT, C13 Industrial, C13 Generator Set, C13 Marine Power Unit, and C13 Truck Engine configurations.

Manufactured using precision-machined components and advanced calibration technology, the 239-4908 injector provides OEM flow calibration with a low leakage rate and excellent thermal performance. Enhanced durability and corrosion resistance allow long service life even under extreme duty cycles found in mining trucks, excavators, wheel loaders, bulldozers, motor graders, generator sets, marine power systems, and oilfield power units. This injector serves as a direct interchangeable replacement for cross reference numbers 10R-1273, 253-0616, 328-2574, 387-9433, and 20R-8064.

For optimal performance and longevity, operators should use clean diesel fuel, replace fuel filters regularly, monitor system fuel pressure, inspect for leakage, and follow OEM maintenance schedules. Diagnostic procedures including ECM fault code reading, fuel pressure testing, injector balance testing, leak down testing, cylinder cutout testing, and fuel quality analysis are recommended to ensure reliable operation of the CAT C13 fuel injection system throughout its service life.
