Perkins original Perkins 0R-8786 Diesel Parts Fuel Injector for 3126B 3126E 3412E C3412 Engine 375 5080 D9N 773D Excavator  original new injector

The Perkins 0R-8786 fuel injector is engineered as a direct OEM replacement for the Perkins 3412, 3412B, and 3412C diesel engine series. Manufactured to meet original Perkins operational specifications, this remanufactured injector assembly delivers precision fuel delivery through optimized nozzle geometry, ensuring accurate fuel distribution and consistent cylinder performance. Authorized OE numbers 0R-8786, 4P9830, and 8N7005 confirm full compatibility with the Perkins 3412 platform, allowing seamless interchange across the supported engine variants without modification.

Built for severe-duty industrial applications, the 0R-8786 injector features high-strength alloy construction and industrial-grade sealing components designed to withstand corrosive marine environments, continuous-duty operation, and high-load conditions. Enhanced combustion efficiency promotes complete fuel burn, supporting stable power output and reduced exhaust emissions. The mechanical injection design provides reliable atomization for engines deployed in power generation systems, marine propulsion vessels, mining haul trucks, drilling equipment, oil and gas well service units, industrial pump drives, and stationary engine installations.

Cross reference numbers 0R8786, 4P-9830, and 8N-7005 allow procurement and service teams to source a verified replacement part through global Perkins distribution networks. Installation should follow the Perkins service manual torque values with new sealing washers, followed by fuel system bleeding and injector timing verification. Routine maintenance—including scheduled fuel filter replacement, water separator draining, injector balance testing, and exhaust condition monitoring—ensures extended service life and OEM-level performance throughout the operational lifecycle of the Perkins 3412 engine family.
