original 0R-4374 Diesel Fuel Pump Injector 107-1230 0R-8479 127-8205 for 3116 C3116 Engine E320B E325B Excavator new injector original new injector

Engineered exclusively for the 3116 diesel platform, the 0R-4374 fuel injector is precision-manufactured to match the original equipment specifications of the 3116 direct injection system. Its CNC-machined components and precision-calibrated nozzle ensure a consistent spray pattern and stable fuel delivery, supporting improved combustion efficiency, lower fuel consumption, and reduced black smoke emissions across a wide range of operating conditions. The hardened steel body, corrosion-resistant coating, and high-temperature construction deliver the long service life required for heavy-duty industrial use.

This injector is fully compatible with 3116 engines deployed in construction equipment, heavy duty trucks, generator sets, marine vessels, and mining machinery. Each unit is OEM flow tested to guarantee consistent performance and tight tolerance internal components, providing enhanced engine response and dependable operation in harsh environments. The 0R-4374 cross-references with 137-4374, allowing straightforward replacement for existing fuel system components without modification.

To maintain optimal injector performance and protect the 3116 fuel system, operators should use high-quality diesel fuel, replace fuel filters at regular intervals, monitor fuel pressure, and prevent water contamination. Prolonged engine idling should be avoided, and periodic injector testing along with professional calibration after installation is recommended. Backed by a 12-month warranty, the 0R-4374 offers a reliable, OEM-equivalent injection solution for global 3116 applications.
