original 0R-3580 Diesel Engine Fuel Injector for 3114 3116 3126 Excavator E320B E322B E325B Mechanical Fuel Injector Replacement for OEM 127-8222 original new injector

Engineered as a precision-grade fuel delivery solution for the . 3116 engine platform, this diesel fuel injector (OE 0R-3580) delivers dependable atomization performance in demanding industrial, marine, mining, and power generation environments. The unit is fully interchangeable with cross references 127-8220, 127-8222, 107-7734, 107-7773, 9Y-4982, 4P-2995, 0R0471, 0R8467, and 0R8633, and is compatible with the . 3114 (4-cylinder, 6.6L) and . 3116, 3116B, and 3116C (6-cylinder, 10.3L) engine series.

Manufactured using CNC precision grinding technology, the injector body and nozzle assembly are produced from hardened alloy steel to ensure superior wear resistance under sustained high-pressure operation. A multi-hole nozzle configuration optimizes fuel atomization for improved combustion efficiency, lower emissions, and consistent power output under heavy load conditions. Surface treatment technology provides corrosion protection, extending service intervals in humid, saline, and particulate-heavy operating environments typical of construction, mining, and marine applications.

Installation follows standard OEM procedure: disconnect the battery, remove fuel lines, extract the old injector, inspect the injector bore, fit new sealing components, install and torque the injector to specification, reconnect the fuel system, bleed trapped air, then start the engine and verify operation while checking for leaks. Backed by strict OEM-equivalent quality control, this 0R-3580 injector offers fleet operators, OEM service centers, and industrial distributors a reliable, cost-effective replacement component.
