original 0R-8469 Diesel Engine Fuel Injector Nozzle for 3114 3116 Excavator 325 325L Wheel Loader 950F 960F Replacement for OEM 127-8225 7E-8952 original new injector

Engineered as a direct replacement fuel injector for the 3116 diesel engine platform, this assembly carries OE number 0R-8469 and is cross-referenced under 127-8225, CA0R8469, and CA1278225. Multiple part number formats improve searchability for repair shops, engine rebuilders, and parts distributors sourcing components for heavy-duty diesel service. Some aftermarket suppliers also list 3126 compatibility, though fitment should always be verified by the original injector number, engine serial number, and machine arrangement.

The injector is designed for precision fuel delivery, stable atomization, and reliable sealing under high-pressure operating conditions. It supports consistent combustion performance in construction equipment, medium-duty trucks, industrial power units, agricultural machinery, generator sets, and marine auxiliary engines. Heavy-duty construction targets long service life in demanding fleet, rental, and industrial maintenance environments, where downtime cost and repeatable performance are critical procurement considerations for B2B buyers.

Common injector-related symptoms include hard starting, rough idle, black or white smoke, knocking, low power, high fuel consumption, misfire, and fuel dilution in engine oil. Before installation, confirm the injector part number, engine model, and engine serial number, clean the fuel system, and inspect lines, seals, and washers. Apply the correct service manual torque, bleed the fuel system, and test for leakage, idle stability, and abnormal noise after fitment.
