Perkins original Perkins 0R-8473 Fuel Injector Replacement for 3114 3116 Engine 320B E200B Wheel Excavator 127-8216 0R8473 new injector original new injector

Engineered as a direct OE cross reference for Perkins 3114 and 3116 mechanical unit injector diesel engines, this remanufactured fuel injector carries the primary authorized OE number 0R-8473 alongside a complete interchange set including 127-8213, 101-8673, 0R-4374, 0R-3382, and 4P-1734. The mechanical unit injector (MUI) configuration is purpose-built for legacy Perkins diesel systems and is not intended for common rail applications, making it a reliable match for engine serial numbers and injector part numbers across the Perkins 3116 series.

The injector is built around an 8mm diameter nozzle with a dual scroll design that mounts directly to the engine cylinder head, supporting stable injection timing, balanced cylinder-to-cylinder fuel delivery, and consistent spray atomization. It helps reduce black smoke, incomplete combustion, and excessive exhaust temperature, while improving cold starting, acceleration response, and fuel economy under load. The dual scroll spray pattern also contributes to protection against piston crown overheating caused by poor atomization.

Suitable for B2B buyers, repair workshops, equipment owners, and diesel parts distributors, this Perkins 3116 reman replacement injector addresses common fault symptoms such as hard starting, white or black smoke, rough idle, engine knock, low power, high fuel consumption, fuel dilution in oil, misfire, low injection pressure, leakage, poor atomization, clogged nozzle holes, cylinder imbalance, and incorrect fuel delivery. Recommended practices include using clean diesel fuel, replacing fuel filters at service intervals, draining water separators, avoiding low fuel levels, checking for air ingress, inspecting return fuel flow, testing spray pattern during overhaul, replacing seals at reinstallation, and storing spare injectors in sealed packaging away from moisture and dust.
