original 20R-3477 Diesel Fuel Injector Common Rail Injector for 3512B 3516B 3512C 3516C Engine 5130B 5230B Excavator Replacement for OEM 20R3477 original new injector

Engineered for demanding heavy-duty diesel applications, this 20R-3477 fuel injector is manufactured to OEM-level standards for the . 3512B engine platform. Constructed from hardened alloy steel with precision-machined internal components, the injector delivers accurate fuel metering under high-pressure operating conditions typical of industrial, marine, and mining power units. Each unit is flow-tested to ensure consistent atomization, stable combustion, and reduced vibration across the full load range.

This injector serves as a direct replacement for OE 20R-3477 and cross references including 10R-2106, 10R-2116, 328-9002, 330-0402, 249-0713, 387-9433, 522-5638, 20R3477RX, and 10R2106RX. It fits . 3512B, 3512B HD, 3512B Marine, 3512B Generator, 3512B Offshore, 3512B Power Module, and related . 3512 industrial, generator set, marine propulsion, and petroleum engine configurations. Protective surface treatment provides corrosion resistance for offshore and coastal service environments.

Typical global applications cover copper and gold mining fleets, oilfield and petrochemical operations, utility power stations, data center standby generators, marine transportation, and remote industrial infrastructure across North America, South America, Europe, the Middle East, Africa, and Asia-Pacific. Installation requires fuel supply isolation, careful bore inspection, new sealing washer fitment, OEM torque compliance, and complete fuel system bleeding. Backed by a 12-month warranty, this component supports long service intervals and reliable continuous-duty performance.
