237-4734 20R-4007 Turbocharger for 3054C Diesel Engine 312D2 Excavator

The 237-4734 / 20R-4007 Turbocharger is a replacement diesel engine turbocharger assembly offered for compatible 3054C engine applications, including selected 312D2 excavator configurations.

As an important component of a turbocharged diesel engine, the turbocharger uses exhaust gas energy to drive a turbine wheel, which powers a compressor wheel to supply compressed intake air to the engine.

By increasing the amount of air available for combustion, a properly functioning turbocharger helps the engine achieve its designed power output and operating performance.

The turbocharger features a silver-colored compressor housing, cast-metal turbine housing, intake and exhaust connection ports, mounting flange, and an external wastegate actuator assembly.

Designed for diesel engine maintenance and turbocharger replacement applications, this unit provides a replacement option for compatible construction machinery engines requiring the specified turbocharger configuration.

JISION supplies excavator turbochargers, diesel engine replacement parts, and construction machinery components to equipment owners, repair workshops, construction contractors, and international spare parts distributors.
