46765545D Doosan OEM Drive Coupler

The 46765545D Doosan OEM Drive Coupler is a coupling for Doosan portable air compressor platforms. This coupling provides the engine-to-airend connection in select Doosan portable compressor models, using a Reich Arcusaflex-style elastomeric element for torsional vibration isolation.

Doosan Portable Power compressors are built for construction and industrial jobsite use, with features designed for durability and serviceability in harsh environments. The drive coupler absorbs the constant torsional vibration from the diesel engine while transmitting torque smoothly to the compressor airend. When the coupler element deteriorates, vibration increases throughout the machine, accelerating wear on bearings, seals, and the airend itself.

The 46765545D is a direct factory replacement for the Doosan-numbered coupling. During installation, clean all shaft surfaces, inspect hubs for wear, and align per Doosan’s service procedure. This coupling has multiple hub options – verify your configuration before ordering.
