46554923D Doosan OEM Drive Coupler

The 46554923D Doosan OEM Drive Coupler is an original equipment coupling element for Doosan portable rotary screw air compressors. This drive coupler provides the torsional connection between the diesel power source and the compressor airend.

Field service compressors from Doosan run hard in environments where clean air, stable temperatures, and level ground are rare. The coupling element flexes with every engine revolution, absorbing combustion pulses and compensating for the minor misalignment that develops over the life of the machine. When the element deteriorates, vibration energy passes directly into the compressor assembly, increasing noise levels and accelerating internal wear. Operators working near the machine will notice the change in sound signature before performance metrics shift.

This Doosan OEM part installs in the standard mounting arrangement. Remove all fragments of the previous element during service, inspect hub faces under adequate lighting, and hand-rotate the assembly after installation to confirm free movement before starting the engine.
