46587479 Doosan OEM Drive Coupler

The 46587479 Doosan OEM Drive Coupler is an original equipment coupling for Doosan portable air compressors. This elastomeric coupler connects the diesel engine to the compressor airend, providing torsional vibration isolation and smooth torque transmission during operation.

Doosan portable compressors serve construction, pipeline, sandblasting, and general industrial applications where reliable compressed air delivery is critical. The drive coupler in these machines operates under constant load, absorbing engine firing pulses while compensating for thermal expansion and minor shaft misalignment. Over time, the rubber element wears from heat cycling and continuous flexing, leading to increased vibration at the frame, audible drivetrain noise, and eventually reduced compressor output stability.

The 46587479 drops directly into the factory mounting position on compatible Doosan portable units. During replacement, inspect both hubs for wear, clean shaft surfaces thoroughly, and verify alignment before torquing fasteners to specification.
