46817246D Doosan OEM Drive Coupler

The 46817246D Doosan OEM Drive Coupler is a factory coupling for Doosan diesel-driven portable air compressors. This part provides the flexible mechanical connection between the engine and compressor airend assembly.

Portable compressors from Doosan are deployed across jobsites ranging from highway construction to utility installation to industrial maintenance. The drive coupler handles the full torque output of the diesel engine while isolating vibration that would otherwise transfer to the compressor bearings and housing. These machines are transported frequently, and the mechanical stress of road travel combined with operational loads accelerates wear on the coupling element. Early symptoms include a noticeable increase in frame vibration and audible rattling during engine speed transitions.

This is a Doosan OEM part built to the original dimensional and material specifications. Remove the old element completely during replacement, check both hub bores for scoring, and confirm proper shaft engagement depth before reassembly.
