2651779031 Atlas Copco OEM Drive Coupler

The 2651779031 Atlas Copco OEM Drive Coupler is an OEM coupling for Atlas Copco portable compressor and equipment platforms. Atlas Copco’s portable compressor range includes units from compact jobsite machines to large production compressors, and this coupling serves the engine-to-airend connection in select models.

The coupling absorbs torsional vibration generated by the diesel engine, protecting the airend bearings and seals from vibratory fatigue. In Atlas Copco compressors running continuous duty on construction and mining support sites, coupler condition has a measurable impact on airend service life and overall machine reliability.

The 2651779031 is a direct factory replacement. Install per Atlas Copco’s service procedure with proper alignment verification.
