The 2651957736 Atlas Copco OEM Drive Coupler is an OEM coupling for select Atlas Copco portable compressor platforms. This Reich Arcusaflex-style coupling provides the torsionally flexible connection between the diesel engine and compressor airend in Atlas Copco portable machines.
Atlas Copco uses Arcusaflex couplings as original equipment across their portable compressor range. The elastomeric element absorbs engine firing-pulse vibration before it reaches the airend, extending bearing and seal life in machines that run extended hours in demanding field conditions. Element deterioration shows up as increased frame vibration and drivetrain noise during load changes.
The 2651957736 is a direct OEM replacement. Install per Atlas Copco’s alignment procedure.
