2651957751 Atlas Copco OEM Drive Coupler

The 2651957751 Atlas Copco OEM Rubber Element is a coupling element for Atlas Copco portable compressor and drilling equipment platforms. This is the replaceable elastomeric insert for the drive coupling, providing torsional damping between the engine and compressor airend in select Atlas Copco portable models.

Atlas Copco portable compressors use Reich Arcusaflex-style couplings as original equipment. The rubber element is the wear component that degrades over time from torsional fatigue, heat cycling, and environmental exposure. Replacing just the element is standard maintenance when the metal hubs remain in good condition, restoring the coupling’s vibration damping at a fraction of the cost of a complete assembly.

The 2651957751 is a direct OEM replacement element. During replacement, inspect both hubs for scoring, corrosion, or dimensional wear before installing the new element. Clean all surfaces and reassemble per Atlas Copco’s service procedure. Verify vibration levels after startup.
