2635834787 Atlas Copco OEM Drive Coupler

The 2635834787 Atlas Copco OEM Drive Coupler is a coupling for Atlas Copco portable compressor and heavy equipment platforms.

This coupling serves the engine-to-driven-component connection in select Atlas Copco machines, using a Lord Dynaflex-style elastomeric element to absorb torsional vibration from the diesel engine. Atlas Copco specifies these couplings for their larger portable compressors and construction-class equipment where sustained high-torque operation demands reliable vibration isolation.

The 2635834787 is a direct factory replacement. Confirm this part number against your Atlas Copco machine’s parts documentation. During installation, follow the manufacturer’s alignment and torque procedures, inspect all mounting hardware, and verify smooth operation after startup.
