2653173829 Atlas Copco OEM Drive Coupler

The 2653173829 Atlas Copco OEM Drive Coupler is an original equipment coupling specified for Atlas Copco blasthole drilling rigs. This part services the engine-to-compressor connection on Atlas Copco track-mounted drills used in surface mining, quarry operations, and large-scale construction drilling programs.

Atlas Copco blasthole rigs operate in extreme conditions where rock dust, thermal cycling, and sustained high-torque loads are constant. The drive coupler isolates torsional vibration from the diesel power plant while transmitting full engine output to the onboard air compressor. Deterioration of the elastomeric element introduces frame vibration and reduces drilling efficiency as air delivery becomes inconsistent under load.

The 2653173829 is a direct-fit OEM replacement that matches factory hub geometry and elastomer specifications. During installation, verify shaft runout on both the engine and compressor sides, clean all mating surfaces, and torque mounting hardware to Atlas Copco service manual values.
