52326568 Ingersoll Rand OEM Drive Coupler

The 52326568 Ingersoll Rand OEM Drive Coupler is an original equipment coupling for Ingersoll Rand DM-series blasthole drilling rigs including the DM-M3, DM-45, DM-50, and DM-L platforms. This coupler connects the deck engine to the onboard rotary screw air compressor that powers downhole drilling operations.

IR DM-series rigs are workhorses in surface mining and quarry blasting operations, running Cummins or Caterpillar diesel engines paired with high-output air compressors rated at 750 to 1050+ cfm. The drive coupler absorbs torsional spikes during engine acceleration and load changes while compensating for minor shaft misalignment inherent in heavy tracked equipment. Failed couplers produce excessive frame vibration that accelerates wear on compressor bearings, engine mounts, and the transfer case.

The 52326568 is a direct OEM replacement sized for DM-series applications. Clean both shaft faces thoroughly during removal, check hub keyways for deformation, and align to factory specifications before torquing hardware.
