53173829 Ingersoll Rand OEM Drive Coupler

The 53173829 Ingersoll Rand OEM Drive Coupler is an OEM coupling used on Ingersoll Rand track-mounted blasthole drilling rigs. This part provides the flexible connection between the deck diesel engine and the high-capacity air compressor assembly.

Surface mining drill rigs demand reliable power transfer from engines producing 400 to 600+ horsepower. The drive coupler in these machines handles massive torsional loads while absorbing the vibrational energy that would otherwise travel through the drivetrain and damage downstream components. IR blasthole rigs equipped with HR2-series and similar compressors rated at 900 to 1070 cfm rely on properly functioning couplers to maintain consistent air delivery for efficient drilling cycles.

The 53173829 replaces the original coupler directly with no modifications to the mounting arrangement. Inspect the compressor input shaft seal during replacement, as a failed coupler sometimes allows enough movement to damage the seal face. Follow the IR service manual for alignment procedures specific to your rig model.
