36851939 Ingersoll Rand OEM Drive Coupler

The 36851939 Ingersoll Rand OEM Drive Coupler is an OEM coupling for Ingersoll Rand portable air compressor platforms. This Lord Dynaflex-style coupling connects the engine to the airend, providing torsional vibration isolation in IR portable compressors used across construction and industrial service.

IR portable compressors with this coupling handle jobsite air supply for pneumatic tools, sandblasting, and general industrial compressed air needs. The coupling absorbs the constant torsional load from the diesel engine while compensating for minor misalignment between the engine and airend. Proactive replacement during scheduled service prevents the downstream bearing and seal damage that occurs when a worn coupling fails to properly dampen vibration.

The 36851939 is a direct OEM replacement. Install per IR’s procedure with proper alignment verification.
