The 46554923 Ingersoll Rand OEM Drive Coupler is an OEM elastomeric coupling for Ingersoll Rand portable air compressor models. This coupler transmits engine power to the compressor airend while providing the flexible connection needed to protect both components from torsional shock.
IR portable compressors are among the most widely used towable units in the contractor and rental market. These machines run across a broad range of ambient temperatures and altitudes, and the drive coupler must perform consistently regardless of conditions. The elastomeric element degrades faster in high-heat environments and on machines that sit idle for extended periods between uses, as the rubber loses flexibility without regular cycling. Preventive replacement during scheduled maintenance avoids the risk of a field failure that shuts down an entire jobsite.
This factory part installs in the original position with no modifications. Clean all mounting surfaces, verify hub condition, and ensure proper engagement before starting the engine. Check for abnormal vibration during the first few minutes of loaded operation.
