54755087 Ingersoll Rand OEM Drive Coupler

The 54755087 Ingersoll Rand OEM Drive Coupler is an original equipment coupling used across a broad range of Ingersoll Rand and Doosan portable air compressors, from compact jobsite units through mid-range models. Compatible platforms include the P105WJD, P125WJD, P130WJD, P160WJD, P175WJD, P185WJD, XP185WJD, P250WJD, P260WIR, P375, and VHP825WCU among others.

This coupler’s wide application range reflects a shared driveline architecture across multiple IR/Doosan portable compressor platforms. The coupling provides the flexible connection between the engine and airend, isolating torsional vibration and accommodating minor shaft misalignment. In portable compressor service – where machines are transported frequently and operate across varying loads and ambient conditions – this vibration isolation is essential for protecting airend bearings and seals.

The 54755087 is a direct OEM replacement. Verify your compressor model and confirm the part number against the service manual before ordering. During installation, clean all shaft surfaces, inspect hub condition, and align per factory specifications. Replace associated hardware if worn.
