57777286 Ingersoll Rand OEM Drive Coupler

The 57777286 Ingersoll Rand OEM Drive Coupler is an original equipment coupling specified for select Ingersoll Rand portable air compressor models. This coupling provides the torsionally flexible connection between the engine and airend, using a Reich Arcusaflex-style elastomeric element to dampen vibration and transmit torque smoothly.

IR portable compressors rely on properly matched drive couplers to maintain reliable air delivery in demanding field conditions. The 57777286 is designed for the specific torque capacity, vibration characteristics, and shaft configuration of its target compressor models. Using the exact OEM part number ensures the coupling’s stiffness and damping properties match the drivetrain requirements.

This is a direct factory replacement. During installation, clean all shaft surfaces, inspect hubs and keyways for wear, and follow the alignment procedure in the compressor service manual. Run the unit through a complete warm-up and load cycle to verify smooth operation before releasing for service.
