The 51957736 Ingersoll Rand OEM Drive Coupler is a coupling specified for select Ingersoll Rand portable compressor models. This coupling connects the engine output to the compressor airend through a torsionally flexible elastomeric element that isolates vibration and absorbs shock loads.
Portable compressor drive couplers operate under continuous stress – diesel engine vibration, varying load demands, temperature cycling, and the physical jarring of being transported between jobsites. The 51957736 is designed to handle these conditions while maintaining smooth torque delivery. When the coupling element deteriorates, the first signs are increased frame vibration, audible drivetrain noise, or rough operation during load transitions.
This is a direct OEM replacement that matches the factory coupling specification. Install per the compressor service manual with particular attention to shaft alignment and hub spacing. Replace any worn mounting hardware during the changeout.
Stark Industrial Products ships Ingersoll Rand OEM couplers daily to compressor service teams across the country.
