47479775 Case OEM Coupling

The 47479775 Case OEM Drive Coupler is a coupling specified for select Case construction and industrial equipment. This Stromag Periflex-style disc coupling connects the diesel engine flywheel to the driven component, providing torsional damping that protects the drivetrain from engine firing-pulse vibration.

Case equipment powered by diesel engines requires effective torsional vibration control to protect gearboxes, pumps, and other driven components from the cyclic forces generated by piston engines. The Periflex VN-style disc coupling used in this application features a vulcanized elastomer element bonded to a steel angular ring, creating a torsionally flexible connection with linear spring characteristics. This design is specifically engineered for diesel engine drives.

The 47479775 is a direct OEM replacement. During installation, bolt the coupling’s connection ring to the engine flywheel per the manufacturer’s torque specification. Ensure the disc tire engages the connection ring over its full width. Follow the equipment service manual for alignment and spacing requirements.
