The Bard 5070-010 drive pulley is an OEM mechanical component used in Bard 5-ton WERV equipment to transfer motor torque to the belt-driven assembly, helping maintain proper airflow and reliable ventilation performance. A worn, glazed, or out-of-round pulley can contribute to belt slip, vibration, and premature belt wear, so replacing the pulley is a practical fix when servicing the belt drive on compatible WERV units. Because this is a fit-critical part, confirm the exact WERV model and pulley alignment details in your Bard service documentation before ordering to ensure correct diameter and belt match.
Please call for available options or find replacement parts.
