Lennox 31K68 Blower Pulley 5.75" OD 1" Bore

The Lennox 31K68 Blower Pulley is quite an essential component in effective airflow in your HVAC system. It is a single strand groove pulley made of cast iron for strength and to last long. This 1" bore pulley is intended for use on a blower motor shaft that has a 1" diameter as well. While working the motor in the unit, the pulley uses the belt to rotate the blower wheel, which forces air to circulate inside the duct system of your heating or cooling system. It is crucial to replace a worn or damaged blower pulley to impact the proper airflow within your system properly.
