Trane SHE05324 Sheave Single Groove 0.75 Bore V-belt

Product Description

The TRANE SHE05324 is a single-groove V-belt sheave designed for use in HVAC blower and fan drive assemblies. The AK44x3/4 designation identifies this as an A-series fixed-bore pulley with a 0.75 inch bore diameter, engineered to accept standard A-section or 4L V-belts. Sheaves of this type transfer rotational power from a motor shaft to a blower wheel or fan shaft, controlling airflow by setting the effective drive ratio. This component is installed by licensed HVAC technicians during routine belt-drive maintenance, blower motor replacement, or system commissioning.

This sheave is suited for residential and light commercial HVAC air handling units and furnace blower sections where a fixed-pitch, single-groove V-belt drive is specified. The 0.75 inch bore is a common motor-shaft size in fractional and small integral horsepower blower motor applications. It is typically found in forced-air systems requiring precise belt alignment and consistent belt tension to maintain rated airflow and system efficiency.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all electrical power to the unit before removing or installing any drive components. Ensure the sheave bore seats fully on the shaft and that the set screw is tightened securely before restoring power.
