Dial 6341 Blower Pulley 14 X 1 Inch Evaporative Cooler

Product Description

The DIAL 6341 is a single-groove blower pulley designed for residential evaporative coolers. Measuring 14 inches in diameter with a 1-inch bore, it transfers power from the motor to the blower assembly, maintaining consistent airflow through the cooling system. The keyway design locks the pulley onto the shaft, preventing slippage under load. Cast from zinc, the pulley delivers corrosion resistance suitable for the wet operating environment of evaporative cooler installations. This part is typically installed by HVAC technicians or experienced service personnel performing seasonal maintenance or component replacement on swamp cooler units.

The DIAL 6341 is suited for residential evaporative cooler applications where the original blower pulley has worn, cracked, or lost its keyway engagement. It fits systems that use a 14-inch single-groove pulley with a 1-inch bore and standard keyway slot. Typical install scenarios include seasonal startup service, belt-drive system rebuilds, and motor or blower shaft replacements where the existing pulley must be swapped to match the new component. No compatibility with specific brand model numbers is stated in available product data.

Installation Notes

Installation should be performed by a qualified HVAC technician or experienced service professional. Disconnect power to the evaporative cooler unit at the breaker before removing the existing pulley or handling belt-drive components. Ensure the keyway on the shaft is clean and undamaged before seating the new pulley, and verify belt tension and alignment after installation before returning the unit to service.
