Dial 6324 Blower Pulley 10 Inch Keyway Evaporative Cooler

Product Description

The DIAL 6324 is a single-groove blower pulley designed for residential evaporative coolers. Measuring 10 inches in diameter with a 1-inch bore, this zinc pulley features a keyway slot that locks the pulley securely onto the shaft, preventing slippage during operation. The round profile and precision bore support smooth, consistent power transfer from the motor to the blower assembly. HVAC technicians and evaporative cooler service pros install this part as a direct replacement for worn or damaged pulleys on swamp cooler blower shafts.

This pulley is suited for residential evaporative cooling systems where the blower assembly is belt-driven. It fits applications requiring a 10-inch diameter single-groove pulley with a 1-inch keyed bore. The keyway design is standard for direct-drive and belt-drive blower configurations found in rooftop and side-draft evaporative coolers common in dry-climate residential installs.

• 10-inch diameter with 1-inch keyed bore for secure shaft engagement
• Single-groove design supports standard V-belt blower drive configurations
• Zinc construction resists corrosion in outdoor and rooftop cooler environments

Compatibility

Designed as an OEM-style replacement pulley for residential evaporative cooler blower assemblies requiring a 10-inch single-groove pulley with a 1-inch keyed bore.

Installation Notes

Installation should be performed by a qualified HVAC technician or evaporative cooler service professional. Disconnect power to the unit at the breaker before beginning any work on the blower assembly. Ensure the keyway and set screw are fully seated and secured before restoring power. Inspect the drive belt for wear and replace if needed before returning the system to service.
