Lau G078052435 V-belt Pulley 4.75in Od 7/8in Bore

Product Description

The LAU G078052435 is a single-groove V-belt pulley designed for use in belt-driven HVAC blower and fan assemblies. With an outer diameter of 4.75 inches and a bore size of 7/8 inches, this pulley mounts directly to a motor or blower shaft to transfer rotational power via a standard V-belt drive system. The one-groove configuration suits single-belt setups common in residential and light commercial air handling equipment. HVAC technicians and mechanical contractors install this component during motor replacements, drive system retrofits, or preventive maintenance rebuilds.

This pulley is suited for belt-driven blower systems found in furnaces, air handlers, and rooftop units where a single V-belt drive connects the motor to the blower wheel. It is appropriate for installations requiring a 4.75-inch OD pulley with a 7/8-inch shaft bore. The one-groove design limits this part to single-belt drive configurations. It is sold individually with a box quantity of one.

Key Features

• 4.75-inch outer diameter for standard single-belt drive sizing
• 7/8-inch bore fits common motor and blower shaft diameters
• One-groove design for single V-belt drive systems

Compatibility

Designed as an OEM-style replacement pulley for belt-driven HVAC blower and fan systems requiring a 4.75-inch OD, 7/8-inch bore, single-groove V-belt pulley configuration.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out electrical power to the unit before removing or installing any drive components. Ensure the bore fits the shaft without forcing, and verify belt alignment and tension after installation to prevent premature wear. Consult the equipment manufacturer's service documentation for drive system specifications.
