Rcd p461-3505 Hvac Pulley 4 in X 5/8 in Bore

Product Description

The RCD p461-3505 is a replacement belt-drive pulley designed for use in HVAC air handling and blower applications. With a 4-inch outer diameter and a 5/8-inch bore, this pulley is sized for standard belt-drive blower assemblies found in residential and light commercial HVAC equipment. It measures 3.5 inches in length, 3.5 inches in width, and 0.5 inches in height, making it a compact component suited for tight mechanical spaces. Licensed HVAC technicians install this part when servicing blower motor drives that show wear, cracking, or misalignment on the existing pulley.

This pulley is applicable to belt-drive blower systems in residential and light commercial HVAC units. It is a direct OEM-style replacement part, suited for installations where the original pulley has worn grooves, a damaged bore, or has caused belt slippage. Technicians working on furnace air handlers, fan coil units, or standalone blower assemblies will encounter this pulley size frequently in standard residential configurations.
