Value Collection 20526842 V-belt Section a 33.1 in A31

Product Description

The VALUE COLLECTION 20526842 is a Section A classic V-belt designed for general-purpose power transmission in HVAC, refrigeration, and mechanical equipment applications. Built from rubber construction, this belt measures 33.1 inches in outside length and 32.30 inches in internal length, conforming to the A31 belt designation. The classic V-belt profile seats firmly into standard A-section sheaves and pulleys, delivering reliable torque transfer in belt-driven fan, blower, and compressor assemblies. HVAC technicians, refrigeration mechanics, and maintenance professionals install this style of belt routinely as a scheduled replacement or emergency service component.

Section A V-belts are a standard drive component in residential and light commercial HVAC equipment, including belt-drive air handlers, furnace blowers, condenser fan assemblies, and rooftop units. The A31 designation identifies the belt number within the A-section family, making cross-referencing straightforward against OEM belt call-outs on equipment nameplates. This belt is also found in general industrial machinery, pump drives, and agricultural equipment where A-section drive geometry is specified.

Key Features

• A-section classic V-belt profile for standard A-section sheaves and pulleys
• 33.1 inches outside length with 32.30 inches internal length for precise fitment
• Rubber construction for flexibility, durability, and heat resistance in mechanical drive service
• A31 belt number simplifies OEM cross-reference from equipment nameplates
• Classic style seats consistently into fixed and adjustable sheave configurations

Compatibility

Designed as an OEM-style replacement for belt-driven HVAC blower assemblies, fan drives, and light mechanical equipment specifying an A-section belt with 33.1 inches outside length or the A31 belt designation.

Installation Notes

Belt replacement is typically performed by HVAC technicians or maintenance mechanics. Always disconnect and lock out power to the equipment before removing drive guards or handling belts. Loosen the motor mount or tensioning bracket to relieve belt tension before removal, and verify proper tension per the equipment manufacturer's deflection specification after installation. Never pry a belt onto a sheave with a tool, as this can damage belt cords and shorten service life.
