Value Collection 20472482 V-belt 3L 42 in Fractional Hp

Product Description

The VALUE COLLECTION 20472482 is a 3L-section fractional horsepower V-belt designed for light-duty power transmission applications in HVAC, appliance, and small motor drive systems. Manufactured from rubber, this belt measures 42 inches in outside length and carries the belt number 3L420. The 3L cross-section is a standard fractional horsepower profile used widely in smaller drives where a full classical-section belt would be oversized. Weighing just 0.14 pounds, it is a direct drop-in replacement suited for quick field or shop repairs without special tooling.

This belt fits applications where 3L fractional horsepower V-belt drives are specified, including small HVAC blower assemblies, evaporative cooler drives, shop equipment, and light-duty appliance motors. It is appropriate for both residential and light commercial installations. Technicians servicing equipment that calls out a 3L420 belt designation can use this part as an OEM-equivalent replacement without modification to existing sheave or pulley setups.

Key Features

• 3L belt section profile — standard fractional horsepower V-belt geometry
• 42-inch outside length (3L420 designation)
• Rubber construction for durability and flexibility across typical operating temperature ranges
• Lightweight at 0.14 pounds — easy to carry as a service spare
• Single-unit packaging — no minimum bundle requirement

Compatibility

Designed as an OEM-style replacement for equipment specifying a 3L420 fractional horsepower V-belt. Verify outside length, cross-section, and drive configuration against the equipment nameplate or service manual before installation.

Installation Notes

V-belt replacement is typically performed by HVAC technicians, appliance service technicians, or maintenance mechanics. Always de-energize and lock out the equipment before removing the belt guard or accessing the drive. Loosen the motor mount or tensioner to relieve belt tension before removal — never pry a belt off a sheave under load, as this can damage the pulley groove and reduce belt life. After installation, adjust tension per the equipment manufacturer specification and confirm proper belt tracking before returning the unit to service.
