4L360 Classical V-belt 36 Inches

Product Description

The 4L360 is a classical V-belt used to transfer rotational power between pulleys in belt-driven mechanical systems. It follows the standard 4L fractional horsepower cross-section profile, which measures approximately 0.5 inches wide at the top. The 36-inch outside circumference makes it suitable for moderate-span drive systems found in residential and light commercial equipment. Constructed from rubber, this belt is designed to handle the flex stress of continuous operation. HVAC technicians, equipment mechanics, and facilities maintenance professionals are the typical installers for this belt type.

Classical V-belts in the 4L series are widely used in belt-driven blower assemblies, fan systems, and light-duty power transmission applications. The 4L360 fits drive configurations where a 36-inch outside circumference belt is specified. Common applications include furnace air handlers, evaporative coolers, ventilation fans, and similar equipment that uses fractional horsepower sheave-and-belt drives. Always verify the driven equipment manufacturer's belt specification before installation.

Key Features

• Standard 4L fractional horsepower V-belt cross-section for wide sheave compatibility
• 36-inch outside circumference for moderate-span pulley drives
• Rubber construction provides flexibility and resistance to flex fatigue
• Suitable for residential and light commercial belt-driven blower and fan systems
• Lightweight at 1.33 pounds for easy single-technician handling

Compatibility

Designed as an OEM-style replacement for belt-driven blower and fan assemblies that specify a 4L-series classical V-belt with a 36-inch outside circumference.

Installation Notes

A licensed HVAC technician or qualified mechanical trades professional should perform belt replacement. Always disconnect and lock out power to the equipment before removing belt guards or accessing the drive assembly. Adjust tensioner or motor mount to relieve tension before removing the old belt, then seat the new belt fully in the sheave grooves before restoring tension. Do not use tools to force the belt over pulley flanges, as this can damage the belt cord structure.
