Bando 3V710 Narrow V-belt 3V Section 71 in Od

Product Description

The BANDO 3V710 is a narrow section V-belt designed for power transmission in industrial and HVAC drive applications. Built from rubber with a black finish, this belt measures 71 inches in outside length and 3/8 inch in width, with a 0.32-inch thickness. The 3V section profile follows RMA standards, making it a direct match for sheaves and drives engineered to that specification. It carries heat-resistant and oil-resistant properties, which extend service life in mechanical rooms, rooftop units, and equipment rooms where belt operating conditions are demanding. Licensed HVAC technicians and industrial mechanics are the typical installers.

The 3V710 suits residential and light commercial HVAC systems as well as general industrial power transmission drives where a narrow 3V section belt is specified. Common applications include blower and fan drives on air handling units, package units, and belt-driven compressors. Any drive system calling out a 3V section belt with a 71-inch outside circumference is a candidate for this replacement. Its narrow profile allows use in compact multi-groove drive arrangements where wider classical belts do not fit.

Key Features

• Narrow 3V section profile meets RMA dimensional standards for direct sheave compatibility
• 71-inch outside length suits a wide range of blower and fan drive center distances
• Heat-resistant rubber construction handles elevated temperatures in HVAC and mechanical room environments
• Oil-resistant compound reduces degradation from incidental lubricant exposure
• 3/8-inch belt width with 0.32-inch thickness fits standard 3V grooved sheaves
• Weighs 0.325 pounds for easy single-technician handling during belt replacement

Compatibility

Designed as an OEM-style replacement for any drive system specifying a narrow 3V section V-belt with a 71-inch outside length and 3/8-inch width, conforming to RMA standards.

Installation Notes

Belt replacement is performed by qualified HVAC technicians or industrial mechanics. Always disconnect and lock out power to the drive unit before removing the belt guard or accessing the sheaves. Adjust drive center distance to allow belt installation without forcing the belt over sheave flanges, then re-tension according to the equipment manufacturer's deflection specification. Inspect sheave grooves for wear or misalignment before installing a new belt, as worn grooves accelerate belt failure.
