Continental Contitech 20042731 Cogged V-belt 3L 62 in

Product Description

The CONTINENTAL CONTITECH 20042731 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications. Belt number 3L620, it features a 3L cross-section with a 62-inch outside length and a 61.30-inch internal length. Constructed from high traction rubber, this belt delivers reliable grip and flexibility in demanding drive systems. The cogged design reduces bending resistance, improving efficiency and extending belt life in smaller sheave applications. It is rated for a maximum working temperature of 140 degrees C and a minimum working temperature of -40 degrees C, making it suitable for both indoor and outdoor mechanical systems.

This belt is intended for fractional horsepower drive applications found in residential and light commercial equipment including HVAC air handlers, blowers, fans, and small machinery. The 3L section is a standard fractional horsepower profile used widely in appliance motors, portable equipment, and auxiliary drive systems. Licensed HVAC technicians and mechanical service professionals routinely replace this belt during scheduled maintenance or when a worn belt causes slippage, noise, or reduced airflow.

Key Features

• Abrasion resistant and ozone resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L section profile with 62-inch outside length and 61.30-inch internal length
• Fractional horsepower rating suits small motor and blower drive applications

Compatibility

Designed as an OEM-style replacement for fractional horsepower drive systems using a 3L-section cogged V-belt with a 62-inch outside length. Cross-references to belt number 3L620.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. Always disconnect and lock out power to the unit before removing the belt guard or accessing the drive sheaves. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Never pry or force the belt over a sheave with excessive tension; adjust the motor mount or idler to achieve proper belt tension per the equipment manufacturer guidelines.
