Continental Contitech 20042708 Cogged V-belt 3L 40 in

Product Description

The CONTINENTAL CONTITECH 20042708 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications. Manufactured from high traction rubber, this 3L-section belt measures 40 inches in outside length with an internal length of 39.30 inches. The cogged design reduces bending resistance and heat buildup, making it suitable for smaller-diameter sheaves common in HVAC blower assemblies, fans, and light commercial equipment. Licensed HVAC technicians and mechanical service pros install this belt type as a direct replacement during routine drive maintenance.

This belt is used in residential and light commercial systems where a 3L-section fractional horsepower drive is specified. Typical applications include indoor blower assemblies, condenser fan drives, and other small-sheave power transmission setups requiring a 40-inch outside length belt. The cogged construction allows flexing over smaller pulleys without the cracking and heat fatigue associated with standard wrapped belts in the same horsepower class.

Key Features

• Cogged design reduces heat buildup and flex fatigue on small-diameter sheaves
• High traction rubber compound for reliable grip and power transfer
• Abrasion resistant construction extends service life in dusty or debris-present environments
• Ozone resistant material resists degradation in outdoor and mixed-air equipment exposures
• Wide operating temperature range from -40 degrees F to 284 degrees F (140 degrees C)
• 3L-section profile matches standard fractional horsepower sheave grooves

Compatibility

Designed as an OEM-style replacement for fractional horsepower drives requiring a 3L-section cogged V-belt with a 40-inch outside length. Cross-references to belt number 3L400.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service professionals. Always de-energize and lock out the unit before removing belt guards or drive covers. Do not pry belts over sheave flanges with hard tools, as this can damage the belt cords and reduce service life. Check sheave alignment and condition before installing the new belt, and verify proper tension per the equipment manufacturer's drive specification.
