Continental Contitech 20042725 Cogged V-belt 3L 56in

Product Description

The CONTINENTAL CONTITECH 20042725 is a fractional horsepower cogged V-belt engineered for light-duty power transmission applications. Constructed from high traction rubber, this belt features a cogged (notched) profile that reduces bending resistance, runs cooler, and improves flexibility around smaller-diameter sheaves. It carries a 3L section designation with a 56-inch outside length and a 55.30-inch internal length. HVAC technicians, equipment mechanics, and maintenance professionals install this belt on fractional horsepower drives in blower assemblies, fans, and similar belt-driven equipment. The cogged construction also contributes to higher power transmission efficiency compared to a standard wrapped belt of the same section.

This belt is suited for residential and light commercial HVAC systems, small appliances, shop equipment, and other fractional horsepower belt-driven machinery where a 3L section is specified. It is rated for operation across a wide temperature range, from -40 degrees C to 140 degrees C, making it appropriate for both indoor and outdoor equipment installations. Its abrasion-resistant and ozone-resistant compound extends service life in environments where rubber degradation is a concern, including rooftop and outdoor-mounted equipment.

Key Features

• Cogged (notched) profile reduces heat buildup and improves flex on small-diameter sheaves
• High traction rubber compound for reliable grip and power transfer
• Abrasion resistant and ozone resistant for extended outdoor and rooftop service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L section fractional horsepower sizing for common light-duty blower and fan drives
• Belt number 3L560 for cross-reference identification

Compatibility

Designed as an OEM-style replacement fractional horsepower V-belt for equipment specifying a 3L section belt with a 56-inch outside length. Cross-reference belt number 3L560 when sourcing replacements.

Installation Notes

Belt replacement is typically performed by HVAC technicians or equipment mechanics. Always de-energize and lock out the equipment before removing the belt guard or accessing the drive. Never pry or force a belt over sheave flanges; relieve tension by adjusting the motor mount before installation. After seating the new belt, adjust drive tension per the equipment manufacturer specification and confirm sheave alignment before restoring power.
