Continental Contitech 20042711 Cogged V-belt 3L 43 in

Product Description

The CONTINENTAL CONTITECH 20042711 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications. Manufactured from high traction rubber, this belt carries a 3L section profile with a 43.0-inch outside length and a 42.30-inch internal length. The cogged construction reduces bending resistance, improves heat dissipation, and allows the belt to flex around smaller sheave diameters more efficiently than a standard wrapped belt. It is rated for operation from -40 degrees F to 284 degrees F (140 degrees C), making it suitable for environments with significant temperature swings. HVAC technicians, equipment mechanics, and maintenance professionals are the primary installers of this belt type.

This belt is commonly used in residential and light commercial HVAC systems, fans, blowers, and small motor-driven equipment where a 3L fractional horsepower belt is specified. The 3L section is a standard profile found across a wide range of OEM blower and fan assemblies. The belt number 3L430 is an industry-standard designation and can be cross-referenced against that number when sourcing a replacement. Applications include belt-driven air handlers, attic fans, evaporative coolers, and similar equipment requiring a compact, flexible drive belt.

Key Features

• Cogged profile reduces flex fatigue and runs cooler than standard wrapped belts
• High traction rubber compound for reliable power transfer
• Abrasion resistant and ozone resistant construction
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L section with 43.0-inch outside length and 42.30-inch internal length
• Industry belt number 3L430 for straightforward cross-reference

Compatibility

Designed as a replacement for applications specifying a 3L section fractional horsepower V-belt with a 43.0-inch outside length. Cross-references to belt number 3L430.

Installation Notes

Belt replacement on motor-driven equipment should be performed by a qualified technician. Always disconnect and lock out electrical power before removing the belt guard or accessing the drive assembly. Adjust sheave spacing to allow belt installation without forcing the belt over the pulley flanges, then set tension per the equipment manufacturer specification. Inspect sheaves for wear, misalignment, and debris before installing the new belt.
