Continental Contitech 20042699 Cogged V-belt 3L 31 in

Product Description

The CONTINENTAL CONTITECH 20042699 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Built from high-traction rubber, this belt features a cogged construction that reduces heat buildup, increases flexibility, and improves grip on smaller-diameter sheaves. The 3L section designation identifies the belt profile, while the 31-inch outside length (30.30-inch internal length) determines the correct drive fit. It is rated for operating temperatures from -40 degrees C to 140 degrees C, making it suitable for environments with significant thermal variation.

This belt is used in residential and light commercial applications where fractional horsepower drives are common, including blower assemblies, fan drives, pump drives, and small compressor setups. HVAC technicians and mechanical service professionals typically install this belt during routine drive maintenance or as a direct replacement for a worn or cracked 3L310 belt. The cogged design makes it compatible with both standard and cogged sheaves without modification.

Key Features

• Cogged construction reduces flex resistance and heat buildup on small-diameter sheaves
• High-traction rubber compound improves grip and reduces slippage under load
• Abrasion-resistant and ozone-resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L section profile with 31-inch outside length and 30.30-inch internal length
• Fractional horsepower rating suits blower, fan, and small pump drives

Compatibility

Designed as an OEM-style replacement for 3L section fractional horsepower V-belt drives requiring a 3L310 belt. Fits standard and cogged 3L-profile sheaves used in residential and light commercial HVAC, fan, and pump drive assemblies.

Installation Notes

Belt replacement should be performed by a qualified technician with the drive system fully de-energized and locked out per applicable safety procedures. Loosen the motor mount or tensioning mechanism to remove the worn belt before seating the new belt; never roll or pry a belt onto a sheave under tension. After installation, adjust tension according to the equipment manufacturer's deflection specifications and inspect sheave grooves for wear before returning the system to service.
