Description

The CONTINENTAL CONTITECH 20042696 is a fractional horsepower cogged V-belt engineered for light-duty power transmission applications. Carrying the belt number 3L280, it features a 3L cross-section profile with a 28-inch outside length and a 27.30-inch internal length. The cogged construction reduces bending resistance and heat buildup, making it well-suited for smaller sheave diameters. Built from high traction rubber, this belt delivers consistent grip and is rated for operating temperatures from -40 degrees C up to 140 degrees C. HVAC technicians, equipment mechanics, and service pros use this style of belt across a wide range of motor-driven applications.

The 3L280 cogged V-belt is used in residential and light commercial HVAC systems, fans, blowers, compressors, and other fractional horsepower equipment where a 3L-section belt is specified. It is a direct replacement for any OEM or aftermarket application calling for a 3L280 belt. The cogged profile improves flexibility and heat dissipation, which extends service life in high-cycle applications such as air handlers and belt-driven blower assemblies.

Installation Notes

Installation is typically performed by HVAC technicians or equipment mechanics. Always disconnect and lock out power to the unit before removing or installing a drive belt. Inspect sheaves and pulleys for wear, misalignment, or debris before fitting the new belt, and verify the replacement belt number matches the OEM specification. Do not pry the belt over sheave flanges with sharp tools, as this can damage the cog structure and reduce service life.
