Continental Contitech 20042713 Cogged V-belt 3L 45in

Product Description

The CONTINENTAL CONTITECH 20042713 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 bending resistance and heat buildup, improving efficiency and belt life on smaller-diameter sheaves. It carries the belt number 3L450, indicating a 3L cross-section with a 45-inch outside length. The cogged profile also provides better grip on variable-speed drives common in blower and fan assemblies. Licensed HVAC technicians and mechanical service pros install this type of belt during routine maintenance or component replacement on belt-driven air handlers and fan coil units.

This belt is suited for residential and light commercial HVAC systems, refrigeration equipment, and other fractional horsepower machinery that uses a 3L-section drive. The 3L cross-section is a standard fractional horsepower profile commonly found on evaporator fan drives, condenser blower assemblies, and small compressor drive systems. Its abrasion-resistant and ozone-resistant compound makes it appropriate for both indoor mechanical rooms and outdoor equipment exposed to environmental wear. The 44.30-inch internal length ensures correct fit on standard 3L450-spec sheave configurations.

Key Features

• Cogged construction reduces bending resistance and heat buildup on small-diameter sheaves
• High traction rubber compound for reliable grip and power transfer
• Abrasion resistant and ozone resistant for extended service life in harsh environments
• Rated for operation from -40 degrees C to 140 degrees C
• 3L section fractional horsepower profile with 45-inch outside length and 44.30-inch internal length
• Belt number 3L450 for direct cross-reference and replacement sourcing

Compatibility

Designed as a direct replacement for any application calling for a 3L450 fractional horsepower V-belt. Fits standard 3L-section sheaves and pulleys used in belt-driven HVAC blowers, fan coil units, refrigeration evaporator fans, and general light-duty mechanical drives.

Installation Notes

Disconnect and lock out all power to the unit before removing the old belt or installing a new one. Adjust sheave center distance to relieve tension prior to removal and set correct tension after installation per the equipment manufacturer's drive specifications. Inspect sheave grooves for wear or misalignment before installing a new belt, as worn grooves accelerate belt wear. Belt installation is typically performed by licensed HVAC technicians or qualified mechanical service personnel.
