Continental Contitech 20042746 Cogged V-belt 4L 20 in

Product Description

The CONTINENTAL CONTITECH 20042746 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications across HVAC, refrigeration, and general mechanical equipment. Manufactured from high-traction rubber, this 4L-section belt measures 20 inches outside length with a 19-inch internal length. The cogged construction reduces flex stress on the belt, lowers heat buildup during operation, and improves efficiency over standard wrapped belts. Rated for a maximum working temperature of 140 degrees C and a minimum of -40 degrees C, this belt handles demanding thermal environments without cracking or glazing. HVAC technicians and equipment service pros are the primary installers.

This belt fits single-groove and multi-groove sheave arrangements common in residential and light commercial HVAC systems, including blower assemblies, condenser fan drives, and small compressor drive applications. The 4L section is a standard fractional horsepower profile widely used in equipment with smaller-diameter sheaves. The belt number 4L200 is the industry-standard designation for this size, making cross-referencing to OEM requirements straightforward. It is sold individually and is suitable for both replacement and new-installation scenarios on belt-drive equipment.

Key Features

• Cogged design reduces heat buildup and improves flex life over wrapped V-belts
• High-traction rubber compound resists abrasion and ozone degradation
• 4L section profile fits standard fractional horsepower sheaves
• 20-inch outside length, 19-inch internal length for precise drive sizing
• Operating range from -40 degrees C to 140 degrees C
• Industry belt number 4L200 for easy OEM cross-reference

Compatibility

Designed as an OEM-style replacement for fractional horsepower belt-drive applications using 4L-section sheaves, including residential and light commercial HVAC blower and fan drive assemblies.

Installation Notes

Belt replacement is typically performed by a licensed HVAC technician or qualified equipment service professional. Disconnect and lock out all power to the unit before removing the old belt or adjusting sheave positions. Proper tensioning is critical — an overtightened belt accelerates bearing wear while an undertightened belt slips and glazes; follow equipment manufacturer tension specifications. Inspect sheave grooves for wear or misalignment before installing the new belt.
