Continental Contitech 20042744 Cogged V-belt 4L 18 in

Product Description

The CONTINENTAL CONTITECH 20042744 is a fractional horsepower cogged V-belt in the 4L section, also identified by belt number 4L180. Built from high traction rubber, this belt delivers reliable power transmission in light-duty drive applications. The cogged profile reduces bending resistance, which improves flexibility on small-diameter sheaves and generates less heat during operation. It carries an outside length of 18 inches and an internal length of 17 inches. Rated for a maximum working temperature of 140 degrees C and a minimum of -40 degrees C, it performs across a wide thermal range. Abrasion resistance and ozone resistance extend service life in demanding environments.

This belt is suited for residential and light commercial equipment where fractional horsepower V-belt drives are standard. Common applications include HVAC blower assemblies, small air handlers, exhaust fans, and other belt-driven equipment that use 4L-section sheaves. It is a direct form-fit replacement for worn or cracked 4L180 belts found in these systems. HVAC technicians and maintenance mechanics are the primary installers, though the swap is also within reach of knowledgeable DIYers working on compatible equipment.

Key Features

• Cogged design reduces bending resistance and heat buildup on small-diameter sheaves
• High traction rubber construction for positive grip and reduced slippage
• Abrasion resistant and ozone resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 4L section profile with 18-inch outside length and 17-inch internal length

Compatibility

Designed as a direct replacement for 4L180 fractional horsepower V-belt applications using standard 4L-section sheaves and pulleys in HVAC, fan, and light-duty drive systems.

Installation Notes

De-energize and lock out the equipment before removing the old belt. Loosen the motor mount or tensioner to allow belt removal and installation without prying, which can damage the belt or sheave grooves. After seating the new belt, adjust tension according to the equipment manufacturer's deflection specification before restoring power. Inspect sheave grooves for wear or debris that could accelerate belt wear.
