Continental Contitech 20042756 Cogged V-belt 4L 30 in

Product Description

The CONTINENTAL CONTITECH 20042756 is a cogged fractional horsepower V-belt in the 4L section, also known by belt number 4L300. Built from high traction rubber, this belt delivers reliable power transmission in light-duty and fractional horsepower drive applications. The cogged profile reduces bending resistance and heat buildup, extending service life on smaller-diameter sheaves. With a 30-inch outside length and 29-inch internal length, the belt is sized for common HVAC blower drives, fan assemblies, and other fractional HP equipment found in residential and light commercial settings. It is rated for operating temperatures from -40 degrees F to 284 degrees F (140 degrees C).

This belt is suited for fractional horsepower drive systems including HVAC blower assemblies, air handlers, evaporative coolers, and small fan drives in residential and light commercial installations. The 4L section profile is a standard fractional HP designation widely used across equipment from multiple manufacturers. HVAC technicians, equipment service technicians, and maintenance professionals routinely replace this belt during preventive maintenance or following belt failure diagnostics. Its abrasion-resistant and ozone-resistant construction makes it appropriate for both indoor mechanical rooms and outdoor-exposed equipment enclosures.

Key Features

• Cogged design reduces flex resistance and heat buildup on small-diameter sheaves
• High traction rubber construction for dependable grip and power transfer
• Abrasion resistant and ozone resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 4L section fractional horsepower profile fits standard 4L-groove sheaves
• 30-inch outside length, 29-inch internal length for precise drive sizing

Compatibility

Designed as an OEM-style replacement fractional horsepower V-belt for drives using the 4L section profile and a 30-inch outside length designation (belt number 4L300).

Installation Notes

Disconnect and lock out power to the equipment before removing or installing any drive belt. Release drive tension by adjusting the motor mount or idler before seating the belt — never force a belt over sheave flanges under tension, as this can damage belt cords. After installation, set belt deflection per the equipment manufacturer's specification and check alignment of sheaves before returning the unit to service. HVAC technicians typically perform this work as part of scheduled preventive maintenance or blower section service.
