Continental Contitech 20042743 Cogged V-belt 4L 17 in

Product Description

The CONTINENTAL CONTITECH 20042743 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Manufactured from high traction rubber, this belt carries the industry designation 4L170, indicating a 4L cross-section with a 17-inch outside length and a 16-inch internal length. The cogged construction reduces heat buildup and flexing resistance, making it a practical choice for smaller sheave diameters common in fan and blower drive assemblies. Licensed HVAC technicians and mechanical service pros install this belt type during routine maintenance or component replacement.

This belt is suited for residential and light commercial HVAC systems, as well as general-purpose equipment using fractional horsepower drives. Typical applications include condenser fan motors, evaporator blower assemblies, and small compressor drive arrangements where a 4L-section belt is specified. The 4L170 designation is a standard fractional horsepower size recognized across a wide range of OEM and aftermarket drive systems, allowing straightforward cross-referencing during service calls.

• Rated for operating temperatures from -40 degrees C to 140 degrees C
• Standard 4L170 designation for easy cross-referencing and replacement
• Fractional horsepower V-belt profile fits drives requiring a 4L-section belt

Compatibility

Designed as an OEM-style replacement for fractional horsepower drive systems specifying a 4L-section V-belt with a 17-inch outside length and 16-inch internal length.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical service professional. Always disconnect and lock out power to the unit before removing or installing drive belts. Never pry a belt over sheave flanges with sharp tools, as this can damage the belt cords and reduce service life. After installation, verify belt tension and alignment per the equipment manufacturer's specifications before returning the unit to service.
