Continental Contitech 20042685 Cogged V-belt 3L 17 in

Product Description

The CONTINENTAL CONTITECH 20042685 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Belt number 3L170, it features a 3L cross-section with a 17.0-inch outside length and a 16.30-inch internal length. Constructed from high traction rubber, the cogged design reduces bending resistance and heat buildup, improving efficiency and belt life on smaller-diameter pulleys. The belt is rated for service from -40 degrees C to 140 degrees C and carries abrasion and ozone resistance, making it suitable for both indoor and outdoor installations.

This belt is used in fractional horsepower drive applications commonly found in residential and light commercial HVAC equipment, blower assemblies, small compressors, fans, and agricultural or shop equipment. The 3L section is a standard fractional horsepower profile widely used on OEM drives where space is limited and compact belt geometry is required. Technicians replacing worn or cracked drive belts on blower motors and fan assemblies will find this a direct cross to the 3L170 designation used across multiple equipment platforms.

Key Features

• Cogged construction reduces bending resistance and improves heat dissipation on small-diameter sheaves
• High traction rubber compound for positive grip and reduced slip under load
• Abrasion resistant and ozone resistant for extended service life in outdoor or harsh environments
• Wide operating temperature range: -40 degrees C to 140 degrees C
• Standard 3L170 belt designation for straightforward cross-referencing
• Fractional horsepower profile suited to compact OEM drive configurations

Compatibility

Designed as an OEM-style replacement for fractional horsepower V-belt drives using the standard 3L170 belt designation across HVAC, fan, blower, and light mechanical equipment applications.

Installation Notes

Belt replacement should be performed by a qualified technician after de-energizing the equipment and locking out the power source per OSHA lockout/tagout procedures. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Do not pry or force the belt onto the sheave; relieve tension by adjusting the motor mount before seating the belt, then re-tension according to the equipment manufacturer's specification. Check alignment with a straightedge after installation to minimize side loading and premature wear.
