Continental Contitech 20042002 Section a V-belt A77 79.2in

Product Description

The CONTINENTAL CONTITECH 20042002 is a Section A classical V-belt designed for power transmission in industrial, commercial, and HVAC drive systems. Built from Wingprene rubber-impregnated fabric, this belt delivers reliable performance across a wide temperature range, from -40 degrees C to 140 degrees C, making it suitable for demanding environments where heat and oil exposure are common. With an outside length of 79.2 inches and an internal length of 78.30 inches, it carries the standard belt designation A77. Licensed HVAC technicians, millwrights, and mechanical contractors install this belt on belt-drive blowers, fans, and pump assemblies.

This V-belt is used in belt-drive applications across residential and light commercial HVAC systems, industrial fans, pump drives, and general power transmission equipment. The HY-T Matchmaker profile matches standard A-section sheaves and pulleys, making it a direct fit for systems originally spec'd for an A77 belt. It conforms to DIN 2215 and DIN 7753 standards, ensuring dimensional accuracy and consistent performance in matched or single-belt drive configurations.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Always de-energize and lock out the equipment before removing or installing the belt. Never pry or force the belt over sheave flanges; adjust the drive to reduce center distance before seating the belt, then re-tension to manufacturer drive specifications. Inspect sheaves and pulleys for wear or misalignment before installing a new belt.
