Continental Contitech 20042003 V-belt Section a A78 80.2 in

Product Description

The CONTINENTAL CONTITECH 20042003 is a Section A V-belt designed for industrial and HVAC drive applications requiring a reliable, long-service power transmission belt. Constructed from Wingprene rubber-impregnated fabric, this belt delivers strong resistance to heat and oil, making it suitable for demanding mechanical environments. It carries an outside length of 80.2 inches and an internal length of 79.30 inches, conforming to the A78 belt designation. The HY-T Matchmaker style ensures consistent cross-section geometry for matched-set and single-belt drive systems. Installation is handled by mechanical contractors, HVAC technicians, and industrial maintenance professionals.

This V-belt is suited for use in belt-driven blower assemblies, fan drives, pump drives, and general industrial power transmission systems. The Section A profile is one of the most common cross-sections found in residential and light commercial HVAC equipment, as well as agricultural and industrial machinery. The A78 designation allows direct cross-reference when replacing worn or broken drive belts during scheduled maintenance or emergency service calls. The belt meets DIN 2215 and DIN 7753 dimensional and performance standards.

Installation Notes

V-belt replacement is typically performed by HVAC technicians, millwrights, or qualified maintenance personnel. Always de-energize and lock out the equipment before removing the belt guard or accessing the drive sheaves. Check sheave alignment and groove condition before installing the new belt, and adjust center distance to achieve proper belt tension without over-tensioning. Do not pry the belt onto sheaves using tools that could damage the belt cords.
