Continental Contitech 20042073 V-belt Section B 58 in B55

Product Description

The CONTINENTAL CONTITECH 20042073 is a Section B V-belt engineered for reliable power transmission in mechanical drive applications common to HVAC, industrial, and commercial equipment. Built with Wingprene rubber-impregnated fabric construction, this belt delivers resistance to heat, oil, and environmental degradation. It carries a B55 belt designation with a 58-inch outside length and a 56.80-inch internal length. The belt is rated for operating temperatures from -40 degrees C to 140 degrees C, making it suitable for demanding seasonal and year-round service conditions. HVAC technicians, mechanical contractors, and maintenance professionals typically install this belt on blower and fan drive assemblies.

This V-belt is used in residential and light commercial HVAC systems, as well as industrial equipment where a Section B drive belt is specified. Typical applications include air handler blower drives, condenser fan drives, and general-purpose machinery where a B55 belt is called out by the equipment manufacturer. The HY-T Matchmaker designation indicates this belt is designed to run in matched sets on multi-groove sheave drives, ensuring balanced load distribution across all belt positions.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified mechanical maintenance personnel. Disconnect and lock out all power to the unit before removing the old belt or installing the new one. Use a sheave gauge to verify groove profile compatibility and inspect sheaves for wear before installing a new belt. Avoid prying or rolling belts onto sheaves with tools that can damage the cord structure — always release tension via the motor adjustment before seating the belt.
