Continental Contitech 20042049 V-belt Section B 34in B31

Product Description

The CONTINENTAL CONTITECH 20042049 is a Section B V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built from Wingprene rubber-impregnated fabric, this belt delivers resistance to heat, oil, and environmental exposure. It carries a 34-inch outside length (32.80-inch internal length) and is designated Belt Number B31 under the HY-T Matchmaker product line. The belt handles a working temperature range of -40 degrees C to 140 degrees C, making it suitable for both cold-start conditions and sustained high-temperature drive environments. HVAC technicians, millwrights, and mechanical service professionals install this type of belt during routine drive maintenance or blower motor service.

This V-belt fits standard Section B drive configurations found on belt-driven HVAC air handlers, fan coil units, commercial rooftop units, and general industrial machinery. The B31 designation corresponds to the classical B-section belt sizing standard, allowing direct interchangeability with any drive system calling out a B31 belt. It is sold individually and is appropriate for both OEM replacement and aftermarket drive service.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical service professionals. Always disconnect and lock out power to the drive unit before removing the old belt or installing the new one. Adjust sheave spacing to allow belt seating without forcing, then set proper tension per the equipment manufacturer's deflection specification before returning the drive to service. Do not pry the belt over a sheave with sharp tools, as this can damage the belt cords.
