Continental Contitech 20042726 Cogged V-belt 3L 57in

Product Description

The CONTINENTAL CONTITECH 20042726 is a cogged fractional horsepower V-belt in the 3L section, with a 57.0 inch outside length and a 56.30 inch internal length. Manufactured from high traction rubber, this belt is engineered for reliable power transmission in light-duty drive applications. The cogged construction reduces bending resistance, allowing the belt to run cooler and flex smoothly around smaller sheaves. It carries a working temperature range of -40 degrees C to 140 degrees C, making it suitable for environments with wide thermal swings. Licensed HVAC technicians, equipment service pros, and industrial maintenance personnel commonly install this belt type.

The 3L-section cogged V-belt is commonly found in residential and light commercial HVAC systems, small compressors, fans, blowers, and general fractional horsepower drive assemblies. The 3L570 designation identifies the belt by section and outside length, which is the standard specification method for sourcing a direct replacement. This belt is sold individually and is appropriate for single or paired drive configurations where a 3L section belt is specified.

Installation Notes

Installation is performed by HVAC technicians, equipment service professionals, or qualified maintenance personnel. Disconnect and lock out all power to the drive system before removing the old belt or installing the new one. Adjust sheave spacing to allow the belt to seat without prying, then set tension to the drive manufacturer's specification using a belt tension gauge. Inspect sheave grooves for wear or misalignment before installing the replacement belt.
