Product Description

The VALUE COLLECTION 20565057 is a Section B classic V-belt designed for general-purpose power transmission applications. Constructed from rubber, this belt delivers reliable torque transfer across pulleys in a wide range of industrial and mechanical drive systems. The outside length measures 135.9 inches, with an internal length of 134.80 inches, and it carries the standard belt designation B133. Licensed HVAC technicians, mechanical contractors, and maintenance professionals regularly install and replace belts of this type on fan and blower drive assemblies.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical maintenance professionals. Disconnect and lock out all electrical power to the drive system before beginning work. Relieve drive tension by adjusting the motor mount or idler before removing the old belt, and confirm sheave alignment before tensioning the new belt. Refer to equipment manufacturer guidelines and applicable mechanical codes for proper tensioning procedures.
