Installation, Tensioning & Maintenance of V-BeltsImproper belt tension is the leading cause of premature belt failure and increased costs. Under-tensioned belts lead to slippage, overheating, excessive pulley V Belt Tension Methods & Instructions: Easily Align PulleysUsing a spring scale, press down on the belt in the approximate center of the span, and deflect the belt to the desired level. When the desired deflection 
How to Tension a V-Belt (& How Not to)Feb 5, 2018 — The proper tension is the lowest tension at which the belt won't slip or squeal under peak load. However, there is still a wide range of tension proper belt tensioning - BestorqV-belts operate on friction; the friction is multiplied by the mechanical advantage of the wedging principle. Correct V-Belt tensioning is the single.
