How important are the tension setting and alignment of the timing belt?
The tension is a crucial factor in attaining the normal change interval. Insufficient tension overtaxes the teeth and can cause the belt to fail as a result of torn teeth. Excessively high tension is usually indicated by a typical sound while the belt is running and can usually be corrected in time before failure occurs due to overload. Incorrect alignment of the belt drive can cause the belt to chafe sideward against a flanged pulley or covering. This will lead to corresponding wear and eventually cause premature failure (belt rupture due to insufficient width).
