9.9.1 Inspecting the Belt

Remove the pulley cover and visually inspect the belt.
Durability of the reduction belt is affected significantly by the operating condition, and there is no standard
guideline as to when the belt should be replaced.
Generally, the belt is designed to withstand several millions of flexing loads.
As a practical guideline, replace the reduction belt when any of the conditions listed below are observed:
• The teeth and end faces of the belt have worn significantly.
• The belt has swollen due to deposits of oil, etc.
• Cracks and other damages are found on the teeth or back of the belt.
• The belt has broken.
