dryer belt diagram

Belt Was Off The Drum But Not Broken. We Put The Belt Back On The Drum, Then Motor Pulley Then Idler Pulley Like We Were Supposed To But The Belt Was Still Too Long. Is It Possible The Belt Had Just Stretched? Would Like To See A Diagram On How To Install The Belt Correctly On My Model Electric Dryer.

This may help
