Drive Belt Routing: Description

Many manufacturers are converting to single ("serpentine" or "V" ribbed) belt systems to drive components normally requiring multiple "V" belts. The serpentine belt system incorporates a tensioner. The tensioner makes it possible to rigidly mount belt-driven components previously requiring individual belt adjustment. The tensioner controls belt tension over a wide range of belt lengths, but cannot compensate for extreme belt lengths. Poor tension control or possible tensioner damage can result from excessive length belts.
