Gouged Edge
A gouged edge in a belt can be caused by a damaged
pulley, a misaligned pulley, or the belt being too loose
or too long. Check the pulley and the belt for proper
alignment and tension. Make sure other components
are not misaligned and rubbing against the belt.
Worn Sides
Belts that are worn on the sides are probably too
loose. The pulley may also be misaligned. Install a
new belt and adjust properly. Check for a worn or
misaligned pulley.
Excessive Stretch
A belt that is stretched beyond adjustment is usually
the wrong size or is adjusted too tight.
Replace the belt and adjust the tension.
Flat Spots
Flat spots may result by not relieving the belt tension
while storing the vehicle or engine. A temporary
vibration will occur when the engine is first started. Flat
spots are most noticeable with variable speed drives.
Flat spots may disappear during normal engine
operation. If the flat spots remain, replace the belts.
Internal Cord Damage
Cords may be broken by prying the belt onto the pulley
or debris on the pulley. Internal cord damage will
cause the belt to roll out of the pulley groove.
Replace the belt and adjust properly.
