CONDITION POSSIBLE CAUSES CORRECTION
LONGITUDAL BELT
CRACKING
1. Belt has mistracked from pulley
groove
1. Replace belt
2. Pulley groove tip has worn away
rubber to tensile member
2. Replace belt
9GROOVE JUMPING”
(Belt does not maintain
correct position on pulley)
1. Incorrect belt tension 1. Inspect/Replace tensioner if
necessary
2. Pulley(s) not within design tolerance 2. Replace pulley(s)
3. Foreign object(s) in grooves 3. Remove foreign objects from grooves
4. Pulley misalignment 4. Align component
5. Belt cordline is broken 5. Replace belt
BELT BROKEN
(Note: Identify and correct
problem before new belt is
installed)
1. Incorrect belt tension 1. Replace Inspect/Replace tensioner if
necessary
2. Tensile member damaged during belt
installation
2. Replace belt
3. Severe misalignment 3. Align pulley(s)
4. Bracket, pulley, or bearing failure 4. Replace defective component and
belt
NOISE
(Objectionable squeal,
squeak, or rumble is heard
or felt while drive belt is in
operation)
1. Incorrect belt tension 1. Inspect/Replace tensioner if
necessary
2. Bearing noise 2. Locate and repair
3. Belt misalignment 3. Align belt/pulley(s)
4. Belt to pulley mismatch 4. Install correct belt
5. Driven component induced vibration 5. Locate defective driven component
and repair
TENSION SHEETING
FABRIC FAILURE
(Woven fabric on outside,
circumference of belt has
cracked or separated from
body of belt)
1. Tension sheeting contacting
stationary object
1. Correct rubbing condition
2. Excessive heat causing woven fabric
to age
2. Replace belt
3. Tension sheeting splice has fractured 3. Replace belt
CORD EDGE FAILURE
(Tensile member exposed
at edges of belt or
separated from belt body)
1. Incorrect belt tension 1. Inspect/Replace tensioner if
necessary
2. Belt contacting stationary object 2. Replace belt
3. Pulley(s) out of tolerance 3. Replace pulley
4. Insufficient adhesion between tensile
member and rubber matrix
4. Replace belt
