7 - 20 COOLING SYSTEM
DIAGNOSIS AND TESTING (Continued)
CONDITION
LONGITUDAL BELT
CRACKING
GROOVE JUMPING"
(Belt does not maintain
correct position on pulley)
BELT BROKEN
(Note: Identify and correct
problem before new belt is
installed)
NOISE
(Objectionable squeal,
squeak, or rumble is heard
or felt while drive belt is in
operation)
TENSION SHEETING
FABRIC FAILURE
(Woven fabric on outside,
circumference of belt has
cracked or separated from
body of belt)
CORD EDGE FAILURE
(Tensile member exposed
at edges of belt or
separated from belt body)
POSSIBLE CAUSES
1. Belt has mistracked from pulley
groove
2. Pulley groove tip has worn away
rubber to tensile member
1. Incorrect belt tension
2. Pulley(s) not within design tolerance
3. Foreign object(s) in grooves
4. Pulley misalignment
5. Belt cordline is broken
1. Incorrect belt tension
2. Tensile member damaged during belt
installation
3. Severe misalignment
4. Bracket, pulley, or bearing failure
1. Incorrect belt tension
2. Bearing noise
3. Belt misalignment
4. Belt to pulley mismatch
5. Driven component induced vibration
1. Tension sheeting contacting
stationary object
2. Excessive heat causing woven fabric
to age
3. Tension sheeting splice has fractured
1. Incorrect belt tension
2. Belt contacting stationary object
3. Pulley(s) out of tolerance
4. Insufficient adhesion between tensile
member and rubber matrix
CORRECTION
1. Replace belt
2. Replace belt
1. Inspect/Replace tensioner if
necessary
2. Replace pulley(s)
3. Remove foreign objects from grooves
4. Align component
5. Replace belt
1. Replace Inspect/Replace tensioner if
necessary
2. Replace belt
3. Align pulley(s)
4. Replace defective component and
belt
1. Inspect/Replace tensioner if
necessary
2. Locate and repair
3. Align belt/pulley(s)
4. Install correct belt
5. Locate defective driven component
and repair
1. Correct rubbing condition
2. Replace belt
3. Replace belt
1. Inspect/Replace tensioner if
necessary
2. Replace belt
3. Replace pulley
4. Replace belt
