DR
DRIVE BELTS - 5.9L DIESEL (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 (Objectional 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
