VA
CONDITION
LONGITUDAL BELT CRACKING
GROOVE JUMPING"
(Belt does not maintain correct po-
sition on pulley)
BELT BROKEN
(Note: Identify and correct problem
before new belt is installed)
NOISE (Objectional squeal,
squeek, or rumble is heard or felt
while drive belt is in operation)
TENSION SHEETING FABRIC
FAILURE
(Woven fabric on outside, circum-
ference of belt has cracked or sep-
arated 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 toler-
ance
3. Foreign object(s) in grooves
4. Pulley misalignment
5. Belt cordline is broken
1. Incorrect belt tension
2. Tensile member damaged dur-
ing belt installation
3. Severe misalignment
4. Bracket, pulley, or bearing fail-
ure
1. Incorrect belt tension
2. Bearing noise
3. Belt misalignment
4. Belt to pulley mismatch
5. Driven component induced vi-
bration
6. System resonent frequency in-
duced vibration
1. Tension sheeting contacting sta-
tionary 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
