c. Pulling: Belt material is sheared off from the ribs. Lack of tension, misalignment, worn pulleys or a
combination of these are factors.
d. Uneven rib wear: Belt shows damage to the side with the possibility of breaks in the tensile cord or
jagged edged ribs. A thumping/grinding noise may also be heard when running.
e. Improper installation: A belt rib begins separating from the strands. If left unattended, the panel will
often separate, causing the belt to unravel.
f. Cracking: Small visible cracks along the length of a rib or ribs. With continuous exposure to high
temperatures, the stress of bending around the pulley leads to cracking.
g. Misalignment: Sidewalls of the belt may appear glazed or the edge cord may become frayed. A
noticeable noise may result.
h. Gravel penetration: Small pinholes are visible on the backside of the belt. Bumps may be visible and
fabric around the holes can be frayed, indicating damage from foreign objects such as dirt, gravel or
similar debris.
