Symptom
Possible reasons
Correction

body)-
Chunking happens
when several cracks in one
area of rib move parallel to
the cord line.
1. Foreign objects embedded
in pulley groove
2. Installation damage.
3. Poor surface of grooves in
pulley.

Remove foreign objects from
pulley grooves. Replace belt

Piling- happens when the
material is sheared off the
undercord and builds up in
the groove.
1. Lack of tension
2. Misalignment of pulleys
3. Worn out pulleys
4. Excessive tension.

Adjust tension
