Problem:
Covers swell in spots or streaks
Cause:
Spilled oil or grease; over-lubrication of idlers
Solutions:
Improve house keeping; reduce quantity of grease used; check grease seals
Problem:
Belt breaks at or behind fasteners; fasteners pull out
Cause:
Fastener plates too long for pulley size
Solutions:
Replace with smaller fasteners; increase pulley size
Cause:
Wrong type of fastener; fasteners too tight or too loose
Solutions:
Use proper fasteners and splice technique; set up schedule for fastener inspection
Cause:
Tension too high
Solutions:
Increase belt speed, same tonnage; reduce tonnage, maintain same belt speed; reduce friction with better
maintenance and replacement of damaged idlers; decrease tension by increasing arc of contact or go to lagged
pulley; reduce the counterweight to minimum amount
Cause:
Heat or chemical damage
Solutions:
Use belt designed for specific conditions
Problem:
Vulcanized splice separation
Cause:
Belt improperly spliced
Solutions:
Re-splice using proper method as recommended by Continental ContiTech
Cause:
Pulleys too small
Solutions:
Use larger-diameter pulleys
Cause:
Tension too high
Solutions:
Increase belt speed, same tonnage; reduce tonnage, maintain same belt speed; reduce friction with better maintenance and
replacement of damaged idlers; decrease tension by increasing arc of contact or go to lagged pulley; reduce the counter-
weight to minimum amount
Cause:
Material trapped between belt and pulley
Solutions:
Install plows or scrapers on return run ahead of the tail pulley
