Belt Maintenance
Sheaves - Inspect
• Damaged, worn or dirty sheaves (1) will
substantially reduce belt life.
• Nicks or gouges can cut the belt.
• Dirt in the grooves can damage t
he belt and will allow the belt to bottom out, slip
and become damaged.
• A sheave groove gauge can be used to de
termine uneven and abnormal wear.
NOTICE: When placing
the new belt in the groove, the top of the belt should be flush
with the outer diameter of the sheave. If the belt top is below the outer diameter of
the sheave, the groove is worn.
WARNING: Do not clean the sheaves while the machine is running. Shut off engine before removing
or installing sheaves. Take sheaves off machines to inspect, clean and repair them.
WARNING: Do not install damaged or worn sheaves on equipment. Repair or replace them.
