MAINTENANCE
General Tensioning
Ideal tensioning is the lowest at which the belt will not slip under peak load conditions. Over-tensioning shortens belt and bearing life. Check
tension frequency during the first 24 hours of operation. Checks after jog start or one (1) to three (3) minutes of operation, at eight (8) hours,
24 hours, 100 hours, and periodically thereafter are recommended.
Keep belts free from foreign material that may cause slippage. Inspect the V-drive on a periodic basis. Under-tensioned belt drives often
produce audible squeaking noise, adjust belt tension when slipping.
NOTE
Do not apply belt dressing as this may lead to early belt failure. For proper tensioning, values and replacement frequency, refer to the manufac-
turer manual.
Sheave Maintenance
General Maintenance
Over time, friction between the sheave and the belt erodes sheave material lowering the efficiency. To maintain sheave efficiency, the sheave
should be replaced after the wall erosion reaches 1/32", as shown in the figure below. Typically after every five (5) to seven (7) annual belt
change.
