Where sheaves carry more than one belt, never replace only
one belt. If any belt must be replaced, replace all the belts with
new ones. When replacing multiple belts use only new belts
from the same manufacturer and the same lot number, or use
matched belts. Failure to do this will result in severe belt wear.
When removing or replacing belts, always relieve the belt ten-
sion to position the belts. Severe belt damage and reduction of
belt life can be caused by prising or walking a belt onto a
sheave.
Belt sheaves must be properly aligned, as shown below.
While the sheaves were aligned at the factory, future adjust-
ments may cause varying degrees of misalignment. A common
problem is parallel misalignment, as shown below. Parallel mis-
alignment causes excessive belt, sheave, and bearing wear.
Another common problem is angular misalignment, as shown
below. Angular misalignment causes excessive belt, sheave,
and bearing wear.
