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. Never prize the belts with a screw-
driver or other tool.
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.
