1. To check, use straightedge or string near sheave centers.
2.
To correct, loosen sheave and relocate on shaft until all four points touch straightedge. Tighten sheave in
position.
IMPORTANT: Sheave should be mounted as close to bearing as possible to reduce overhung
load on bearing. Relocate equipment, if necessary.
NOTE:
Never “pry” the belts into the sheave grooves. This can damage the belt cords and lead to belt turnover,
short life or actual breakage.
