Horizontal Angular
(Shafts in same horizontal plane but not parallel)
1. To check, use straightedge or string near sheave centers.
2. To correct, loosen motor mounting bolts and rotate motor until all four points touch straightedge.
Vertical Angular
(Shafts in same vertical plane but not parallel)
1. To check, place straightedge 1/4 radius from the outside diameter of both sheaves as shown:
a) Repeat on opposite side of shaft.
b) Straightedge should touch four points indicated in each position.
2.
To correct, loosen sheave so it slides easily 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.
