SHEAVE ALIGNMENT
Align the drive by the four-point method with a piece of string or a straight edge. The two sheaves will
be aligned when two points (near and far) on the face of each of the sheaves touch the straight edge
of the string when the string is a straight line. Refer to the fi gure below for correct alignment.
