operation may require the full coupling misalignment
There are two types of shaft misalignment: Angular
and offset. Both types of misalignment can occur in
horizontal and vertical planes and are present in most
In angular misalignment, the centerline of the shafts
intersects, but is not on the same axis.
In offset misalignment, the shaft centerlines are
parallel but do not intersect.
The following methods may be used to align
equipment train. The methods a) and b) are dial
Reverse rim indicator alignment
Soft foot can affect the alignment readings and
should be checked first and eliminated on both pump
and check if there is a indicator reading. If so
place a shim with the same thickness as the
