3.4.2.4 Determine misalignment and correct vertical plane
Before moving the equipment vertically, it is important that the vertical thermal expansion be taken into
consideration. Refer to General Arrangement Drawing notes and/or driver instructions for recommended cold
vertical setting (if thermal expansion is a factor).
The shims between the motor feet and mounting surface should be clean and dry. This is especially critical for
equipment that has been in service for some time and need to be realigned. Do not use many thin shims, as this
may result in a spongy mounting.

3.4.2.5 Determine misalignment and correct horizontal plane
The dial indicators shown below are required to accurately measure the move in the horizontal direction. Move
the driver by bumping with soft hammer/mallet or using the jack-screws (if provided). The amount of horizontal
relocation required is calculated in alignment data sheet.

NOTE
It is recommended, the completed alignment document be retained as part of your
permanent maintenance file.
3.4.3 Laser alignment
The use of laser alignment greatly simplifies the alignment process. Because of equipment and software
differences, this will only describe laser alignment in general steps.
