When performing shaft alignment, the best way to accomplish the horizontal (side-to-side) corrections is using jack bolts. You do not want to hit your machines with a hammer in order to move them. Always remember to back off the jack bolts on the opposite side. Remember that once you are done with your side-to-side correction, we recommend that you always back off all jack bolts after the alignment is completed and the anchor bolts are tight.

WHERE TO PUT THE JACK BOLTS ON YOUR MACHINE?

Place the jack bolts in such a way that they do not interfere with the shimming and allow you to pivot the machine you are moving. See figures 1 and 2 below.
