Hello, I have a pump where the spacer slightly moves to the left and right between the two couplings IS THAT NORMAL? OR SHOULD THE SPACER NOT MOVE AT ALL?

[@lingeshwaranb28]

What is the type of coupling being used?

... Did you just use a ruler to check alignment? if you manufacture API equipment please have your clients use a dial or laser. Based on RPM you should be aiming for .05-.09 mil angular and 1-1.5 mil offset. Also is this doweled, flat faced or a spigot? Even a spigot can have a .005"-.0020" slop. Don't for get to check you TIR at the shaft closet to the coupling to ensure you have done the alignment correct

Why can't you install the motor side coupling beforehand

I don't think so,it will give you correct alignment.... It's just a rough alignment..
