Reply to "should alignment readings are to be taken in tight foot bolts condition?"

"It is always advisable to take reading at tight bolt condition because while tightening it may turn slightly the motor because bolt can foul wioth the shim what you have fixed for alignment or bolt may touch with the motor body which can turn the motor. Full tight of the bolt while taking reading is always advisable."
hi Roy
thanks for reply. Take the case pump is in misaligned condition. Now I have taken readings in tight bolt condition. from these readings shim thichkness is calculated. Now for inserting shims below foots one have loose bolts again, so chances of motor movement is there. I think if soft foot is correct in well withinn range than there is no effect on alignment weather bolts are tight or loose during measurement because if soft foot is corrected than shims could not compressed/pressed due to tightening.May plz guide further.
