Good point! For thoes of us that have done 30 or so of them.....its like DUAH!!! But we have to remember the 1st timer........that would be a rough first pump install......ALSO remember to get the key way at the 12 O'clock position on the shaft before you try to remove the pump...or you might be doing the same thing with something about 1/10th the size of the washer......not sure if that has been brought up or not yet.....
