I have attached 2 pdf's about constant S.
If you check the picture bolt 2 is adjustment bolt for constant s, garages most of the time fully tighten this bolt assuming that it is securing bolt causing constant s to be out. Normally this bolt is supposed to come out after adjustment and plastic protective cap to go in it's place. I have never seen it in practice and there is nothing wrong with leaving bolt in place as it's covered with thread lock and will not come out, it's just that it should not be fully tightened.
