When loosening the adjusters remember that both sides turn in opposite directions to loosen them. For removing and installing the lock ring a pair of snap ring pliers allow you to get a grip on them normally. If that doesn't work a set of pics can be used to hook behind it to get it loose. When installing the ring back on you normally do not have to adjust the nut. If the pin doesn't line up when you try to put the ring on then pull the ring out and turn it over and then put it back in. (The holes in the ring are aligned specifically so it can be turned over to change the position of them without adjusting the nut) There is enough adjustment back and forth that it will almost always go in one way or the other.
