The first pic is mine, the rest from the net. I have more than the 4 in the original pc of this style. I was able to get only 1 apart without wacking on the slots in the lock ring with a hammer, punch, screwdriver, whatever. I have soaked this style for months, but it needs force to unscrew the ring if it is screwed on tight. Either it will unscrew easily on the first attempt, or it will not. I do not think Loc-Tite is an issue because I do not think it was used. I think they were screwed on very hard at the factory, and the threads are a fine pitch. If you are lucky enough to remove the ring, then you must tighten it as much as you can when you put it back together, or the ring can unscrew with you operate the ratchet.
If you wack on it then it can damage whichever of the 4 slots you are hitting on, and then the slots look like crap.
I would like to find a more elegant solution some day. It is like a gland nut. You would need 3 different sizes. The last 3 picture are what I saved from the net of what a proper tool would look like.
