I will have to try removing that retaining ring and go from there.
Yes, that's the only way to get to the bottom of this. Once the retaining ring is gone, the shaft should slide out the other end easily. Then you'll be left with a plastic dog that's either cracked into 2 parts, or busted into a dozen pieces. It will take some effort to get everything out of there, including the spring that won't be helping matters. Try to get an idea of the orientation of the dog as you get the pieces out. The dog body has a long and short end; that is, the actual drive dogs are closer to one end of the body.

If the dog is simply broken into 2 halves, I suppose it might be possible to glue it back together on the shaft, but I hate to resort to fragile repairs on something so difficult to get to. That's why I went with the brass replacements.
