I have an otherwise beautiful Yashinon 50mm f/1.4 that has some separation issues in the cemented doublet in the rear group. Problem is, for the life of me, I can't figure out how to remove this doublet form its brass mount. It looks like there might be a press ring holding it in form the front, but I've had no success in getting it to move, and it might be just a lip in the mount. If that's the case, I imagine it's glued in form the rear, but I have had no success with heat, acetone/MEK soak, etc.
Does anyone have any clue how to get this apart?
I found a disassembly guide on Flickr, but this guy doesn't seem to have been able to get it apart ither:

The doublet in its mount can be seen on the right.
