Bill's solution may be best…
Bill's solution may be best but it's not possible without the machinery. And when I once tried to remove the bush, I gave up.
I use an x ring and it's far better than o ring. I filled the groove behind the ring with silicone and assembled it. The groove is too big for the ring otherwise. In fact I did buy the 'correct' o ring some years earlier, and that was a loose fit also. I don't know if it' was the wrong size or if the box is wrong but I don't believe it is.
Have others had the same issue? Is the ring (x or o) always supposed to be glued in?

Firstly I would replace the K/S shaft bush A2/364 Then on the inside of the inner cover machine enough of the bush away to fit the seal. Also check the K/S shaft for wear and build it up with bronze or get it metal sprayed and re machine it. Good Luck.
