B2 piston removal

[Marc]

Ok, so I had all the symptoms of the infamous B2 piston failure. I pulled the cover off and out fell most of the pieces. However, the larger disc that is part of the piston is jammed in the case. I've read all of the replacement procedures that I've found. None of them mention this. They just say remove and replace the piston and sleeve. I'm sure this has to be a common problem with this failure. Anyone have any experience on getting this part out.

Oh, BTW if it matters and I don't see why it would. This is a 1983 sl500 euro.

Thanks for any and all help, much appreciated.
