V Twin Crank Removal

I'm in the middle of a crank swap in my 88", I'm building a 103 for a little more go power. I've got the engine cases cracked and the right side removed. The crank doesn't seem to want to be removed from the left side case, I don't see any keepers or snap rings, am I missing something or did the damn thing grow roots. I've got that half of the case in a 12 ton press but I'm a little afraid to put any real pressure on it for fear that it might break. Any suggestions out there.
