Dirt, the link on my Atlantis seems to be sloppy -- the little bakelite link at the top of the plunger can slide back and forth too much (I believe) on that post between the little "c" clip and the side of the mechanism. As far as I can tell, that's the only part that's worn out. The rest looks good to me. Should I just replace the plunger/link or the whole assembly to be safe?
