campy ergo disassembly question

I've got a set of round-hood Mirage levers that have 1/2-1" of play in
the right finger lever before the shift click occurs. There also isn't
very much tactile feedback when shifting this way. The thumb lever is
fine and clicky (after I replaced the g-spring carrier a few months ago).

I've got it torn down as far as I can but can't figure out how to get
the lever pivot pin out so that I can get at the finger-lever assembly.
Is there a trick to this? Should I just squirt some oil in there and
realize that this is just the way Mirage's are?

Thanks for any insight!
