Dear "swirsky,"

      Try using your centerpin-extracting pliers. If you can raise the
underlever enough to expose the offending lead weight, and if you can
reach it with the centerpin extractor, just squeeze the pliers with the tip
of the extracting pin against the weight. This will make an impression in
the lead and cause the weight to expand slightly and become tight in the
hole. I've had good luck with this method whenever I've actually been
able to reach the lead weight with the tool.
      If you're unable to reach the leads, then I'd recommend removing
the damper action and swaging each weight at the workbench.
      Good luck!
