Greetings, 
   I assume this is the white plastic glued bushings?  if so, then heat is 
about the only thing that will soften this glue for long enough to take the 
bushings out.  I use a homemade steamer.  If you use a de-bushing iron, the 
felt needs to be wet so that the heat will reach the glue before the bushing 
burns up.  Once the temp. is really high in the cloth, you have to get the 
cloth out in a hurry or the glue will set right back up.  
  I normally use hot hide glue to rebush with, but on sets of the mid-60's 
Steinways that have this thermoplastic glue, I found that a number of 
bushings wouldn't stay adhered.  The surface of the wood seems impervious to 
hide glues adhesion.   I believe that PVC-E glue would be my choice to 
replace the felt with, since it seems to stick to anything.  
Good luck, these sets take about twice as long to remove as any other I have 
seen.
