By removing one of the pivot pins, it’s pretty easy to open a derailleur flat and clean all the gross stuff out of the inside. In this case, crud had accumulated in the spring’s coils and was preventing it from retracting fully, messing up my shifting.

The trick to getting a pin out of most Shimano derailleurs is to drill a small hole in from the blind side of the pin’s hole. Use a small punch (I machined one from a drywall screw) to tap the pin out of the hole backwards until you can extract it with pliers. When reinstalling the pin, peen the original opening over slightly to retain the rivet. I think I used a small straight screwdriver and a few taps of a hammer to create the necessary burr.

The last coils mounting point, solder removed from the holes, cleaned and ready for the modified coil.

Also note how the caps and resistors seem to have more than the usual amount of solder holding them down? I reinforce those joints while the coils are out, and clean with solvent to remove the flux.
