If the old lube has become thick and gunky you may be able to wash it out

For cleaning all the grease and junk out of anything, get Brake Clean from
the auto parts store. Works great on all sorts of mechanisms. There will be
no lube left, you'll have to re-lube after it dries.

CAUTION: There may not be any plastic gears or cams left intact,
either. Some solvents used as "Brake Cleaner" are very aggressive to
plastics, and newer sewing machines have lots of plastic parts.
