Simon >Phoenix Rather than spin the plastic nuts on and off, you might try unhooking the wire lifter from where it connects to the wippen. 1. Remove wire carefully from wippen and back of key 2. Silde the old grommet down and off the wire 3. Put new grommet onto wire and slide up into place 4. Connect the lifter wire to the key 5. Carefully push the lifter wire back into the wippen 6. Adjust for lost motion I've done this job both ways and for me, it was much faster to use this method. Figure on a couple of hours, more or less. Good luck.
