Rex,

Unless you are one of the lucky few who has just the right screwdriver to get in there, you do have to pull the damper action forward to tighten these screws or repair the damper tray flanges or blocks.  You do not have to remove or loosen the damper wires.

- Remove sostenuto rod from the hangers (leave hangers in place)
- Raise upstops all the way
- Remove the trap lever  and pitman dowel
- Remove the screws that hold the damper rail to the belly
- Lift the tray up to get the dampers off the strings, and ease the damper action forward until you can get a long screwdriver down between the strings, or a short one from underneath, and service the damper tray blocks.
- Reverse the above to re-install the action.

  Thank you for your responses. The problem that I am having is that the flange is in front of the screw and the damper lifter tray doesn't drop far enough to access the screw behind the flange. If I could get to the screw, I have a couple of tools that I could try to use to hold it to start it, but the way things are now, there is no way to get a straight sighting on the screw. The ones on the end can be reached from the end by going around the flange, but the one in the middle has the sostenuto bracket and the flange in the way. The screw cannot even be seen from the front. I only found it by reaching under and behind the tray (between the tray and the flange rail.) There was no room to get my fingers in to put the screw back in the hole, and no way to get it out. Right now it is resting so it doesn't interfere, but that most likely is not going to stay the case.



  From suggestions I have thought of, coupled with some from off list I would have to:



    1.. Dismount the Sostenuto and drop it out of the way and/or 
    2.. Get the actions dogs and the sostenuto spring mounting blocks unscrewed from the keybed using an offset screwdriver and hope the tray drops far enough to access past the flange. (Dogs and mounts are again screwed to the keybed form the top directly under the damper tray. No direct shot for a screw driver.) 
    3.. Remove the keybed and again hope that the damper tray drops far enough to access the screw. 


  Don't like any of these ideas to just get one screw out of (or back into) a back action flange.



  Thanks again for the help.
