[CAUT] Today's Puzzler.

You might be able to remove the screws in the guide rail and loosen the
guide rails from the soundboard (they usually stick a little).  Then
remove the screws from the damper tray blocks.  Remove the sostenuto
rod.  Raise the stop rail as high as it will go.  Then pull the whole
assembly forward (carefully) so as to expose the spring and underlever
assembly.  Make your repairs, push it back in and resecure.  If that
doesn't work you will have to remove the dampers and pull the tray.

Colleagues,

Thanks for the suggestions that have been generated from this post. 
Here's the problem:

to the plate because of the break and you're scared to shim it. >

..and that's about as close as it gets. I have only seen this type of 
configuration once before..there is no way to remove an individual 
underlever..or at least no way that I was able to see.

It looks like a broken upright damper spring on its side. The click is 
coming from the spring because it has become dislodged from its 
groove..or it's broken. Since it was B2, I was able to see it rather 
clearly and replicate accurately.

Is there a way to remove an single underlever without a screw visible? 
There's 2 large ones at either end of the damper tray...

Again, thanks for the replies.

-Phil
