"Felt covered rods?  I'm totally lost.  Without the weight of the dampers?  I'm confused too.  The last thing you want to touch back there is the set screw that secures the bottom of the damper wire to the damper lever assembly.  That's the one that's can be bear to get back into position.  Trust me, it's not as easy as you think.  It looks that easy, but it isn't.  You can give those set screws a check to be sure they're not loose, but don't even try tightening them.  That can be enough to change their position, and it doesn't take much to give you a ringing damper.  If the dampers work, leave them alone.   \nThe back ends of the keys are notched and have nice felt cushions that sit under the damper levers.  With the action out, lift the damper levers with your fingers and let go.  Do they fall freely?  If so, you're good there.  Be grateful for that.   \nI guessing late here that you're hip to the risk of ripping off hammers with the pinblock when you remove the action.  Also, never strike a key if there is no string or letoff rack to stop the hammer travel.  That'll break 'em off at the other end.   \nPull out one of the sluggish hammers and give it the swing test.  I'm guessing from your description that you'll get a tick and perhaps half a tock.  With the hammers lifted out of the way, flick the jacks and the rep levers.  They are spring loaded and ought to snap right back when released.    \nThere are two rules for key easing.  Don't overdo it and don't split keys.  If you've got a good system for doing that, easing the action centers might not be beyond you either.  It'd be a lot easier to offer a little phone support to cover the procedure, caveats, risks and rewards than trying to type it all out.     "
