<DIV><FONT face="Bookman Old Style">Some diagnosis can be done without rem=
oving the action. Quick test: Depress damper pedal and release. Lightly push=
down on hung damper head. If it returns with a light snap or won't go down,=
the sostenuto tab is rising past the sostenuto rail, probably because the d=
amper PEDAL stop (not just the upstop rail) is allowing the damper peda=
l to take the dampers too high. On Steinways, you can confirm by pulling act=
ion out 1/8 inch and trying again. Because the sostenuto is on the key actio=
n, the damper will now not hang.</FONT></DIV>
<DIV><FONT face="Bookman Old Style"></FONT> </DIV>
<DIV><FONT face="Bookman Old Style">If on the other hand it hangs when usi=
ng the key, the damper upstop rail is probably too high, allowing the tab to=
blow by the rod.</FONT></DIV>
<DIV><FONT face="Bookman Old Style"></FONT> </DIV>
<DIV><FONT face="Bookman Old Style">If the damper does not snap, but goes =
down with steady resistance, you can then go after friction in the underleve=
r flange, top flange, or bushing. First, play the note. Push the head lightl=
y to left and right. If it moves one way, the bushing is PROBABLY free. You =
can develop a feel for how much it is sprung against the bushing. If it flun=
ks or is inconclusive, THEN you can remove the action. </FONT></DIV>

<DIV><FONT face="Bookman Old Style">Lift the underlever with one finger. Y=
ou can feel friction. With one finger of the other hand, press the wire gent=
ly left/right, right under the bushing. One way it will move with you, off t=
he bushing. The other way it won't. If it moves opposite your push both ways=
, the bushing is probably too tight. If not, then you can remove the wire an=
d check for top flange friction and mount flange friction. Last resort take =
out the underlever. It takes longer to describe than to do.</FONT></DIV>
