If you lift the damper tray by hand you hear the squeak. If you lift individual underlevers (either by hand or with the keys)) there is no squeak. But the problem was not with the damper tray mechanism. I lifted each underlever  and operated the pedal. Finally I found one damper when lifted out of the way, the squeak was gone. But if you lift that damper by hand there was no squeak. However  you could hear a very slight rubbing sound from the bushing, which its neighbors did not have. You had to listen incredibly carefully. I polished the damper wire with Flitz and applied McLube to the wire. The squeak was gone.   I guess there was a resonance created only when the underlever is lifted at is capstan, and the resonance was damped when the underlever is lifted at the spoon.   I think the Young Chang has a similar system with capstans for damper tray lift and spoons for key lift. I don’t know if this is your problem, but it’s worth checking before dismantling the damper tray mechanism.   Jerry Cohen, RPT New Jersey Chapter   -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Paul Chick (Earthlink) Sent: Wednesday, September 14, 2005 6:02 PM To: Pianotech@Ptg.Org Subject: Squeeky damper tray   List Members:   A Young Chang G175 has a squeak in the damper tray.  All the moving parts of the sustain feature in the piano were eliminated until the tray.  Before disassembly, I thought I’d seek the wisdom of the list to learn if anyone has encountered this problem, and what was done to solve it.  It sure sounds like the groaning squeak you hear from tight cloth bushings against a metal pin.   Paul C </div> </body> </html>
