[pianotech] Young Chang damper upstop rail

[Tom Rhea, Jr.]

Thanks for your comment.  I was unsure of what was happening since I don’t
service grands all that much and have no experience with Young Chang.  The
church pianist plays rather exuberantly, shall we say, and had complained
that one of the notes (“middle C”) was ringing after the end of certain
loudly-played hymns.   My description of the problem was an educated guess
after listening to the symptoms and looking at a Young Chang schematic of
the instrument in question.

 

Your description – and that from Dean May – will go a long way toward my
resolution of the problem.

 

Many thanks to all from a fledgling neophyte – but learning fast –
technician.

List:

 

I need to adjust a Young Chang (circa 1991) Damper Upstop Rail that has
apparently slipped a bit and is allowing the dampers to rise between ¼ and ½
inch.  Can anyone give me some information on how to adjust the rail or
provide me with a place to look for information on the procedure.  Any help
at all will be greatly appreciated.

 

Thanks,

Tom

Your description is confusing. You say the damper upstop rail has slipped,
but that the dampers rise too far. If the damper upstop rail has slipped,
the dampers would not rise at all. I believe what has happened is that the
damper pedal has lifted all damper upstop rail too high. So there are two
steps to solving the problem. 

 

First you need to adjust the travel of the damper pedal so that when you
press a key with the damper pedal depressed, the dampers do not move. The
adjustment is a capstan like screw between the the trap lever and the bottom
of the keybed. 

 

Next, you need to adjust the upstop rail. The easiest way to adjust the
upstop rail, is to press 4 or 5 black keys and clip a clothes pin on the
damper heads, keeping them  raised up. Remove the action, and adjust the
upstop rail to the same height as the raised up dampers.
