It felt like it popped into position, and all the hammers lined up at the same height.

If the action is placed back in the piano in the same position as when it was removed the jack top to butt relationship should be unchanged. The main action rail and action mounting studs are untouched in the process.<o:p></o:p> I think you may have installed the hammer-butt assembly onto the flange and not matched the slot in butt with the center pin.  Essentially this will lower each hammer assembly pushing the shank off the rail and causing the hammer to block. Pull out one butt and flange, observe the slot and assemble correctly out of the piano. When I tighten the butt plate I move the butt until the center pin “snaps“ into the slot then tighten the plate. If I am correct when you put the assembly back in , there will be excessive lost motion and letoff on that note.<o:p></o:p> I can’t think of any other reason for such a drastic change in the key-action relationship.<o:p></o:p>  <o:p></o:p> This may be a good example of when to step back and figure out what has happened before readjusting everything.<o:p></o:p> I’ll be interested in what you find,<o:p></o:p> Best wishes,<o:p></o:p> Tom D.<o:p></o:p> <o:p> </o:p> <DIV> <DIV class=MsoNormal style="TEXT-ALIGN: center" align=center> <HR tabIndex=-1 align=center width="100%" SIZE=2> </DIV> From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of richard.ucci@att.net Sent: Sunday, August 31, 2008 11:08 AM To: pianotech Subject: spring loops<o:p></o:p></DIV> <o:p> </o:p> <DIV> List,<o:p></o:p></DIV> <DIV> Just completed  Yamaha spring loop replacement.
