Hello. 🌞 I am here to ask for a consultation regarding my piano, a Schulze Polmann that is more than fifteen years old, in which the sustain pedal (the one on the right) does not seem to be working. 😩
Today, having decided to investigate why the sustain was no longer working, I opened the panel underneath the piano and noticed that although the pin at the base was well inserted, the upper part was completely disconnected; so, I lifted that mechanical part (a small metal tube) and noticed that a part to which the metal mechanical part of the piano was most likely connected had become completely desoldered from it, and that a rubber tip was missing from the end—which I later found at the bottom of the piano case—(I am attaching a photo of the mechanical part).
I look forward to your feedback, thanking you in advance. 🤍
The photos are visible, but I can't quite understand what happened. Generally, the vertical rod ends at the top with a tip that goes into a perforated rubber piece. It seems to me that we are okay up to this point. At the bottom, it should connect to the horizontal rod with another free pin in a hole on the horizontal rod.
Hello. Thank you for your help. As I was writing previously, the rod seems to be desoldered from the internal mechanism, as seen in the fourth photo. The pin you are referring to is the one inside the case, right near the top, which is practically the segment following the desoldered part. I don't think it will be possible to recover that piece. Will I be forced to call a technician? Thank you in advance
I believe so. It needs to be seen up close and, if necessary, order the part or create a new lever transmission. If it has come unsoldered, it must be disassembled and taken to be soldered (sometimes these rods are made of metal alloy and a simple solder won't hold... but it all remains to be seen. Either it is soldered or it is drilled and a gasketed shaft is made to avoid any noise. We need to see what system was used. Anyway, I sent you a private message with my numbers. If you want, call me.
