New Center Pin Design

Hi Terry,
This Yamaha, probably has the plates with a screw to hold the pin in place.
These screws should be snugged up, to stop the pin from wandering.
It is not so much a loose pin that is causing the problem, it is the loose plate.
Sometimes the pins can just be pushed back in place with no damage, if you loosen the plate a bit more.
Then just tighten the screw. Problem solved without repining.

  That was actually the problem. When I first saw it I figured the guy chewed up the flange bushings with this innovation, but I repinned it with an 0.048" pin - so no enlargement there. The long unclipped end interferring with the hammer shank wanting to return to the rest postion is what caused the inoperable key. I could see that at least half of the hammer flange center pins were walking out of their proper postition on this piano - presumably I'll have a repinning and general action refurbishing job on the piano. This particular piano was the worst Yamaha I have ever tuned with respect to stray string noise (my experience is that Yamahas are usually a pleasure to tune) - more like tuning a Kimball console (false beats and unisons that would just not come clean - I hate that).

    you gotta love it... ... the fellow / gal was clever enough to screw the darned thing out and put it in again.... but not clever enough to snip off the leftover clip... wunerful...:)

      Great new center pin design. This (below) was recovered from a 35-year old Yamaha console. One key didn't seem to be working....... I'm all for improvising, but this is ridiculous! Terry Farrell
