[pianotech] Baldwin Pedal with squeaky rubber grommet

[Loren Kelley]

Thank you for the suggestions Tom.  At this point it's pretty clear I should schedule time to disassemble the lyre.  I like the idea of replacing the rubber with a leather pocket.

  Lauren,
    With a recurring problem as described by the customer there is a good argument for an R and R of the lyre to disassemble and recondition,including the trap lever springs, leather ,pitman right on up to the tray and even the damper guide rail bushings. 
  That being said, if it squeaked and lubing the rod pedal interface stopped the noise I'm guessing you have found the problem. Protek would be my first arrow at this dartboard and maybe VJ . 
  Big picture --- If you lube the thing and it comes back then you're in the group of "other techs"   I would suggest to the client that lubing the pedal may hold off the noise for a while, but that you suggest reconditioning or at least modifying that setup is what the piano is telling you to do.
   To that point and your question removing the pin may be more than the center pin tool should try. After removing the pedals I would use a pin punch and a wooden block with a hole to support the pedal-------or you might be able to pull the pin out with a vicegrip with everything in place. I would consider losing the pin setup and creating a leather pocket in the pedal and lubing the inside with VJ.
   Correct this problem and you are separated from the "other techs" and I'm guessing an action recondition - regulation job will be an easy sell .

    Hello Everyone ~

    I'm new to this list. It's fun to read all the stuff that goes back and 
    forth.

    Last month I tuned a Baldwin Grand (dang, I didn't get the serial #) that 
    had a pedal noise. The damper pedal had a sort of squeak where the lift rod 
    sits in a rubber grommet. I could not lift the rod out of the grommet 
    because there was a pin holding it in, like a center pin. I wanted to 
    remove it so I could do a good job of lubricating it, but no luck. I tried 
    to use my center pin tool, but the other pedal was too close and interfered. 
    I ended up spraying dry teflon into it as I flexed it, trying to help the 
    stuff get down into the grommet. It worked at the time, but the customer 
    called back recently and said the sound was back. She said that other techs 
    had fixed it before, but it comes back. I'm guessing they had the same 
    problem I did.

    Perhaps it is necessary to remove the pedal lyre and disassemble it, remove 
    the pedal and then use the centerpin tool on it?

    Anybody dealt with this before? Any ideas for getting the pin out in order 
    to remove the lift rod?
