Yamaha G3

[Dean May]

I'm not familiar with this particular model, but I have done screws in
similar situations. You can get screwdrivers that hold the screw on the end
while you stick it into inaccessible places. In a pinch you can also super
glue the screw to the end of your screwdriver. Once you start putting torque
on it it will break loose.

Dear List

 

I have a problem with a Yamaha G3 grand. The flange screw for the center
damper lifter tray flange has come loose and is out of its hole. (This is
the screw that holds the flange to the damper flange rail, not the screw
that attaches it to the damper lifter tray.) When it works its way around it
gets between the damper tray and the damper flange rail and holds the tray
up just enough for the bass most dampers to not stop the strings correctly.
I remember seeing descriptions on this list for a tool to tighten the end
flange screws, but I'm not sure if this can get to the center flange screw.
The screw is not just loose where it can be just tightened; I am going to
have to get it restarted into the aluminum flange rail.

 

Even if the entire back action was disassembled, I don't see anyway that
this screw could ever have been installed to begin with unless it was put in
before the keybed was installed. Any and all help will be much appreciated.

 

Thanks
