related bushing.

Nope. You're not even warm.

...wood broken away in the keyframe where the una-chorda lever is =
supposed to engage.

That ocurred to me also. I checked that and the underside of the =
keyframe appears all original and in excellent condition. There is a =
hard maple insert with a leather pad where the una-corda level should =
contact. All appears well with the keyframe.

But like Alan Barnard, you are in the right ballpark, but this is not =
the correct answer.

  Close?

    About 1980 Kawai KG-2S - about 5' 10" - very good to excellent =
condition. Lady bought it used one year ago (she paid $3,500 for it - =
perfect satin cherry case - she got a great deal!). During that first =
year she had a QRS Pianomation player system installed on the piano. We =
had set up a service appointment for cleaning the interior, tuning and =
looking at a "loose" pedal.

    The left (una-corda) pedal was just hanging down. I crawled under =
piano to check levers, etc. Everything with the una-corda under the =
keybed appeared to be functioning just fine. Adjustment appears good (in =
that, when the pedal travels down, the lever moves sideways in the =
keybed). However, when you depress the left pedal the action frame did =
not slide over to the right. The keyframe was resting on the left felted =
keyframe stop. The action slid in and out easily. It was as if the =
una-corda lever system was not hooked up to the action frame.

    What was the cause of the non-functioning una-corda pedal?
    =20
    (This is probably too easy - however, it did take me a good 10 or 15 =
minutes to fully figure it out.)
