At the time, the bolts had already been installed by someone else to hold the damper pedal down, and I tightened the screws for the (right side) damper trap lever assembly to keep it from blasting off. Miracle cure! Ah, but there was still noise, I treated the damper spring felts with Protek--which seemed to take care of the squeaks. I was hoping that would be the other miracle cure. I went back to take a picture of the pedal assembly, which is a little different. The damper pedal pulls down two levers--one to the right, tenor & treble, and one to the left, the bass. Could it be this set-up that makes the pedal feel somewhat stiff? It would make sense, since two trap lever springs are being pushed down. I didn't notice a stiff damper spring feel in the action itself (after I lubed the spring felt). When I went back to take the picture last week, I noticed that the squeaking is back. I'll admit it, I was in a hurry and didn't take a close look at the felts. I suppose cleaning the damper springs and replacing the spring felt is next. Is there a different (faster) solution--like some miracle lubricant I haven't heard of that came on the market while I was on leave? Thanks. Barbara Richmond Barbara, I deal with lots of Kawai uprights. They seem to develop squeaky damper lever springs, spoon-felt interface, and pedals after awhile? I've begun using teflon powder on all contact points. A hobby brush works well to get it in the groove (is this also called a grub??) and on the springs, and I've taken to using the tapered end of a felt mute to get between the spoon and the end of the lever so I can apply it to the felt. The other day I had a "click" when the sustain was depressed that it took me awhile to figure out. Turns out, the action bracket wasn't wedged tightly enough into the nose-bolt, and was moving when the damper assembly was hoisted by the pedal. Ya never know....
