Hi All, I thought I could solve any damper pedal mechanism squeak, and up until recently, I've had pretty good luck. Then I met a recent model Hallet-Davis (Dongbei built, I believe) upright. I lubricated and tightened everything I could think of. Here's the list of things I tightened and lubed: Lubed damper flange centers (protek CLP) damper springs (teflon powder) damper lever felt with teflon(two weeks prior) and protek last night lift rod with protek all rod tips and linkage w/ special blend tightened all screws on the various rails pedal rod hinge screws all pedal brackets and fixture screws all damper flange screws all available case screws In addition, I inserted buckskin pieces in places where case parts were rubbing and replaced the rubber pieces where the pedal rod inserts into the lift rod with buckskin pieces Noise still there…..argh! It sounds to me like it's the damper lever felt/lift rod interface. It doesn't happen when the pedal is first being used, say for 20-30 presses of the pedal. Then gradually, the creak comes back. I don't know what else to do. Did I miss anything? Any ideas?
