Ditto what everyone else has said. Also, in the end you will see the hammer tails clicking or hanging up on the wippen flange screws. I was called in on one at that point. The brackets were cracking from the stress of trying to expand while being constrained by the keyframe. Had a devil of a time getting the stack off the keyframe. The basic diagnostic criterion is spread. Get the spread spec from Young Chang; I had it years ago but no longer. If the action is out of regulation, especially letoff, and the spread is too big, you¹ve got a bracket problem. Regards, Ken Z.
