>>I also have heard that on newer Steinways, they use a neoprene tube inside the box, instead of a wrapping of bushing cloth to muffle the clinch plate. Sometimes the neoprene introduces a lot of friction. If I found that, I'd just take it out and use bushing cloth again. With new cloth, it takes a second tightening after the pedal has been used a bit, or the cloth getting pressed down lets the pedal get too loose. <<
When using cloth in the STeinway pedal clamps, there should be no need to retighten if the screw is screwed down far enough at first. The design is for the clamps to form the proper sized hole when they are fully tight. Those plates need to be tightened until they are metal on metal, forming the hole for the busing and rod that is sized for them. I like .055" cloth, and I do graphite it. They are really firm at first, but after being too tight for a sonata or two, they should go on to work for years without more attention. The Teflon tubes that have replaced the cloth work well, and with clean rods, I haven't had any problems from them.
New rods are a normal part replacement by the time I have the plates loose, unless the old one is really in nice shape. If there is no way to get a new rod in the time allowed, it helps to turn the rod 180 degrees, providing a new, un-damaged bearing surface to the direction of load.
