How "new" is the piano? Is this something that the dealer should take care of, or at least pay you to do, instead of having to eat the work?

Subject: [pianotech] P22 Sticky Keys


A couple of weeks ago I serviced a new Yamaha P22 at a school I tune for, the vocal teacher having complained of many sticky keys. And she was right. Probably a half dozen were not returning at all and the rest all had excess friction to varying degrees. There was tightness at the front rail bushings as well as the balance rail, so I eased every bushing and applied ProTec to all key pins. Also checked the action centers and found no excess friction there. Then I checked and double checked all keys with the sustain engaged and releasing the keys slowly. I wanted to be thorough since this school is an hour away. I get a call today that just two days after I worked on this piano, the keys were sticking again, just as bad as before! I can't hardly believe it but I'm going to take her word for it. Has Yamaha changed anything in their new pianos? Different bushing cloth our something? I am probably going to have to eat this next service call so I want to get it right. Am I missing something?
