fallboard vs. keytops

Does the action shift correctly? One of the things I have seen working for a
piano store is that the movers sometimes do not put the leg/lyre bolts in
the correct place. Some pianos have shorter bolts for the front legs. If the
long bolts are put in the front, it will cause the action to be lifted on
that end. Usually the complaint is the piano will not play correctly in the
treble, but someone may have lowered the hammer line not realizing that the
end of the keyframe was in the air; resting on the leg bolt and not the
keybed. This could cause the treble keys to be high enough to be depressed
by the fallboard. The quick check for this is to try to shift the action. It
will not shift in this condition. (You will also have to back out the
offending bolt to get the action out.) The solution to this problem is to
take out the offending bolt and remove one bolt at a time from each of the
other leg and lyre positions and compare the length. (If you take a bolt
out, check it and replace if not shorter before you take out the next bolt
you will not have to worry about the piano legs or lyre falling off.)

 

Course it could be that the pin is in the wrong place or installed
upside-down.

 

Just a couple of obvious (and not so obvious) ideas on things to check.
