The rail the hammers are screwed to went too high, and moved left about 1 cm. The damper rail went too high, too.By taking the action out and applying pliers, I got the hammer rail to move right so the jacks and damper spoons lined up vertically with the hammers: Without breaking any.The damper rail is much too high, and squeezing it down on one end makes the other end go up. The hammers hit the mount rail if damper rail is too high, and the hammer spoons don't push the damper levers.
