Hi Phil,<br>
Use a sharp pencil and make a line along the belly rail, at the top
of the damper up stop rail, Loosen the up stop rails screws
and raise the rail as far as you can just snug the screws to hold
the rail up.<br><br>
This will give you plenty of room to tighten the tray screws.<br><br>
Reset the rail to your pencil lines. check the rail/up stop
regulation. there should be 2mm clearance from the bottom of the
tray to the felt on the top of the dags, Adjust the pedal rod to make
sure this is correct, and 1mm of lost motion to the underlever
capstans, check to make sure all dampers lift evenly.<br><br>
Depress several sample keys so they just rest on the front rail
punching's , You should be able to lift the damper head 2mm up
wards. This is an important adjustment.<br>
If too much travel, the action will feel bumpy, if too little it
can feel spongy.<br><br>
A good flash light makes the job a bit easier.<br><br>
Hope this helps<br><br>
Regards Roger<br><br>

<blockquote type=cite class=cite cite="">Came across a Yamaha C7 aluminum
damper tray that was making noise. It was loose and moving
forward and backward due to a loose screw on the left flange.
Problem is I can't tighten the flange screw since the damper tray hinge
is covering it and I can't lift the damper tray high enought to get at
them.. How can one tighten the hinge screws without removing all
the damper wires, back action etc. Can anyone help?<br><br>
