Your opinion ? (see attached a picture of the contact)

Hi Carol,OK, we did what you recommand, we found the notice on the back of the black cover : "loosen lock nut A then rotate adjusting nut B until the upper line G on the rod is the same height as edge line F. Tighten nut A to lock it. When pedal adjustment is correct, line E never goes higher than edge line F when the pedal is fully depressed." very clear : we did it but previous position was ok at 1 millimeter, not so big change, still hot, maybe slightly less. Note : E is very far from level F when pedal is fully depressed. What is better that to be at exact level F : level G to be slightly upper level F or slightly down of level G ? Or maybe is another problem. Thanks so much for your help.Julien

Inside the black metal cover over the pedal solenoids (on some models) is a
diagram of how to adjust the pedal solenoid. It is very simple. However,
for what a Mark IV costs, I would have both a piano technician and an
electronic tech present to do the adjustments. I would contact your Yamaha
Dealer for a recommendation.

The angle should not make a difference. I
have been trying to figure out a way to ask you about "lost motion" of the pedal
stroke. When you press the damper pedal (the one on the Right) how far
does the rod move before the dampers lift? There should be a minimal
amount of motion. Since the solenoid appears to be in the proper place,
perhaps the nut at the top of the brass rod needs to be adjusted so that the
dampers move after the pedal has been pressed down only 1/8 inch.
Also, the capstan screw attached to the underside
of the piano that connects to the square piece on the pedal rod can be unscrewed
and adjusted downward to limit the travel of the pedal. It should be set
to stop the pedal motion once the dampers have cleared the strings.
This is where a piano technician comes in handy!
Perhaps the ideal situation would be to "Skype" a piano tech with a web cam to
check this adjustment. This same video tech support could also guide you
through the electronic adjustment of the pedal solenoid.
The folks who sold you this piano should have
access to a proper technician.
