[CAUT] Pedal noise on DC3

[Jeannie Grassi]

Hi Dennis,

I had a similar problem just a few weeks ago.  Dave Durben recommended that
I look at the pedal solenoid.  If there was dark dust around the felt
collar, it indicated that it should be cleaned, and lubricated, in addition
to calibrating it.  I took some 400 or 600 grit sandpaper to it and got it
all shiny again.  Squeak was gone and it moved much more feely.  Problem
solved.  

 

If you have problems, talk to Yamaha and they will help you with it.

Hello-

Has anyone had an intermittent noise/squeak originate from the electronic
movement on the sustain pedal of a DC3 Yamaha? We have a mysterious and
ongoing noise complaint from one such pedal that I have never personally
been able to confirm for about a year, but yet the complaints continue.  ???
I have eliminated everything from the normal acoustic operation, so what
next?  I was about to suggest it could the shoes, but didn't dare.  I do
seem to feel some resistance in that cylinder but can't confirm if that's
the cause and wouldn't know what to do if it was. ...   This unit dates from
maybe 6-7 years ago.  It's not the latest model with one simple adjustment
screw in the center under the cover plate.

thanks,

Dennis Johnson
