[pianotech] muffler rail

>From the looks of the picture it seems that the spring has been hooked to
the part that is supposed to be hooked to the metal rod that connects it to
the pedal. When the muffler is in the correct position, there should be a
small hole in a part that is on top of the rail for the spring to attach to.

 

To reattach the rail do the following. Look for a metal rod lying against
the side of the piano by the muffler rail. It should have an upside down J
at the end of it. Take the pivot pin that locates the end of the rail out of
its hole and let the rail drop low enough for the upside down J end to slip
into the part with the red felt. Lift the pivot pin up and into the hole in
the side of the piano. This will keep the muffler rail down. Now find the
small hole that the end of the spring came out off and reattach it to pull
the rail up. You will most likely find that the spring works fine, but you
also may have stretched it so that it needs to be replaced. 

 

Hope that this is not to confusing but helps. The main thing is that you
have attached the spring to the part that should be attached to the pedal
linkage.

Hi Joe,
I hope this pic is big enough, unsure how to enlarge it for now.  I think
it's the spring on the left in the pic. By examining it, it looks funky in
the middle.  Plus it will not hold the hook with the red felt in the correct
positinon.  When I turn it to the correct position, the bracket just flips
back so that the  hook is pointing in the wrong direction.  Would a new
spring with less stretch in it hold it tighter and in place?  When I took
out the spring, it felt flimsy or whimpy in the middle, like a weak slinky.
I don't recall seeing a guid pin on the right but do know exactly what you
mean.  The problem I ran into was as I mention the hook with the felt in it
that the rod slpis into wil lnot stay in the correct position leading me t o
think that the spring is bad. I Hope the pic. is big enough.  thanks  
Marshall
