Removing Sticking Damper Underlevers on Asian Grands

[Dean May]

Hi Rick

 

If you hold your tongue just right you should be able to unscrew the flange
and pull the underlever out to properly repin it. I would suggest rolling
the dice first. If it turns up 7 your luck is running high and you shouldn't
have any problems. Seriously, it can be done, it is just rather tedious. 

 

But perhaps the problem is not the center pin. I've noticed on many Korean
pianos that the problem is not enough offset in the lift wire. Use your wire
bending pliers and put a little more kink in both bends, see what happens. 

 

Blessings,

 

Dean

OK, I've now been stumped twice on this particular problem by two fairly new
Korean grand pianos.  I'm convinced the problem is the underlever, but
cannot get the XW#@ things out to rebush and repin them.  The last time, I
was able to unscrew the offender and bring it forward (but not all the way
out of the damper underlever system) enough to douse it with lubricant.  And
it worked wonderfully for about two weeks - but just got the email this
morning that it is sticking again.  Help please on how best to go about
getting these little devils all the way out of the piano to correctly deal
with them.  Please don't tell me that I'm going to have to remove the entire
damper system...
