  • 1.  KAWAI Studio Pedal Adjustment

    Posted 06-08-2017 20:55
    I've tuned a 1970s Kawai studio for years, and I've always had trouble getting the funky sustain pedal adjustment to stay put. This is the one where the sustain (right) pedal linkage acts with the middle (bass sustain) pedal linkage. I get it set correctly, and it falls out of adjustment. I've used Loctite on the wing nut, etc. to no avail. Has anyone any tips on this setting?

    Phillip,

     

    Your Loctite method should work!  I have used just a little wood glue on the threads at the top of the wing nut to keep it from spinning, since it's easily reversed.

     

    If you've stopped the wing nuts from spinning then there may just be something else wrong – take the pop bolts out and see if the leather underneath is worn out, check that the trap levers and pedal hinges are tight on the piano bottom, just look all over for problems.

     

    Pedal rod ends can also be worn out – you can get new rubber grommets from Kawai, or install bushing cloth in the damper lift rods instead.

    I love that new material, bushing cloth, to eliminate for all time clicks from the pedal rod 😎

    It may also be that the damper rod is broken or warped. Or the rod bracket is loose or broken. Or the "rod dogs" (hooks) are broken, bent, loose or missing. 

    Of of course you may not be able to tell without removing the rod, which can be a big hassle. But if that is the problem, the only way to fix it is to remove the rod and repair / replace the part that's not functioning properly. 

    Hope this helps,
