[ICOM] How to remove the tuning knob on ProIII?

[John Pelham]

Hello all,

How does the tuning knob on a 756ProIII come off?  Does it just pull 
straight off, or does the rubber ring slide off to reveal setscrews?

I want to remove it because the tension, or drag, is still too high even 
with the brake adjustment screw turned as loose as it will go.  According to 
the service manual there's a "brake pad" (felt washer?) in there.  Maybe I 
can modify it or remove it to make the knob spin more freely.
