You might try a bit of heat. The second link I sent you suggests this:
"The top plate is retained by a screw on each end; the film advance leverwind and, the film rewind knob.
The latter simply unscrews in the conventional manner. The advance lever cap is normally threaded (counter-clockwise to remove) but there seems to be an endemic problem in removing this component which I suspect is torqued up by Mr. Yashica's personal Sumo Wrestler. If it does not yield to reasonable untorque pressure don't keep increasing your muscle-power because you will surely shear the small diameter underside thread. Give that cap five seconds under a pencil-point butane blue flame to break the stiction and it will then screw off easily. The meter ASA knob stays with the top plate and needs not to be tampered with."
Thanks! I'll be sending Mr. Yashica's personal Sumo man a stiff letter.
