I probably should have caught the worn out Wear Button earlier, BUT....
Now both the Button and Levers are gone! The disassembly went downhill from this point - I could only get one of the Set Screws out.  I finally gave up and.........

...ground the PTO off the crankshaft.
Now, all it will take is money...

That’s gonna leave a mark!!
Lesson learned: Rotary Grinder’s can produce a high-intensity stream of sparks that burn holes in clothes and skin!
