Now that I have rebuilt the pto clutch and put things back together, I'm quite sure that the proper way to attach the brake disc is: bolt, disc, lever, washer, spring, washer, nut. The first washer is needed to keep the spring from working it's way through the lever and into the disc. By assembling it this way, the spring on the back side of the lever allows just a little flexible movement to let the brake disc meet the face of the clutch squarely.
I had a little trouble removing the clutch assembly - the set screws had been rounded over by a PO and I had to use a cobalt drill to drill them out but with a little patience they all drilled out and the threads cleaned up nicely. My next project is to make a replacement brake pad replacement for the old shoe and see how well that works out.
