I know this is dusting off an old thread, but do you remember it seeming odd that there were only 6 bolts in the gear retaining ring when there are nine holes? Do the three that hold on the end cap go all the way through to the support?
I tore mine down and just don't remember removing nine bolts from the brake assembly and only have 6 of the black allen head bolts and 3 stainless allend head bolts that are longer.
