Is this burned up friction still flat?
There should be a big fat steel plate about .25 inch thick as the first plate in ; was it there? There is plenty of evidence that the steels were only driving a small percentage of the friction material.; this means something was amiss; they were NOT being properly sandwiched.
My first thought, not properly indexed, is not evidenced in these pics.

In the pic below; what is that serrated business just outside the spring clamp? I don't remember any of my hi-drums having that. Is that what cut your planetary?
