It affects all 13xx series ones that has aluminum top with
countersunk philips screws. I had to fix my 1355 (esdi 150mb) also
and other one I could not recall.

Good idea to check that brake too and see that felt is still alive
and in right place. And house dusting in is in order also. They do
have black plastic fan ring snapped onto motor housing. It has also
alignment arrow heads.

Suppose micropolis used silcone instead of that dumb natural black
rubber pads we would not have to open them up by now!

You can undo those 2 captive slotted scerw heads and hinge logic
board up. Neato!
