Bill, not certain I am following your thought. Are you indicating that my seals became very hot as a result of the malfunction? - please elaborate.
If your seals became cocked and jammed against the housing walls, the friction might get them very hot. Perhaps red hot. If they got very hot then it is possible that the hardness was reduced by this heat cycle.
My point is that unless you do a hardness test on a seal (or a portion of a seal) that you are certain never became overheated, you can't be sure if the lack of hardness was the cause, or the result, of the engine failure.
If they did I presume you are saying that they might have had their hardness reduced by the extreme heat? Just the failed rotor seals or both?
If the undamaged seals in the other (undamaged) rotor are soft, you have found the cause of the failure. If they are all hard on the undamaged rotor, you still are not 100% sure if one or more of the seals on the failed rotor were soft, but it is less likely.
