use whatever tools you have available to destroy the rubber. maybe a 1/4 inch drill bit making a few dozen holes in it.

It is a LOT easier to break the cast iron stub out and then just peel/roll the gasket out.

for you, me and our friend from SC, i agree.
but for an inexperienced homeowner i'm afraid they might crack the hub.
better safe than sorry.. destroy the rubber.

I would say a sawzall with a metal blade, saw the inside parallel to the pipe and collapse it on itself, but that old cast iron is like cutting concrete in my experience....could you use a torch to burn that rubber out or would the heat crack the hub?

the heat wouldn't hurt the hub at all.
yeah, sawzalling the pipe would do it bur destroying the rubber should be alot less work.

We took out the cast iron stack in our 1917 NY house and a carbide-tooth sawzall blade barely scratched the pipe. Angle grinder with metal cutoff wheel did some damage, but in the end the most effective tool was the sledgehammer, of course we weren't trying to save any fittings either....
