Does the T-5 pilot bearing need to come out for an AOD to go in?

I had one that was stuck really bad once. I tried the slide hammer method but there wasnt enough to hook to on the inside of the bearing. Someone recommended the grease trick but as stuck as this thing was, I didnt think it would work. I ended up taking the slide hammer and pulling out the caged roller bearing part. That left me with a hole that was about .930 in diameter. My neighbor who is a machinist found a fine thread tap that called for a hole about that size. We cut threads in it, then threaded a long bolt all the way through until it touched the back of the crank. He then cranked on the bolt with a huge wrench while I held the main bolt on the front of the crank.

Later that day he looked up what the mechanical advantage of that thread pitch was. It was like 14 to 1. He estimated he used 100 ft pounds of torque to get it to break loose which I figure was about right considering how hard I had to hang on to the main bolt. That thing was freakin stuck.
