yes, the flywheel holes are NOT blind holes, if you don't locktite, or thread seal them, they can leak oil onto the clutch.
That's good info about the super king cobra, i like that idea.
The puller sucks, in my opinions. what works best is to take a very soft clay, or wet paper towels, and shove them through the pilot bearing hole into the end of the crank. (it's a dead end) next take something to seal up the inside of the socket. take a perfect sized socket and stick it through the pilot bearing hole, and an extension on the end of the socket, and use pressure to pop the pilot bearing out. I suggest a soft moldable clay, because it doesn't squeeze out of the cracks as easy. Just hammer on the end of the socket or extension until the old pilot bearing pops out.
You can white lithium grease the new one to get it in. I use the old pilot bearing, place it over the top of the new one, and use a very small section of 2x4 wood over it to hammer it evenly and easily into the hole.
good luck with the rear main. don't use a screwdriver if you can help it to pull the old seal out. If you groove the crank, even slightly, it'll leak. In that case, you have to sleave it. you can drill two holes into the old rear main, thread two screws into the holes, and pull the old rear main out. To keep the drill from sliding on the old rear main, use a punch to punch a good starting dent in the rear main for the drill.
