Heat it up first real good with map gas.

I had a similar issue and i ended up cutting the nut to take it out. if you are going to do that, BE VERY CAREFUL of the crank as you can easily cut it too

i gave it a go today...heated it up with map gas for about 5min 2 times and nothing...i dint think cutting would be an option but i thought about it as i was getting frustrated and was thinking about taking the torch to it and melting it ... how did you get the remaining part of the bolt out...did you drill it out was the shaft usable after.... i will try to look for stronger impact gun for now... but i just might have to cut it

Goemon=you
Weirdo=E-shaft pulley bolt
Solution: Blow on a conch shell to call IMPACT!!!!
This is proof that a giant robot can solve any problem

Sorry, couldn't resist the pun humor. I love that N64 game. Drilling should never be necessary as you'll ruin the E-shaft by never being able to set the end play again (requires fully assembled & torqued front stack). Heat plus impact should do the trick. If in doubt, Aaron Cake probably has the answer.

Prop the breaker bar against the ground or the frame rail and bump the starter. Just keep clear!

Heat the nut with a torch until its cherry red, it will then burn off the locktite and come off with ease

Do not cut off!! Screw that impact gun ****. Heat it up real good and use a good breaker bar with a pipe on it. If my 120lb *** was able to get off im sure you can. And when your done rebuilding that motor make sure you reflash ecu.
