Thanks,

Really disappointed about this.
Didn't try to piss around with a screwdriver or anything. Made a tool that worked and should have been plenty strong enough. It just wouldn't budge.

Took long enough to figure it all out too which is salt in the wound. Have done hundreds of repairs to all kinds of cars and bikes. To this day, this stands as one of the biggest pains I have ever gone through. No room to work, everything in the way. Damn it's brutal.

I guess the good news is that I am replacing the waterpump so it doesn't really matter what happens to this one. I had soaked it in WD40 too which didn't help. The only option now is to try and get my propane torch on that nut to heat it up and expand it a bit. First I need to now fabricate another tool and I am going to smash off what's left of that pulley to give myself more room between the fan blades and the waterpump itself.

Bummer
