I would bet not having a variation holding tool and improvising with something to hold while wrenching nut in wrong direction. cluster all the way

When i tryied to unscrew it, crankshaft broke with nut at end. That fan wheel was broken in the procces, i have new one but crankshaft i dont. I will learn the hard way, no biggie.
