    Default 4AGE 20V Blacktop - Crank bolt stuck hard

    Car - AE71 Pano

    motor / part in question - 4AGE 20V Blacktop

    problem - Crank bolt stuck hard

    occurs/started when (if applicable)- Timing Belt Change

    personal situation (if applicable)- Wild

    Doing timing belt change on 20V Blacktop motor (motor out of car)
    I firstly used a tool I made to hold the crank pulley in place so I could get the bolt undone.
    Used it before with no issues on multiple engines.
    It bent and cracked, so I bought a proper pulley holder.
    Been waiting for delivery, hanging out to get this tool and get job done.
    It arrived yesterday, so had a little play around with it to familiarize myself with it.
    So just now I got to use it and this happened.

    This Crank bolt is on with some serious force.
    I think someone has used locktite and hammered the thing up with a rattle gun.
    My next thought is to lock the flywheel in place with a ring gear locking tool.
    My problem is, if I lock the ring gear I'm transfering all pressure on the rear of the crank.
    Is there any change I can snap the crank wilst hanging of a breaker bar?
    I'm serious, this bolt is farken tight. I know 4AG use a forged steel crank form factory, so this is a plus, but is it possible?
