This is not as difficult as you may think. AT least we hope not.
The first thing is that you have to remove the electric clutch.
In many cases the clutch will just pull off.
In other cases you will have to use a puller.
Once you get the clutch off, usually you can just reach up and screw the bolt out with your fingers. If it is broken of inside the crankshaft far enough that you cannot reach it with your fingers, you may be able to take a screwdriver and reach up into the crankshaft and jope that there is a little sonething that the screwdriver can catch on to try to turn it out.
Fo not, then you will have to drill a hole (Smaller then the diameter of the bolt) and use an easy-out to remove the bolt.
If that doesn't work, then you will have to derill the bolt out and rethread the crank.
IF it gets that far, I would suggest that you have a mechanic remove it for you. In fact, I might suggest you do that in the firts place so you don't risk damaging something. It should only cost abotu $20- $30 to have it removed.
