Default Crankshaft pulley bolt removal

Has anyone removed the crank/pulley bolt? I must have exerted about 200lbs of torque and hasn't budged. I assume its a right-hand thread?

It's off, but I had to use 5' level arms. I had to machine a steel plate into an adapter to bolt on the crank pulley. It is right-hand threads.
The book says to apply 300-400lbs-ft of torque to install...Wow. If you don't have a proper pulley holding tool, its hopeless to remove. I made a tool on my lathe.

Default Had same problem

When I had to remove the pulley a friend came over with his compressor and air gun. We cycled back and forth between his compressor and mine. Except for a few breaks to let the pressure recover, we pounded that bolt for ~20 minutes. I would have given up but he said keep going and it finally gave in. We were doing it with the engine still mounted so cannot think how we would have removed it otherwise.

From my experience, I would make a tool to hold the pulley, and not let the shock from an impact driver get down into the crankshaft. How did you hold the crankshaft?

Did not hold the crankshaft, just let it work against the compression. In the whole time we used the impact gun the pulley turned less than 1/8 turn. My friend is a long time car mechanic and he says this is how they always remove the bolt.

It's been a while since your post but I thought I'd add for anyone in the future, When I worked on my Verona a few years back I already had the engine out of the car before thinking about removing the Bolt. It seemed pretty hopeless. I broke down and bought the pulley holder. It didn't do much. The bolt is so tight that with the holder and a long breaker bar it wouldn't budge. Eventually I bought a large pneumatic impact wrench (7 or 800 pounds of torque) and it EVENTUALLY go it off.
