I have successfully removed the crankshaft bolt by the following method:
1) I bought a piece of "c" channel from home depot and drilled three holes the same pattern as the ones that hold the pulley on. I cut a slot for the crank bolt. This is 36 inches long and heavy duty. I propped it against the front frame rail. Tightened the bolts very tight to avoid damage.
2) I then put a 22MM 6 sided socket (actually 7/8") on the bolt, a short extension, and a 3/4 inch breaker bar (round). I made an extender with a piece of 3/4 black iron pipe. I jacked the car up taller and put in on a heavy duty jack stand. The piece of pipe I could fit under the car was 21". I braced myself on the steering knuckle and pulled very hard and it finally came loose.
Air impact wrench, and starter method did not work. Good ideas, but alas a BFW was the solution.
If anyone is interested, I'll post pics of the bar.
