Many years ago when I worked on the line, we would put a 24 inch pull handle on the bolt and rest it against the frame. Then we would use a remote starter switch to just "bump" the engine over. The starter would loosen the bolt and we'd take it the rest of the way out with a ratchet and socket. Be VERY careful to not get your fingers between the wrench and the frame or you could lose a finger or four.



The next best thing is to use a half inch impact wrench on it. The impact wrench will loosen it with minimal turning of the crank.
Just use an impact on it. If you dont have one most hardware stores will rent an electric one to you for $10 an hour.How do you remove the center bolt on harmonic balancer of a v8 318 mopar?
Put the belts back on and let them hold it still
All 3 of the previous answers will work. But there's another way that's less dangerous/expensive/work. Simply remove the torque Converter/Flywheel inspection plate, and jam the tip of a decent sized flat-bladed screwdriver or prybar in the teeth where the starter engages, so that the shaft is up against the drivers side of the transmission bellhousing. Now, when you turn the bolt, that will keep the crankshaft from turning.



Or, they actually make a special tool to do this, called a flywheel turning tool. Works great for holding it still too.

get a breaker bar and a long cheater pipe, lock it on the frame someplace and hit the starter. let the starter loosen the bolt.i did that several times.
