To get the crankshaft bolt loose on my Toyota pickup: Get two sturdy pieces of angle iron long enough to fit from your crankshaft bolt to the ground at a 45 degree angle (about 30" on my Toyota 4wd 3.0 V6 pickup). I used a piece of old bed frame cut with my skill saw and a $2 metal cutoff blade. Newer bed frame might be too weak. You can probably obtain some angle iron at your local home improvment store. Bolt the angle iron together at one end to form a tight angled V (you will have to drill a large hole and use a large strong bolt/nut). remove the four bolts securing the air conditioner pulley to the front of the harmonic damper. Use the air conditioner pulley holes as a pattern to make/drill two holes, one on each piece of the angle iron at the opposite end from where you bolted them together. Make sure you leave the large center round hole completely unobstructed by the angle iron when you mark the holes (otherwise the angle iron will interfere with the pulley locating flanges on the front of the damper). The holes should be about 3/16" from the inner edge of the angle iron. Take this assembly and bolt the two holes to the front of the damper pulley using the air conditioner pulley mounting bolts. Snug them up a little. It should fit flush against the damper (I had to remove the air conditioner idler pulley with a 14mm socket) and the bolted-together end should rest on the ground (preferably concrete) about 2 feet to the left of the damper (passenger side). Get a craftsman 1/2" drive 6 point 19mm socket, 1/2" short ext and 1/2" breaker bar (thats what I used) and a two foot piece of pipe over the breaker bar for leverage. Spray behind bolt flange with WD-40. Wait two weeks (optional). Spray again. Attach breaker/short ext./socket/pipe assembly to bolt squarely. Push upwards from driver side. Bolt came loose easily for me. Safer than the starter trick. Easier than the ring gear trick. Cheaper than buying/renting expensive air tools. Hope that helps.
