How to remove crankshaft pulley bolt

If you go to autozone there should be a wrench called a chain wrench that will help ALOT keeping that pulley stiff so it won't move when you go to unbolt the pulley just put that over the pulley and in the middle should be a bolt use the right size bolt and a breaker bar (long metal pole over the back of your ratchet) and right tighty lefty Lucy hope I came to some kind of help! :)

I am having the worst time ever! My lexus rx300 2000 3.0 bolt is truly the worst. Ive heated the bolt but not too cherry point just heated with plumbers torch. Then the starter bump method and still nothing. Tried braker bar extention 5.0 ft and nothing. Heres the bad part, i bought a 30 gal 150psi compressor and a new 1000 ft lbs impact 3/8 line through out and broke two 22mm sockets so i got a impact socket set still nothing. Went through 2 cans of PB blaster a can of 40 year garentee and nothing hapened. Made my own tool that bolts onto the pulley to keep the pulley locked tight in the sgape of a long arm V outvof 1/4 x 2.0 steel. This is the worst engineering i have ever come acrossed and why does it need factory tighten 180 to 210 ft. Lbs. When the pulley turns opposite its self tightens. This could change my whole out look on Lexus and Honda and Toyota. I heard using a torque multiplyer if you can find one under 300.0 and fits your car. What can i do to bust this dam bolt loose before it strips out. Please help its been two weeks now.

I used a tow strap and hooked it to the front motor mount, ran it around the pulley, and a little slack to tighten the belt behind the fan belts but overlapping it works all alone. I used a wrench and the long bolt from the engine mount bracket with some sockets for spacers to pull the pulley. I put a vice grip light on the wrench at the opposite side of the pulley and used the HB bolt to pull the pulley.

I could only put one pic and the first of the strap got nixed. Here is that pic I have a pic of the bolt out and the pulley off, but do this and take one yourself. Seriously this bolt seemed to have a locktite glue on it to boot. It was impossible but this did it. The pulley eased right out too.

I bought a Harbor Freight 20V 1/2” high torque impact gun and a weighted deep socket and to my shock and surprise it took the crankshaft bolt off instantly. It had never been off. Then I used it on 2 Hondas and the same result. I used to put a cheater bar on it and bump the starter. That works instantly too but isn’t the safest way to do it.
