So i took off the waterpump pulley with the belt and impact wrench method. Yey! However, the crank one wont budge! My impact gun is only 340lbs of torque tho...

 

You said the engine is on a stand correct? If so Jam a big screw driver into the flywheel. Get a breaker bar and maybe and long metal tube and it should come off. I didnt need the extension just a 2ft breaker bar........and that was with the bolt being rusted as well lol.


The other way it get the toyota tool or make you own, like this guy did

WHere are you located in cali ?? If youre in the bay area, I can loan you the tool I made. Pair it up with a nice, long 250ft/lb torque wrench and your done; No drama, just pure leverage ftw

(btw, Remember, you have to be able to retorque it to spec too. Youre not going to use an impact gun for that too, I hope.)

 

Updates! I got the bolt off! This is how I did it, follow these easy steps and you'll get your bolt off too!

1. Call your friend that works at Lexus.
2. Bribe him with food.

That's pretty much it! Two specialty tools later, the bolt is off! Then you're going to need a steering wheel puller or pulley puller to get the crank pulley out.

 

One time I had to use a 1" impact to get a crank pulley off my old Honda. Yea, that's right a ONE INCH impact gun! That's a lot of torque.
