Hey guys, new member here so please be patient with me!

Im replacing my timing belt/water pump on my 90 Lexus LS400, im currently stuck where I have to remove the crankshaft pulley bolt. Any suggestions how this can be done without the crankshaft pulley moving freely?

The tutorial I seen here posted, they listed to wedge a impact wrench to ground and crank the motor, Im looking for an alternative suggestion on how to remove the bolt instead of going this route

Any help is appreciated and Thanks in advance!

I'll be interested in the expert members answers to this question. I was unable to remove it, and had the car towed to an indie 2 years ago. He got it off primarily by applying extreme heat to the bolt with a torch, after trying all his tools, including the impact idea. The removed bolt looked wasted, and of course, he had to order a new bolt (took 2 weeks for some reason). But as he said "I was afraid I might snap off the bolt, and you don't want to snap it off in the pulley." Cost me a bundle, but his work was excellent. Best of luck.

Drill out the center of the firing end of a spark plug and install, swedge, a steel rod long enough to hold the piston at BDC with the modified spark plug installed. A rubber furniture leg cup on the end of the rod will prevent scratching the piston top.

there is a Toyota/Lexus specialty tool available on ebay to remove the bolt. Works like a charm. cost about $70. it works the same way the harmonic balancer does by attaching screws into the pulley yo stop it from moving. It will not damage the pulley or the bolt.

I called a dealer and a tech told me I can stick a screwdriver in the gear of the flywheel and use an impact gun, has anyone tried this before?

We use a crankshaft pulley remover. Really! That's what it's called. I looks just like a steering wheel puller. LOL!!!!

the only ones I know of that are a problem are the Mazda, Ford 2.3 liters. They aren't keyed to the crankshaft so when you loosen the bolts it can slide out of position. Makes them the biggest pain in the a$$ I know of. The Lexus should be easy though.

First off, you have to prevent the crankshaft from turning. Vise grips, screwdriver, or something to stop the rotation. Then I use a 3/4 drive and a breaker bar for leverage. That's it. If you have a pipe to slide over the drive handle to make it longer so you can get enouph power behind it is usually all it takes. I think a 3 to 4 foot breaker, or extension and the bolt backs out like butter. That's it bro.
