To get it off? I just recently did my timing belt.

Crankshaft pulley bolt, All of these methods did not work for the Gsr bolt. I broke 1 greakneck socket and a craftsmen. Although i hear the ls crankshaft pulley bolt comes off alot easier, 1/2 impact gun will do it.

Non of these worked but you might try for the gsr bolt:
1. 8' breaker bar with 4 inch pipe extention.
2. 1/2 impact gun 230ftlbs torque
3. using the starter to bleep the bolt loose.
4. bolt drenched in Pb blaster, Wd40, liquid wrench.

What eventually worked was i called my buddy who worked at honda/acura dealership and he drove over with an oen pulley holder, impact socket (19mm), extension to a 1/2 breaker bar w/ a shop jack handle (3/4 of your arms spread out). Even that much torque it took some power to get it to come off.

a 3/4 impact wrench will definantly work 500ft lbs of torque shocking at 900ft lbs.

It's one badass bolt if you didn't know, i'm just warning you because i spent 8 hours trying everything to get it off and i wish i knew what it took. Would've saved some time.

 

I got all the belts off the pulley and there is something definitely wrong with it. It is easily wobbled by hand like if someone had assembled it without the spacing washers. All the washers look intact, so it may be a problem behind the pulley.

Once I get it off tomorrow, I'll see what the problem is. Thanks for the tips, FooD.

 

when using the start to break the bolt loose, becareful because incorrect rotation of the engine can cause a lot of damage.

 

Yeah, that would be my last resort to getting the bolt off.

 

yes, It's standard threading as well.

 

So I got the pulley off tonight. It was much easier than I though mainly because I suspect that the washer was seated incorrectly when the bolt was torqued. This caused a space between the bolt and the washer that was slowly being broken free over time with the vibrations and rotations of the pulley and crankshaft.

Here are some pictures of what I found:



The key is there and intact.



Check out the wear on the splines. Is that normal?



Here is the bolt and potentially the source of the problem. It is all rusted and the threads are broken. I plan on replacing it.



Here is a view of the worn splines on the crankshaft. Is this normal?



Here is the damage of the lower timing belt cover due to the wobbling of the pulley.



Hopefully the new pulley comes on Friday and I can get a hold of a new crank bolt/washer so it will be functional soon.

 

It shouldn't be worn like that...but I don't think it's too bad. I would bet that it was caused by the wobbling of the pulley. I'd definitely replace that crank pulley bolt, and check the portion of the crank that the bolt threads into for stripping.

 

Definitely. I agree with that. I am just trying to find some sort of way to explain why this happened. Everything else checks out, so this is really the only thing I can think of. The bolt came off surprisingly easy with just a 2 ft breaker bar, so it may have not been torqued correctly.

I plan on replacing the bolt/washer. The threads inside the crank look fine, just the ones on the bolt are bad due to rust and corrosion.

 

The wear on the splines do not look great. They could be better. If they are not toothed in there precisely and snug that will generate a disturbance that can begin to vibrate and knock at the crank shaft bolt holding the pulley on. Eventually the power of your motor is going to win that battle. And I know you have some ponies. Maybe now is the time to consider upgrading your pulley if you haven't done so already. It's already off, and I am predicting your crank power is going to cont. chewing a new asshole in your pulley and quite possibly cause damage to itself as well.
