Im worried that I have bent the crankshaft sprocket end of my engine while trying to remove the crank nut with a breaker bar and the crankshaft holding tool (which I managed to bend considerably)



The new harmonic balancer wobbles a bit, as does the shaft it sits on. I tightened the nut as much as I could with a 1/2” ratchet wrench to ensure I didn’t cross the threads when I gave it a couple ugga duggas with the 600ft lbs impact.



This part of the crankshaft
Also because of this, my brand new timing belt is riding towards the block and occasionally squeaking.

Is it possible to bend this? I understand the crank is forged and I don’t honestly think a 5’ 7” guy who doesn't go to the gym can bend a 1” diameter forged rod with a o’riellys 30” breaker bar.

Do I just need to tighten it more? Imma be for real and say the crank nut randomly started moving a lot more after tightening it and I don’t know if thats the paint coming off the balancer or me beginning to strip the threads or the wd40 i used to make sure the harmonic balancer didn’t bind making its way from the inside edge of the balancer to the threads. It’s definitely on there tight since I cant loosen it with the breaker bar

 

I don't really think you can bend the crank on any car.

 

I’ve definitely heard of it before, especially with the B5234T3 having a forged crank. It’s more ductile (bendable) than cast but also less brittle (breakable). Given the brand new timing belt is definitely riding off track, SOMETHING must be bent and that means it must be the crank or the sprocket/hub. And I wanna know if someone can help me diagnose this before I drop 80$ on a new sprocket + hours of work to get to it just to find out the crank neck is bent.

 

I think your video shows that it is bent. I would accept that as proof anyway. I was thinking you'd have to be in a crash or something to do that, but maybe not. You could try to bend that again, but of course getting it "just right" in the car is going to be pretty hard.
