Depends on how much you go over, but considering this is a serious hypothetical, if you haven't already over-torqued it, just make sure you don't. If you already did, tell us by how much and if anything is noticeably wrong and we can help you remedy it.

Anyway, to answer your question, significant torque over spec will probably screw up the threads on either the nut or shaft, both very bad. Insignificant torque (within spec), well, it's within spec. Moderately out of spec, it may work fine for a while, but could cause catastrophic failure after it's had time to ponder when would be the worst conceivable time to fail, and fail hard.

As always, do it once, right.

well we over torqued it that if we try to tighten it, theres no resistance, same thing if loosening. going either ways goes no where. when i look off the flywheel stopper and turned the flywheel and front portion of the engine, it seems fine. i dont know what else to say ??? hopes its not bad

How do you know you overtorqued it?
Were you cranking on it with a torque wrench?

So... you tightened down the flywheel, and now the flywheel nut just freespins on the shaft? You didn't happen to cross-thread the nut did you?

If the threads on the shaft are fucked, the engine will have to come apart to install another shaft.

I was there, I turned the crank pulley, it turned the flywheel, and we turned the flywheel and we heard the rotor compressing. Also the thread looked messed up before we put in the flywheel nut.

New thread title: Tweedle dee and Tweedle dum's engine build

So, you put the nut on the fucked up shaft and just cranked on it? Jesus, you should have been able to spin it on by hand, then tighten it to spec.

if i had to guess i would say that the nut is a much softer metal then the e shaft, so you might be able to get a new nut. lol good luck

His threads after this he was looking for an eshaft, and the last thread was selling his PowerFC. I'm guessing he cut his losses.

I was thinking the same thing.... Hard for me to imagine the level of stupid that would be required to strip a flywheel nut
