Yes I did notice that. Perhaps they incorrectly listed the ft-lbs measurement first and based the other 2 on it so they ended up incorrect as well.

Re: Crankshaft tightening 181 ft-lbs + 90 degrees!
So you need the circa 2001 version of the manual and the latest revision and compare them on every project? Perfect!
Also, I followed a DIY on this forum and I did in fact do 14ft lbs + 90 degrees. I remember that while this is "tight" I did not feel as though I was at risk of sheering.
Here is the DIY I followed https://www.civicforums.com/forums/1...t-diy-2-a.html and all in all I had very few issues. Careful not to break the dust cover for the timing belt. It's either shockingly fragile, or I'm just too rough.

Re: Crankshaft tightening 181 ft-lbs + 90 degrees!
I am seeing a lot of answers of 181' pounds with 90 degree turn all the way to 14' pounds.
The answer below is for a '09 Honda Civic LX
If using same bolt (used bolt); 51' pounds
If using new bolt; Tighten to 130' pounds, loosen the bolt and then tighten to 51' pounds
When using the same (used) bolt, only 51' pounds is required since the initial installation of the bolt was already torqued to 130' pounds which allows the bolt to expand, was loosened and then tightened to 51' pounds. If you torque the used bolt any more than 51' pounds, you take the chance of snapping the head of the bolt off which becomes an even bigger issue than the one you most likely had initially.
When using the new bolt, the initial torque of 130' pounds is required since you need to expand the bolt. Loosening and then tightening to '51 pounds then allows that already expanded new bolt to set securely and snug into the threads of the crankshaft pulley.
Good luck all with your automotive repair endeavors!

thanks for trying to add info, but if misguided, it is not good.
also, don't revive old threads if possible.

Hence why I mentioned the 09 Honda Civix LX. Yes, this torque specification is for R18A4 engine.
Torque specification advices per the engine series mentioned is correct.
Reviving the crankshaft bolt is okay if done correctly. I know personally many Honda service technicians, some with 40+ years of experience, advising of this very same information per the R18A4 engine.

I'm good on looking at these car forums. Way too much information being found here. I'll stick with the experts and not just a bunch of people guessing at what is or is not correct.
Good luck with the guessing game!

What are we guessing at? You're posts don't make any sense. You posted info about the 8th gen Civic into a 9 year old 7th gen Civic thread....
