Okay, I wish I did not have to post this but I got stuck. This morning I found some time to change my front oil seal that has been leaking for a while. I had also bought a timing belt just to change that as well. I got everything off I could, drive belt, timing cover, ect. I could not Get the center bolt to come out of the crank pully. I tried everything I could. Is there any trick to this you guys know of, or if something has gone wrong. I'd appreciate all help, thanks guys.

Impact gun, heat shocking to release any bond with the thread locker if any, or use a breaker bar against the ground and bump start the engine <- yup seriously!

I made a 2.5' long breaker bar, with a flat end that bolts on using the four pulley bolts. I slip the harmonic balancer off over the main bolt, then bolt the tool on in it's place.

As far as I know, that's the safest way to loosen and tighten it.

Get a better impact or do the starter trick.

I had one stuck on a 1.5 and the only way I got it out was with a quality impact wrench with the air pressure turned up past spec (~130 psi).

The crank bolt on my old engine, I soaked that bastard with pblaster 3x a day for a week. It took my 300lb brother laying on the engine (it was blown up so it was sitting on the ground) and me jumping on a 1/2'' drive socket, 12" ratchet, 3' cheater pipe before that one broke loose.

i usually jam the flywheel teeth aty the inspection cover with a prybar or screwdriver, then use a big breaker bar to crack her loose. I do honda balancer bolts this way as well. You can also use this way to re-tighten/torque the bolt back on as well. the starter trick doesnt work to re-tighten the bolt.
