Rounded head on flywheel bolt

[sherloc123]

so the genius that had the car before me rounded off one of the flywheels bolts almost completely. does any have any ideas on how to get the bolt out? Its the last bolt holding the fly wheel on and i really need it off so I can finish taking the crank out. Thanks

Drill or grinder bit.

 

[sherloc123]

yea i was hoping for an easier way then getting into that mess

Do you have a welder friend? You can have him weld a nut or something onto the head of the bolt and turn it from there, that's how I got a stripped off bellhousing bolt.

yea my buddy owns a welding shop its just a pain to drag all the stuff there. I know ive seen sockets that are suppose to pound on and grip but im not sure where to find them

Check these out:

Bolt out sockets

I've never had any luck with those sockets. I'd also suggest the "weld on a nut" method.

I don't know if the Bolt-Outs would grip well enough for a flywheel bolt's worth of torque. But it'd be worth the $20 test, I'd say.
Did you try the Vise-Grips, sized Big Gnarly?

They work, I've used them on flywheel bolts before.

Ah, Post #6. Great idea, last Wednesday. We wonder if they'd work under the amount of torque flywheel bolts are installed with. But I digress.

Air hammer or reverse drill bit are probably your easiest choices.

 

[Old Mitsu Tech]

Take a torch and heat the bolt head till it's almost red. This will expand the bolt and help release it from the flywheel. Using your handy dandy impact driver and reverse thread bolt removal tool. You know the ones with the left cut spirals, give it a hard rap with a good sized hammer and it should just come out. Be careful with the torch and use a welding tip. You only want the bolt head to get real hot. Not anything else. I've removed a bunch of them that way. This of course is assuming that the threads are intact and not crossed or stripped.

Good Luck

Gonna give these bad boys a try on my one rounded flywheel bolt

I'll let you guys know how it turns out.

 

[slowgsr]

weld a nut on, best way hands down.

or you can try your luck with the bolt out crap which im not a big fan of.

 

[Hiitman]

The bolt out crap worked like a charm. Alot less hassle then welding on a nut.

Ive had great luck with these, they even replaced one after I killed it.
