Is there a good way to remove a stripped crank bolt? My 6pt broke and spun on the bolt when I had the breaker propped against the ps frame... now nothing works... rounded off bolt. dangit. <img src="/forums/images/graemlins/scared.gif" alt="" />

Some options:
1. Weld a nut to the head of the bolt.
2. Pound a slightly smaller sized socket onto the stripped bolt head, or get one of those bolt-remover sockets.
3. Use a cutoff wheel to notch the washer and bolt flange and use a hammer and chisel to break the bolt loose with the chisel in one of the notches.

Air hammer with a sharp chisel bit, and an air regulator to keep it under control, and to use a minimum of force.

Thanks Roger! I knew I should have asked for a welder for Christmas I went and got a 6pt 3/4 socket... tapped it on w/a hammer. Nice and snug. Wish me luck. <img src="/forums/images/graemlins/shiner.gif" alt="" />

the 6pt 3/4 snapped like it was nothin... <img src="/forums/images/graemlins/scared.gif" alt="" /> luckily had a cheapy NorthernTool 6pt 19mm impact that seems a little under sized. Bumped the starter w/that on it and it came right out. <img src="/forums/images/graemlins/notooth.gif" alt="" /> Now on to the TC cover & headgasket replacement. <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />

Here is another, by cutting the flange it relives the pressure and you can remove it with your fingers. ![[Linked Image]](http://pics.montypics.com/oops/2006-09-18/1158584713_stripped_2.jpg) ![[Linked Image]](http://pics.montypics.com/oops/2006-09-18/1158584754_stripped_3.jpg)

On a related note, are crank bols on all engines supposed to be replaced every time you remove them? I know this is the case with the 5vzfe, but not sure on other engines.

My crankbolt was made in 1979. Pulley was removed numerous times. Maybe I'm lucky, but I do use the right tools on it, as well as the proper torque too. <img src="/forums/images/graemlins/wink.gif" alt="" />
