Just like the title says The Arp Crank Bolt bottomed out for some reason and it broke inside the crank, it's the last 1/4 in. of the crank and it's way in there I already drilled the middle with a 11/64's i believe and i am using the #5 Extractor. should I drill some more to use the #6 easy out? or keep it as is, the only thing is that the extractor is still a good 1/2-3/4 in. within the snout do they sell and extension to get to the extractor and start turning it? thanks,

Ouch, I feel your pain man.

I had the same problem about a year back, and even a local machinist couldn't get that piece out. He ended up rethreading the 3" or so on the front of the crank snout to take a larger bolt...

Maybe you'll have more success removing it than I did...

 

No, one else?

 

eddie how far in is it need to see what i have in the toolbox to try and give you a hand.

what ever you do do not break the Extractor, Good Luck sorry to hear about this type of problem....

 

looks like i'm gonna have to drill the whole thing out!! I"m gonna need a 29/64ths drill bit and a m16x2.0 tap anyone know where I can get these relatively cheap? home depot? lowes?

 

I doubt home depot or lowes would have them. Try your local Napa, they usually have all the hard to find sizes, even if they have to order them. Good luck getting that sucker out.

 

That sucks bro.sorry to here it.

 

found it at napa! now i need the tap or should I use the Arp bolt as a tap?

 

Why not, just file down two sides of the bolt, and use it as a tap to clean the threads. Hope you get it out ok.

 

yea, I think that's what i'm gonna do

 

Arp Bolt is out!!! car was done yesterday at 2 A.m. feels good to drive again. I'll try to post some pictures up later on of the bolt
