while tightning the cam caps, i must have not felt the torque wrench click, and i was starting to wonder why it had not clicked already. so i thought i would trust the torque wrench and kept pulling.

it broke the bolt. the head, shaft, and about 4 rows of threads are broken. the remainder of the threads are in the head.

i started to drill a very small bit into it, but stopped because i didnt want to **** anything up.

basically im asking for ideas on how to remove the remainder of the bolt thats still in the head.




circled in red is the location of the broken bolt.

 

well..now that the bolt is useless...just grab it with a pair of pliers and twist...do this with all of the cam caps off though!

 

why not take a pic of the head so we can see how far down the bolt is

 

its about 2 or 3 mm in the head. not very grabbable.

 

get a "easy out" 1/8"

drill down the center of the bolt and thread this in, its reverse thread so it'll pull that broken piece out.

also cover everything with rags and tape off the area, so you wont get metal shaving in the head

 

thanks alot! ill try that. any other ideas?

 

Your best bet would be to take it to someone and have it helicoiled. I noticed that you live in NC. Darrell *** racing in eden can do it for you. If you need his number PM me and ill hook you up. Good luck on whatever you do though

 

if you arent confident with yourself taking it out with the easy-out, a machine shop will do it for a small fee.

 

the threads are not stripped, but the bolt is stuck in the hole. i got the easy out, and im going to give it a whirl.

 

snap on has a tool for this, call them up, they my have a truck to come out and help you

 

Left handed drill bit, if that doesn't back it out for you when it bites...which it probably will...then move to the easy out. If you already are going for the easy out first, stop if it doesn't come fairly easy. If you break that thing off in there you are screwed as you won't be able to drill into that. They come in pretty cheap kits of 5 of each (left handed bits and easy outs) in different sizes and are essential to any toolbox's "oops" drawer. I did the same thing once....yuk. My bum inch pound wrench also decided to go out of callibratation every third use and snap bolts as well....Matco finally replaced that, whoo hoo. The Snap On style with the wheel on the side are pricey but worth the money. Good luck.

 

I don't have a solution for your problem Daniel, but if you need someone to stand around and drink beer while you try and fix it just let me know.

thanks to everyone that responded. i tryed the easy out. and yea. it broke off in there.

so i had to take it to a machine shop that put it on a CNC and used a carbide bit to get the bolt out.

a $50 mistake
