You stripped out a bellhousing bolt? What the hell did you do, put a breaker bar on it and stay in it?

Simple go to the parts store and buy a heli coil kit for that bolt and thread size. The kit comes with a tap and coils. Dam . I hate it when I am always right. :laugh:

Yep that simple. I have done it before, not on that bolt though and they work great

shit did you crossthread it or something

were you using a 6 point socket?

try using a torch to heat it up and then snap a vice grips on it

If vise grips don't work, get some Craftsman bolt out. Worked great on my stripped tranny fill plug. 30 bucks at Sears.

whats a bolt out? extractor?

So you are saying you didn't round off the bolt head you actually stripped the threads in the hole?

 

[oldman]

I've never taken off the motor mount so I don't know what it looks like. You can try,

1. A slightly longer bolt.

2. Run a tap throught it and see if you can fix the thread.

3. Drill and retap to the next size up.

If I understand you correctly you tore the threads out and can no longer use them. A common fix is to use a "Helicoil" which will work though not my prefered choice. It comes in several sizes and frequently requires a special tap and possibly a specialty drill bit to make new threads. The coil it's self is made from a diamond shape wire rather than being round, this allows the wire to partly sink into the oversize threads and thus restoring the inside diameter to the correct size and pitch.

Alternately you can re-tap for a larger / longer bolt.

A far superior repair and my choice is to use one of several products identified as inserts. These are threaded sleeves some of which use standard tap and drills plus no special tools to install.

There are essentially 3 major players in these, Keensert, Slimsert, and Timesert. They may all be owned by the same company but each has some special features or ease of installation. You are lucky in that the engine is out of the car thus every opportunity to do the job under the best of conditions. I cannot stress the importance of being patient with yourself ... don't be in a hurry allow 1-2 hours and you will have a professional job that will outlive the car. Sure you can go in the closet and kick yourself a few times and try to not repeat the mistake again but this is well in your skill levels to do at home. They were developed from the Aerospace industry where stuff happens and they can't afford to discard a multi million dollar part just because some bolt broke or stripped.

vfaq also has a guide to removing busted bolts under the misc section


i would say from expereincce that themost important part is drilling dead center in the busted bolt

umm.. I think he didn't break the bolt, he striped the thread.

Understood, yet a member asked a question and while it's possible to cite past experiences it would be proper to have skilled objective information that the person in trouble can use. I am not a rep for any company, but my experience has taught me how best to recover without spending great sums of money.

tap the damn thing. =P and next time dont cross thread. if it doesnt go in that easily, dont force it.

 

[Defiant]

And do NOT cross-post.
