Trans Coupler Stripped Bolt

So I am in the process of removing my trans and one of the 2 8mm allen bolts head is stripped. Im guessing the trans has never been removed because the other bolts thread were a bit rusty. Ive sprayed it with PB blaster and am letting it sit overnight. Ive also pounded a 10mm cheese head into it and am hoping I can break it loose. If that dont work any other thoughts? Im thinking drilling it out will take forever and require me to find a very long drill bit.
Thanks

If you go the drilling route, it might not have to be that long. If you drill the hex head off of it, you might be able to release enough pressure to slide the coupler back. you could deal with complete bolt extraction after you have it out. Is it the rear one? You might be able to get an air powered cut off tool in there to take the head off.... Hopefully the PB Blaster and 10mm cheesehead will do the trick. You might want to buy a small mapp gas torch at wal mart, and heat the coupler to increase your odds.

If you can get one of the bolts completely out, you may be able to drop the rear suspension, tilt the connected transaxle and torque down and then finally remove the transaxle from the drive shaft. You won't be able to pull the trans back since the spare tire wheel is in the way.
Of course, that's a lot of extra work. Before I did that, I would weld a tool into the offending bolt and try to remove it that way. Sometimes, sacrificing a tool is better than wasting an extra few hours of effort.

Good call guru.. I still havn't had my coffee this morning!
He may still get it with the cheesehead and PB / maybe heat. Fingeres crossed.
I have never tried using a cheesehead for that type of job, but I used to use the 6 point torx in the same fashion if needed.

Well the cheesehead was unsuccessful even with PB and lots of heat. Just stripped that guy right out of there. Next Im going to try pounding a 15mm socket onto the head and see if I can get that to work. The worst part is that whoever the engineer was didnt allow for a straight shot when loosening the bolt so your always at some type of angle even with a wobbly head socket. If that dont work Ill give drilling a try. This is no fun what so ever. 1 stupid bolt is holding up the 100 other things I have to do.

Unfortunately I dont have a welder however after the an hour of careful drilling...success. I got about 1/2" into the bolt and then was able to break it loose. Talk about a satisfying moment. I started with small drill bits and worked my way up to a 3/8" For anyone else who has to do this go get good drill bits and ones that are about 6-8" long. Makes life much easier.
Thanks to all for the suggestions

Go to sears and get the Bolt Out kit (I think its called the bolt out). It is NOT the nasty kind where you drill a hole and twist an extractor in so it can break off. Its like a toothed socket that you pound onto the bolt or nut and then put a socket on it to back the bolt/nut out. Its saved my butt a few times. The kit is $50ish I think but worth it.
Its called a Bolt Out or an Easy Off or something like that.

Funny thing is he came up with the idea as a teen when stealing wheels and needing something to remove locks. He ended up patenting it abotu 10 years later and the original drawings have saved his bacon numerous times. I had to testify to seeing the drawings back in 1990 in front of the Colorado supreme court
He is one of the only people to set patent law Pro Se (self appointed) .

I have also seen the spare tire well cut out to clear the TT with the coupler on but do that only after you have lost all hope and patence...

It think they are called easy outs. we use them in the shop all the time. It may help to drill a hole in the bolt first to get some bite. Basically it is a reverse rotation type hardened bit with a square drive at the end. The harder you turn in the unblot direction the harder it bites into the bolt. I have broken bolts and studs in half with these things... Good luck.

That is different
the easy out is for a drilled hole the lug off's, easy off,... "screw off's" (the original name) uses the outside of the bolt head and threads on in reverse while also threading itself on and tightening while loosening the bolt at the same time kind of like a reverse thread die.
