The Stovebolt Site Forums The Shop Area Engine Shop Broken Motor Mount Bolt in Bellhousing!

Well there it is, my worst fear. Trying to replace the rear mounts and found a bolt sheared off in the bell housing. It's about 3/8-1/4" in from the edge of the block. Any suggestions on trying to get it out? Not really room to use a drill/extractor. Bummed

If you can clean it up enough to weld a nut to the sheared off section, you may get lucky.

Long shot I know (recently replaced one of the vertical bolts in my rear mounts and it's a tight area) but perhaps a 90 deg. offset 3/8ths drill, either air or electric and a short drill bit?

Is the bolt threaded into the bellhousing? If so, the only really effective way to deal with it will be to remove the bellhousing and get it set up firmly in a drill press. You'll only have one shot at drilling it out on center without damaging threads, and once the hole wanders off due to an awkward angle with a hand drill motor, there will be no way to get it back on track. Then you'll be shopping for another bellhousing.

Jerry is right, the best way to get to it is pull it. On the other hand, if you had a dental tool and could see in there well enough to grind a hole in the center deep enough, you could do that and possibly get it out with an easy-out. That would probably take almost as long as dropping the bellhousing though. Bummer though!

We made brackets on a gun engravers ball (vise) to mount it on the vertical mill table. It can be swiveled to any angle including compound ones and use it just for bolt removal. With an end mill it doesn't make any difference if the bolt is square or angled on the broken end as the end mill won't "walk" like a drill. Once a year we have an open house for the AACA members in our chapter where the guys come in on a Saturday to do small projects free. The two busiest projects are bolt removal and Flat head Ford distributors on the Sun machine.

Well, very happy to report that we got the broken bolt out. I ran to my local hardware shop and picked up a short 90 degree attachment for my drill and the tight working space, along with a screw/bolt extractor kit. I wasn't so sure about it, and initially it was taking time just to put a mark in the snapped end. Once I put some real force on the bit though, voila it backed the piece right out. Never been so relieved. Keeping the bit as a reminder, it's not always the end of the world.

SWEET! love it when things come apart easily!

Either you are so lucky that you should get a stack of one dollar bills and start handing them out to strangers, or you are so good that you should not let anyone talk to you.
Nice to hear either way.

Guess I better get some $1s, except they're coins up in the north and we call them Loonies.

Sorry Goach, I forgot that you were Canuckian. Loonies it is then,
I just Googled the Loonie. That is a beautiful coin!
I wished that us Yanks would get rid of pennies and one dollar paper money, and go with an easily discernible one dollar coin.

No apology needed; we also have "Twoonies" and you wouldn't believe how heavy our pocket change is now!

I realize you have gotten the piece out, but get a set of left hand drill bits, often the broken piece just comes out while you are drilling the hole.

That's exactly what happened. The extractor has a drill bit on one end and a bit to 'bite' in on the other. The drill bit backed it out by itself.
