How screwed am I? Looks like pretty screwed.

Just had to do it last night. Just put some visegrips on it and spin it out. Mind you, thats a 1" bolt.

Well, I just picked up a set of left handed bits from harbour freight. The good news it, it worked pretty good, drilled right into the bolt, bad news is.. it didnt grab and spin it, and i think i drilled too close to the threads, i was off center. I tried hammering a star key up there with a ratchet, and got it in pretty good but when i was turning it, all I was doing was making metal shavings.

It seems the broken bolt and the block are now one. What do I do now? >.<
 
well, if you can, drill a pilot hole in the center of it, with a small bit. Then work your way up in bit sizes till you get to the size above the original bolt. Tap it and viola. Takes forever, but you may be out of options.
 
How far up would you say the bolt is broke off? Could you put a stud in there and a nut on bottom of starter and just leave the broken part in?
 
Demon, how much do you typically charge to get something out like that? I'd have to have the damn thing towed up to the shop but i figure it cant be more than an hour or two's labor. I'm wary of using an extractor, the hole i drilled is close to the threads and i cant get a good center hole laying on my back in the street. I dont want to **** up the threads.
 
I work for a mine so its all.part of the job. Jam an extractor in the hole you made. Use a hammer to seat it. Don't worry about the threads. At this.point. use lots of wd40 before hand to let it wick in. And try to get it out.

If you scrape threads don't worry. Chase the hole afterwards with a tap, see what it looks like with a new bolt threaded in. You can always helicoil it after if need be. I personally prefer timeserts. I can have a hole repaired with a timesert kit in a few minutes.
 
its a common 6.2 problem. done quit a few you need a long drill bit,too be able too drill straight. then with a small tube that fits in the hole,which you use too centre your drill bit.makeing sure you have a right size easy out for the drill bit. people did but loctite on these bolts because they would fall out or break,go too a shop if your not well equip them holes are in the block. if you screw up the holes you screw up the block. once i had too install helicoils because of a guy screwing up .:dunno:
 
At this point, it's more important to get the bolt out of the hole. Than worry about hurting the threads. The threads can be repaired.
 
had the same thing happen to me go get a left handed drill bit from home depot and save the headache of the tapouts.
 
I've had a bad day with similar circumstances as the OP here.......been trying to remove a great running 8 HP B&S engine from a chipper-shredder ,a Crapsaman POS...I spent all day welding washers to a nut and then the washers to the chipper wheel in hopes of being able to pull the wheel off by screwing in a bolt,using the air impact if need be.................................................................................................................so far I've stripped a 5/8" nut out and several bolts,then I welded a 1/2" nut to the stripped 5/8th one and proceeded to strip that one right out instantly...by then it was getting dark,I used the torch to cut the 5/8" nut off so maybe I can start over tomorrow...I bet the cranksaft is mushroomed some because it has a 3/8x24 threaded hole in it to hold the chipper wheel on it--no allen head set screws ..a sucky design that may never come apart or wont until the engine is JUNK.........................................................................................................I'll probably have to carve away the chipper wheel with a torch until all that remains is the center hub,which is real thick and will suck to cut with anything and not gouge up the crank or bend it...if it aint already bent...wasted a whole farigging day,several welding rods,oxogen is almost gone in my torches..my "free" perfect running engine might end up scrap iron after wasting my money and effort trying to get that dam chipper wheel off it...nothing free ever IS it seems.........................................................................................................................................................................................................All I can say is GOOD LUCK getting that starter bolt out..I have very poor luck removing busted studs and bolts ,I wont even attempt using an E-Z out again after snapping several off in the bolt ,IF I managed to drill a hole in it anywhere near the center...it sucks,you get ONE shot,if it comes out off centered,your boned usually--only method I had any luck at all with was welding a nut to whats left of the busted bolt,if possible................................................................................................................I've had to have blocks welded where the starter bolts went when removal attempts failed miserably-one the tap broke off in the "new" hole we drilled in the process of removing the bolt also removed the threads,leaving a very thin walled hole in the block....someone with more skill and luck that me arc welded the block with nickel rod,re drilled and tapped the hole for me in like 20 minutes...while he ribbed me for screwing it up so bad,and asking "why didn't you just have ME fix it"??.....why???..M-O-N-E-Y,that why...luckily he was in a good mood that day and a six pack and 10 bucks was the penalty for "ruining his afternoon"....
 
i'm from wisconsin where they use salt on the roads and evey bolt freezes up. what i do worst case is get a colbalt drill bit for grade 8's then easy out with heat around outside area and if that still dont work, drill it out trying to keep it centered. if not centered drill under sized then finish with carbit cutter on a die grinder/dremmel. then re tap or drill it over size for an insert or helli coil carbite cutters work great to center it up. grainger is a place to get carbite cutters and inserts. using heat helps to but be carefull acetylene and oxygen with a small tip work best with just a little red area will free up the threads

I think it's beyond my skills or drive at this point. I wish I had a lift, or it wasnt cold out at least. She always breaks something at the right time haha. Between finals for school and work I hardly have time either. :/. Itll prob end up at the mechanic if its not an arm and a leg
 
Is there any danger in arcing a bearing in the engine when welding on to the bolt like was suggested earlier?
 
Update: I got it to the mechanic and they said it doesn't look good and are looking at "other options" My attempt to use a left handed drill apparently made it worse on them. If they can't get the bolt out of the block.. are there any other options besides taking it to someone else? I can't believe a bolt like this can take an engine with 60k miles on it junk..
