alternator bolt broke off in engine
My girlfriend has a problem. The bolt that holds the alternator to the metal piece on the top of the alternator snapped. This did not seem to be a big problem. Got the replacement bolt from the auto store. The problem occured when I tried to put the new bolt back in. When it snapped it looks like the alternator was pulled down by the belt further tightening the only remaing bolt holding the alternator on (the big bolt on the bottom). This added stress caused the big bolt to break off. Half the bolt is broken inside the engine block(?) in a very inconvient place (one of the wheels the belt drives is infront of the hole the bolt is broken inside of. I imagine it is in there extremely tight. How would one go about getting it out? What would a mechanic do? I don't see how it could be drilled out, being in such a crowded place, with out disassembling most of the car. Any suggestions would be appreciated.

Re: alternator bolt broke off in engine (fslim)
there is two option but you have to be very careful:
1. weld another end of a bolt to it and try to take it out that way.
2. there is a kit at the auto part store you drill a hole into the screw and the harder you turn it gets tight and turns the bolt out. forgot what it is called hope someone on the board rememeber.
good luck

Re: (Beach Accord)
Removing the motor mount would deffinetly help and then use a floor jack to raise the motor a little bit. If it was the shop that i'm in we would first try welding some kind of stud onto the broken part of the bolt and turning it that way. If that didn't work we would probably drill it out. I THINK i heard somewhere something about a 90 degree angle drill bit? anyone ever heard of these?

Re: alternator bolt broke off in engine
This is like a thread from 10 years ago.....and no one ever gave a year or engine.
Anyway, any "good" parts store will have grade 8 bolts in a wide rage of sizes. If you have the pieces of the one that broke, take it in and get them to match the size, pitch and length.

Would your car happen to be a 98-02 Accord V6? The alternator mounting bolt or bracket can break if the mounting bolt was cross-threaded or not torqued to spec. when the alternator was installed from some work done previously on the car. Honda issued info. regarding the improper install of the alternator mounting bolt before on the 98-02 Accord V6.

If you need to extract the old bolt you need to buy an extractor kit from any auto parts store or hardware store. Then drill a hole that is the size of the extractor from the kit you will be using. You drill a hole, then using a hammer you tap in the extractor, then turn the extractor out, and since the extractor is lefty tighty it will eventually pull the old bolt out.
There are how-to's on youtube for how to do this.
