broken bolt extractor...help!

[anytwowilldo]

Lots of good info here and here is some more. If it were mine, I would attempt to remove the broken extractor by turning it CCW with a pair of small plumbing style vise grips. The plumbing style have rounded jaws not flat jaws. Use two hands and get the best bite on it you can. If you do get a good bite, it should come out fairly easily turning in CCW. If you can't get it out that way go at it with a center punch and knock it around from different angles to loosen it. If all that fails you can get a Dremel style tool and grind it out. As mentioned above, protect your eyes. Once out you need to deal with the drain plug. I would avoid hammering on it with a chisel as you can easily damage the case. I would run the appropriate size drill bit through it and extract the plug with another high quality extractor. I can't determine the scale but a bit somewhere in the 1/4" range may be appropriate. I would advance the bit slowly and in a controlled fashion and clean it often. The idea is to just have the tapered tip of the bit enter the crankcase and without bringing a lot of metal with it. After extracting the plug, I would use a small magnet to pickup the few metal shavings that did get in. As mentioned above, order the plug and crush washer now. Good luck. You'll get it.

That looks like it may have been a hole reamer, not an extractor. Hard to tell from the pic. Also looks like there is plenty to grab still sticking out. If it was a reamer it will need to be turned CCW to get out. If it was in fact an extractor it will have to be turned CW to remove. After it's out I would tap in a tight fitting Allen socket and weld in place. Then loosen using a quick pop against the handle of the socket wrench with a dead blow hammer. The quick pop usually works better than a slow twist. Not sure why but it just does. I call this "sneaking up on it" lol.

i hate to point this out, but extractors are reverse thread, so when you turn them ccw they dig/bite into what ever they're in & loosen that part, not the extractor. to loosen the extractor you'd want to turn it clockwise.

I'm thinkin (cause of what I'm seeing) that Angelsndevils nailed this with the hole reamer, ID.
And that tool has the teeth reversed from an extractors teeth, so...That changes all the CCW or CW directions.

You are so right. Mental fluke. I've done tap and die work for years and I guess I'm better at using them than writing how to use them. Thanks for straightening me out.
