hit it with a small torch and wick some candle wax into the threads and then use a vise grips to turn it out. ez peasy. haven't your been having a tough time with broken bolts lately? use a smaller wrench to tighten things up and when loosen them use a little heat first and turn then out gently.

No luck with Kroil and vice grips. No luck with using a dremel to make a slot and then use a screw driver. My first broken bolt. Al the rest came out pretty easy. |

I'm gonna try the torch in a bit. Got a buddy going to pick one up for me.

I welded two bolts onto it. Still no go.

So no luck with the easy out. I've put a torch on it. Nada. Nothing.
I need professional help. Anyone from the so cal area Orange County (currently sitting in Garden Grove) that knows of a shop or a person that comes out to do this type of stuff? This is gonna cost me. Worst part is it's covered under lifetime powertrain and I was just replacing before a bunch of long trips this summer. The dealer did it last 100k ago. |
did you try the candle wax before messing it up with the ez out (should be called never outs or difficult outs)?

Ok after a few beers I have some questions about trying to get this done myself.
To drill out this bolt straight what would be the best tool set up? I can run pneumatic tools but they seem like they might spin too fast. Diamond bit or carbide? in a few sizes up to just before the shaft diameter? Use calipers to make sure my last size bit is just before diameter of one of the other screws? Keep drilling it out until it dissolves or breaks out. Blow it all out with air and then re tap? Mopar 6101451 Hex Head Bolt and Washer, M6x1.00x25.00 |
Usually mild heat (torch) plus Kroil does the trick. Aluminum has about twice the coefficient of expansion, so heat the Al and heat-sink the steel bolt with a cold pair of vice grips, and try to turn it.
That failing, look up HeliCoil -- Basicially one drills out the bolt, including the threads in the front cover, to the specified size, tap new threads, insert HeliCoil, and it's better than new. Long time ago I even used HeliCoils on all 8 spark plug holes in some aluminum heads while they were off as cheap insurance. Edit: Regarding the drill bit, obviously don't break it off, get it centered, and don't go deeper than the original hole in the front cover. As to what drill bit type, take a file to the bolt and see how hard it is. If if files well, any good quality bit (not HF) will work. Avoid cobalt and other bits meant for harder metal unless necessary because they are more brittle and tend to break with a hand drill. Make sure it's center punched well before drilling. :cheers: |
