Soak parts before removal with WD 40 and/or Break Free

Overnight

Get an Easy out bit/bits, drill hole in center of broken bolt(thats the hardest part)

use easy out reverse bit to remove bolt

When/If that doesn't work.

Drill out boss/bolt and re-tap.

good luck

Ugh. As mentioned, "easy out". Drill the center of the screw, starting with a very small bit. Use a drill press, if possible. Be gentle. Liquid Wrench is an awesome penetrator.

Good luck.

This is the right fix as AZbill recomends

+1 Easy Out.

Man, I wanna try to fix that... but I hope I never have to.

Good luck on this one EC.

EZ out is the way, but you can make life easier on yourself if you start the process with a left handed drill bit. Often the heat and friction of drilling with the drill will remove the screw and you won't have to go to the EZ out. Absolutely soak it with penetrating oil overnight. PB Blaster and Kroil are good ones. WD-40 is pretty useless, and I don't even think I own any these days.

Small EZ outs like to break. I have broken dozens of them. Once that is stuck in the middle of the bolt, you are in deep do-do with a flimsy casting like this. In a cast iron engine block or flywheel, its another story...

I think even Harbor Freight has left hand drill bit sets now-a-days.

Good luck!

Not true! WD-40 is good for removing ink, pencil and 2-sided tape and adhesives from hard, non-porous surfaces, without harming the finish. Yeah, I'm talking to you, "Goof Off".

I like the anti-clockwise friction idea, with the drill.

Yes, you are absolutely right!

We used WD-40 to remove the grease marks from the fenders of cars after working on them. It is great for that!
