getting broken bolts out of engine

Um, you (the original poster) might want to make sure the nitric acid, if you use it, doesn't go anywhere BUT the hole your broken bolt sits in - in other words, if it ain't a blind hole, another method would be preferable.

||Hey everyone, || ||I have a motorcycle with a problem. 2 of 4 bolts are sheared for an aluminum ||cover on the side of the transmission. 1 was broken when I got it, the other ||I just broke recently. || ||Actually, the clutch cable pivots on a post on the backside of the cover and ||since it's not JUST a 'cover' I want to replace these bolts, but I'm not sure ||how to get them out. || ||There's about 1/4" and both sheared rather deep in the holes. I've seen the ||little manual kits for $4 but I don't think I could center the drill by hand ||on a broken screw and the LAST thing I want to do is remove the entire engine!

Left-hand drill bit, with a brass tubing sleeve to protect the hole w/existing threads?

Doesn't sound like much fun :/ Texas Parts Guy

Yep. Chances are the existing hole is horizontal, and because he doesn't want to take the motor out, the nitric acid thing is a non-starter.

Chances are the 'weld on a nut' approach is also a dud because the fastener is broke well below the surface.

The 'drill it out' technique *might* work, if he has enough room to get a drill in there. Chances are it would be tight. Might also help to know what kind of bike it is.

Removing stuck fasteners is a snap - if the part is off the vehicle and in a milling machine. Once access gets restricted because the item is still on the car/bike it gets exponentially tougher. Because of teh restricted visibilty, restricted access, and the fact that one is reduced to working with a hand-held drill motor in most cases.

Might be able to lay the whole bike on it's side. Going a step further, position the bike so the hole is vertical. Then use a benchtop drill press.
