New tool added to the arsenal. Stud / broken bolt remover.

[STINEY]

While we were replacing the water pump on my sons '78 Buick Regal Sport Coupe three of the 1/4" bolts lost there heads. Fortunately a lot of patience and wiggling got the pump off over the broken bolts, leaving nearly 1/2" of bolt to get ahold of.

Good enough reason to buy and try a new tool, right?




The first one we tried broke off flush (of course), but the last two actually came out with no further damage. I call that success, especially on a 40 year old Ohio car with the original aluminum pump. With the aluminum body / steel bolt corrosion you just KNOW those tiny bolts are gonna give up the ghost.

Just wanted to share this. Its similar to a drill chuck, one tightens it against the stud / bolt with two wrenches on the hex parts of the tool, then uses either the ratchet drive or the hex part to turn the tool. Doesn't try to slip like vise-grips will.

I have one of these and it works awesome.

I actually have one like BBR's, and had horrible luck with it. Trying to pull a stuck stud from a motorcycle crankcase, and that tool bent the stud really badly. Was going to be replaced in any case, but the job suddenly became massively more difficult. Finally wound up having to pull the motor, split the cases, cut the stud off slightly proud, and made a guide that fit over it so that I could drill it, which probably added about 40 hours to the rebuild process.

Never again. I could see trying the other type, though.

That's an interesting idea. Wish I'd seen this thread before I paid a machine shop to remove a pair of stubborn broken studs; it looks like a promising idea!
