ran into a bit of a problem while removing the GM stage 2 pulley.

turns out that my dealer decided to torque the living hell out of one of the bolts. all 3 were removable except for that one. long story short, ended up stripping, mutilating, and completely raping that bolt trying to remove it (no i did not use a torx bit... doh!).

my question is, how the hell do i go about removing that bolt now?
i got some decent grip on the bolt and actually ended up moving the entire suspension on the car torquing on it and still no go.

 

They make drill bits that dig into a stripped head so you can back them out, I forget what they're called can someone fill in my blank? I think those would work for him but I can't for the life of me remember what they're called.

 

Try spraing some WD-40 on it, let it sit for 5 minutes, spray it again, let it sit for 5 minutes, then give it a try.

 

there's 2 bits that come with the kit and there not torx mt-2 why didnt you use them? or did you?

 

Try the WD-40, and a set of vice grips, if enough of te bolt head is exposed,

if that doesnt work, you can aways drill it out as stated

luckily Pulleyboys sells a set of 4 new bolts for ya pretty cheap

 

prob is im really lacking any bite with the bits i have ... well... by bits i mean screw driver head :P

.... what i really need is a new method for removing the pulley. i suppose i could try WD40.

the bolts are aluminum.... would an easy out still work?

thx for the input so far

 

i already picked up some new bolts from the hardware store
i didnt have the tool and didnt have the patience to ask my dealer for it. i improvised (not advised i found out)

 

Hey i looked and researched a little, PFI in fort collins might help ya out. 206-1029 for them

Or Redline motorsports 231-4938

or the RPM shop 267-9776

 

PFI also has a dyno so i may check them out as well

 

What I ussually do is drill a small starter hole, then tap in a sharp screwdriver or torx bit, then use that to slowly back it out

 

definitely let me know if u talk to em and they can dyno the cobalt

i'll give those shops a call. apparently u had better luck than i did finding shops... cant say i had much time to look very hard tho. thx brian

 

Hey, remz. Where do you live? I might be able to help later.

 

We need an easy-out for it or something, a proper set of vice grips would work but i didn't have any that would bite correctly on it. We used every tool i have and there's no way it was going to come out that way, we may have to drill it out but one of those shops should also be able to do it.

 

I worked under a diesel mechanic for a summer, and you havent experienced torque yet until you start messing with impact wrenches and cheater pipes that are taller than i am.

So heres my suggestion, PB-blaster and a cheater pipe. PB-blaster seems to penetrate a little better than WD-40.

 

The problem was that the dealer stipped the bolt when they over tightened it. Then it became badly stripped as we tried to force it out. Its more of a problem that we can't get a grip on the thing not that we can't turn it out.

 

fort collins

.... yeah.... i would rather not pay a shop if i dont have to. somebody with the proper tools could def help out

edit:
lol, badly stripped doesnt even begin to describe it

 

I live in longmont, but my tools are in denver. If it is drivable, try to come down to the rme shop. I bet we can get it off there.

 

if i have not figured anything out by the weekend, i will definitely come to the rme shop. thx man

 

No problem

 

I vote for the air chisel.... LOL. believe it or not that would either loose it or take the head off. the you may be able to remove the rest by hand or with vise grips.

 

That or dynamite! Either way. lol

 

All of these "suggestions". Here is what you do. You drill off the head. Just the head. Leave the bolt shank in tact. Then remove the pulley, leaving the remainder of the bolt behind. You will now have an exposed shank of the broken bolt. You now have two choices. You can lock the hub in place so it doesn't turn, and try spinning the bolt out with vise grips. Or you can get a screw extractor set. However, its a small shank, so I don't think your going to be able to get that way. If the vise grips don't work, you are looking at taking off the charger and bringing it to a machine shop for removal. Please do not try to drill the shank out of the hub. You will end up destroying it.

 

if all else fails (including dynamite), i could just huck my supercharger down a cliff and hope for the best

^ thx half cent. a little different approach that i really didnt think of. right now i think that would be my best choice.

 

Air chisel is what I needed/tried and it worked!
