Thumbs down Stripped out threads, boooooo

Ok heres the situation, im a moron and stripped out one of the threads on the top of my supercharger ( 1990 Supercoupe ). It is one of the bolt holes for the bolts that hold down the actual supercharger Top ( says 3.8 on it). Its supposed to be torqued about 15-18lbs .......so i think i can re thread it somehow but i dont know how.

someone recommended me to Heli-Coil {sp?} or something like that. Its a small kit that you buy to repair stripped threads. I need to know where i can find this kit or something similiar...thanks alot!!

thanks again

at most harware stores, lowes, home depot etc. You can get different sized taps, while it isnt really very good for making a complete new thread pattern it will bore the current one out a little better. I think they are made of hardened steel. If you break that thing in there you are gonna be fubared. They are relatively delicate. What you do with them is screw it in 3 turns screw it back out 2 turns. This will prevent alot of the friction.

That happened to an engine I worked on last summer. Take the bolt with you to the auto parts store so you will get the right size heli-coil set. You will need to remove the SC Top and upper IC tube all at once. Be safe and cover the open SC hole with an even layer duck tape so nothing can fall inside when you start to drill and clean metal shavings out of the hole. Be sure to drill the hole deep enough so the heli-coil will screw in below the surface. It is actually stronger than the original. Good luck

I've got an easier solution. Convert your bolt to a stud and nut. JB weld it in. It will be plenty strong and you don't have to bye special tools.

For what it's worth, the SC top bolts are 8X1.5mm. Get a helicoil kit with that size, and a... 21/64ths drill bit.

As someone mentioned, the heli-coils are somewhat delicate...that is the tang that drives the coil in is prone to breaking. Although, the screw in, screw out method is incorrect for the coil itself. This is proper for the tap. You must drill out the hole to the proper size for the tap included with the heli-coil kit. If you don't do this, the tap will not make correct threads. This specific size drill may be included with the kit, but if it's not, the size you are supposed to use is listed on the package. Do Not Substitute The Size! Buy the correct one. Make sure you start the tap straight, it takes some practice to get it in right. A tap wrench helps and you will certainly increase your risk of breaking the tap in the hole if you don't use one. A lot of people use an open end or adjustable wrench to drive the tap. I wouldn't recommend it.

Once you get the hole tapped, use the special tool to drive in the coil. Make sure it is flush or slightly below the surface. Then break out the drive tang in the bottom and viola! You are done.

I wouldn't use a stud and I certainly wouldn't use JB weld. Nothing more than jury rigging in my opinion. Plus it just plain looks bad.

Hope this helps...

I agree with Tony... my Craftsman tap set has gotten me out of a lot of binds. it's MUCH easier than replacing the bolt.
