theshee Posted January 30, 2007 Report Posted January 30, 2007 Has anybody every used a helicoil thread repair kit? If so how did it work out for you? I have 3 stripped clutch case bolts in my cases and need to repair them, will they work for this? Let me know your thoughts, or other ways to fix it. Thanks in advance fellas! :thumbsup: Quote
NYUK Posted January 30, 2007 Report Posted January 30, 2007 i have helicoiled holes before, they spin or pull out, i find it best to tap it to the next size up STANDARD. no drilling, just run the tap in there and find the correct bolt size. Quote
theshee Posted January 30, 2007 Author Report Posted January 30, 2007 Good stuff, thats the kind of info Im looking for. I thought about doing just what you said, but then thought maybe a helicoil would be better. Thanks NYUK :thumbsup: Quote
woodro77 Posted January 30, 2007 Report Posted January 30, 2007 i have used helicoils many times and never had one come out , they are stronger then just threads in aluminum, if it was me i wouldnt drill and tap because if it strips again your fucked , put in a helicoil Quote
locogato11283 Posted January 30, 2007 Report Posted January 30, 2007 i used a helicoil on a cr500 cylinder one time. it was where the outside fitting for the coolant connected to the cylinder. it held fine for as long as i had it. it actually worked better than the stock way it was. which bolt is stripped? on the bottom or top?

bigboybanshee Posted January 30, 2007 Report Posted January 30, 2007 i find it best to tap it to the next size up STANDARD. no drilling, just run the tap in there and find the correct bolt size. That's what I do too...when that option is available Quote
Duner440 Posted January 31, 2007 Report Posted January 31, 2007 On my old 400EX three of the valve cover bolts stripped out and I used heli coils in those and it worked great. I never had a problem with them. Quote
3 Posted January 31, 2007 Report Posted January 31, 2007 There is helicoil in a lot of aluminium part or casting who need threaded holes. They are a lot stronger than direct threads in aluminium so i would go for that fix. They are fairly easy to install if you have some skills. It's just tap or redrill the hole and tap than you install the helicoil. The only trick to it is to use taping oil at all the steps. Good luck man. Quote
FireHead Posted January 31, 2007 Report Posted January 31, 2007 On a lot of our lightweight, high stress engine parts, we design them to be used as part to be manufactured. Aluminum or magnesium threads just don't very long with steel fasteners. :thumbsup: Quote
Tim C Posted January 31, 2007 Report Posted January 31, 2007 Put one in for my intake manifold bolts and worked great. Had the manifold off and on a couple times after and had no problems. Quote
Ruko Posted January 31, 2007 Report Posted January 31, 2007 We use helicoils all the time.. they work great if installed correctly.. and they are easy to install. I once worked on an aluminum block out of a top fuel dragster and it had all the bolt holes helicoiled. Aluminum just isn't as strong for holding threads. Quote

theshee Posted January 31, 2007 Author Report Posted January 31, 2007 Sounds good, guess I will try them. I may as well, becasue the bolts arent doing anything now so even if it doenst work im not out anything. It is two top bolts loco. It wouldnt bother me but they are together, and i just want it done right. Thanks for the input fellas :thumbsup: Quote
scooter Posted January 31, 2007 Report Posted January 31, 2007 ive never seen a problem with heli coils if installed right we use them in our shop all the time. i know theres lots of knock off brands out there too dont know how well those work but the heli coil brand seems to work just fine Quote
'04limited Posted January 31, 2007 Report Posted January 31, 2007 i agree as long as helicoil is installed properly should be no problems i personally have used it more than a couple times. Quote
