slanktapper Posted September 3, 2016 Report Share Posted September 3, 2016 I tried the search but nothing came up? I can't be the only one that's done this.... I've found some videos about rethreading a stripped bolt hole ( ) but it seems very sketchy doing this by hand, and I need to get what remains of that bolt out first. I have a stripped bolt remover thing but I doubt I'm going to get enough torque on it to break it free considering it snapped the bolt? So my questions are: Is there any way that I can get that bolt out with damaging the existing threads? Is there any way a professional can get that bolt out without damaging threads? Should I just take this to a trusted mechanic? Should I try to do this myself? Is a helicoil the only solution to fix threads? Any ballpark on cost for a mechanic? So here's what remains: Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted September 3, 2016 Report Share Posted September 3, 2016 Did you heat the case before you tried to pull the stud? Quote Link to comment Share on other sites More sharing options...

RIPPIN' IT UP Posted September 3, 2016 Report Share Posted September 3, 2016 Got a welder? Sent from my ZTE T84 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted September 3, 2016 Report Share Posted September 3, 2016 ^^ That's what I'd do. Weld up a stalagmite on whats left, then weld a nut on that. Remove with a wrench while still hot, but just back of cherry red. 1 Quote Link to comment Share on other sites More sharing options...
slanktapper Posted September 3, 2016 Author Report Share Posted September 3, 2016 Yeah a welder is probably next. We tried one of those bolt exactors last night... fcking snapped it too... Quote Link to comment Share on other sites More sharing options...
RIPPIN' IT UP Posted September 3, 2016 Report Share Posted September 3, 2016 Just jam plenty of rags around & over the crankshaft, don't want a single welding spark in there. Sent from my ZTE T84 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
registered user Posted September 3, 2016 Report Share Posted September 3, 2016 from experience I can tell you that one of them titan extractors is probly the best thing to use from the get go before you bust the stud. they grip a large surface area and clamps down near the bottom. another thing you don't want to do is turn the case on its side and try to turn the stud out or youll likely be applying downward force as well which makes it more likely to break off if that makes sense. small amount of heat from propane or mapgas might not hurt either but I wouldn't go crazy in one localized spot. another thing about corroded studs is they often times take the case threads with them which is another good reason to use a small bit of heat. if the stud breaks the last thing to use is one of them extractors. they wedge in there and expand the broken piece making it near impossible to screw out. before you crack the cases, if you haven't already, I would probly weld something to the broken piece the best you can. let it cool down and then heat the case material around it 1 Quote Link to comment Share on other sites More sharing options...
slanktapper Posted September 4, 2016 Author Report Share Posted September 4, 2016 Yeah i have them jammed with shop towels now, I'll swap em out for rags when I weld it. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted September 4, 2016 Report Share Posted September 4, 2016 I've used a welder 100 times , I've also jigged shit into a drill press and also used the tig arc to heat shit up , at 140hz it's a concentrated arc and a lot of heat then I'll mig lil dabs onto it . Just my opinion but I would tear it down 1 Quote Link to comment Share on other sites More sharing options...
