Hi, all the bolts for the manual locking hub were broken and I managed to get 5 out of 6 out. As always, one have to give you a hard time!I first tried using a reverse rotation bit and then a screw extractor. All 5 came out easy but on the last one, the extractor broke inside the bolt. I tried drilling it out but it seams to be too hard of a material. I drilled a smaller hole right beside the broken extractor and used a smaller extractor while applying a little bit of heat, nothing happened, tried again and the extractor broke and now I have no way to get them out or drill thru them. I then used my welder to build up material on top of the bolt in order to try get enough material so I can weld a nut to it but that broke too. What can I do? Thanks.
I have always used a small punch or chisel to remove the bolts. Very seldom do I use a drill. But when I do. I center punch it very clearly and drill slow. Use a lot of WD-40 and try not to force the broken bolt out. So I don't break the easy out off. You can apply a little heat to area to help losen the broken bolt.
Keep welding and break off it will start to take bits of the easyouts off and it will come out !!!I do this all the time at my work really a pain but keep at it!!I ALWAYS tell my customers DO NOT try the easyout bring it to me first and avoid the extra cost of me having to remove both the Easyout and the bolt!!I had a customer that had done what you did and took me about an hr to remove but I got them out!! If that don't work I have had to use a torch and blow the bolt and easyout out U must be carefull and not really mess up the part but it can be done!Good luck, Bradley C
Thanks to all for the replies!I tried the heating method but didn't work and the used the welder (more heat) and It didn't work either. I made a small grove on the side of the bolt and used a small chisel to try to turn the bolt but nothing. The bolt have being soaked in PB blaster for at least 2 Weeks so penetrating oil is not working.Tried titanium and cobalt bits but they won't drill the easy outs So I think the options are:- Retry the welding method (spent about 1 hour and 8 nuts )- Try to find a diamond / tungsten carbide and try to drill it out and the use a heli-coil to replace the threads.- Buy the upgraded 12.9 bolts (which I will be doing no matter what) and run only 5 bolts instead of the 6. - Buy a new hub
DO NOT USE BRAKE CLEANER PRIOR TO WELDING !!!!!!!!!!Especially if using ARGON as a shielding gas. ONE tiny wiff could KILL YOU !!!!and NO I don't know this first hand....or i'd be dead PLEASE READ THIS !!!http://www.brewracingframes.com/id75.htm
I frequently use brake cleaner prior to welding.....#1.....I use CO2 as a shielding gas.#2.....I blow dry the metal with compressed air before I weld.#3.....Unless you are using the exact same welding setup as in the link, and you don't bother to evaporate the brake cleaner prior to welding, then you don't have anything to worry about.
So, you don't think it's good information...on the chance that #1....you, or someone else "might be using Argon & brake cleaner? #2....You have just advised someone else to clean up penetrating oil from DEEP around a bolt, where it would be difficult to "evaporate" the brake cleaner? It doesn't have to be the exact same welding setup. just welding "heat" + "argon" = phosgeneFOR WHAT IT'S WORTH
....DON'T GO SWIMMING IN THE OCEAN....THE SHARKS WILL EAT YOU!!!!!!!!! ;)
