Some People Know How To Repair Damage Threads, DIY Make New Threads. Stripped Threads Remaking And Repairing Process. Subscribe To My Channel 😊 ⚡Zimbiker⚡ #motorcycle #repair #lathe #diy #threads
Working in a large aerospace machine shop, I constantly had to deal with stripped threads in the work holding fixtures that morons would way overtighten more than they needed to be. I started using the EZ-LOK thread inserts to repair them and never had bad results from them and the repair was often stronger than the original condition especially considering most of the damaged threads were in aluminum.
I like to use Helicoil. However, I use any solution, I never waste time making the insert myself, because it is very cheap and I can get them at any screw shop. 😁
Top notch technique. Repair is just as good as original without sacrificing ability to torque properly. Much nicer than just installing larger bolt after 1st thread tap.
@@bonerDB The consistency of pre-made threaded rods and bolts can be... lacking since some are really snug, while others are VERY loose! IF you use them, its usually best to stick to the same source to keep the source's threads and bolts consistent and (hopefully reasonably tight) However, I've personally found using taps and dies to be much more consistent and lead to better results
Silly me, I'd drill out the stripped hole, tap it and install a threaded insert, purpose made for the job, heat treated for toughness, and save myself a lot of time screwing around making one that won't be as good as one I could buy for .50 cents
Kent Moore tools makes a kit called a time sert. It comes with a drill bit and tap plus the threaded insert. Way stronger than a heli coil. Used in my career at GM
Project Farm did a test on this a while back. Both were even in terms of strength with the fasteners failing, but the time sert costs a lot more and is harder to replace if the threads ever get messed up.
Welding isn't good for repair like this. Putting heat in material you change physical properties. Even removing broken bolts by welding can weaken material. This technique is almost perfect and never disappoint. Thank you for remind me how to do that. Sub & like
These inserts can be bought hardened and self-cutting, sometimes even self-securing off the shelf. You can even turn them directly into a cast piece of aluminium just with a strong nut and bolt and a wrench.
True enough, though circumstances may make obtaining such a kit impossible. I, for example, had the thread to my old van's injector mount strip out and the van became undrivable, I didn't have such a repair kit, but I DID have the materials on hand to drill out the old hole, tap a thread and create an insert using a section of threaded rod, I drilled a hole through the middle of the threaded rod, tapped a new thread to match what it should have been and after applying thread lock to the outside of the new insert, I wound it home. That van already had in excess of 175'000 miles on the clock and it lasted another 35'000 miles before the old beast died a final time (not due to injector failure)
@@GaisaSanktejo That's amazing! I respect people that are creative with solutions so much! Still, if possible, there are some things that that you can buy and that make life so much easier. Like those inserts.. You can make them yourself and if you do, props to you, but if you can get them premade, it's great to have them.
@@KevinATJumpWorks Thank you and thats true enough, IF you can both afford and obtain premade items, go for it!. If not? You learn to improvise, fast 😆
@@GaisaSanktejo Actually, that 'doing things yourself' vs. 'buying stuff pre-made' is such a tricky topic. On one hand, one learns so much by doing stuff oneself, but on the other hand, you can operate on a more abstract framework if you can simply buy the stuff you need. You can focus on the 'big picture' without having to go super deep into every little detail. On the other hand, you might not get to know crucial details like this that, in turn, may slow you down in the long run. So difficult to navigate. But that being said, both perspectives have merit. :)
maybe it's already somewhere in the comments, but what did you use to secure/glue the self made outer thread / helicoil? and would it be durable or worse to use a piece of aluminium for the thread insert?
37 year machinist answering your question. I do this type of repair sometimes especially on a part like this. Either Loctite or a similar adhesive can be used. Basically superglue for metals if your not familiar. This looked like black Loctite which once it sets it has to be cut out. Heat will not even release that stuff. On this particular part that has a thin wall using something like a Heli-coil can cause the hole to break out on tightening the bolt as the coils tighten up in the hole and try and spread out. So a solid piece inserted and tapped is better. Also its a good repair as a part like this is rarely taken off and the steel threads will not gall like aluminum. Hoe this helps.
@@martinswiney2192 i dont have the years of experience as many others here, but i have found my thing in repairing old motorcycles for me and other people. I have used this method a few times but i glued it with blue loctite (learned from someone else) never seen someone back with problems but i never knew i made the right decision. Later i started to make them out of aluminium because someone said its really bad to make them from steel.
Question: Can I use the dye to replace a stripped nut...particularly if the threads are not aggressive enough on the replacement nut, and the axel although repaired, still has shallow threads.
Welding isn't good (I'm welder) (spawam rury na elektrowni) You put heat ( energy) in element and material in welded place isn't as strong as before repair. Taka metoda jest o wiele lepsza, bo zawsze bedziesz mial otwór w wymaganym miejscu no i nie zmieniasz właściwości (wytrzymałości) elementu
If true strength was required, if it was 5/16" or 8mm mangled thread should've drilled 5/16" pilot. Now make stud, one side 9.5x1.58mm(3/8"x16)the other side of stud 5/16or8mm dia, thread and cut for proper length with nut installed or just drill and tap for 3/8x16 bolt, done
good fix, but why did you not drill it out to a tapping size for a helicoil then insert a helicoil thread? The helicoil threads are stronger than the original thread.
@@capnskiddies I don't his location has anything to do with it. I have done similar with turning and press fitting a diameter into it because there was not enough wall thickness. Helicoil, recoil etc.. all provide worldwide. Nothing wrong with his repair except do we know the steel grade of that rod?
Maybe he can't get helicoils. Pretty sure that steel rod that he drilled and tapped is stronger than the aluminum it's being put in. This is a solid repair.
