unscrew the broken bolt without drilling and welding, simple trick unscrew the broken bolt

[basspig]

I've never encountered a broken bolt stud that could be unscrewed that easily. Usually the studs break because they are stuck so tight that the force required to loosen them is greater than the strength of the bolt.

Когтями этого мастера можно выкрутить любой болт 🐾🤙🏻🔥

Те, кто сталкивался с подобной проблемой, знают, что этот простой трюк работает крайне редко .

In my forty plus years as a service engineer I would say I have removed maybe 50% of bolts like that but normally they are to tight to knock around, if you have a bolt that is snapped a good way down the hole a good trick is if you have a Lathe get a socket cap screw the same size and thread as the snapped one put it in the Lathe and drill a hole through the centre then put it in the hole were the snapped bolt is then using the same drill bit drill through the snapped bolt it allows you to get the dead centre you can then put penetrating oil down the hole and use an easy out. I always keep a selection of different size bolts ready to use works a treat.

Стакими ногтями его можно было просто ногтем выковырять)))

Показан очень сложный случай - обломок свободно люфтит.
Вот, если, обломок чуть прихватило коррозией, или на герметике - тогда, вообще, раз плюнуть!)))

Application of HELICOIL and punch-walking are two old-school crafts that were taught back in the early part of the industrial revolution. Schools used to teach these principles but technology has all but buried these common since crafts. My dad raised me in a machine shop, so He taught me these principles. I learned about HELICOIL application at my railroad career, and it's SO GOOD to watch it demonstrated on a free-to-watch video to the world! THANK YOU for your video !!!

Backwards turn drill bit will often spin those right out. The punch method I've used often as well.

Loved how he covered the chain with the rag and then blew everything in deeper with the air

Болтающийся остаток болта можно было выкрутить выверткой левой и не долбить полчаса. А с такими когтями можно было прям ими как отвёрткой крутить 😂

[phillipwatson]

To install a helicoil you have to first oversize the hole, thread and then put in helicoil. for the second bolt only one in a thousand will come out this way. A left hand drill bit will remove some and in the other case a small drill and an easyout will remove the bolt. If not drill out the hole with a slightly larger bit and either tap to larger size or tap and install helicoil.

Many years ago I had a stud break just below the surface of an alloy engine block. The guy who saved my bacon took a short length of mild steel flat bar, drilled a hole near one end, slightly smaller than the stud diameter. He then TIG welded the bar to the broken stud through the hole. He then just unscrewed it, the heat of the weld also helped free up the corrosion which caused the breakage in the first place.
My broke stud was held completely tight... the method shown here would never have worked.

Это просто фантастика. Жалко что такие заломыши встречаются в одном случае из ста из за того что это был говноболт. Обычно это прикипевшие, приржавевшие или обломанные из за того что не по резьбе закручивались и вот там всë это не работает. А вот удаление такого заломыша как в видео я бы и снимать постеснялся.

This solution is effective only in one case: when the bolt breaks off while being tightened, and when it does not rest against the bottom, after which, usually, the thread “unwinds” and changes pitch if the tightening was carried out without observing the torque. therefore, you first need to make sure that the thread has not “unraveled” on the broken edge. otherwise, when turned out, not only the pitch, but also the alignment will be destroyed on the upper remainder of the thread.

Маникюр ШИКАРНЫЙ... Где такой делал? Неужто там же, в том же салоне? Я на болтик даже и не смотрел. Да он от чертилки и так бы выкрутился... :)

I normally use a center punch to: A. Shock the broken bolt, THEN: B. use a left hand drill bit and SLOWLY drill at the center punch mark INTO the broken bolt. MOST of the time, the bit will bind into the broken part and back it out for you. If not, then you can use an extractor in the hole made by left hand drill!. TIP: A bit of grease will catch the shavings and keep them out of the engine.

Came here to learn something, what I learned is how to contain swarf within the engine using a rag and a airline 😵‍💫 top mechanic !

[paulkurilecz]

I generally go with the concept that if it is liquid it cannot be stuck. 🙂 Seriously, anybody who is working with steel bolts in aluminum castings should be applying an anti seize when assembling the parts. It will also help to prevent stripout when tightening the bolts.

[cdabg]

I'm assuming the bolt broke when tightening because no corrosion is present. Nice presentation on Heli-coil prep and installation. This person is well-experienced on proper tapping procedures of aluminum, backing to break chips and clearing chips before they score the new threads. Nice video!

Тряпочка конечно выполнила свою задачу😂
