Благодаря такому коленвалу кто-то влетит на дорогостоящий ремонт

главное появился ИНДИКАТОР ЧАСОВОГО типа и МИКРОМЕТРЫ есть!!!!!!! это очень зажиточные мастера, обычно циркулем на глаз посадки все делают и выставляют с точностью до сотки с помощью проволочки!!!!!!!!!!!! это уже мастера высшего класса!!!!!!!!!!!!

Even if this man is very skilled his work is useless, the crankshaft will break again right next to the weld.

Yes, this halfass patch won't last one good dyno run.

My Uncle Burt welded up our Cessna crankshaft after it broke. It runs like new!

If you pay attention to the video, you will notice that he's not repairing a single crank shaft. The place he's welding is not where it breaks. You can see that both cranks broke beside that where the journal joins the crank. He makes a pin on one side and a hole on the other, press fits them together, welds it up and turns down the journal. The point he repaired is supported by bothe solid metal internally and the main bearing. It's not going to break there. I think I can safely say I have never seen, or even heard about, a crank shaft breaking in the CENTER of the main bearing. It just doesn't happen.

Can you imagine their warranty policy? Ok I give you free 2 hour 1 block warranty which ever comes first.

Работа сделана хорошо, и соосность показали и биение в 1 сотку. Все отлично, даже заварили без пор, но коленвал от этого прочнее не стал, сколько он реально отработает. Это колено скорее все с дизельного с низкими оборотами двигателя, скорее всего даже дойц, они ходят в оригинале по 30 тыс часов спокой, сколько этот проходит?

But should adopt safety measures......

I cringed when I saw him brushing away those strips of metal with his hand. That's a good way to amputate a finger. Once you get a laceration from those, you won't try it again. (Fortunately, I didn't take a finger off when I did it)

You don’t need to worry about safety. You’d barely even lose a toe or an eye.

I'm not so sure it's going to break. Notice exactly what he is doing. That's not one broken crank shaft welded back together. That's two crankshafts broken on either side of the main bearing. Notice what he does. He makes a pin on one end and a hole on the other. Then he press fits the two halves together. Then welds up the main bearing journal over it. The weak spots are where the journals join the crank. You can see how it broke out there. Not where he welded it. I suspect they all fail like that, and most in scrap yards are there because that part failed. Otherwise he would have just went and found a serviceable one rather than having scrounged up two broken ones to make a whole one from. It's also a good bet you can't just go buy one.

It will break. The steel is definitively not the same in the crankshaft and in the welding, so it's a big fragility.

Crankshafts are made from mild steel, not very different from a welding rod. The only unknown is the metalurgy at the weld spot, the parts being welded are massive and temperature can't reach levels comparable to a furnace. Most likely, the engine that will be repaired with this cheap part is so old and decrepit that it will fail before the repair fails.

Мартышкин труд, лопнет эта порнография под нагрузкой тем более на дизеле, про закалку шеек коленвала в тех края похоже даже не слышали.

Mindblowing

I have a better question: how can a crankshaft be broken?

Could be stronger using jb weld in the bore

Подгонка напильником наше фсё!

Как думаете: какая была нагрузка, если лопнул коленвал? Не полуось, не валы или шестерни в коробке - коленвал! А может быть, он лопнул после такого вот ремонта?..

Thank you for showing your response and and answer of your question is that Implementing heat treatment after the boiled neck incident is crucial to address potential issues. Proper heat treatment can enhance the structural integrity, minimizing the risk of the liner turning or experiencing a repeat burst. It's an essential step to ensure the long-term reliability and safety of the equipment.

You guys are all just haters. Anybody who can run a manual lathe like that is a boss. And with half a cig in his mouth. The crank will break again no doubt. But he did have some mad operator skills. Wait..... He did that in his pajamas and flip flops.....with an electrode bag to cover his bare feet while holding his welding shield on his knees and threw down one hell of a bead Damn

Вот не думаю что они на столько тупы и не понимают что коленвал лопнет,но на какой-то хер варят его хотя глазом видно что биение на токарном присутствует
