The top gear which was broke due to overload was very well attached
I really liked the part where he cleaned all the grinding grit out of the input shaft bearing. Great work.
That input what bearing needed the extra material, it's down two or three rollers already. Probably the cause of the first failure
This guy is a genius, he found some broken part "fixed" it and probably threw it straight in the scrap bin when it was done, but he got 7.5 million of us to watch the video and banked the cash😂
WORD. 💯
That is why it is silent movie !!
That's Google for ya. But: lf you saw it on the intercom know it's true.
The whole time the bearing on the end never moved probably because it was full of slag.
The bearing was missing rollers, it was shot.
Whenever Safety Sandles are involved you know some stuff is getting fixed 🙌 No trips to the part store needed here 🎉
No hair on the top of his feet
Don't know how reliable the finished product will be, but I do admire the can-do attitude and the work involved especially in the conditions available.
I suspect the repair would be stronger with a brazed joint.
As a lifelong welder, that ran a fabrication and repair shop for 45 years, about the first time he accelerates, that thing will go pow, right next to the weld! There are some thing’s that shouldn’t be welded, and that is one of them. Like Clint Eastwood said, “A man has to know his limitations “! 😂🤣😂
As a physicist and engineer I approve his work, you're wrong.
@@rafars2246 completely agree with you. Here in America we believe new is the only viable option. In many countries they have to make do with what they have and I feel the time spent on doing this job shows that it will last.
@@acetech9237 that was a full melt job, compressing the area, that "weld" is stronger than the rest of the piece. And they do it for a reason, because it works for many more years to come.

Nice ste up, gear in 4 jaw. Nice ground through ur lathe bearings. No concerns for spatter or lathe bed if ur ground through the dam thing. Mighty soft shaft for that drill to go in so easy. That input bearing has nothing to do w failure. Precision cut splines. No run out. Man I love these videos, makes me feel like I can mig steel to alum!!!
exactly. All that metal being thrown into the bearing made me cringe. That weld job is shit too.
I thought the same thing about how easily the drill went in. The shaft appears to be cast, and given this overall operation, it's probably cast from grab-bag metals.
Shafts are usually induction surface hardened (or flame hardened, back in the olden days), so it's not too crazy for the center to still be machinable.
I think this video is very good. We have similar machines. If you are interested, we can talk about it together
Reminds me of back home! All parts are at least 80 miles away and some are hard to get. We have to 'temporarily fix ' stuff just to get the equipment back home. It's amazing what you can fix with a little ingenuity. Parts only temporarily as no heat treat, welding through the bearings, metal grinding particles in to bearings, ect. Only temporarily.
As one who is skilled both as a machinist and welding, I am impressed at what this man was able to accomplish with bare bones tooling. Being able to center that shaft in a four-jaw chick with no dial indicator is admirable. He is making do with what he has. The only doubt I have is whether or not that repair is going to hold up. I wonder if he had the ground clamp on the tailstock? You wouldn't want it on headstock with current running through the bearings. That's the kiss of death for any bearing.
As a machinist, I too was impressed by his use of a 4 jaw chuck. His carbide cutter was under-center, leaving a nub. I had to laugh when he tried to drill into it. He cut the video there but I'm sure he had to put a center drill in to keep the drill from walking. Waste of time to try that without it. And many guys don't use lubrication in their cutting tools but damn it irritates me to see that. A bit of oil would have made the process so much easier
You're a skilled a machinist and welder? I wouldn't want to use anything you've worked on if you think this is in any way a good repair.
Can’t imagine anyone believing this repair will last very long. Love how he used his cutter to guide the drill.
The guy can’t go to Kwik fit for a factory replacement…we could teach him a few things about practices ,but he could teach us a load about real engineering..
@@griswald7156 That's the thing. Americans think that they own the crown when it comes to innovation when in fact, most of America's most ingenious inventions were created by immigrants.
@@griswald7156 I don't know about that. I realize he's doing the best he can with what he has, but that repair simply isn't going to hold up. Plenty of shops here could do that, they just don't bother because they know it won't hold.
Depends on the parent material and the material used to weld. Also, he might add a post weld heat-treatment -probably not going to be done, though (Joining Technologies).
@@SealofPerfection It also depends on the application. No, it wouldn't hold up in my muscle car with 450 foot pounds of torque but for a little old lady going to the grocery store once a week, she's probably good for the rest of her life.
Many of you guys commenting here just dont get how things work in the developing world, yes the gear shaft will almost certainly break once again though not before they cover a good amount of miles and when it does break they will machine and join it all over again. These guys have been doing these kinds of repairs for decades and are experts in their craft. Buying a new shaft would definitely cost a lot of money so the best option is to continue down this route until the shaft is basically all worn out and cant be machined any more.
The premise of the repair is sound however I actually laughed openly when he brought out the zip disc grinder to start cutting the shaft grooves. Necessity is indeed the mother of invention. We can laugh all we want, but if it works it isn't a fail.
Under those primitive working conditions, I give the man lots of credit. He's taking care of business and not sitting on a street corner begging like some bum. Hats off to the man.
Be kind and donate a 3-D printer to them.
Maybe the bum is an electrician with no job. So easy to call other people bums.
He's a good hard-working man--and very skilled mechanic / machinist. RESPECT!

I congratulate you for this work, and I don't think that after welding the shaft you are going to throw it straight into the trash. I am currently older and retired, but in my youth in my country, Spain, for many years I have been an assistant on a lathe-operator, and we have done the same welding many times, of an output shaft of the engine flywheel towards the clutch or of a front or rear shaft of a four-wheel drive, previously making a centering bit and then it works perfectly !! congratulations for the fantastic manual work
I like how things sometimes last forever that naysayers condemn. Hope it was successful. PLEASE DO A FOLLOW UP.
Nice shiny paint job ... Now sell it 'as good as new' to some sucker. Love the grinder's abrasive dust and removed steel fragments shooting into the bearing!
I see a lot of comments about the grinder grit getting in that input bearing. That bearing is Toast already, notice the rollers are rough and unevenly spaced and the roller cage is totally gone. The thrashed bearing was likely the cause of the snapped input shaft in the first place. If its not replaced there is Zero hope for the spline repair.

@@rizalmintarja6763 8
welding spatter was also an issue when welding.
Did you also notice the condition of the nose of the shaft? The flywheel bushing isn't going to survive very long, either. At the very least, it's going to squeal like a tortured pig when the clutch is in. But it also won't keep the friction disk centered. Once the friction disk starts going off center, it's going to stress that shaft again.
rolki są nie równo rozmieszczone bo dwóch chyba już nie ma :)
This guy will repair this particular piece every single day.
Looks like the bearing on the input shaft is missing a few rollers. Wonder where the ground path is through for the welder? Must be just great for the bearing to have all the grinder filings to be flung at it. I've never heard of an input shaft breaking like that before.
I sure wouldn't want all that welding spatter all over my lathe.
This video was repairing the first weld.
"Been there, done that." It's what you do when you can't get, or can't afford the replacement part. I'll bet it worked fine. Good ole 7018 welding rod.
GROAN! All that grit on that lathe! In the headstock. In the chuck! I hope they used something other than 7018 or 6013 to weld. That deposits mild steel. Shafts and gears are hardened for a reason. The welding changes the heat treat of the adjacent steel. If it's a typical trucker, he'll go out and load up his truck with as much as it will hold. SNAP. Broken again. Oh, bad luck.
I was thinking the same thing, you. A. See the heat creeping half the way up.
I don’t know anything much about welding , my brother did it for a life time, I did a bit in high school and caught my pants on fire and that was it for me .
The warranty expires when it goes out the door.
I thought " well for chipmunks they're pretty innovative welders"
I agree with you - no respect for the lathe, with carborundum dust everywhere! He didn't need to use an Angle Grinder at all, simply turn the Lathe Tool on its' side, then use the saddle of the lathe to cut a perfect spline. And the repair will never have the strength of a new Unit. But it keeps the Truck working, and earning.
I welded an axel on a Terex Rock Truck , not expecting iy to last that long .I was told to anneal the axel overnight , in a large tube of kitty-litter . or floor dry . It was still cooling in the morning . I thought it would be too soft . I marked it with reference lines . No twisting ,and its still good after 2 years . The break was caused by the dump box rolling over . I welded it with XC 223 Arc Tech . The only thing Id have done different on this guy's job , would have been , to get a similar spline maindrive section , and do the joint away from the splines .
Nice story bro
I've been doing this shit for 65 years. And , this is what I call a perfect job.
as long as they never put the truck in gear and let clutch engage it should last forever haha

Not perfect
I am always impressed with someone who does the best they can with what they have this guy is by any sense the word is a genius and a very creative problem solver. It reminds me of a time when I was a little boy growing up on the ranch and my grandfather would fix things that most people would have just thrown away or repurchased. Even though my grandfather had money he did not waste it. This is a perfect example of why this country is failing and the rest of the world is doing good we can't do anything for ourselves anymore. Most young people if you ask them how about having hamburgers for dinner they would order them on Uber eats.
Total genius 👏
@FullAuto Agree with you for most, but your country (I suppose you meant the USA) is not failing because people aren't creative, throw away reparable things or outrageously consume. China is very successful now and the mid class (up to the upper class) Chinese does consume a lot and discard what doesn't work or is broken. The reason the USA is potentially failing is far more complicated, and partially has a lot to do with... precisely, China. Not in the sense that China is directly responsible for the USA to fail, but rather the USA (politics, industries) has been IRresponsible for using China as their manufacture plant, and letting China go away with IP theft (including theft of military equipments). Americans (and to a lesser extent, citizens from many other countries), have been (ignorantly?) paying China so it can rule half of the world and manufacture weapons that could lead to their destruction.
@@hinokikuaimu you forgot to mention anything about jews, israel, Zionism, jews, jews JEWWWWS
I can't imagine that this repair will last very long. Like other comments have said, when the shaft is under torque and being a hardened steel held together with a softer steel weld doesn't spell out long term success here. Normally this type of fix is most suited to tie the job over till a more proper replacement part is found. Just go easy on the torque in the meantime.
how much do you think this repair cost and how long did it take?

@@winteroutside7014 all grammar nazis go to the video over there ========>

He's obviously going to press a new bearing on there, and who knows, maybe he tempered the whole shaft after pulling the old bearing off (don't know why he would paint it first though). Hopefully there is a welding rod that can match up with the shaft properties for the tempering process. I didn't like the visible runout of the gear end when it was turning on the lathe. Could that be because of the missing bearing race, when in fact the gear and the shaft are perfectly aligned? I would have at least tried to cover the lathe before blowing all of those grindings everywhere. There is hope for that thing. It doesn't appear that he is unskilled, perfectly incompetent, nor totally oblivious to all of the points made in these comments. Would be keen to see a follow up indicating heat treatment, and evaluation after field use.
I hear this guy's been picked up by a major Golf Club company. Because the second this shaft is put under a load, all you'll hear is a LOUD "PING!" Though I must say, the Krylon rattle can tempering was a nice touch.

If if were better welded and with ER312 it will probably hold. Probably will have a sticky clutch due to low hardness of the weld. But with this amount of porosity .. meh
But it will work better than the Chinese original.
My dad was a Machinist, a tool maker he owned J&M tool in Dallas Texas or co-owned I should say, anyway I'm a welder and I really am a damn good welder. I love metal work, what I just seen this guy do, that is amazing to just see it all the way through with what little he had to work with wow much respect!
@@StellarSurge I haven't been watching it a long time I just appreciate the work you did with what he had and that's all there is to it! Why do you feel the need to be up my ass?
@@StellarSurge I am a damn good welder I can weld anything but the crack of dawn and a broken heart! I can lay a textbook stack of Dimes with a MIG welder, I can weld with artistic ability I didn't say anything about his welding I said he did a damn good job it needed to be fixed with relatively few tools he fixed it that's incredible I don't give a shit what you think! I've been to other countries and I've seen what they have to work with and sometimes it's not very much like we do limited cutting tools limited everything so would you get off my ass, you're starting to get on my nerves!
@@StellarSurge go back to your mama's basement and play your little games
If you are a welder you should know that things going snap in a second. would've been better of making a new one out of anything. Any steal would have a better chance of surviving longer than brittle stressed trash he just created lol.
@@StellarSurge That's what I anticipated - a larger, deeper hole in both pieces, a core pin, itself cross pinned to each piece. I'm no machinist, and I'm pretty sure it doesn't count that my Dad was one. The size of the clutch disc (flatter side toward the flywheel, not that it matters for testing) suggests a lot of twist will be put through the shaft, so maybe a welded repair will stand more of that.
Great job! It'll make a great post industrial lamp stand!! I guess you go with what you have.
Would be nice to have an update and take apart of the part so we could see if it is holding up. I think this fix could work if engine power was kept low. Mad Max would be proud!
I bet it lasted two days and snapped again?
100% chance it failed under the first hard acceleration.
He does not care about us. He cares about his customer
I would love to know how this shaft was broken, in over 50 years working as an auto engineer I have never seen a primary shaft with such damage. I can see that the bearing cage was missing so the shaft wasn't supported correctly but has anyone else come across this?. I love the run out on the repaired shaft, if it was fitted to a vehicle it would probably shake the transmission to bits if of course you could overcome the clutch bind. How can anyone say this is good engineering???
"...I have never seen a primary shaft with such damage" It happens frequently to people who drag race their cars. Sticky tires, sticky track, and a (stock) standard transmission is all it takes!

Aaaahm, why did he paint that thing?
@@dirkk.6573 To give the impression that the part is newer and that it wasn't as badly damaged at it seems. This is not fixing stuff, this is dangerous as fuck.
You're completely right. This is not engineering, this is dangerous!
There are at least two rollers missing from the bearing. But he added that much metal back from the grinding sparks, so ok.
😀
If the bearing is missing rollers obviously they are going to replace it, and the video is about the shaft not about the bearing. Smh
@@hectorguzman28 "Obviously"? Not so much. We've seen these guys do really cheap things like reusing transmission oil, smoothing heads with a rock, making really porous welds, making little tack welds, drilling holes freehand, getting sand into everything, and tossing parts down onto the ground. It's not obvious that they're going to fix the bearing.
0:31 I like that arm up on the machine pose after tightening up the Chuck like he just did an amazing feat
Pakistan and Indian men are the greatest makers and craftsmen in the world. No men do more with less than these good men. HONORS to the makers and repair men. 😊
Lots of porosity in the welds that can easily be seen. If virgin metal sheared then metal with a lot of big porosity isn't going to last.
Imagine you are somewhere on a Trans Siberian Highway, and your main shaft snaps in half, you have no means of nipping down to a truck dealer less than a 1000 miles away, and then no means to contact them to rush you a new shaft in the middle of somewhere in Trans Siberian Highway, but a local engineering shop with skilled person is able to rescue you so that the cattle live stock you are carrying in your truck don't die of running out of food, and exposed to ice cold weather for longer than necessary, then it is easier to hike a lift to the nearest town with mechanical repair shop, who can weld that shaft in less than half a day and you can then hitch a lift back to your truck and reassemble the gearbox main shaft and get going again, but this time you ensure that you do not overstress the repaired shaft excessively by not going in higher gears, imagine this happens to you on Moon and the rocket snaps a crucial part, so please remember sometimes you do not have luxury of buying a new shaft, that shaft most probably broke due to a defect in the original casting, and most likely the new weld is even stronger than before.
@@mgabrielle2343 The shaft is certainly not cast. In the case of an emergency repair, it is fine. But I think this is the final repair.
I didn't see no porousness
When you do not have the spare parts that you need, you manage like this. That input shaft will never be as strong as the original.
really really great without any modern machine you are great

It appears to be a successful repair but the question is how long will it last. The original shaft which is designed to take excessive amounts of torque and then now a weak spot has been created. No hardening is a major problem. It looks acceptable though.

I need to know how it fairs in the test of the uncompromising reality, There's no point in all of that no matter how neat and innovative the process is if it snaps in no time.

Much RESPECT for the effort. There is absolutely no way that the repair to this shaft will hold. If you think otherwise Go back to school.
Even added the new product paint at the end to know its done 😊 This guy knows how ro get things done ❤
he didnt up-end the can after using it though
So you have managed to destroy the heat treatment on the splines by welding it, then failed to reharden them after welding. I bet this will snap again as soon as you let the clutch out. Next time don't over load your truck with 10 times it's maximum weight. 😂
Im usually really impressed with these type of videos, but this one, wow. I feel sorry for the poor guy who pulled the broken part out, paid this guy to "fix it", and then put it back in only for it to last as long as Rosie O'Donnell's lunch.
@@williamglendye1692 it's good. It didn't shake the lathe when he turned it on. Machinist 38 years. Lol
Without knowing the emergency that superseded this attempt it is worth pointing out that a shaft failure like this was caused by an eccentric input shaft bearing that lost it's plastic cage a long time ago. The bearing will bind up and cause a high load spike when it grabs. The pilot bearing stub is worn to the point of offering little or no support to the shaft. I would suspect that the transmission front bearing bore is worn out also. But necessity being the mother of invention one must try and not to try you are defeated
yes, if we look closer we see that 2 or 3 rolling elements (rollers) are missing and it will develop an excentric rotation , i think this was the cause from the begining and instead of fixing the cause he's fixing the result and soon will be the same or worse, but i respect trying to be inventive..🙂Also it is worth mentioning that when he induced to the parts so high temperature with cutting and welding, the parts are much weaker in proximity of that place.
No, no, you see that's the genius of it: The worn out roller bearing helps make up for the trashed pilot bushing, allowing the whole friction disk to wander where it wants to without stressing the shaft. 🤣
@@artgoat Ha Ha. why does that sound like the it's practical for a third world country?

The metal is crystalized. No fix will last very long. In many countries you just can’t go out and buy a new part like you can in America!👍

Lovely job, even the clutch plate doesn't fit. You name the mistake, he made it. Think he did just about every wrong engineering practice possible.

Pakistan ... i dont think this was the first time he had seen that particular individual part ... its probably been done and redone ... and re redone ...
I wouldn't be placing any bets on a welded up input shaft lasting long against the torque of a big diesel engine. Especially if it was running on a knackered gearbox input bearing. Bearing in mind though that his circumstances are different than in the UK, I'll give him full marks for effort and also for making a good video.

I love how the guys in the background sound like minions. If one of them said "bananna" I'd have lost my shit 🤣
The best mickey mouse repair job I have ever seen. This repair is much better than the chewing gum & duct tape repair. The shaft is rendered destroyed and useless the moment it broke regardless of the repair afford.
I have done a similar repair to a transfer case output gear shaft, a one piece forging . The difference was that my repair was in a non-splined section of the shaft. After welding we heated the whole shaft with a torch to a red heat then let it cool slowly in dry sand. Next day machined it to dimension then heated it to red heat again, and oil quenched it. Very hard at this point. Heated it in a propane oven to a purple color and let is air cool Reinstalled and ran the vehicle for 200,000 miles with never a problem. The original break that I repaired was unexplained. Happened inside the T-case. Guess it was a defective part.
Probably True , but whatcha gonna do if there's no other option?

May Allah who is the true God of earth Bless this man and everyone in the shop and there family What very highly skilled tradesman
I'm guessing that the bearing missing a roller or three had a lot to do with the failure. The metallurgical composition of this part is now way past questionable with the weld heat localized at the fracture repair point. As metal ages, it crystallizes. This makes it prone to fractures as it is stressed. The shaft doesn't have the strength to withstand the forces that will be imposed upon it.
I have only 3 conclusions here : 1. his labor cost way less expensive than the piece he is reparing. That's why we wouldn't event think about doing it: unprofitable. 2. if the manufactured part broke at first time...this may not resist long, after partial welding, hazardous coaxiality and home-made tooths. 3. the 1:54 made me scream. ...And of course he did the best he could, with this old school machinery, which is still impressive.
Unprofitablable is a relative view. Maybe it was do this job or not eat
It's entirely possible that a new input shaft isn't even available in Pakistan at all. If the truck is old enough, it may not be available anywhere in the world (and might be an insane price if it were-single transmission gears in my 1960's tractors, IF you can find them NOS at all, are many hundreds of dollars.
I like the way all the grit from the grinding wheel went straight into the big roller bearing! I hope he had a spare bearing after that.
That bearing is history anyway - no way it would be used again. Apart from the repair job not lasting very long my concern was where the earth wire for the welder was positioned. It didn't appear to be directly on the shaft so I can only assume it was grounded to the lathe. If that is correct the welding current would have to pass through the lathe shaft bearings and very possibly likely causing damage to them.
I bought a truck originally equiped with a Perkins engine but the previously owner change for a om352. The stock imput shaft is to short for this engine and have to be cutted and welded. Three years ago a have a bad bearing and broke one thoot of the imput gear. I'm buyed another prize and cut the shaft again lol. Two years ago I've changed the engine again, this time is a om366la. The Clark gearbox originally designed to handle with 45kgfm and 145hp is well supporting the 69kgfm and 211hp of this new engine.
Fala-se muito sobre o reparo do eixo. Porém não vi falarem em soldar sobre o barramento do Torno o que deixa o barramento cheio de respingou de solda .
That shows just what can be done when it HAS to be done. Great work.
What is that bearing doing there? With all that dirt inside, it is already fried.
I wouldn't worry to much the roller cage is missing anyway.
The amperage of the welding most likely arced between the inner and outer races to the rollers.
yes, i agree with mr. Randall Dunkley, if we look closer we see that 2 or 3 rolling elements (rollers) are missing and it will develop an excentric rotation , i think this was the cause from the begining and instead of fixing the cause he's fixing the result and soon will be the same or worse, but i respect trying to be inventive..🙂Also it is worth mentioning that when he induced to the parts so high temperature with cutting and welding, the parts are much weaker in proximity of that place.
Me, at the start of the video: 'Great, another precision machining vid' This guy: 'I CAN'T HEAR YOU OVER THE NOISE OF THIS ANGLE GRINDER!'
Assuming that the placing and welding were accurate, this is a temporary repair at best. The force that broke the shaft when it was a solid piece of steel will break it much easier when it's welded, and stick welded for that matter

Input shafts are very difficult to break. I can't imagine the torque it would take to break one. Unless it was involved in an accident. This is something you would do as a last resort. Also, the tools used here are nearly worn out. It takes a certain amount of skill, just to work with tools like that. It's amazing what people can accomplish when driven by pure necessity.
Is something they do when there is no money to buy a new shaft. And the local laws accept this kind of risky procedure.
@@DavidReySilva It took longer to (repair) than it will last. First Journey. FAIL
Difficult to break the first time. Each time it comes back to Abdul’s Plow Works for more oxidized steel, and welding slag inclusions, the torque requirements are lower.
Most likely just for content, they probably broke it on purpose.
I would expect the centre of the clutch disc to wring out before the input shaft would wring off like that
I'm sure it was an emergency repair of a piece that could not be found for replacing. The man made a valiant effort under the circumstances. Like a field surgeon.
Either that or it was just a scrap piece and this was done just to produce content.
Looked like the clutch disc had a slight wobble after he finished, when he was spinning it on the lathe with the clutch disc mounted. However this is great work. People that have to work with what they got can get pretty creative when it's not the easiest thing in the world to source parts. I've noticed on youtube that ppl in Mexico and Australia and Europe, basically anywhere where it's hard to get parts can get very very creative. This is a perfect example although I don't rlly know where he's from lol. Nice work man should work just fine, might have a slight imbalance tho. You could prolly take it to an axle shop or an engine building shop if possible and see what they can do about balancing it. Maybe perhaps shave a little metal here and there in proper locations on the input shaft to better balance it like they do on cams and cranks and whatnot. But that's only if you can even feel some kind of imbalance in shaft, that thing might be perfectly fine lol.
Drilling out both ends and tapping them would save on heat generated, a lot less welding. Temper will surely be an issue long term but i will hand it to em…in a pinch with limit tools and no replacement part capability, something broken down will again move. Agree with other comments on the roller bearing and race regarding spatter and spark. Details matter in quality workmanship. But by the same token -- the customer only gets the amount of quality that they pay for.
Делал такую работу с первичным валом 2101 в начале 80 х. Прошел на нем из Киева в Сочи и обратно и он лопнул. Варил нержавейкой, не помогло.
Нужно было шлици проточить немножко,соосностивидать небыло
Неужели в начале 80х выточить новый вал было проблемой?
@@AtlantDnepr выточить первичный вал КПП !? Вы далеки от техники. Купить было можно, да. Но, как назло в продаже не было от 01. От 03 были, но там другой первичный вал и блок шестерен. А покупать коробку за 310 рублей, это было дорого. За 300-500 семьей десять дней стоил отдых в Сочи. Коммунизм.
They bring it in original shape, but the material properties of a shaft or axle are special and I can't believe this will repaired part has the strength it requires.
I’ve had a similar fix done on my shafts. Difference being that the 2 parts were first pressed together in a press taking 10ton of pressure. Then the chamfered pieced being layer welded in three layers.
But looks 100 times better.
Это не запчасть теперь, это металлолом!
Это не для эксплуатации это для шоу. Я так думаю.
@@user-pl2ue6ds2r шоу начнётся, когда эта хреновина сломается опять пополам в какой нибудь груженой фуре, на крутом и затяжном спуске !
Учитесь, скоро и в России так придётся делать...
@@Mercedes_w211_ Спасибо, но это твоя будущая работа!
В следующем ролике смотрите как при помощи скотча отремонтировать КПП.
This is first grade bodging at its best. Clever approach when you have no alternative.
Just enough to get you to the parts shop to buy a new one
I believe it is spelled botching. IE: I botched the install
@luke s exactly
@luke s I know but to everyone else, hey it looks good it must be good
Be nice to take up a collection and buy him an Electron Beam Welder. Only about 20 million per copy. When Grumman shut down their Bethpage, Long Island main plants--and therefore the F-14 Tomcat Navy fighter production line--a E-Beam welder went for $500 grand! Cheap at twice the price. They used it to weld the wing-box beam structures into the fighters. And then tested wing durability by flexing them to 75 degrees off plane! Never had a failure on those ebeam welded wings--in production test or in carrier service. NICE, NICE MACHINE!
I enjoy watching all your videos you guys Can fix anything
If it ever went back into a gearbox the first time you put your foot down the shaft would twist due to not having the shaft case hardened throughout.
целая заводская деталь не выдержала и лопнула, но после сварки конечно же стала прочнее ))
вал лопается не вдруг. сперва малая трещинка есть, знаю примеры когда такие вареные валы ходили много лет,все зависит от нагрузки.
мОЛОДЕЦ за то что покрасил.Осталось это говно выбросить.
*The Best!👍👏👏👏👏*
Awesome... that extended the life of that input shaft at least 3-4 miles.
Долго смотрел и думал, что чего-то этому буйству мастерства не достаёт... И понял, что не хватает липкого скотча! Нужно им вал обмотать как следует!
Угу, Синяя Изолента решает Все Проблемы!!!😁😆🤣
I would think it would have been as easy or easier just to drill a hole in both pieces and put a little pin in. Then weld. In fact, it might be be stronger to bore both ebds out, perhaps a 16th less than the splines maybe 2 or 3 cm deep, and then make a hardened steel pin a few ten thousandths over and freeze it in dry ice and then put it in one end. Then cool the entire assembly and put the other end in. It will never come apart. Thinking about it. 16th is too thin. You want the walls of the hole you bore to be no less than the thickness of the splines. Otherwise the wall will stretch and deform before the spline. So if the shaft major diameter is say 1-3/4" (its probably metric in fact) and the splines are 3/16", then lets assume the minor diameter is 1-3/8. Figure 1/4 wall thickness is a reasonable guess of what you need so the splines don't deform or break off or crack. Then you bore and ream a 7/8 hole and then put a pin a thousandth or three over on dry ice. Then press in place. Then make a jig to hold the thing , chill it down, get it mounted up and indexed correctly and press it together. If you get it right, then the crack will meet up right and then the pin will expand and it will never come apart unless you cut it. If you use a?suitable piece of hardened steel of a suitably strong alloy , it should hold. However, a REAL fix, would be to cop the shaft off the part at the end. Find a hardened steel shaft like maybe an axle shaft with the same splines if you can. If not make one. Then bore the gear end out and shrink your shaft in. That will make a permanent repair. Some people might feel good pining it but if you shrink one part in dry ice, heat the other to 350F in an oven then press them together, they are never coming apart. So long as that pin can handle the torque it will work. The problem i see with the welded repair is two fold. The metal will be annealed in the heat affected zone. Since it broke once when the part was at full strength, it WILL fail now that its softer. 2, I'm concerned that the filler may just be a mild steel. So it's an open question if the weld will fail or the metal adjacent to it in HAZ. (Thats why i suggested that a pin may be better. At least if a 7/8 oin can be made from a sufficiently strong material, its good hardened steel). The best solution as i mentioned, replaces the entire shaft. In that way, the shaft grips the gear at its outside diameter and all of the heat issues are gone because you made or found a new shaft. If your licky, you might even find. Shaft sitting around.
This is good idea💡
Been over 30 years since I took Mechanics of Materials in College, but people that weld. Wouldn’t the original pieces at the welds be brittle with all the heat and no quenching? I never got deep into welding, wish I did.

Мне интересно через сколько километров этот вал сломался? Вы ведь термическую обработку не сделали.
Разный металл, разная и не однородная структура металла, отсутствие закалки. Долго не протянет под нагрузкой 100%. Из говна и палок что-то сделали. Похоже на то чтобы доехать или дотянуть куда-то.
Rapaz vocês estão de parabéns viu vocês são muito profissionais parabéns mesmo
Аслт
Parabéns 🎉🥳👏 vocês Realmente faz acontecer vocês são top 10 👋👍
Good video. As an engineer, if you have any doubts, please let me know. I will try my best to help you solve them
this would only ever be acceptable if you were in the field and somehow had a lathe and welder at your disposal. You can easily see that the diameter of the shaft has been reduced where the repair was done. Also curious as to how accurate the "metal twig" dial indicator is :)
the metal sprig, it's an old school classic... and it's worked great so far, obviously you're not in the business.
@@paulosouza3369 lol, I have an actual dial indicator, you can stick to your 3rd world accuracy and keep using your sprig bud.
@@1114flibby "It´s old school" just like the lathe the guy is using. If you don't get it, kid, it´s no surprise.
@@paulosouza3369 kid????, that is f'n hilarious :) if you were my age you would be retired from the military long ago.
The "field" you speak of is called the middle east, it's like being stuck in a infinite cycle of surviving with what you have
Na verdade a árvore primária da caixa de câmbio não faz tanta força, quando se adapta motores em outros tipos de câmbio por exemplo motor Mercedes em câmbio Clark ou Eaton se emenda o eixo primario.se este sofrer torção fica por conta da caixa de molas disco de embreagem .na minha opinião ele apenas tinha que ter feito um chanfrado maior para receber mais solda,ou arrumar outro eixo para emendar fora das estrias. O eletrodo usado é o 7018

Man, i love seeing all the experts talking in the comment section.
10 SECONDS after you let the clutch up CLUNK CLUNK BANG.
All that grind spatter in the roller bearing that will be a real pain to get it clean, which I very much doubt will happen. I would question the torque load the repair will take. Notice that the shaft was only centred in the chuck with a pointer that was supported in a stand resting on a flat(?) board, I doubt the shaft was concentric.
Good good good good vibrations?
Guess that bearing missing rollers and all that new welding spatter grit in the race doesn't matter all that much since the entire shaft probably sheered again once the clutch engaged.
Oh no worry, the structural rattle can paint will at least double the shaft strength and seriously reduce the bearing noise.
In the positive side, the machinist will learn that this fixing isn't working.
All you machinist out there…..you are the true hero’s of the mechanical world….what you can make, fix, modify, create is insanely cool.
You're absolutely correct. That's not what you watched here though. This should not have been "fixed" and will fail again almost immediately. A good engineer and mechanic should know when to say no.
I see quite a lot of imperfections in the welding, where new crack will form easily. With the paint you can cover all these imperfections, but it won't make the joint stronger. But of course if you have no means to buy a new shaft, reparing is the only solution. I suppose there are no used spareparts available. It is by no means a genious job, because every skilled metal worker can do this.
¶№9986
actually i think the paint was used for part fitment as a abrasion indicator of areas that needed further grinding and to prevent rust
The paint is the only thing making it strong... those welds are not.
Можно с разбора бу найти.
Facile criticare, certo che in Europa un lavoro così non lo farebbe nessuno, in quanto non puo' dare garanzie, ma in un paese dove non c'è nulla e' da ammirare la volonta' e la capacità di queste persone che con nulla risolvono il problema, anche se in maniera qualitativamente inferiore ai paesi sviluppati! Questi video li fanno per farci vedere e conoscere la loro arte di arrangiarsi e vivere in un mondo enormemente arretrato rispetto al nostro! Costoro previa adeguata preparazione, se fossero introdotti nel nostro mondo sarebbero degli ottimi operai! Il problema che qua emigrano quelli buoni completamente a nulla, e voglia di fare nulla, che anche con la adeguata preparazione....
