The top gear which was broke due to overload was very well attached - ยานยนต์และพาหนะ
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.
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.
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
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.
Artistry. Impressive.
@@rafars2246 he has 45 yes of experience on this and u have none and I am also an engineer
as long as they never put the truck in gear and let clutch engage it should last forever haha
Drag racers in the 60's welded camshafts and ground them down to get the lift and duration they wanted, chet herbert was really good at it
This is wrong on so many levels... 😱
Well it's true haha@@ronaldschoolcraft8654
@@SouthMainAutoI meant the hack repair...
Not perfect
Гениально! Из измерительного инструмента только линейка и ответная деталь. Нарезка шлицов отрезным кругом. Сварка высокого качества. Отсутствие термической обработки. Я в восторге! Надеюсь эта высокотехнологичная деталь будет использоваться в качестве якоря в лодке, а не в трансмиссии.
одноразовая приблуда . как всё у них сделанное на коленке
На таком станке,где скорости меняются перекидыванием ремня вручную и все операции делаются резьбовым резцом,хорошо получается шлицевая болванка...
Ещё и подшипник не отмыли после болгарки.
Главное покраска, если не красить не будет работать)))

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
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.
В этом видео прекрасно все. И резьбовой резец по всем операциям, особенно центровка сверла, и капли расплавленного металла от сварки в подшипник в купе с отходами болгарки, и работа машинкой по пазам. Спасибо вам Биба и Боба, вы сделали мой день.

Ну если у тебя нет альтернативы, то это лучший способ ремонта.
а еше соосность двух деталей при сварке.
Это ролик о том как нельзя делать)
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.
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.
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.
This guy will repair this particular piece every single day.
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.
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!
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.
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.
Knnomi
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.
really really great without any modern machine you are great
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.
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!
Amen
Agreed!
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 :)
Excellent Job on the repair Highly Skilled Machinist Thank You
Lathe ways and roller bearings need occasional welding spatter and grinder dust to function properly.
Jeez, I thought deep sarcasm was moderately dead.
I love 💕 the spline cleaning!
You does with what you has!!
I've seen yous does better! Maybe aknew dirtshop?
Alright hogji.
Welding on a lathe machine 😬.
Stray currents through the bearings 😔.
Pre heat & heat treatment 🤔
Great job! It'll make a great post industrial lamp stand!! I guess you go with what you have.
I enjoy watching all your videos you guys Can fix anything
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
Сварить лопнувший вал-Это последнее,что мне пришло бы в голову)Хотя и в этом не уверен.
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
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.
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.
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.
The paint job was the crowning touch!
You can't polish a turd, but you can put glitter on it.
And sold as new on ebay
Trabalhoso , será que vai aguentar depois de montado ?
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. 😊
I've been doing this shit for 65 years. And , this is what I call a perfect job.
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
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.

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!
Fantastic fab and welding skills!
"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.
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?

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
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.
Considering where he is and what he has to work with, I'd say 'damn fine job'
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 ...
Use what you have! Well done Sir!
magnificent job, bravo.
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.
May be few months.

@@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.
Mashallah bhai bhot Wadia 🌹❤️
Wow... !!! My best friend, Wonderful upload! Keep it up! +thumb up3!
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.
I will say, these guys fix a lot of stuff with what they have. I'll give them that
I agree, and do give them credit for that. They have to come up with ideas to fix gear, with only basic tools and equipment, and I'd guess a serious lack of knowledge/training. Would we do as good ??
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.

These guys are amazing!
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.

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.

The topper was when he was grinding and throwing it all into the main input shaft bearing.
These people are so clever just amazing work and no union here ch
Nice ...good job...very informative like mine😊👍
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.
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. 🤣

He does not care about us. He cares about his customer
Whatever the job if the focus of the results amazing👍
Man, i love seeing all the experts talking in the comment section.
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.
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!
Good.. Job.. 👍🏾👍🏾👍🏾.
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.
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?
