@@classicmoto2429 Well thanks for your input, but being a heavy duty mechanic and welder, for 4o years, and certified in both trades, my best guess is it may look good, but it will have no durability. If it makes you get out of a muck hole on the farm, then it would have some benifit.
@@nilos21k it is probably a cast iron pinion. Cast iron has a high enough graphite content that it essentially self lubricates as you cut it. A lot of the maching I do on cast iron cylinder heads is done dry for this reason. When a coolant or cutting lubricant is used, it sometimes makes it harder to cut it. The only downside to using nothing is you should definitely wear a respirator or dust mask, you do not want to breath in that cast iron dust.
It is painful to watch for Machinist, welders , mechanics and the engineer that designed it . Welding with it on an unprotected lathe was bad but the grinding process even worse. I doubt it broke when they torqued the pinion nut because they don't torque any thing. In that part of the world if it looks like it is fixed it is good enough. Lives are very cheap.

As bad as this probably is, still have to respect the time and effort these mechanics put into repairs. It’s definitely not the right way. But probably on that side of the world it’s *the* option they have to take.
3:17 Look at the amazing rigidity of the lathe. It looks it have incredible precision of at least ±1 mm or even more. The machine matches the technology perfectly.
I don't think runout will be a problem. The taper that squares the yoke up was on the "good" side. As far as the splines go, they were already toast so it doesn't hurt to try. I repaired a blow out in between cylinders on an engine block of a turbo car with a nickel rod, a 4 1/2" grinder and a utility blade as a straight edge while it was still in the car. People were protesting so loudly that you would have thought I was killing puppies. It worked out great. You roll the dice and sometimes you hit your number.

I'd love to see a follow up on how long this lasted... Maybe the driver just needed to get back home to a proper spare part, like the captain that flew a 747 from the USA back to Heathrow UK with a blown engine because the US workshops wanted too much to replace it. A bit sketchy setting off on 3 engines across the Atlantic on purpose, the busted Rolls Royce engine was testing how long an engine would last on the 747 before failure, more than 36,000 hours without overhaul which is quite impressive. I've welded a few forged steel parts by preheating and laying down some root welds with a domestic 120amp MIG and they're still working 25 years later! I once did a temporary fix on a diesel injection pump piston by gluing with JB Weld, the guide block back onto it, while I waited for a new one. That was in 1992 and it's still working, god only knows how as it hammers up and down and gets quite hot in service, which I would have thought would melt the glue. Sometimes rough repairs can work, other times not!

Nicely done... predetermined breaking point. But it is not fair to judge from our part of the world. They probably have to do it more often for lack of spare parts (and money). I would also be interested to know how long it lasts.

No OSHA, no problem. There are 100 or more waiting for his demise to give it a try. Then they will migrate here selling themselves as highly skill machinists willing to work for one-tenth of what American, well trained machinists command in compensation.

Get used to this solution because in today's world, reputable manufacturing has fallen of (thanks bean counters) and replaced with just in time mass production as cheap as possible.
Given what the machinist had to work with and perhaps unavailability of finding a new part, it looks like he did a pretty good job repairing the pinion. However, the proof will be in the pudding on how long it lasts and whether there are some alignment issues that break the part again.
You have to work with what you have!

No stress risers in that "repair". And excellent heat treatment after the "repair". I'm beginning to think these videos are just an elaborate joke being pulled on the rest of the world.
I have the same doubt as you . Maybe the truck will run fine until it goes up a hill ? If I was stranded and there was no other option I would try this , If it breaks it might take the driveshaft with it ! I would like to know if the repair is still in service ?
The method of welding it back together can work. The problem is you need much different welding techniques and specific materials. Their equipment was really in poor condition and they didn't weld it properly. Then he just fucked the piece with the grinder. Should have been on a mill for that. pinions are very important and can't have any play in them. He'd be lucky if he made it a mile with that in his truck.
When I clicked on this video, I was hoping it'd be something out of the ordinary with the strength to match. Beautiful...maybe...good enough...if you use it for the battery powered cars for kids, I reckon it'll last forever 😄
Welding on the lathe will weld the bearings on the lathe. I had a farmer welding parts on his tractor out in the field and found out later he had bearings welded to each other.
I would say at maximum it has 10% of its original strength getting less and less as used due to runout. If the truck was emptied and only required it to get back to base it may work if driven gently. When you are stuck in the middle of nowhere then something is better than nothing.
@@MrMaxeemum Nowhere did I insult those fellows work, they are in a Country that has very little concern for the individual. My statement was concerning their government, please don't try to read between the lines.
I'm very interested to know how long the repair has lasted . And what rod was used. I wonder how the heat affected the tempering ? And was it induction hardened ?
@@MrHitchikerOz then in your opinion it's not even good enough for a emergency repair . I've welded drive shafts that worked great and had no issues , but it's not really comparing apples for apples .
When they will start TIG welding on those repairs. There is so much integration of deposits in this weld that may survive going out from the parking area. And how expensive are center drills?
That wasn't anything close to tig welding. They where stick welding which dumped a ton of heat onto the part. It will snap off again in the same place.
They had welded wheel axle shafts (even higher torsion loads) before so this repair is no big deal :) In the next video, they will weld a broken conrod...
@@jacobclark89 Who knows, maybe the original failure happened because the part was too brittle. If it runs true the repair might be stronger - IF it runs true.
Its not a matter of "probably", its definitely going to break the first time any torque is applied to the driveline. They spent alot of time repairing a paper weight.i certainly wouldn't use that pinion in anything i own.
I wish they had shown the installation of the repaired part. Watching them set the pinion preload and checking the mating of the gears to the crown wheel would have been entertaining.
I seriously doubt they go through that much trouble, the truck that is for is not meant to last due to the nature of the roads they tend to drive on. Wooden body on a cheap metal frame.
Yeah this is BS there's 3 possibilities here either they are really, really stupid. They are getting ready to fk someone selling the truck. Or this is just for the video.
I think the problem is their steel. You see how easy that drill bit went in there? Have you ever tried to drill a pinion shaft? It doesn't happen like that.
Обороты на металле - огонь, резцы либо тупые, либо из мягкого железа, но болгарка вообще добила, хотя если посмотреть на его мастерскую, за неимением инструмента вполне сойдёт и болгарка. Токарю не хватает знаний металлообработки и инструмента, но он молодец.
Apparently they are proud of that kind of butchery. My personal opinion, that's a lot of work just for a paper weight. I wouldn't let that pinion get within 100 miles of any of my vehicles.
Most of the comments seem to think that the weld won't hold , but in reality not all of the people who commented are welders and out of the ones that are, probably only a small percentage are expert at welding cast , so I feel that the majority aren't quilafied to make the assessment in the first place , I do see a trail of mistakes made while making the repair that makes me loose trust , but I must give respect for complexity of the repair . Im sure they make many repairs that have been a great help to society and deserve respect for that . When it comes to welding, their are many different processes and disciplines to master . Boilmakers , jewelery welders ,under water welders ECT.
Probably doesn't matter if the splined shaft winds up slightly shorter since they probably use shims to fit the gears together. Main thing is to maintain the two welded parts are parallel. I suggest safety glasses, even though nature gave us a spare eye. Interesting how they make a grinder work since presumably don't have a horizontal milling machine and correct cutting tool for the splines. Cost of repair $15? Biggest concern is if this is the input pinion on the differential of a semi-truck, as they must use engine-braking to control downhill speed. If it snaps, the truck could runaway on a steep road.
@@dementedbowine8681 Did it set up correctly? good gear mesh and backlash? Runout within tolerance? Pull a load without breaking for more than 10 days?

And of course we know what happens when you weld previously heat treated steel, yes it will crack across the weld. Dodgy Bros. at work.
Would it be better of the heat treated it after the weld?
It's been repaired 3 times this week
When I clicked on this video, I was hoping it'd be something out of the ordinary with the strength to match. Beautiful...maybe...good enough...if you use it for the battery powered cars for kids, I reckon it'll last forever 😄
Welding on the lathe will weld the bearings on the lathe. I had a farmer welding parts on his tractor out in the field and found out later he had bearings welded to each other.
this only happens if the current passes trough the bearings, if you put the clamp on the same side as you are welding this is not a problem
That's funny... That machine is probably older than you and me... Probably not a day that goes by that they aren't welding on it...
one thing for sure, a metal lathe like that can build a lot of wonderful gear. thanks for the video
I would say at maximum it has 10% of its original strength getting less and less as used due to runout. If the truck was emptied and only required it to get back to base it may work if driven gently. When you are stuck in the middle of nowhere then something is better than nothing.
That and the instant annealing from the welding. Any hardening that spline or gear had is toast.
The entire country is nowhere!
@@cat637d That's a bit unfair, These guys did good work with what they had and there are places that can easily beat China for quality.
@@MrMaxeemum Nowhere did I insult those fellows work, they are in a Country that has very little concern for the individual. My statement was concerning their government, please don't try to read between the lines.

I'm very interested to know how long the repair has lasted . And what rod was used. I wonder how the heat affected the tempering ? And was it induction hardened ?
Lasts longer than having no pinion gear
I'd give it 10 turns of the back wheels.
@@MrHitchikerOz then in your opinion it's not even good enough for a emergency repair . I've welded drive shafts that worked great and had no issues , but it's not really comparing apples for apples .
They offer 30 30 warranty .. 30 seconds or 30 feet
Hardening and tempering are inventions of the devil and should be avoided
at all cost....
You should never repair one of these, they are made of high carbon steel
I guess you work with what you've got. I would lose my job if even suggested a repair like this.
Интересно а лопасти турбины самолета он тоже сможет приварить
When they will start TIG welding on those repairs. There is so much integration of deposits in this weld that may survive going out from the parking area. And how expensive are center drills?
That wasn't anything close to tig welding. They where stick welding which dumped a ton of heat onto the part. It will snap off again in the same place.
As other viewers mentioned be very careful you're clothing doesn't get caught up in the machinery . That's a major cause for industrial accidents .
so what happens to machinist that are careless.... they don't make it
@@Dogleg1957 maybe if it is a very large lathe .
Who doesn't love a dry high speed and feed interrupted cut into case hardened steel with no coolant...
You don't repair anymore, you throw away and get a new one it broke for a reason
Good job 👍
By the way you truly master Jawa, very fluid.
They had welded wheel axle shafts (even higher torsion loads) before so this repair is no big deal :) In the next video, they will weld a broken conrod...
I am fm pakistan , in fact they do weld conrods
Do you if the repair has lasted ? I'm wondering about the heat from welding taking the tempering out .
@@jacobclark89 Who knows, maybe the original failure happened because the part was too brittle. If it runs true the repair might be stronger - IF it runs true.
I could have done the same with JB weld, it might last longer too.
У них свой мир - Нирваны !
Amazing.
The most 'Beautiful Way' about this video is the laughs I'm getting reading the comments.
Curious to know what kind of vehicle or machine the pinion went to and if this repair held up. Making do with what you have and getting the job done.
nice sandals bro!
that welding it's hard enough like to use spitt . good job.
EXCELENTE RECUPERACION DEL PIÑON. UN SALUDO A TODOS AQUELLOS QUE SE DEDICAN A ESTA NOBLE LABOR. ATTE. MOY.
Who needs a mill, when you've got a good grinder. Jeez!
The end result is the shaft out of center and the weld will not last. the shaft will probably break again. Seriously a beautiful Job?
Its not a matter of "probably", its definitely going to break the first time any torque is applied to the driveline. They spent alot of time repairing a paper weight.i certainly wouldn't use that pinion in anything i own.
I cannot see that being strong ENOUGH
Electrodos 600, se usan en ARGENTINA
I wish they had shown the installation of the repaired part. Watching them set the pinion preload and checking the mating of the gears to the crown wheel would have been entertaining.
I seriously doubt they go through that much trouble, the truck that is for is not meant to last due to the nature of the roads they tend to drive on. Wooden body on a cheap metal frame.
I admire the skills of these people,what an ingenuity
I wonder if it will hold up or just break again when in use, But good idea.
I wonder how the heat from the peck welds is going to help the temper of the metal? Maybe a little brittle .
Just enjoy the proces, i like to say" what a great proces
what welding rod you use?
You know these guys are doing this video just for the clicks. As soon as they were done filming, they threw the part away.
Or if it lasts just long enough to sell the vehicle
HAhAha😂😂😂
Yeah this is BS there's 3 possibilities here
either they are really, really stupid.
They are getting ready to fk someone selling the truck.
Or this is just for the video.
I think the problem is their steel. You see how easy that drill bit went in there? Have you ever tried to drill a pinion shaft? It doesn't happen like that.
@@alexduke5402 did you see how hot the metal was when machining ? Did you hear the sound it was making ? It's got some hardness to it.
Я так понимаю этот токарь не слышал про стружкоотводящую конавку и подбор оборотов. Но как он сверлил я был в шоке.
Обороты на металле - огонь, резцы либо тупые, либо из мягкого железа, но болгарка вообще добила, хотя если посмотреть на его мастерскую, за неимением инструмента вполне сойдёт и болгарка.
Токарю не хватает знаний металлообработки и инструмента, но он молодец.
у них и изоленты нет, что бы намотать на резьбу, видимо - да расстроили меня ребята
@@rubinroterstern молодец в чем? Эта деталь работать не будет.
@@zmagarbel что он хотя бы попытался что-то сделать без знаний и инструмента, потому молодец.
В будущем или поднимет качество, или уйдет из профессии.
@@rubinroterstern чтобы поднять качество - нужны инструменты, а для этого - инвестиции. С такой работой он нихрена не заработает.
Good idea
You just know that when a heavy component was dropped on the floor,nobody ever said,thank God I was wearing sandals.
Those are Chinese safety shoes
its a good video to learn how repair will be not done.
Hard to believe that they are proud to show off this degree of butchery
Apparently they are proud of that kind of butchery. My personal opinion, that's a lot of work just for a paper weight. I wouldn't let that pinion get within 100 miles of any of my vehicles.

Muito bom Campina
Most of the comments seem to think that the weld won't hold , but in reality not all of the people who commented are welders and out of the ones that are, probably only a small percentage are expert at welding cast , so I feel that the majority aren't quilafied to make the assessment in the first place , I do see a trail of mistakes made while making the repair that makes me loose trust , but I must give respect for complexity of the repair . Im sure they make many repairs that have been a great help to society and deserve respect for that . When it comes to welding, their are many different processes and disciplines to master . Boilmakers , jewelery welders ,under water welders ECT.
I bet that is a hell of a good weld.
Ray Charles made better welds. Your tail stock is off so bad, you need curved drill bits!
🤣😂 I give it a 60/40 to break in the first month. And a 40% it will take out the drive shaft when it breaks.
Probably doesn't matter if the splined shaft winds up slightly shorter since they probably use shims to fit the gears together. Main thing is to maintain the two welded parts are parallel. I suggest safety glasses, even though nature gave us a spare eye. Interesting how they make a grinder work since presumably don't have a horizontal milling machine and correct cutting tool for the splines. Cost of repair $15? Biggest concern is if this is the input pinion on the differential of a semi-truck, as they must use engine-braking to control downhill speed. If it snaps, the truck could runaway on a steep road.

It’ll make the trip down hill. But that truck with that part will never make it uphill to complain.
I wonder how long the warranty is?
THANKIOU
if you know what run out means as well as fits and tolerances this is nightmare fuel just for you.
this is the dirt cheap fuck it good fix
@@dementedbowine8681 Did it set up correctly? good gear mesh and backlash? Runout within tolerance? Pull a load without breaking for more than 10 days?
Which type of steel rods would be needed.
what modul have the griding wheel omg that was unaspekable 4 meters only to break again
If it broke the first time, what makes you think it will last now?
They sound like chipmunks on ff i was waiting for dave to yell alvin lol
