Massive Repair on BROKEN - Crankshaft & Bearings | Gouging & Welding | Manufacturing & restoration 

I love seeing a pristine bearing being rolled around in the dirt

I can't believe that they did not use an ounce of lubricant when replacing those huge wheels. Everything I have ever done involving an axle and a keyway, oil, or grease always helped.

The guy holding the bar to be hit by the sledge is incredibly trusting.

I wonder how they decide who gets squashed next. Flames and sparks everywhere and blokes in dresses, what could possibly go wrong 😂

I'm glad he has his safety squint on when cutting..

This situation is a perfect illustration for the old saw: Perfect is the enemy of Done... Sure, it's something of a horror show if you're used to clean-room assembly facilities, but this is reality in many parts of the world.

Mmm hammered bearings. And hammered cast iron flywheels. And blowtorched axle! All the things we love and approve here in 1930s USSR!

Other than most commenters here I have respect for these men that get the job done with elementary means. I wondered if it would have worked if they had tried to pull the two wheels towards each other doing the following: 1) Place both wheels on the axle, keys in place. 2) There are 4 holes in each. Feed a chain through the two opposing uppermost holes. Do the same with the two lower holes. Close both chains into a tight loop. Stick a bar through each loop and have a man at each wind the loop so it tightens. And another idea: the center of such an axle contributes next to nothing to it’s strength. A throughhole could serve to poor in liquid nitrogen to shrink it and ease disassembly. Your comments are welcome!

They are getting the job done, and very resourceful too! It always amazes me how these guys are able to work with what little they have and succeeded 💯👍👍

I like and respect the low-tech sheer force basic tools they have to employ in Pakistan (?) To replace two beautiful steel bearings(unpacked& un greased) barely out of the dirt to parts that are bare wiped clean and re assembled is like putting nice lipstick on a pig.

Not exactly precision work but these guys deserve every penny they earn.

These guys know just the right amount of magic dirt to pack into the bearings for proper break in.

Third world hero’s. Amazing watching how much they can do with very little.

All that personal safety gear used is outstanding

These guys are strictly bush leaguers. I worked on rock crushing equipment for a couple of years and replaced dozens of these live jaw bearings. This assembly is from a rock breaker which breaks larger rocks down to a size that will feed through your crusher. These things weigh a couple of tons so you should use nylon slings or a chain sling instead of a decking chain and make sure your rigging is properly placed so you don't drop the unit like these guys did. To remove those flywheels you set the unit down flat on some dunnage so their outer edge just clears the ground. You use a 50 - 100 ton hydraulic wheel puller rigged through the holes in the flywheel with a pulling bar so the hydraulic ram applies pressure to the end of the shaft. I know a lot of you are going to say that they don't have a hydraulic puller because they cost too much. So how much would one cost in comparison to having a backhoe with a jackhammer unit? The answer is less than 5% so that is no excuse. Once you have your puller in place you crank up the ram pressure and many times the wheel will pop right off. Sometimes you have to shock the wheel with a sledge hammer by hitting it on the wheels face. On occasion, you may have to apply a little heat with a tiger torch to the wheel hub to get it to break loose. The wheels are a taper fit on the shaft so once they move a tiny bit they break loose easily. When it comes to the bearing replacement, you start by splitting the outer race with a cutting torch and then cut the bearing cage apart leaving you with just the inner race. To remove the inner race you can use a hydraulic puller with a bearing splitter of an appropriate size or you can use a cutting torch. If you use a torch YOU DON'T USE IT LIKE THESE GUYS DID. Instead of cutting perpendicular to the shaft, you lay your torch over so it is parallel to the shaft. Going perpendicular can and will damage the shaft like they did here at 14:29 where you can clearly see the gouge taken out of the shaft which weakens it and may cause it to fail in service. With your torch parallel to the shafts surface, you start to whittle away the bearing using just enough oxygen cutting jet to blow the oxidized metal out of the way. When you get down close to the shaft you can see the line of departure between the bearing and the shaft. Keep working at it until you have cut all the way across the inner race. There is no need to cut more than one slot! Once done, you take a cold chisel or a steel wedge and place it parallel to the shaft surface and drive it into the end of the slot you just cut in the race. The wedge effect will cause the race bore to open up and you can easily slide the race off the shaft. When you install the bearing and the flywheels you should always give the mating surfaces a coat of anti seize. This will keep the components from freezing together should they have to be removed in the future.

Yes, just the environment for a precision bearing.That's the way to mount a bearing, just use a bigger hammer.

No one could have possibly seen that lifting lug failure coming.😂 6:42

This is awesome work carried out under a shed ? This should be done in a heavy machine workshop....but this teams looks so clever and and done the job in a small shed...hats off.

I'm a design engineer, I learn a lot from these videos, thank you!

Ahhhh! All done, good for another twenty hours of work!?

They are installing new bearing and don't bother to cover to protect the bearing from dirt, moisture WHAT A BUNCH OF HACKS

I think the Health & Safety manager was away that day.

Yep, I always wear explosive cotton dresses when I'm torching it up. 😂😂😂

When I see these type videos, I always wonder how many don't go home after work and/or go home with major injuries...

I'm always amazed by their ppe😮. I really feel for the guys in sandles.😢

Just gotta love those steel capped Sandals those guys use. There must be a market in the West for that kind of thing. Well done for your safety team.

That temporary lifting bracket failing was almost a given. Even the welder looked nervous about it when they first lifted with it. Presume that's a rock crusher Jaw and elliptical axle assembly?

How do they keep from catcking on fire, they'r walking wicks.

Cleaning the area where that lug went on would be my first priority. Weld would have some good metal to bite into

So what do you prefer today? Getting crushed to death or getting caught on fire?

Use a tag line guys on stuff when its on that crane. Helps guide it as well as if you keep a bit of tension on it. You can feel if its going south a bit

I can only imagine the HR department at the end of every day deciding how many replacements they will need to hire due to injuries

How about those steeled toed sandals? It appears that a large part of the safety program consist of the guy in charge of safety shouting ," look out , get out of the way " before one of the men is crushed by the crane operator .

ما شاء الله تبارك الرحمن - ربي يحفظكم ويبارك فيكم - عمل رائع

My favorite tool for taking off stuck pulleys and bush bores is an air hammer, so I completely understand the way they removed those, but they needed some sandpaper, emory cloth or something to clean up those surfaces before replacing them. Then they should have added some anti-seize and some grease or oil on the threads. The next time those bearings need to be replaced, they might end up with the shaft getting pulled out of the housing before the pulley and flywheel come off.

Necessity is the mother of invention...old school still works....pity they couldn't have rolled the bearing over some wood but at least it was still in its protective wrapping...keeps everyone fed...👍👍

Got to love those Indians. They have absolutely no fear of anything. I guess when one dies a thousand more are there to take their place.

I’m a sally safety guy, given the conditions, they are amazing. It’s the cultural attitude. It is what it is.

Gute Arbeit in Badschlappen. Wenn der Fuss mal platt ist, steht schon der nächste bereit.

When I nod my head, you hit it!

not pretty, but job got done. thanks for sharing!

when i see this i allways think, safety first!!!!!

mohamed your project IS ON FIRE!!!

It is the moveable jaw of a rock Jaw Crusher, the part of the shaft through the casting is elliptical

Did I miss seeing packing the bearing with grease

YES the Safety Gear, sandals & loose clothing, then the lack off gloves, safety glasses, face shield, burning goggles and welding hood. Maimed, blind and deaf at an early age. Very sad....

Not quite up to the safety standards i've been use to , but they got the job done in the end .

It's impressive to see how resourceful these guys are in getting the job done, especially given the limited tools and resources they have available. It's a testament to their ingenuity and determination to succeed. However, I can't help but wonder if using an excavator to hammer open a container was really the safest or most efficient option. It's important to prioritize safety and consider all alternatives before resorting to drastic measures. Nevertheless, it's interesting to see how they were able to ultimately get the container open, and I hope they were able to achieve their goals. 💯👍👍

Love the safety sandals. Looks like Brampton...

These guys a amazing.

Got to admire the safety shoes and eye protection. That chisel should be entered for the world record mushroom growing competition. First bearing walked on so was not even an interference fit on the shaft and the second bearing was hammered on whilst still being held by the hoist, both will lead to premature failure of what will be a very expensive bearing due to incompetent fitting.

How about the sledge hammer to the bearing ? Ruined it, dented and dinged , unbelievable 😮

Imagine standing next to that machine (whatever it is) a getting it up to speed !??! Knowing that those bearings were rolled around in the dirt , no degreaser to clean the shafts, no grease on the bearings! Its like a time bomb!

Bet them blokes knew they were swinging that thor hammer all that time lol

Had to laugh when the 'lifting eye' stuck on by the 'welder' gave way.. zero surface prep, probably little weld penetration and the eye was made out of some scrap from the last job and stuck on with bird poo weld.....

What a hack job, cleanliness be damned and the keyway for the counterweight were shot. They will be revisiting this in the not to distant future.

Used oil goes on the floor to keep the dust down

This is my type of vid.. Ta for uploading 🏴󠁧󠁢󠁳󠁣󠁴󠁿👍

Look, I'm no engineer, but it seems to me this situation clearly calls for the application of inverse reactive current, stabilized across a unilateral phase deflector, which could automatically synchronize cardinal values using a calibrated set of variable dimension flux wrenches. No, I'm not talking about common variable dimension flux wrenches you'd use in a modi-fisable application; that would almost certainly yield a reaction of magneto-relative gyration which would spin around at something like (X = the scalic ratio) x (times) (rotational corona ÷ π) - (minus) E .... or, if my "off the top of my head" calculations are correct, at somewhere around 4km per second / per second! Whee! (That's just a guess, of course. The exact diameter of each of those wheels, disks, gears, flanges and shafts would have to be computed taking into account the potential acceleration of capacitive duractance before an accurate measure of umbilical radiation could be made.) Also, it sure wouldn't hurt if they had a few liters of prefabulated amulite - suspended in a solution of dynametric spall of course - which could be applied by a hydrocoptic marzel tube, thus reducing the ambificient resistance to a negligible number. That would likely yield best results if rectificated by using the Maynard-Kroll Longitudinal Cam Sluicing Procedure, of which I'm sure you're all familiar. (By the way, it was the young American physicist Kroll - his first name now lost to the ages - who initially applied a dilentium voltage across the special temporary clamps attached to the derrieres of over 600 particularly fulsome female volunteer test subjects, all of them student volunteers from hair style salons in China, Japan, Norway, Sweden and New Jersey. Now, I'll just bet 2 or 3 of you are thinking: What about the effect of logarithmic spurling when side felminescence takes over? Great question! In my experience, the cellular degradation of substances like tempered steel with a hardness MOH of 4.3 or less, will allow deltoid panandermic fusions to be minimized... thus cancelling subsequent fuseal modalities. I'm sure the fellows in the video considered - then dismissed (and rightly so) - the use of a drawn sinusoidal trennion. That could have applied considerable force during the early cabulation phase of their effort... but it would also have induced an unacceptable level of bi-thermal scoring on the helio-multimetric shaft... something none of us wants to see, right?! Simple really.

If you want that thing off the shaft then why is it on the ground where it can’t fall?

Nice looking roller bearings. From Sweden. This must be some serious gear :)

Quality work .if the elephant would help

I wonder if they ever watched Shake Hands With Danger movie series.

I wanna hear the guy holding the steel chisel scream when the guy swinging the sledge hammer misses and hits the chisel holder in both arms - and we hear the bones snap.

Appalling working conditions, however It's good to see they are at least wearing their safety flip-flops.

What is this piece of equipment? Pump or some type of hammer for a crusher

Good guys who know what they do - no one is wearing really dirty dresses.

Always nice to see a brand new bearing being smashed with a sledge hammer OMG

Вы же вроде занимаетесь постоянно ремонтом этих дробилок? Неужели постоянные подставки не сварить? Какого хрена изделие стоит на каком то хилом двутавре и трубе?

Eyes don't last long when unprotected while welding and burning. I've had a welding flash, and it isn't pleasant.And that was from one quick flash.

That new bearing is looking a little banged up already after the hammer installation

I love how the video is sped up to make them sound exactly like Minions - even down to the laugh at 3:28 - the resemblance is uncanny

Good Job 👍 ❤ Do Hard And You Will win the World ❤️

Sounds like the chipmunks Alvin, Simon, and Theodore talking on this video.

Can anyone tell me what it is they're repairing? Also the outside of the bearings don't seem to be resting on anything so what are they for? There must be more to it.

no anti seize grease on any threads

good start when you roll a bearing around in the dirt...

"Awesome Safety Shoes" OSHA would have a Heyday passing out fines over there.

What type of machinery did this come from, it would be great if you had showed the eventual usage but perhaps your shop only got the item?

There is always one guy sitting around and do nothing. 😂

You better have fast reflexes in that joint, jeesh did you see that guy jump like a cat!

Would rather see them hammer on a brass punch than on the race itself.

Steel toed sandals wouldn’t help at all with the weight of the side “shaft wheels”

They all must be wearing Nomex Habibs, lol!! using a torch and no one ignited themselves!!

All running around in their jim-jams and not a pair of steel toe capped boots to be seen. Adds another dimension to the term "flat feet"

The guy with the cutting torch was smart enough not to wear sandels.

Why they didnt put out the fire after plazma cuting? The oil/lubricant is burning, and they inhale the probably toxic fumes.

Wrap it up with old rags, dipped in oil, then burn it. Best method to lossen

Do you have access to a hydraulic press? Easiest method to remove large and small parts from this machine. All a hydraulic cylinder would need to do is to exert force on a scissor mechanism that is placed between the two metal parts to be separated. Simpler and easier to use than an Excavator Hammer attachment. It is also known as a gear or pulley pulling mechanism.

Штаны новые выдали работяге? А сварщика премии лишить.

Love those steel-toed sandals.

You guy’s are the best Hard working I love all your videos as I sit here in Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 UK and I can watch you all those thoughts of miles away I really enjoyed your video best of regards from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿🏴󠁧󠁢󠁳󠁣󠁴󠁿🙏🙏❤️❤️

Got some rock stars right there.

Its all about learning from others, using that "pecker" was a great idea. The lack of safety equipment is sad, reminds me of my starting my apprenticeship in the UK in 1964 we were issued with goggles, few wore them: no safety boots or ear protection and lots of lead, asbestos and mercury about about

Please get these guys some safety boots 🥾!

Always wear safety sandals!

I love the smell of grease burning in the morning.

Safety LAST! Safety shoes, hardhats, eye and ear protection plus many other safety issues disregarded. Not to worry, we have many people to take up the positions of the disabled/deceased! Wow!

In the entrance of the shop we can read a warning sign that says ; No safety glasses or steel toe boots beyond this point

The scale of this blows my mind! It looks like a pulley for a serpentine belt, and an automotive flywheel, but the men would have to be some tiny little elves! 🤪
