yup.. worrying idd... also..lets put it together withot any shims or anywear near enugh grease while we rub more sand into the bearings.... luckkily its a heavy machine... but idd worrying... but to be entierly fair...they do as best they can with limited tools and knowledge... im confident it will work for a long time after... (if it doesent stand still for prolonged times after it has rained... its not near enugh grease to protect from water damage...)
Welcome to the "Bigger Hammer" school of equipment repair!!! 🤣 This is much better than "The Three Stooges"!! Bearing assembly 101: "Wipe the bearing with the cloth that's laying on the dirt floor and then carefully assemble the cages and roller on the old paper box on the ground that's covered with sand and dust!!
As far as I could see, they only greased half of each bearing as well, so will the poor assembly method or the lack of grease cause the premature failure?
@@chrissometimes7473 i saw that too. I saw no indication on disassembly that this thing gets any lube from an external source so thats likely all the lube it will ever get. Its just gonna crash again but the customer will not know how shitty the repair was. Unless he watches it on You Tube of course.
Some of the best pollution controls I’ve ever seen. Environmental impact is near 0. Grease and oil reclamation is awesome. Just scoop it up and burn it in your kitchen stove. Employee protection from particulate inhalation is top notch. And check out the open toe foot protection. Wait I think Joe only has 7 toes.
notice how they never use any solvent to loosen nuts or bolts, the indian way.. that's why they suffer so much failure, they dont care but each time you do this the metal get deformed and worn, soon the nut or bolt does have the hold and strength.. FAIL especially on pressed on part its all about brute force for them 98% of the time, not good for these case hardened metals to be pounded on like this they are brittle and get hairline fractures, FAIL, specially bearing races so forth, but they do it all the time.. they will grind and weld spring steel, no jokes and never temper it again.. so the weak spot is the weld, it fails sooner than later.. and there goes another truck down the wrong side of the road, its job security for them I spose? but when people's lives are at stake, you need a different occupation.. here its just money, but motor vehicles they apply the same mentaily and procedures, brute force, call it a day
@@kewakl8891 Ok, this must be the reason why these workers are no longer wearing safety sandals. It seems for the same reason also safety hats and safety toilets are forbidden.
I can’t believe it out of all these videos with machine shops from India this is the cleanest shop I’ve seen, congratulations! I mean safety glasses, boots, gloves!
Interesting that the grease was pressed in after installation, that couldn’t possibly get beyond the inner bearing rib holding the two bearings sets. Talk about job security for repeat failures and repairs
на каленый вал насрали электродной сваркой и обточили - зачем такие трудности? можно было просто тряпок подмотать под подшипники, было бы примерно то же самое
Норм технология, под подшипник твердость не нужна особая. Более продвинутая наплавка спец присадкой в среде аргона или плазменное напыление, звучит и выглядит конечно оч современно но по сути тоже самое. Кстати сварщик не насрал, шлак корочкой отошел. Что без балды говорит о его хорошей квалификации. И кстати такие крупные и дорогие детали во всем мире только так и восстанавливают в основном. Пусть не смущает вас грязная обстановка кругом, так практически везде.
Everything that is removed falls into the dirt first. A hall that doesn't even have a proper concrete floor. Working with primitive means and without any safety at work. It looks like working in the Stone Age.
maybe if you didn't work in the dirt and mud you might not get new parts filthy, parts might last longer? good grief they just don't seem to understand what case hardened means or the process, so they put that case hardened race in a fire then just slap it on the axle, no more case hardened race.. wears prematurely, they make presses for these for a reason.. if you used ANY sort of temperature cheat for lack of a proper press you freeze the axle, it shrinks, build a wooden box to house the axle with about 6" clearance all around, place dry ice in with axle, it seal for 2-3 hours.. this doesn't affect the temper in any way, in fact there is evidence super freezing metal makes it even more durable... you don't put the brand new freakin bearing races in a fire, you just destroyed the temper.. good grief G&G Rock Crusher Repairs (ghetto and ghetto) we take the temper out your case hardened metals, so you don't have to!
29:40 There was a question with 4 answer to choose the right one What’s the smallest ball there is Answers 1- tip of the middle make it to ball 2-Pencil dust 3- grease 4- tip of the pen ball Who knows the Answer If u see the Grease under microscope it has been made with very little ball that make everything smooth😏 I hope someone like this 👍
Never use calipers on a moving object 🤦🏻♂️ which is a good way to wear down it for inaccurate measurements for the next time. I cringed too with the bearing rolled on the dirt floor.
*That was quite impressive, even the job security measures! 😂 If there's no grease on the inside of the bearings, it looks like it'll be back in the shop in another year.*
I read a comment on these once - 16th century men using 19th century tech to work on 20th century machines. Why to do they have concrete and brick literally making all the walls everywhere but not as the floors.
Gritty, dirty, imprecise work. In these videos it seems they're always working on dirt floors, using crude machinery, work no safety standards whatsoever.
It's the first time I've seen a ram being used to disassemble a crusher shaft. My grandfather took apart jaw crushers, my dad took apart crushers and until recently I took apart crushers. But I've never seen this. I wonder what condition the locknut seat on the masthead was in, after all that beating
@@t-bonearoni8566 Does he need a video to prove his job or ability?? If you are impressed by this caveman bull shit then you are easily impressed, like a 5 year old would be.
Is it just me or did it look like they didn't grease the bearings enough..I just saw one side getting grease.. seems like those big bearings should have been swimming in bearing grease
Normally you'd place some timber or something to absorb the blow, i was waiting to see how they screwed the locking nuts (castle nuts) back on, I'm not surprised they didn't show it has they'd destroyed the fine threads on the ends of the shaft.
I have actually used a swinging steel shaft like that in a machine shop and it works great. We made a bronze plate to bolt to the end of the shaft to protect it. Was a huge 8” diameter taper fit about 15” long. Had a big 40” diameter gear on it we had to get off. We heated the gear with torches and expected it to come right off because of the taper fit. No such luck. One of us made the bronze plate right quick while me and another guy found a big scrap shaft about the size these guys had. An hour later put heat back on the gear and 3 hits with the ram and it popped off. Big fun.
@@martinswiney2192 I did my apprenticeship on huge 20,000 ton crank and screw power presses, we had a purpose built ram 'Big Bertha' it had a eye fitted at the balance point, it was probably over an 100 years old, you never hit straight on to the end of a shaft, you'll mushroom it but even worse hit it against a fine thread on the end of the shaft, they didn't show putting the nuts they'd battered the life out of being put back on, they could have easily made a 'C' spanner, they heated the bearings with oily rags filling them with dirt, even before the invention of bearing heaters, 200 years ago they were put in a tub of oil and you put your fire under the tub, this machine will shake and rumble and last no time at all.
@@hetrodoxly1203 yeah. Thats why when we did it on the fly we took the extra time to find a bronze plate, just scrap that was handy. Drilled a bolt hole thru the middle and countersunk it so the bolt head was below flush (single bolt to hold cap in place, i think whoever assembled this had heated the gear slightly before assembly) then heated gear back up and whopped it. No damage to the shaft. And yes they ruined those bearings in several ways. Rolling i dirt and heating with fire. Notice the nice blue color of the inner race when they slide them on the shaft. Heat treating is gone now. I use an induction bearing heater all the time. Another fun story is when heating up a $15k bearing on a gear box rush rebuild. Late night. Pizza delivered. Then we remembered the bearing on the induction heater. It was well past blue on the inner and outer races and rollers. Boss man was supposed to be watching it but he was eating pizza like the rest of us. Lol.
@@martinswiney2192 I'm retired now but i was still heating bearings in oil up until i finished, small bearings don't need much heat, I'd place them on top of a radiator, if a large shaft had to pass through the bearings in their housing we'd shrink the shaft, put it in a bag and fill it with nitrogen, hard work but happy days now long gone, they no longer scrape phosphor bronze bearings, they're turned to size but don't last very long.
@@galreserve2322 According to your logic, it should be less than that. About, say, 10 cents per 24 hours? can you imagine how to survive with 1 dollar per day doing that job daily with such energy to begin with? the common sense left you entirely, it seemed.
abom eat your heart out. Love this kind of work. Super tough and they are impressive. The ram action is un-heard of here in anti-sketch countries. But when you need it you can do it.
The rubber drive belt will not Mar up the surface and it also grips better than a chain. Normally a big fabric lifting strap is used but guess you gotta work with what you have.
sincerity and know-how a lot of effort. good good night but Be sure to wear gloves Work efficiency doubles. and Bad substances can cause disease through the skin.
whoever owns this machine would do himself a great favor if he had sealed bearings fabricated for that shaft, look at all the dirt and grime inthe grease, unsealed bearings ina rock crusher, gee dunno how that would happen? sealed bearings, or seals..
Bravo pour ce travail de restauration. Ici en Europe, aucun technicien ose faire ce que vous faite. Si cela fonctionne, c'est vous qui serrer la première puissance industrielle du monde. Le travail fini toujours par rendre les hommes fière et indépendant. Merci pour votre vidéo. Benny Rooman à Bruxelles.
Vielleicht weil es keiner bezahlen kann? Bei unseren Löhnen! Außerdem geht es auch um Betriebssicherheit und in Pakistan gibt es garantiert laschere Vorschriften als in der EU, gerade in der EU.🤔
В тех крышках которые закрывают подшипники , есть проточка под сальники , но вот сальников я там не увидел , видимо работать оно будет "очень долго " .
At 24:49 it's still delaminating. These people only repair enough to get it out the door. No pride in workmanship. FYI Amazing Technology, Restoration means bringing somthing back to like new condition, this repair is still in the scrap core condition. I know they can do it right but that takes more time and supplies which makes less money for the big boss. So around, around we go.
У таких дробилок срок службы 80 лет при адекватной эксплуатации. В этой дробилки по ее состоянию видно что очень лайтовая эксплуатация. Единственная беда много пили. Если бы они поставили маслёнки и пилезащиту, то она бы прослужила ещё 20 лет. А так привезут ее через два года, опять на наварку и проточку посадочных потому что и за малого количества смазки и большого количества пыли идёт износ. Короче робота будет😉
rolling bearings are used at a different temperature and in a clean environment. Not in a dusty environment. Because dirt will get into the bearing and thus degrade it. It will be noisy and may crack.
Great jobs guys. You've put a man and machine, crew back to work. Ignore the complainers, they all live in some mechanical world when the hardest thing they do is program some robot to do what you guys did with brute force.
