When putting roller or ball bearings on a shaft, try putting the bearings in a plastic bag and in a freezer for a few hours. When you take them out of the freezer, the inner bearing race will contract enough to just slide them onto the shaft without having to hammer them in. Great video!
Very clear & educational video which has taught me a lot. When you see other videos on the net showing tanks that have exploded with rust on the inside, I think you are very wise not to push it to its maximum pressure.
Thanks
Although he's doing a few mistakes, The guy is eager, and willing. He'll do well over time
What mistake!
Pratik Rathid he didn’t do a hydrostatic test on the tank. I can’t even imagine how much rust is in it.
@@pratikrathid3261 never hit the bearing on the outer race when installing on a shaft, always the inner race for shaft or outer race for case and preferably pressing better than whacking.
I like everything about this except for two things. You painted sealing surfaces on the pump and you doused your plants in deisel. Other than that, a tremendous improvement.
Hammering the wrist pins out makes baby Jesus cry
Luke Anderson so did hammering on that new bearing like that 😬
@TheJR1948 THANK YOU! I thought I was the only one to notice...
Remember 1. Do not paint surfaces under sealings 2. Do not install bearings like in this video
1. You can under if you have a proper ventilated enclosed setup with fans and filters. This would be better than outdoors because it would be free of dust and wind. But unless you have a paint booth setup, it ought to be done outdoors on a good day. 2. Hammering on the outer ring on a bearing is a good way to damage it. I find the best way to install a bearing is to use a deep socket or metal pipe that fits perfectly over the shaft and sits on the inner ring. Then you can either hammer it or use a press. 3. I wouldn’t be too hard on the guy. He did a lot of things correctly for the most part, and sure there were a few head scratching moments. As an engineer and mechanic, sometimes you’ve got to use what you’ve got to complete a project to the best of your abilities.
3. don´t paint the heat exchanging parts :) 4. don´t place the piston rings openings facing to the same side 5. Check the tank from inside because of rust 6. If it works, don´t give a shit ... well done
@@Omegadoomship Both of you are forgot the 120 degree angle between piston rings gaps and disaligning piston rings gaps with geometrical axles of piston pin. And, IMHO, compressor oil is not optimal solution for the compressors with oil sump. My 2 piston 400l/min compressor is running with 5w40 API SN motor oil, such as i use in my car.
This dude smashed em, it's like not changing them
@@WhiteWingsGarage i don't like at all how he " repeared" the engine, old pistons, he hit the rod with the hammer, bearings smashed with the hammer too, and all the other stuff
Will be cool to see you do more restorations using this aircompressor you restored.
Yes bro I will do
I saw those motor bikes in the beginning and my heart melted.
Parabéns,ótima restauração,perfeita.
I loved hearing the adhan in the background
Great job on rebuilding this air compressor. And the electric motor. I didn’t know they made a buffing or sanding wheel to clean off the rotor on the the motor. Well done.👍🏻
That was abrasive wheel
Well, not to say that this was the best idea :since removing all the rust, you also remove part of the metal breaking the electromagnetic gap between the rotor and the stator . In addition, there is also balancing of the motor rotor (imho imho ).But this method is the least of all evils.
big table of cold degreaser an diesel olie.... Cleans stuff up amazingly well
Lucky the tank didnt explode Didnt even check to see if there was any water in the tank it could of been rusted through
I'm surprised he didn't hydro test first thing. It would suck to put in all that effort on a bad tank, or worse have it rupture under pressure.
Tip for putting on bearings way easier: put the shaft in the freezer for a while and warm up the bearing a little bit (hot air gun but be careful if yoyr bearing isn't rated for sutch heat) the bearing will just fall on the shaft and will be immovable with bare hands in not even a second. How do I know this? It did this with all the bearings in my motorcycle engine and it worked great.
Thanks
Hurt to se pounding like that..
My dad was great at things like this. He was truly a master mechanic. One of the few like this master here. Of course, most people couldn't care less. The massess would rather glorify some pretty face, or pencil pusher. I'm pretty happy that video and internet tech has evolved so these folks can showcase their work. The average person may now be able to digest the amazing craftsmanship and insane level-of-effort that these masters put forth.
Thanks a lot and great respect for your father
amazing restoration , and the answer is yes always replace safety parts !!
Overall you did a very good job restoring this compressor although some work method are not ideal but acceptable ... enjoy watching your work very much...
Thanks bro and I think you are talking about bearing installing.
I really appreciate having no music, but you could talk once in a while though....anyway, nice video. I learned a lot....Thanks, Bob
Ooooo I see an old Hobart Mixer @0:06 that would be fun to restore and have ~Pastry Chef
That looks amazing. Great work and well put together. Trey a video and talk through it.
Thanks bro
Please, loosen the four screws supporting the motor and put some tension on to the belt by pulling on the motor. That what I do, when I replace the belt on my compressor.
Isnt 166$ too expensive for a rusty, not running compressor ?
Yes
Well it looks like it’s a big capacity 4hp industrial air compressor they go new for like 300 to almost 700 or more and that’s euro’s
Depends on in which country you live. Could imagine that in India you dont have to complain about such a price because of what is available there. Maybe its the cheapest 4HP compressor he could find (better then nothing)
Most certainly, but I guess that price could vary widely depending on region. You could pick up a small compressor like that around here new for 250-300 USD. If you searched craigslist or Facebook, you could find one for next to nothing or trade. Hell I've seen folk give them away if a part breaks or they bought a new one, either give it to someone who asks or put it by the road with a 'Free" sign on it. 2$/kg is almost like buying scrap, but the heaviest thing on that is the motor and compressor, take those off and that tank would probably weigh 20 pounds or less.
For 200$ you can get 4hp new compressor
I recently rebuilt my stepfather's '70s Wards compressor. Some of the reed valves in the head were hard to find! I had to make new gaskets. The unloading check valve was a challenge to find too. The surprising thing was that there was nearly a quart of water in the tank! The drain valve was damaged, and I don't know when the last time it was used. I installed a new Hromee extended drain valve, which is easy to get to. Now I purge condensation every time I use the compressor.
Very cool!
Good job! You restored it with what was on hand and repaired and cleaned up old quality parts instead of buying new.
Yes, thanks
Good job my friend for giving me something to watch at 3 am. 😂😂 but still good job
I have watched a couple of your restoration videos now and I am impressed with the level of detail you go into. However, I wanted to see what you did to check the integrity of the steel air cylinder which as you know, are prone to internal rusting over the years and have the potential to crack and explode. I did not see you doing any checks for rust nor cleaning/ internal treatment on the cylinder. Can you comment on this? Thanks
Great job and the steps by steps of video, work, and cost. Thanks for sharing JazakAllah
Muy buen restauracion este video es muy bueno para los pintores automotrices saludos!
💯🏅🏅🏅🏅ماشاء الله تبارك الله ممتاز جداً
166 for a not working old compressor, that could also have rust in the reservoir ? That’s definitely not a good deal
Was thinking that too
$166 time bomb 💣 tic tic
the tank look great from the outside. I know it can be completly rusted inside but those old tanks were good. You dont ear that much accidents about tanks explosions.
new paint on your buffer to, amazing work, professional. thanks
Thank you too!
Τέλεια η επισκευή του κομπρεσέρ υψηλής πίεσης αερος.
Great restoration and it was bad luck to get one that needed so much work. I think it is fine to reuse safety parts if they are cleaned and tested. My worry is that it looks like there is no earth wire. I do have a couple of questions please. What was the total cost including the original $166 and how much would a compressor like that cost new where you are? Where did you find a replacement con rod? It looks like you are experienced in engine rebuilding as not many people have their own piston ring expanders. Were you able to get the machining done for free? as I’m assuming you may own or work at an engine reconditioning shop. Lastly, are you in Pakistan as I thought I heard calls to prayer in the background. Thanks Stuart 🇦🇺
29:12 that constant hiss from the head unloader means theres a leak from the MPV/non-return valve. it should hiss but reduce to nothing in a short time, rather than what its doing
If only it was painted the right color! 🔴 Otherwise, it's beautiful! I wish mine was that big.
KAMAAL HAI 👌🏻👌🏻👌🏻
$166 for a used/broken air compressor? Doesn't really seem like a good deal.
@Brandon RG the taxes are higher also. That is why many in countries outside the US and Canada, people fix and restore instead of throw away and buy new. New products are cheap junk compared to older products anyway. Cubans for example are still running cars from the 50's there.
@@lou704 that is because of the trade embargo. In Cuba they actually have a lot of newer Russian shit too. Doesn’t look as good for the tourists though?
I think he got his money's worth with the KZhead views...
Wouldnt have youtube content otherwise plus yt viewer revenue can make it worthwhile
Owww PAIN REMOVER, i'll drink some of that!
haha yea i loved that as well
I learned a lot from this video, thanks bro. Hopefully there will be something better up front....😍
Oi, opening that pump up gives me thoughts of the next day at the hardware store. Slap down your list and relay to the lucky guy helping you: "To this line, I need one of everything. To this line, 3 of everything." *Stand back and watch for head explosion
Simplesmente fantástico!!! Parabéns pela habilidade e dom

Ficou top.. Parabens pela belissima restauração.. 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
I would love to have his skills! Great job!
You're joking right? Have you read the comments?
@@CableWrestler these are hack skills that no one should try to emulate
Beautiful restoration and saving a compressor from scrap
17:35, did anyone else notice how he put Teflon tape on those JIC/SAE/AN fittings? They don't seat on the threads, they seat on the cone.
I'm an hvac tech, seeing teflon tape on those flare connections hurt, and so did the unloader that doesn't re-seat, and the bearings being hammered in by their puter race, and crankcase to cylinder gaskets on top of paint. . . . Sooooo many things done incorrectly.
Watching that bearing installation hurt. You've probably reduced the life of those things by 30% by "installing" them like that.
Never ever do that with a bearing.
@TheJR1948 I'm gonna guess the "mains" in this gentleman's case are just as susceptible to fire.
It was a rubber mallet so I don't think it hurt them as much as you think. They are little tougher than that. If it had a larger torque load I would be worried. 4 hp. Probably not
@@chrislangdell117 if you hit the outer race with anything making the bearing "flex" it will actually damage it. Doesn't really matter what you hit it with.
Using a wrench later was a good idea, but the "normal" way to install new bearings is to put a piece of pipe over the inside of the bearing and hit that pipe with a hammer.
Thanks a lot on my ship we have this type of air compressor but I don’t know how to overhauling this video makes easy for me
i see a lot of negative comments, but also a lot more tips than just negative comments :-) i say great job taking on such a big task. you can be pround of yourself, and the journey wanting to learn :-)
Thanks brother for appreciate
4:12 ASMR blyt. 7:47 где проставка деревянная(полимерная) с противоположной стороны оберегающая кривошипно шатунный механизм. 11:34 плохой хон. соответственно и результат. 17:33 этим гофрамм "пришол северный пушной зверёк". Они не охлаждают. 21:24 не стоило увеличивать зазор магнитный между статором и ротором. 27:45 их нужно было лопнуть.
А ещё ресивер опрессовать водой забыли. Но индусы верят в переселение душ, потому им пофиг...
If "I know a guy that can do it cheaper" had a KZhead channel...
Mantaaap iron man R 👍👍👍 sangat kreatif dan inovatif.sukses selalu salam dr angler pontianak 🙏
As a compressor engineer thinking of cost to the customer,, this machine would end up in the scrap heap.. But it's an ideal project to take on, if you have nothing else better to do with your time.
I missed how you cleaned the inside of the tank.
If it wasn't maintained and is rusty it's a bomb just waiting to pop....
If the compressor was as dirty as it was, the inside of the tank would be worse, that is a bomb waiting to explode
Engineering aside, anyone else feel sorry for the poor plants being sprayed?
Big Tam's Garage no
Yeh someone will walk pass them and will say never saw blue plants before.

did a great job with the tools you have, US people don´t understand what is to live in a third country, Im from Argentina, and some times you should do your best with limited resources
Thanks bro for appreciate
Doesn’t take that much more to mask off sealing surfaces and find a pipe the correct size to install the bearings, js if ur concerned with money u might want ur tools to last longer before needing a whole rebuild. Especially considering these are free to do. It’s all constructive criticism. And safety concerns everyone
Apparently the comments section is full of mechanics, electricians, engineers, scientists and quality assurance officers.
You are very funny bro
there are about a little 850.000 viewers of this video at present. there's a relevant high probability that some of them are mechanics, electricians, engineers, scientists or quality assurance officers. ^_^ cheers
This is what we do with our free time bud, I’m sorry you don’t have anything positive to say.
And some of us have pride in our workmanship. Roughshod like this makes my skin crawl. I don't care if "it works" if it's not going to work right.
Did you pressure test the tank? With it being so old were you worried about rust inside the tank?
I'm also very curious.
Great restoration, but you'll definitely want to replace the old electrolytic start and run capacitors on that motor.
RESPECT FOR YOU !!!
thats a vintage air compressor? jeez, my dad has one that looks the same, and its still running well
Oop
When this thing blows up, it will mean one less youtube channel.
Gostei,bom trabalho. 🇧🇷
مجھے بہت خوشی ہوئی یہ دیکھ کے کہ کوئی پاکستانی بھی restoration کی فیلڈ میں اتنا کمال رکھتا ہے. GOOD JOB DONE SIR. I SALUTE YOU
Thanks brother
$166 was far too much to pay for that thing.
more like 10$...
166 of their money, not USD I think!
@@thethinbluelineZ06 spesificly said usd
I would rather buy a new one for $180
if it at my place the price for new one is about 450 usd without any free gift such as blower or pipe or even quick release connector 🤣🤣
С 65 поршнями этот компрессор должен качать 8 атмосфер за 2 минуты, а тут печальный результат
The old green paint was also nice to be honest 😍
مشاء الله عليك .. ممتع ..👍🏻. .😌
Ну да собрал хорошо , в место 8 очков с напоследнем дыхание 3 очка качает , клапана кто будет притирать лепестковые
У меня есть Grand Valve, но потерял запись видео.
@@IronManRestoration Работа проведена титаническая, а как насчёт коррозии в ресивере?
It's cool and all but pressurized vessels ought to be used brand new and tested..... not old and rusty. Very cute bomb though!
So beautiful video
I like seeing the original logos and text on restored machinery. If there were any way to copy the old graphics from the tank, clean it up in Photoshop or something, than send it off to a sign shop to print up a new one, that would be the cherry on top. Otherwise, great job, man. 👍
I love your vídeos 👍👍
Thanks brother
That's a good job honestly
Got one from 1960 that still sort of works
beating the bearing on, LOL. gaskets are not high temp. and the oil had a detergent in it. Aside from those huge issues, nice work. LOL
16:00 do not tap on the outside of the bearing but on the inner ring with a tube
ok bro
Beautiful instructions - ,, how to destroy new fur ,,
It needs the same sticker, at least :-) Bravo for the machine work on the cylinders
Thank you
Great video it taught me a few things. Keep up with the videos.
Restauração profissional, parabéns👏👏👍👍🇧🇷
17:40 thread tape? on JIC style fittings? ooook
awesome restoration.
Awesome restoration job worthy of 3 or 4 parts. I am sure you had enough footage for them. That way we will get to see your beautiful work in more details. Like for example checking the motor capacitors or sanding the tank before the primer. Every bit is interesting for some of us. Also i would've loved to see your own logo on the tank, you certainly deserve it. Good luck and keep those great videos coming.
thanks bro for good advise and appreciate
All those air compressors in the yard screaming, "Pick me! Pick me!"
🤣🤣🤣🤣
just wondering if he cleaned the inside of the tank, no idea if there would be rust.
May I ask why the preference of non - power tools? Can appreciate the patience in that.
Amazing work. Beautiful.
Thank you very much!
Mashallah, good job
166$ now way you can get them allot cheaper here. it sounds not great butt nice resto.
Probably something to do with the fact that he installed the bearings with a hammer...
Best work and good skill
Olá, Você fez um ótimo trabalho. Parabéns. Que tipo de diluente e tinta você usou para pintar o tanque de ar?
For same reason, I swear I seen exact video this before
You probably saw it on a chinese channel. The units on the scale are metric and it's a 3 phase compressor and the brand label on it is in chinese. In the US most people seem to struggle to get 220 single phase in their shops.
@@rimmersbryggeri ohh that makes sense 👍👍 keep up the good work
16:00 punching into outside rim of the bearing can damage that bearing never do that !!!!
I was about to write that as well. If you fit bearings on the shaft always use inner run, if you fit bearings in to housing use outside run.
@@przemm87 you are 100% right my polish friend :D
@@przemm87 i will do the same. it hurt when i saw it. seriously.
Just goes to show that all you need in your toolbox is a hammer and a FBS (Fairly Big Screwdriver)! However, you have to work with what you have and stay within your budget no matter how small it is. It's OK to say fit a new crank or a new whatever but if you can't afford then you can't do it. Given his obvious constraints he did a good job.
Fine work my friend
Please heat up the inner ring of the bearing and dont hammer on the outer ring as an engine rebuilder that hurts my soul so bad ._.
Momo commented the same thing on another comment 😂 being an engineer doesn’t mean poop if u haven’t been around the machines ur working with
@@knightfall7534 where im from, u have booksmart people, and then people with common sense. His shit works but like the other gentleman said, he prolly took years off the life of a rebuilt unit.....u can make it look pretty but its still a piece of chit. My opinion only
You are supposed to hit a bearing on the outer ring, not the inner.
@@ronbeton1999 true...but if u heat the bearing it will slide into place
So I looked some things up: when mounting a bearing to a shaft press the inner ring, when mounting in a housing press the outer ring. Not hammering like a fool like in this vid 😂😂
"Propper Tools" Smacks the outer bearing ring down with a hammer...
I did that on my motorcycle engine with both crank bearings and the clutch bearing.. except it was only the bearing into the crankcase, I specifically didn't hit the inner ring and it had no crank assembled yet so.. does that count?
i appreciate so much your channel i have 2 air compressor i got I'm going to make sure i watch your videos
Awesome thanks a lot for appreciating
