Not rubber but leather. You make them using a piece of leather, and soaking it in hoof oil, then get the bend in it by cutting out the large circle, and assembling it on the shaft in reverse, with the large washer at the far end. Then put in the housing, well oiled, and making the softened leather gradually bend to fit the housing, then leave in there for a few hours, pull out and assemble the right way round. The leather is treated with hoof oil or Dubbin, both available probably at the local store, the Dubbin being used for suede leather shoes, as it is a pale yellow leather treatment, and thus on suede it does not darken it like shoe polish, though boot polish is likely what was used on there over the years.
Woah. I never thought we'd have a discussion about dubbin on here. :)
Neatsfoot oil, also. If the leather isn't ripped or torn probably vegetable oil would be fine to soften it up. I often use most any light oil.
Isn't the seal on the hose also leather? So it's a bit of shame to replace it with that newfangled rubber o-ring.
@@alexej01 Correct, all the seals would be leather soaked in oil. The check valve might be rubber, I don't recall the detail of my (almost identical, slightly newer) pump.
Agree, thick leather. Same in optimus primus, petromax, etc. We used to oil it with weapon - oil when i was in the army.
Nowadays its just a o-ring
That looks exactly like the pump I used as a kid for my bicycle tires , usually all I had to do was pull the piston out and spread it out a bit and put a bit of oil in there so it made a better seal. I think the piston is leather and not rubber. Those cheap pumps didn't have a check valve in them. You needed to be fast to disconnect the hose from tire stem while pushing down on the pump so not much air would escape from tire. New pumps are so much better these days !
Yes leather.
@@hwassie No rubber.
The seals were originally leather, but that may be a later version; the type of Schrader valve adapter does seem to indicate it's a later design.
@@cambridgemart2075 yeah I had one with a screw on hose valve too and that one was a real pain to get off without letting so much of the air out !
It seems like this pump must have a check valve or else the balloon wouldn't inflate. Is it in the hose fitting near the base, I wonder?
Really enjoy your troubleshooting and electronics repair videos the most of any on CZcams. But videos like this or a lot of fun too. Similar to your refrigeration compressor series you did a few years back. Fun to watch and different than your normal repertoire
As others have said, the foot stand is the wrong way round. It's correct on the first frame of the video. It will hold it more firmly to the floor on the upstroke when in the correct position. Interesting video 🙂
I have to say that I really like any kind of your videos.
Please continue making them, no matter which topic.
Something other than electronics is also very interesting, especially old technology. And check valves are basically the same as diodes.
Just loved this video. My hand pump broke today. I was just about to order a new fancy one, when I found this video. Yes the rubber part had got stuck in the bottom. I have managed to fix it thanks to this video. Thank you so much.
Danke!
Nice!
My Grandpa still use a similar air pump for his Bike.
The 'clean' side of the big washer is cleaner because every pump strike the rubber press against it and kind of press dirt out or grind very little.
You see the small bending of the washer.. so you know the big main force during an air pump strike comes from above/the handle going down.
Forcing the nut in the center down .. but the outer ring of rubber together with the increasing air pressure try to push the washer up.
I would try to use a better grease.. no random WD40 spraycan or similiar :-/
Most old rubbers nemisis is not their oldeness .. its modern aggressiv oil.
Try vaseline(petroleum jelly/petrolatum?) , vegetable oil or specialised grease for rubber.
Thanks for non electronic videos too ;-)
And nice to know that there are people who are helpful and not only looking on the Smartphones the whole day, during driving or crossing a railway track.
You are exactly right and even though these are leather pieces in this video... lubricants containing petroleum distillates can do similar things to leather overtime. According to how the leather was originally tanned.... Defines how bad it gets and how fast. But you absolutely want to keep petroleum jelly or anyting containing petroleum away from a lot of rubbers if possible. One of the simplest things is that silicone type grease at the auto parts store for light bulbs and stuff like that. A lot of it is totally most of the other harmful distillates.
There are a lot of specialized lubricants used in aerospace ect..... that are totally petroleum-free. And the first thing someone can do is to throw out anything made by "armor All"or other automotive detailing stuff... And replace it with the 3M stuff that does the same thing but without any petroleum distillates. It's so funny because "armor All" overtime destroys rubber and plastic and other composites... Not the armor All But the varying levels of petroleum distillates. The first place one will see this is in the rubber weatherproofing trim around doors and windows. They get harder and more brittle and no matter how much armor All use... They soften up temporarily only to dry out even more extremely. It's lighter than with some good petroleum free dielectric/silicone grease... And watch the magic happen. (Then probably take off the excess that wasn't absorbed)
So many of the cleaning and detailing products out there will destroy just about any composite given enough time or penetration. Maybe not a big deal in our throwaway world where people only keep cars and devices for a few years... But becomes much more pertinent it working with actually well-designed and timeless scientific equipment, automobiles, or other engineering marvels
Very similar were bicycle tyre pumps in the UK in the 50s and 60s. Often had 2 fold out bits to stand on where yours has one. Super simple and the diaphram was leather and could be easily replaced if it wore out. Things were made to last a lifetime back then.
I love mechanical repair diversions like this. Some of my favorite videos on Big Clive's channel are about plumbing.
You're spot on about the check valve being inside the hose fitting. It's construction is often similar to the piston seal, but backwards (and obviously smaller), so it's pushed closed by pressure from the tire.
Agreed. And some of my favorite videos on this channel are about plumbing with his "unauthorized plumber" who is a cat. Mostly gas water heater videos if I remember correctly
む…Piston.. Oneway valve.. that's a DIODE!!
More of this please in the future.
Nice restoration, one thing you put the wire you step on to hold the pump backwards so it jumps up when you pull the handle.
Ah this brings back so many memories.
I like the electronics too but this is good and im happy u made and posted this.
Tbh tho, if u did a vid of u picking your nose or cooking toast or having a conversation with the cat id still watch and enjoy it and i wouldn't be the only one
I am a hungarian. My grandfather gave me a pump, and that looks like this. It works perfectly in this time. Only the gasket needed to replace.
Nice video 👍
Great restoration video much better than the other ones with all the fake rust that I watch
I remember these pumps from the '90s, they were made in the Eastern bloc for decades. My brother even had a smaller one made in GDR or CSSR that could pump a volleyball - I just connected a plastic tube and use it to do some experiments with compressed air when I was a kid, haha!
Super restoration Danyk... I never thought you were going to do the painting and wood polishing too !! Wonderfully done...but how could YOU not know, from the feel, that it was leather ? I was shouting at my screen, "IT'S LEATHER, I'TS L-E-A-T-H-E-R" 😂😂
Ja bych rekl, ze to bylo super, ted uz vim jak ji opravit az se v garazi pokazi :D
prej vintáž...
Vždyť jsem tím před obědem dneska foukal favoritku i favorita.
That’s amazing! Great video and very entertaining. Incorporating other kind of stuff other than electronics is refreshing too 👍🏼 have a nice day mister
old is gold
You do what you want, it's all good stuff.
Great video, thank you.
Soviet-era Grey look like the correct colour.
;)
Recently I repaired a similar pump. It had no compression and it was leaking air at the bottom. I added a thin rubber ring around the old rubber or leather thing, oil it and I push it over the other end with the stand. I used pliers to make sure it's spread to touch the walls of the tube. I added teflon tape to seal the air leak. It use to take 20 pumps to inflate my bicycle, now it takes 5 or 6. There is vacuum that pull the lever down once I begin pumping. To let air in I have to pull up so the leather ring is over the small hole at the top.
The valve in the tire could be pushed open by the air pressure.
What a nice old pump, well worth your effort :-D
If it's not as good as you expected, perhaps make a disk of wood or plastic to apply a little pressure to the inside of the old rubber cup.
Maybe Chop up a worn out car tyre to make a rubber disk perhaps.
No switch mode supplies were hurt in this video lol :-D
This video shows your mechanical ability which adds to your electronic ability. More of these type videos makes sense so everyone can enjoy your other talents.
I'm here for the troubleshooting train of thought, and this one is no different. Thanks for the videos!
You can make another with leather.
You can buy the leather piston in any bike shop in czechia.
Love the restoration videos, great job
I still have the tire pump I bought at the age of eight, very similar to yours! Those rubber parts are leather.
On mine, the pintle style check valve is dropped into the base just before attaching the hose.
There are actually pneumatic circuit boards so this isn’t necessarily off topic!
I was shown one when I was studying many years ago. They were used in oil refineries etc where sparks cannot be allowed to happen.
They consisted of two plates one on top of the other. Traces were raised paths in the top plate, forming tubes. Resistors were venturi in those tubes. Current was airflow in the tubes. Voltage was air pressure. Capacitors were little spring loaded bellows. Switches and relays were little pistons. I don’t recall too much as it was long ago but I do remember that most basic components can be simulated with air devices.
It's a pneumatic rectifier 🤔
I worked as a biomed technician and rebuilt all kinds of hospital equipment. We often had to rebuild surgery and exam tables. even modern tables that use electric or mechanical hydraulic height adjustment all use leather seals. we had rolls of different thickness leather and large sharp hole punches and just cut our own replacement cups and using nylon or wood hammer, reshaped it into the cup. they last years with very little failure. There were a couple of company's that fit there tables with rubber or nitrile orings but when they fail it will sometimes just drop and you can imagine the issue in a hospital setting that would be...
Brilliant!
Thanks for this video Daniel, it's refreshing to have different subjects. My Dad, who passed away
40 years ago had the black but otherwise identical version of this pump. Sadly like many of his old
tools they went to the tip after no one wanted them.If it's got mineral grease or oil on a rubber piston
it will gradually perish. You can use vegetable oil to lubricate it without worrying about perishing.
Could the piston and other fibre washer possibly be leather/thick hide by any chance? Also if the
nut thread isn't m8x1.25mm, it may be 5/16 UNC thread, they look very close. I think these pumps
may have came from the army originally.
Good job, congratulations 👌.
Funny that I only stumbled on it right now.
I have the exact same pump from my father in green.
Happy to konw what to make out of it if it breaks someday !
clean restoration work man nice 👌
I think this was quite popular pump in the central Europe back in the days. I have exactly the same type somewhere in the basement.
My grandfather still has the same Pump
You done good job. Painting was important because you prevented rust. So i could work for another 50 years.
DoideGoneWild = AirValveGoneWild 😂
What
The rubber is not rubber it is leather. I have a pump the same as yours.
It's leather.
They actually sell replacements of different sizes at my local hardware store.
Heck Yeah!!!
I dig it!
Your mechanical air pressure generator machine is awesome. 😄
I would have expected to see a simple one way check valve at the base of the pump, but I suppose it would work without one. You can replace the rubber diaphragm with a leather one, you just take a scrap of this leather, cut it in a circle perhaps 2cm wider than the diameter of the pump body, soak it in water then assemble it back to front on the pump shaft so it's nut, small washer, diaphragm, large washer, then nut, insert it into the pump body and leave it to dry, once dry remove it, trim the edges, soak it in olive oil and assemble it the correct way round.
The schraeder valve the pump connects to works as the one-way system. Air pressure opend the valve and lets air into the tyre and then it shuts as you pull up the plunger so air can only feed in past the diaphram.
@@MikeB_UK Yes, the Schrader valve has a spring loaded poppet valve, but if the look at the connector in the video it has a pin to keep the poppet valve open while connected, I don't think I've ever come across a pump that uses air pressure to force the poppet valve open.
as complete can be, thank you,☆;
Something silly that happened to me is that I decided to replace my old pump with something with a gauge on it which turned out to be a fake gauge, should have stayed with the old pump from the 90s because at least it's honest and reliable!
Super! Keep it up!
You're missing the part of restoration videos where they just buy an entirely new one as they don't even know how to get it back together :^)
Nice
Ano, všude byla kůže místo gumy. A ještě šlapka pro nohu byla původně na druhé straně.
Foot stand is on wrong side
It is not rubber, it is leather (the material of the piston). It has to be full of grease, if not the leather will go useless. One way valve is in the bottom of the cylinder, it has a small ball inside with cone and preventing the ball shape of the case of the valve. This pump will never be completely broken, always you can repair it in easy way. I use to have such a pump when I was young, 30 years ago, it was stolen from my motorcycle garage with other tools.
A 1.2 Amp DiodeGoneWild plank!
My one had a Leather seal in it not rubber, great video it was interesting
Nice video! I missed the schematics though 😁 Btw, I think you may have put the piece you step on backwards...
My father had a pump like this and it still works fine. We use it to inflate motorcycle and bicycle wheels.
The thought process used for diagnosing and repair, is the same for electronics and mechanical things. It was designed to work. It did work and now it doesn't. Why? Pumps like that are very common and used for years. The old ones (like yours) use leather for the piston and washers. Rubber was only used when modern synthetics were developed. There was never a one way valve. It relied on the valve on the tyre, to stop it blowing back.
My grandpa uses a very similar pump for his car tyres. One time he said it was an accessory for the first car he owned, together with a massive wheel wrench he keeps in his current car as a self-defense weapon lol
Nice.
5:39 That is the right way, it's probably leather instead of rubber and you can make a new one from an old peace of leather and force in into the tube backwards so it takes the right shape and than turn it around for final installation.
Very nice vintage pump! I got one from my great grandpa a couple years back that I used to inflate my bike tires, the leather plunger has just about gone, so I need to replace it, it works great beside that. It must be from the late 1940s/early 50s, and was sold by Kmart, remnants of the sticker on it that has an old Kmart billboard with a 1940s or 50s car below it.
Nice to see you here!
@@versedbridge4007 indeed :)
This vintage model is the exact one I saw for sale here, lol.
Mój sąsiad miał taką. Ona może mieć faktycznie jakieś 40-50 lat. Te tłoki psuły się niemiłosiernie.
"It's my way or the highway"
Or as Danny said:
"It's either going to be this video or no video today." Love it !
An "engineering" mindset and some "common sense" goes a long way
Is there anything you can not fix?
/chriV
Nicely restored...but where is cat?
I was going to say that it does not need a one-way valve in the pump output line because the valve in the tyre provides that but then you went and pumped up a balloon which proves me wrong.
Thanks and good job on the pump. These are very useful devices that don't need power to work and have no motor to break. I've lost track of mine and can't even remember when I last saw a manual air pump, but it's certainly been a decade or longer. Mine's probably hidden under something in my garage.
Nice work!
(everything doesn't have to be about electricity or electronics - i like mixed content).
It's made of leather and all you have to do is get a flat piece of leather, and force it around the washer into the cylinder, with some oil in there and it will sort itself out
Don't you just hate it when your paouwump stops verrking?
Thank you for this different kind of video.
Did you choose a paint colour to match your Crocs?
Don’t worry about doing non-electronics videos. They are still interesting. I enjoyed your old vacuum pump videos.
Top cool
Use a flexible, greased leather not rubber. I use the same pump for my bicycle. It worked fine for years. Then the leather was dry and needed to be greased.
Whaaaat, no electronics in the pump? I'm sad.☹🤣 Interesting but dear Dany I love my XIAOMI Mijia Pump by Amazon ☺👍
Líbí se mně, jak tomu koženýmu kolečku říkáš "rubber" 🙂 Někdo to už složil špatně před tebou, ta menší podložka patří dovnitř, větší zvenku. Povolení té matičky je "common failure" 😀
You put the "foot handle" on the other side.
Yes.. i think that's one of the things that doesn't botter him.. but it's kind of easier handling to to have the foot handle in the original postion
Add a pressure gauge now for improved pump
you can build some serious muscle with that pump
Actually it wears down back your substantially
Fajno
I think the pump does take in air from that hole near the top of the cylinder. Why? I can hear some short, quick hissing just before the piston hits the top of the cylinder, indicating that the piston creates a vacuum on its way up and allows air to fill that vacuum once the piston has passed that hole.
I never opened my pump.
Thank you.
I have nearly the same one the funny thing is I bought it a year ago in a Chinese shop and it was probably made recently😂 yet it looks like it’s decades old
But where is the transformer autopsy? Are YOU the diode that has gone wild? lol
It have at least 40 years. My grandfather have the same air pump.
It looks like it might be good to replace the rubber... but I have no idea of what you could replace it with... so perhaps cleaning it up is all that can be done.
..... looks like it's going to work OK anyway.
That's a leather cup, you can see the skin texture on the flatter side, longer lasting than any leather, not vegan friendly, but who cares, it's a tool... :P

We found a single foot pump in the building we use as a detached garage
There are phones with schematics available made by Fairphone. You can easily take them apart and replace modules like the battery, screen or cameras, or even diagnose the board if you have a microscope and precision soldering technology. They don’t have a great power to price ratio but neither do flagship phones that cost 3-5 times the cheaper model, with no difference except a better camera and the microSD slot being replaced with copious amounts of on-board storage, and the headphone jack with nothing. I think that the Fairphone’s repairability may be worth it in the long term if parts continue to be available. Make sure to let them know there is demand for such devices!
Then you only need fully open source software on those with the support of your business partners (banks, government, etc). Let me know when we're there.
@@atdzsny I’m talking about hardware repairability.
Anyway, while it’s true that not every app you need is FOSS, an AOSP-based ROM with Open Gapps will get you a good privacy/functionality balance. Don’t let the perfect be an enemy of the good!
By the way, there is an initiative to release the code for all government-made client-side apps in the EU that you can support.
@@vaclavtrpisovsky I didn't mention software without a reason. That's the soul of modern smartphones. And a lot of apps are time-bombed: you can't use them unless you upgrade. And even if your hardware is perfectly functional, you"ll find that it is no longer supported. (Can you link that initiative? I couldn't find it.)
@@atdzsny I cannot paste a link due to the spam policy. Last time I saw it, it was a petition pushed by F-Droid, CCC, Wikipedia, GNU Foundation and others. I cannot find that document but apparently, a project called _GovernSource_ came out of this and also includes backend code such as a unified database system for jurisdictions.
I don't mind the missing electronics, but I am disappointed by the missing cat.
On the way up, the air fills the cylinder as it passes the flexible piston. Where does the batteries go? :-))))
Next: turn single action pump to double action! Patent the method and become rich!
These came stock with LADA 2101
dany, i think you put the pump foot (or whatever its called ) in the wrong way, the original should be the opposite side of the hose
Excellent but... That needs a new rubber
The bigger metal washer sits above the rubber seal and that works to catch air on the way down and allows air to slip by on the way up. The pump actually gets warm from the air pressure and valve friction. And another piece of useless information, it wheezes when you stroke it rapidly.
