WHAT MAKES IT WORK? #17 pt 1 of 2 "How a Hydraulic Jack Works" tubalcain

In this 2 part video, I disassemble a bottle jack, and show how it works.
Watch all the videos in this HOW IT WORKS series.

[@Cheepshooter14]

Mr Pete, you are a real treasure. KZbin, the internet in general, and our US educational system sure needs more like you.

[@charlesonyango5608]

Amen to that!!

[@nbrakhage]

Tubalcain is a wealth of information. In my opinion he's a national treasure. I hope somebody is archiving these videos for future generations to benefit from.

As Peter Crenshaw, from the Three Investigators, would say:” I’ll buy a double helping of that”

[@fomoco1454]

Brings back memories. My grandfather who was born in 1924 bought a lot of tools from Montgomery Ward including an old style rear engine riding mower. He loved M.W. and Sears and would use any excuse to go there. Great video Mr.Lyle, thanks!

[@MrSamBowers]

This is actually one of the better videos of jack repair on KZbin that I have seen.

[@mrpete222]

Thank you very much

[@EmmaRitson]

these videos are very useful, Mr Pete. keep them coming. learnt lots.

[@neilsbergstedt]

What Makes It Work is my favorite series of yours. Rebuilding a jack is on my list of things to do so I was pretty excited to see this video. Thanks!

[@breezyweasel]

I absolutely loved this video. Very good explanation, enjoyable narration as far as content, thoroughness and style. It's as if an engineer and a mechanic had a baby who was given up for adoption and raised by Walter Cronkite and had the best qualities of all of them. Thank you for doing these videos!

[@mrpete222]

Thank you very much, you put a smile on my face

[@kklein1240]

You sir are a wealth of knowledge! I have only just discovered your channel, to see about repairing a bottle jack project with my kids. I can't wait to sift through these videos. Like listening to my late father-in-law's wisdom on general tools and how they work. Thank you for making these videos!

[@TupperWallace]

I always wondered exactly how these things work. Thanks for doing this series.

[@citec123x]

This video should've been titled... **"How a Jack Works FOR DUMMIES DUMMIES(double dummies intended)"** there is no way that even the most thickest headed dude would not understand how these gentleman explained it. Great Job SIR... !!

[@mrpete222]

Thanks

[@fiddlerpin]

Enjoyed the video. Now I know how how it works. He could be the next Mr. Wizard on TV!

Finally a video from someone who actually knows what they are talking about.

[@Colorado1272]

Absolutely love that you take the time to produce these videos. I hope there are kids out there watching and learning what it is to be a man.

[@mrpete222]

Thank you, I'm glad you like them

Great explanation. Many thanks for your tuition from the UK

[@johnrine9671]

I really enjoyed this set of videos.thanks very much.

[@terryjennings2356]

Wonderful video!! Thank you for going so far in depth!!!

[@jimenglish1981]

Very thorough and well explanation! Thanks!!

[@spp-wv2ob]

What timing! Been wondering how the jack was put together and now I know. Matter of fact, watched it twice and am going to change the jack oil to see if I can get the jack to raise a bit higher AND to see if any water has contaminated the jack oil that has been in it since Methusala was a tyke! ALWAYS watching your videos to the very end since you are super thorough and leave nothing to the imagination ... plain and simple! Thank you, John

[@bobcriss600]

Pretty neat way to show the passages! Thanks for thinking of it.

[@mrpete222]

[@MaturePatriot]

Another entertaining and educational vijeo. I like how the ENGINEERS increase production by doing things that no one who actually uses the product would do. Saved a penny, got a bonus!!

[@springwoodcottage4248]

Splendid! My first hydraulic Jack replaced a mechanical screw Jack operated by 1/2 inch square rod, easy to knock over and hard to operate. Hydraulic Jack transformational, till they, as you noted, removed most of the jackable points, so now back to screw scissors Jack that is great till jacking point corrodes. Find keeping newer cars running is much harder than older ones.

[@sprtjnke]

Thanks for the cool lesson. Is on to part two!

[@Kalkaekie]

Very well explained !

[@caseygribben4038]

You are providing some vital information for my 3rd year university engineering project. Thank you for your investigation and your insight!

[@mrpete222]

👍👍

[@Kris_at_WhiteOaksFarm]

That was fun and informative. Thank you.

[@beesdreams9]

Thank you for this. Grateful for your skillfulness with teaching. I now know the problem with my jack. The ball bearing blew out when my girlfriend accidentally removed the bleeder valve and then I made the mistake of compressing the ram (to free up the jack from beneath the car) before screwing the bleeder back in. Must have spit it out roadside in Death Valley. (Took an old pushrod through my tire!) Live and learn!!!

[@toddanonymous5295]

Mr Pete, As with all good teachers you make learning both interesting and fun. That must have come in handy over your career teaching young short attention spans. I had an industrial arts teacher years ago who you remind me of. I still remember his interesting demonstrations. Thanks again for sharing your vast knowledge. Hope you never retire from your second career.

[@quenemoend]

I tried to get into shop classes but they would not let us girls in at that time. I HAD to take home economics instead. 🤬

[@cox315]

thanks for taking the time to make the video, found it very informative and interesting,

[@iwannarule97]

Thank you sir. Much easier to fix things when you know how they work.

[@hennievanderwesthuizen1223]

I remember that when the bottle jack was lowered and the clearance under the vehicle became very shallow it was very easy to drag the jack out with the jackhandle because it slotted perfectly into the pinned valve. It also did not slip of when you opened or closed the valve. Those were the days.

[@sharonfoster1845]

I found a big gigantic bottle jack had no idea how to get it to work I've been able to fix floor jacks but not a bottle jack this video is one of the best videos I've ever seen very well done very well executed I love it gentleman is very well spoken thank you very much for this I appreciate it definition of striving and hope you got more videos for different things

[@mrpete222]

Thank you very much, I’m glad you like the video. I really worked hard on making that one

[@glenjackson2840]

Yo! Thanks you for this video. I like allot of your videos. You'd be a good professor.

[@junkmannoparts9696]

Hi Mr Pete I'm glad I'm watching this video i have a old 20 ton from before there was HF stores . i got it from a import tool store i think its made in Taiwan and all the impact sockets i bought are made in Taiwan very good . back to the jack about 5 years ago it quit working and i am hopping that i can remove the check ball valve assy. out and try to fix it . Thanks JM

[@mrpete222]

👍👍

[@guerd87]

I regularly rebuild pumps at work that are used for trailer and caravan jockey wheels, called a trail-a-mate if you want to check them out. Only difference, like you mention, is the power piston i will call it, comes out the bottom and is alot longer. Very simple design but very effective. great video :)

[@patsullivan9399]

I worked for a while in a hydraulics repair shop, and one thing I learned that should be mentioned is to NEVER use brake fluid in a jack... it will turn the seals to mush.

[@jaredj631]

Well thanks that is helpful to me. I will fight the temptation next time

[@TheNewenglandboys]

That's BS.First thing I do with hydrolic jacks is drain out the fluid and replace with brake fluid! And I've got a 6 ton bottle jack from 1980 still works flawlessly! Why do I use brake fluid? Have you ever tried using a hydralic jack thats been in your garage during freezing weather? Pump and pump and nothing happens because the fluid thickens rendering the jack useless. Your brakes still work in your car don't they? Of course. Brake fluid is hydralic fluid more refined. Thats all. Not going to do a thing to the seals in that jack. Brake fluid is more expensive but thats why.

[@applepoop10]

Can you use transmission fluid also?

[@patsullivan9399]

@@applepoop10 Not recomended, but if you really need the jack working and that's all you have.

[@ramonarroyo5573]

Awesome job thank you very much

[@69adrummer]

Great stuff! You young "men" with your v-necks and your latte's and VW Golfs and I-phones can learn something from this guy! One look at the hands tells you all you need to know! How a Torque Wrench works would be skookum!!

[@spettro9]

Thank you for making me feel I'm not too crazy, as my thought processes as I repair/rebuild/inspect/do all kinds of projects sound quite similar to yours, down to the reservoiahhhhhh Except yours is in a soothing Chicagese, and mine is in cynical Jersey. Your videos are great!

[@mrpete222]

Thank you very much

[@juanrivero8]

One thing to add about (incompressible) hydraulics is that pressure x area is constant. Hence, small pressure on big area = large pressure on small area. And vice versa. So, since we humans can only exert so much pressure, we use the relative areas as a force multiplier, and are able to raise a two-ton car with a one-foot lever.

[@Lazywatchsmith]

very interesting. thanks.

[@Sir_Leelord]

This video is gold. Subbed

[@jayjohnson5077]

I found exactly what I needed to know from watching your video. Have you tried heating the base of the part you had trouble taking apart. The reason is that the manufacturer probably used red locktite which would be required under the UL testing rules. This product will actually etch the metals together the same as what happens in a disc brake bolts as a requirement for safety ect. And sometimes will actually destroy the two parts if unsealed.

[@MegaChekov]

Thanks sharing That Pascale was a very interesting guy for his time

[@mrjohnnydrinkard322]

hello, love the videos. .i was browsing through and stopped for this. i just bought a long ram for a shop crane build im working on. A tip to remove tubing without crushing it is , clean out , fill with play sand ,duck tape the top and seal , then clamp away . This also lets you bend as you please without crushing ....its amazing

[@mrpete222]

Great idea--I have done that with copper tubing.

[@kevinwillis9126]

thank you sir for sharing.. interesting as always...

[@pthumphries1]

I just came across a 20t hydraulic ram style steel bender this afternoon in the work shed, and was wondering how to fix it. Honestly, you've made the complicated simple. Thankyou. Guess why I wanted to use it? I have a tennis court, where a herd of cows went running through, and bent the pipes. Last ditch effort to salvage it before scrapping it.

[@mrpete222]

👍👍

[@edflower109]

Hey Mr. Pete I have a thought on how to get that stubborn part off?.... Could you bore out a piece of metal to the OD of the piece you want to remove . cut a kerf length wise . Press it on . and then use the pipe wrench ?

[@Bluuplanet]

That plug screw is one of the few applications where I can imagine using a hammer drill (not an impact driver) to put the screw in in the factory. It would set the taper in place snugly and the threads holding it in place would be secondary.

[@FretsNirvana]

Another great tutorial. I have a question about maybe modifying a hand pump bottle jack to work off of an external hydraulic pump of sorts ...maybe an air hydraulic pump. Could you drain the oil on the bottle jack and tap in at the pressure release point of the jack. The hydraulic reservoir from the pump then is used for the fluid etc. This is how porta power pumps work I think. Your thoughts if you have the time. I know the PSI has to be taken into consideration as well but in the theory would this not work?

[@imthemistermaster]

you remind me of my grandfather, and that makes sense because he was a heavy machinery mechanic. you too even sound similar

[@mrpete222]

Thanks

[@scootyman2974]

imthemistermaster actually he sounds like the Grandfather I would have wanted. I love videos like these. Subscribed!

[@cepolt]

I agree with both of these two comments! Almost sounds like my father's generation. He fought in the second world war and grew up in NYC. Became an engineer after. Something in your voice; they just don't make em like they made you anymore unfortunately. Or at the very least, you're a rare breed now these days.

[@chocolate_squiggle]

This is awesome, thanks. I unscrewed the valve on my trolley jack just a little too much and a small amount of fluid escaped. I've been a bit wary about that jack since, I didn't know if I'd compromised it in any serious way. Now I can understand it's not going to suddenly collapse because it lost a tiny amount of oil from the low pressure reservoir. It probably just won't lift as high as it did before. Thanks for taking the time to show this stuff. Good health to you.

[@patcb829]

Nice to know I'm not the only lunatic that welds those handles together.

[@Cheepshooter14]

or replace it with a piece of galvanized pipe with one end smashed!

[@levinorthover5727]

There is still newer ones with the pin instead of the flattend ones I like the pin ones with the slot in the handle better used them alot setting up twelve wide before . then we switched to the rubber airbag Jacks there awesome ever seen them ?

[@BottleJackBuddy]

Great video!

[@mrpete222]

Thanks

[@seshachary5580]

very nice explanation thank you regards

[@polarys425]

The ball on the end of the pumping piston provides a stop in order to prevent the seal from being crushed or damaged.

[@MattSeals]

Great looking video content. Assume you did a great deal of your very own coding.

[@BrotherWitch]

If you take a look at a common floor jack, there is a bottle jack laying horizontally providing the force.

[@mrpete222]

+Jason Moonsmith So true-I should have mentioned that

[@maggylevesque-lavoie7273]

Wonderful QUIET !

[@desalvo66]

i want to thread a piece of steel round bar on top.. and use the bottle jack as a column for a drill press..is it a buttress thread used..?? i can find very little on the web.. and find very little on buttress thread taps and what size drill bit i would need.. can't find any charts.. any of u care to expound..

[@Bluuplanet]

The pad doesn't need a swivel like a C-clamp. C-clamps rotate under pressure. The bottle jack is adjusted before pressure is applied.

[@tpcoachfix]

Great video, very informative as usual, however I would like to point two things. 1. When adding oil to the jack always have the ram/piston in the fully down/retracted position, if not you will overfill the jack. 2. After you lift the car to where you want it ALWAYS put safety stands under the car, in the proper place. NEVER get under the car with just the jack holding it up, if it slips out of place R.I.P.

[@jamesstafford9067]

Mr Pete, can you please do a video on refilling a floor jack? Someone pulled my whole hand out and lost all my fluid. I'd like to fix it and not have to spend $150 on a new one since this is only 6 months old. Thanks for the video and I just subscribed to your channel. Happy New Year

[@aserta]

I think the round end might be to keep the cup in place? It's exactly the same as in some modern pocket sized bicycle pumps. It's cheaper than making a thread.

[@MaturePatriot]

aserta - Easier to slip the cup over a rounded ball for installation without tearing.

[@bluemoonhawkins9092]

You obviously must be or have been a mechanical engineer in your career. You explained it is an engineer would’ve explained it great job!

[@brmelectric]

[@mrpete222]

+Brian Moore thanks

[@Ntwadumela1]

8:25 In fact, when pumping, oil flows from the reservoir to the cylinder which creates vacuum in the reservoir. That's why you leave some air in the reservoir. 12:38 These valves operate by pressure/underpressure and oil flow not gravity. People modify these bottle jacks so that they can work in the reverse position. The pump and valves do not require any modifications. 17:55 The copper wire does not show the passage to the cylinder, which must exist, otherwise the oil could not flow from the cylinder to the reservoir.

[@taylormick4374]

My old jack still has the pin style valve

[@alexduke5402]

We had a loaded tractor trailer full of grain i believe it was wheat. We noticed it had a flat tire of the bead so we had to jack it up. I grabbed a 6x6 and a an 8x8 to get our 50 ton jack under it. I didn't realize it but other guy had let the air out of the airbags. That meant instead of spreading out the load between the axles because it has an equalizer i was trying to jack up the whole 35 ton load. so while i was jacking i was hearing wood crack. And it wasn't going up when i looked under there (it is air over hydraulic) those blocks were completely unrecognizable haha! Use steel blocks when jacking up heavy loads.

Can you give me the brand or manufacture of the jack you used in this video. I am working on a long ram 8 ton it has the same parts as yours just larger diameters. My name plate is faded but I can read a model # 339 and made in Taiwan. It is the same color as yours.

[@alaska3333]

I am surprised to see that the neoprene cup at the end of the piston is capable to withstand all that pressure without breaking or leaking the oil through.

[@sparkmencer]

Thank you, Pete. As always, and I DO mean always, I enjoyed every particle of your presentation. My only lament is that, although you mentioned the need to bleed, you didn't demonstrate HOW to bleed a jack, which would have been the icing on the cake. Mark in Modesto

[@experiencingtechnicaldiffi5184]

+Mark Spencer Most hyd jacks have a bleed port at the top of the cylinder to bleed the air out and prevent over extending the ram. To bleed, just pump a few strokes after reaching the top. If it doesn't have a port then just extend the ram, turn the jack upside down, open valve and collapse it. Mike (o\!/o)

[@sparkmencer]

Thank you,
