and Thank you AVE for being fuckin awesome!

[@travisgaither3078]

Ave... hey man I rebuild electric motors and gearboxes for a living and I'm having a hard time wrapping my head around the fact that you just pulled the bearing off bare handed. whereas on gearboxes they are a press fit. how does the surface not wear?

[@bulruq]

30 years ago I worked in a factory that made compact versions of these originally designed to control gun turrets on bombers during WW2. They also built a brilliant variation called a "back to back piston pump/piston motor". It placed two of these units back to back on a single fixture so that the oil output from the first pump, which is driven by the power input shaft, flows directly into the second pump. This flow then drives the second identical pump and makes it act as a hydraulic motor. You get a compact unit with no external hoses or lines that can be controlled by a simple handle connected to the axis of the swash plate. It also acts as a variable speed, reversible transmission, all with just one mechanical control (a STICK!) connected perpendicular to the axis of the swash plate.

[@MrGimli2]

Well that's interesting as fuck

[@martinda7446]

Haha, I thought so.

[@KimberlyRPeacock]

That is interesting, please share more details and examples if you can.

[@danburch9989]

That's how a hyrdrostatic transmission works on many lawn and garden tractors. With one on each wheel, you can literally turn on a dime..

[@jurekdekarski2316]

bulruq That's pretty cool, especially the bomber turrets part, I guess they were steered with pedals (right and left), I have to dig a bit for more details.

[@delciotto]

Anyone else love just how perfect everything inside hydraulic powered things fit together when he takes this stuff apart?

[@ReverendTed]

I was trying to picture how the fluid got into each piston. I had to think about it for a minute to realize the (possibly self-evident) fact that as it's rotating, the pistons are on their intake stroke over the inlet and vice versa. Really looking forward to the "hydraulic computer" vid.

[@davidlawrence6885]

Yeah, as the cylinder rotates and pistons follow the swash plate, they move down as they cross the inlet creating a vacuum effect that draws fluid into the cylinder and then push up as the rise on the outlet side creating pressure that forces fluid out of the cylinder

[@Scubadiver735]

When your hydraulics teacher uses this video in you class. Gotta love it Aircraft maintenance and avionics at canadore!

[@Carstuff111]

This video just made my night, thank you :) I knew how that kind of pump worked for years, but see one being torn apart, gives me new understanding and a greater appreciation for the work that goes into making them.

[@DEBOSSGARAGE]

I have rebuilt a couple of hydrostats. One was for a lawnmower, and one was for a skid steer. Both were fixed by taking the bronze plate to a shop to get machined. The shop in town makes satellite parts for Bell. Using their fancy computers they machined it level to .0004" . They charged me $75. If there is any wear in the plate, the oil will leak off and go to sump. I have never had any other issues with the hydrostats (pistons, swash plate or whatever). 98% of the time it is that plate

[@Foxboss9]

all the hydrostats from transgear that I have done can be brought back to their former Glory by getting rid of the crappy lightweight gear oil they were shipped with at the same time micropolishing the plates on both motors and cylinders with a random orbital palm sander.. works like a charm😀

[@rogerbrandt6678]

Do you mean .004? Because to get something down too .0004 that's amazing.

[@DEBOSSGARAGE]

+roger brandt yes I meant .0004. they measure it with a Lazer somehow. the technology is here...

[@rogerbrandt6678]

+DEBOSS GARAGE wow that's impressive I Run a Cnc lathe and can make adjustments to .0001, but never no need to go that low, what kinds machine do they use.?

[@DEBOSSGARAGE]

+roger brandt no idea. I have a channel too. if I run I to it again, I will definately make a video though

[@steamboat1341]

I was studying the axial pump on my john deere tractor and your video helped tremendously, thankyou so much will continue watching. Take care.

[@davidcoghill8612]

A thing of beauty. Fun fact: Back in the early days of jet engines, these were used as fuel pumps. The advantage of these is that the full capacity of the pump is only needed at take off, only a fraction of that fuel needs to be pumped to the engine during the rest of the flight. If you use a gear pump, from take-off to landing it has to pump at 100% of its capacity, which means you have to let most of it drain back into the tank, this has drawbacks such as heating up the fuel that's not being used, over and over and over again. As jet engines got bigger, piston pumps fell out of use. To get a higher flow, you can either run it faster or make it bigger. Bigger was no good because the size and weight of the pump needed became prohibitive. Faster was no good because no bearing materials exist which can survive for long in those conditions (remember these are pumping jet fuel, the lubricity is much lower than hydraulic fluid). On the other hand making a compact and high capacity gear pump is fairly straightforward, the only bearings you have to worry about are your sealing faces which are taking barely any load.

[@rogerbosman6518]

those variable displacement pumps are still in use on airplanes to keep hydraulic pressures at 3000psi. They seldom cause problems.

[@ryallmackcowling]

This is such a throwback for me, I used to work for a company that made hydraulic pumps JUST like this one. Usually I have basic knowledge of how stuff works when you tear them down, but this one... I followed along and could actually know what you were going to extract next. Awesome shit man :)

[@Recovering_Californian]

100 HP in my hand every time I shower.

[@MerpSquirrel]

Until you release the Schmoo, then there is no point in pumping the piston any longer since increased pressure will not provide increased flow.

[@infoanorexic]

Thank you. This has removed a major amount of fuzz from my understanding on how these pumps/motors work. Keep that razor sharp.

[@xcofcd]

This kind of design is relatively common, from the AC compressor in your car to a fuelpump on a 1950s jet engine...

[@acammer]

Exact same type of pump that you find in an older (read good - overbuilt by factors in the 10-20x) hydrostatic drive tractors. I have a 1972 Cub Cadet 149 that uses this exact same type of pump - the infinite variability allows you to extract maximum torque to speed. My application was tractor pulls, a hydrostatic drive allowed you to set the engine to full governed speed and then vary what amounts to your final drive ratios as needed - full speed ahead and the start and then as you start to run out of power you pull back on the output to reduce the load against the engine driving the pump - same effect as gearing down but without any disruption in power. Love this channel!

when?

[@lacarpetronpinkerton9114]

You are my favorite channel. Every vid is a treat, thank you.

[@GearHead4Lyfe]

The torque these things produce is crazy. I have a diesel Deer garden tractor that uses three of these variable displacement axial pumps, one in the back and two in the front (AWD) and they run the two in the front coupled to the steering to adjust the wheel speed independently so it doesn't scrub in turns. Granted there is also gearing involved with the back axial pump but it's a powerhouse for sure. Very cool stuff!

[@tny-]

pretty amusing and totally makes sense to me that they can handle serious torque, cause those tapered bearings are real similar looking in size to trunnion and wheel bearings on (toyota) pickup axles. the shaft also looks awful similar to the input and output shafts on their transfer cases that are pretty well known for how much torque they can handle under gear reduction. impressive hunk of steel there.

[@itsgalf]

And the great thing is that the same device is also used as a hydraulic MOTOR when the flow instead pushes the pistons through the cylinders. Hydraulic systems are pretty interesting. I remember taking one of these apart since hydraulic winches on ships use them. I never knew about the holes in the slippers/shoes that allow hydraulic fluid to form a film between the slippers and the plate. Great info

[@christiangeiselmann]

I know this is not the place for lenghty considerations on sociological topics, but having a lot of experience in South Eastern Europe (where most Roma live) I want to say that it is not "the Roma" who are the problem. Many Roma families are well integrated, quite normal citizens of where they live. The issue is, as an outsider, you do not get aware of those. You get specifically aware of those who display inacceptable behaviour, e.g. pickpocketing or organised begging. Again, those that you see are at the lowest level of organised crime hierarchies, they are victims themselves, usually being forced by their big bosses to do what they do. But again, there are many Roma who live a decent live by the standards of overall society. - B.t.w. when you put out that silicone ring with your sharp needle, I really whinced, knowing what would happen...

[@christiangeiselmann]

Those obviously were the not so well integrated ones. May I ask, in what city did this happen? In day time? Night? Did you complain to the police? (Because that was a proper felony then, not a minor case.)
