BOLTR: Parker Bent Axis Piston Motor | Hydraulic Industrial Lego

100 horsepower in the palm of your hand? Typical Friday night in the Bumblefuck household. Early Access to New Stuff: / ave

[@tjockiskatten]

I'm from Sweden and as soon as you popped that open i recognized the parts. I used to harden those. They are plasma nitrated.

[@arduinoversusevil2025]

Thanks man!

[@tjockiskatten]

AvE No, thank you! It must be about 7 or 8 years since I worked with metal hardening. You just gave me some fond memories.

[@PyroShim]

This is why i still use youtube!

[@MrPruske]

great info can still be found :)

[@Lillebroor]

I worked at Parker too here in Sweden. As a machinist where they produced the hydraulic blocks. =)

[@Afraithe]

Leakage is cooling, gotcha, it's like I say with my old volvo wheel loader from -79, if it's leaking oil, it's got oil.

[@Valtra-rn1ed]

Affra thats what i always say! Start worrying when it stops leaking!

[@aGamblingGoose]

Only way to know if there's oil in it is if there's oil under it.

[@perlandstrom5023]

Yeah no need for a dipstick XD

[@AndersJackson]

And it is good against rust too.

[@mmurola9859]

Someone told me he saw an old Caterpillar wheel loader where instead of the transmission fill plug there was a tap. Each evening the operator would drain several liters of oil from the trans and pour it into the hydraulic tank. He sai "I'll just put it back where it came from". Had a leaking transmission mounted hydraulic pump so the oil came from the hydraulics system. Also heard of a Lännen loader excavator that had a sheet metal pan suspended by chains under it's belly to catch the drips. :)

[@nbrosens]

Ah yes! Another AvE vijeo! Dear Bumblefuck, I leave you with a thoughtful poem.. Mary had a little lamb It ran into a pylon. 10,000 volts went up its ass and turned its wool to nylon

[@altfseven]

nbrosens Mary had a little lamb He farther shot it dead Now she takes it to her school Between 2 chunks of bread

[@steviefordranger198]

LOL, love it.

[@timrobinson9192]

Mary had a little pig She couldn't stop it gruntin' Once it got right on her nerves She kicked it's fucking C**t in !

[@tyttuut]

"It's starting to get a little haggard around the edges." I'd say it's more haggard in the middle, where you poured molten aluminum on it.

[@timothybarney7257]

I was thinking that as well...the edge was the only good part left!

[@nissearkevid1995]

This is the coolest piece of gear you've disassembled ever. Thumbs up!

[@Fredtheswedex]

Biased!

[@martinxXsuto]

The variable displacement pump was also cool

[@Vladimir-hq1ne]

I've seen that piston motor 1st time in my life. And I've lived without that knowledge for 45 years. Pity me. thank you, AvE and whoever sent this motor to disassemble! This is really amazing! Thank ya'll for the enlightenment!

[@Catatonicwater]

New mat = another foundry vijayo

[@jonasnacinovich]

Well fuck, I thought I'd have a cool comment in saying I've been swapping out Parker parts for ten years on various aircraft in Manitoba. But I guess the Swedish dude who plasma nitrated this stuff has me beat. Anyway, thanks to the masked hero who stole the part from work for the sake of this vijayo. Cool shit inside that little gem

[@MattsAwesomeStuff]

A new self-healing cutting mat? Nooo! I used to be able to tell roughly how old a video was by the condition of its battlescars. Now you've gone and destroyed all that precious chronological metadata. You fool. Hopefully her time away from the main bench lets her plastic nanites work their magic and in a few months we'll see her back in competition form.

[@pubcollize]

This one is clearly bigger though. So now we can have an eaven rougher estimation based on which cutting mat is shown. Let them be known as Bigger Cuttingmat and Authentic Deck. AKA B.C and A.D.

[@LucasGarrow]

Like being able to tell what season we're in.

[@MikeCookie1973]

Go back a bit, and you might find when the previous one was put into service...

[@jonathanryals9934]

I'd say one a year is 'bout right.

[@tattmanndann]

MikeCookie1973 here i think .kzbin.info/www/bejne/baGxXpmkisp0adE

[@zadrik1337]

That clean mat is hurting my eyes! Spill some schmoo on it right quick before bad karma finds you... Too late, breaker blew.

[@IchigoKurosaki77]

Good job old mat. You walked the path and passed the trial. You enjoy your retirement on the other bench. *Amazing Grace played by bagpipes*

[@Ariccio123]

Patrick IKNOWKUNGFU *taps* tho

[@IchigoKurosaki77]

Alexander Riccio That works too.

[@Fireholder1]

Red Green, is that you?

[@BlankBrain]

I had a summer job building axles for mobile homes and travel trailers. They modified the assembly line to weld the spindles onto the axles rather than having pre-built axles. Brilliantly, they didn't allow space or time for the axles to cool before assembly. We got pretty good at spitting on the axles to tell how hot they were so we could guess how much to preload the wheel bearings. By the time they got past the leaf spring assembly station, they had cooled enough to be inspected.

[@tbernardi001]

"That's quite a small shaft" If I had a dollar for every time I've heard that.

[@junky5422]

Tell em you'll make it up with the 1200 rippems. Enough friction to boil a kettle in 60 seconds...

[@DrSlay1313]

60 seconds is a long time.

[@timrobinson9192]

I'll second that !

[@russellashburn6268]

For a bit of history, the reason these motors are made in Sweden is because this motor style was invented by Volvo and were bought by Parker. They have been the best motor in the industry for years. These motors are one of the few things that Parker has bought and just left alone because anything they changed would just screw it up.

[@bobsacamano4648]

Actually this motor was a product of VOAC, a collaboration between Volvo and Atlas-Copco. VOAC was bought out by Parker Hannifin

[@pauldavidson6321]

@@bobsacamano4648 it was Volvo before it was voac ,been using them for 30 years now.

[@usquanigo]

"Never force it, just find a bigger hammer" lol!

[@hygrometer]

for years ive been waiting for this day. NEW CUTTING MAT! unbelievable

[@mikebrooka9395]

When I read your post, I said to myself "Self, he has a hydrostatic motor or fixed volume pump with over pressure release." All you need is a variable swash plate pump to make it go backwards or forward in infinite increments. Check out the hydrostatic Eaton units on things like smaller Toro front deck riding mower, self propelled concrete saws, and even the lowly MTD brands of hydrostatic transaxles (Eaton hydrostatic units). Lots of fun to play with and many shop uses. I used them for riding mower racing (hint, if you stress them like I did, sinister 10w40). Take care from Oklahoma, Mike and the old lady that hates my cigars 😎

[@The_sinner_Jim_Whitney]

Damn, that thing is AWESOME! I’ve never seen (or at least never known that I was seeing) one of these. What a cool unit, thanks to whoever sent it, seriously.

[@Bluuplanet]

I have an old transmission from a WWII bomb bay door that contains two of these bent angle piston thingys. One is a motor at a fixed angle like this one. The other, in the same cast aluminum case is a variable angle piston pump. Since it's variable angle, an angle gear around the perimeter of the 5-shooter cylinder wouldn't work, instead, there's a CV driveshaft through the center. the angle is adjustable with a lever outside the case. It goes from zero degrees (where the output shaft doesn't move) up to an angle equal to the output bent angle (where the output shaft rotates at the same speed as the input). It was all fastened together with wired screws. I took it apart years ago and couldn't figure out how to get the parts back together. Its in my garage in a plastic bag and a coffee can of oil.

[@SecondLifeDesigner]

A lot of the stuff in the video goes over my head but I so enjoy the process and narration and usually end up learning a thing or two. :)

[@BruiserBob]

I couldn't be prouder than I am being a patreon of this channel. Every AvE video gives me nothing but joy. Cool as hell as always man!

[@stuffyours]

Best video ive seen of yours yet sir! Very cool piece and so interesting how that damn thing works.

[@oscarwitte493]

Covered these pumps two days ago in aviation maintenance school. Perfect timing, thank you!

[@sirthicenskoorb3684]

I don't understand the technical jargon but love the colorful jargon. My grandparents raised my aunts in Canada. One aunt used old sayings. What a card. I always watch your videos.

[@luisvillalobos6517]

What a beautifully designed and built piece. Good lordy. Such a beaut

[@jimallen1485]

Does your shop look like the rest of your bench? My shop and bench are a clutter disaster. My wife wants me to clean it up. I told her I was waiting for the appraiser so I could stick a 2 million dollar price tag on it and sell it as modern art.

[@VictorGarciaR]

I bought another workwench, lighter duty. Now all the crap is on there

[@christinamichelle2830]

The only answer is to build a bigger bench.

[@jaronbernard9911]

I built 2 work benches, albeit from dead tree carcass, but at least it’s cypress right

[@glenralph5123]

Awesome motor and vid, cheers! Back to Chris at Clickspring.... cheers for that hot little tip too, brother!

[@TriccyViccy]

"100 horsepower in your hand"? That's what I brag about in regards to my... Drill. Also, RIP cutting mat. You will be remembered O7

[@ThriftStoreHacker]

Wow. What an amazing bit of equipment AND a fancy new mat! Living the dream.

[@TheWisehydralisk]

Wanted say that I was teaching my trainee at work how to torque a cylinder head. I used your method of a grunt and a click. He kinda of gave me a clueless look then proceeded to torque the rest of the head that way. Took me 20 minutes of explaining how to actually torque some thing and the importance of it. Thank god it was a junk engine that he was practicing on. As always love the vids you basically mirror my personality.

[@TheJustin574]

I had a smile on my face when you said 100HP, that was my guess!

[@budude2]

Even though I've heard it a hundred times and even though I know it's coming, I still giggle like a little girl when you blurt out the 'ol 'give it a little tappy-tappy-tap-tap'...

[@damedog19]

It's the little things in life

[@n1r0lanynonmouse6]

What is amazing is watching other videos of guys working on cars, machines, etc. and hearing them say the same thing. "Aha, another cult member! Welcome"

[@steve1978ger]

... what's that about anyway, sounds like he is channeling Chef John or something.

[@jamesmccabe103]

"Worse than java" I lost it man, Keep up the good work!

[@mysock351C]

The machining looks like what you'd see in a car transmission. Very nice and the taper rollers look more like bearings for a rear end. Must be under a lot of load, for sure.

[@Steevo69]

The shaft got etched (scale prevention) during processing to ensure no cracks/surface flaws formed during or from the drop forging, milling, or heat treatment process after, the bearing race, the only "to tolerance" fits were machined after heat treatment and the whole part then probably underwent a final surface hardening, the threads were rolled on directly after forging.

[@MrSheaonemillion]

Thank you very much for all the weird machines and great explanations!

[@Smikkelboy69]

Its awesome to see such nicely made tools. Thank you for another great video :)

[@GasNBullets]

Ok Time to build a hydraulic gokart!

[@233kosta]

Sign me up! I'll do the gas turbine driven pump!

[@John_Ridley]

Fantastic! I love finding out about new ingenious stuff that has been invented.

[@stalkinghawk9244]

AVE, I have to thank you for showing all these things, besides your VFD COmpressor video inspired me, Right now I've gone full Canadian and I´m in the middle of running my 3kw compressor on a VFD and PLC combo to automate stuff. I already have plans(and working examples on drawers) for automatic pneumatic doors. In the summer ill take on a hydraulic project.

[@PsiCommando]

I like how you keep your workbench nice and tidy :D

[@obscenitron]

I give it a week... and it'll match the last one.

[@thomas316]

"Double lip seal" Am I awake right now? 🤔 I didn't know I had a preference for seals but it turns out I now have a favourite. 😄

[@austinJRu]

Awesome man. Diggin the hydraulic stuff. Thanks for sharing.

[@docking_bay_94]

Thanks for the stickers. Very cool. They are the very first adornments for my very new and also very first tool chest.

[@Ace1Of1All1Spades]

As a millwright apprentice I appreciate the shout-out. Also I love my learner hammers and brass rods 😁

[@cubby612]

The lines on the old mat were finally worn enough to allow the camera to focus on the subject. Perfect.

[@WoodWorkLIFE]

Japanese woodworking hand tools are awesome as well, there are scammers out there all over the place capitalizing on Japanese maker and brand names, but the antique stuff is amazing. Keep up the awesome vids, you are the uncle bumblefuck I always wish I had...

[@TySoVm]

Brought back flashbacks to rebuilding my ford 8.8 diff, getting those carrier bearings off nearly killed me.

[@anthonyblacker8471]

I worked for Parker Hannifin when i was in school.. it was a small shop, we made hydraulic fittings and some small pump machines.. it was a neat place

[@raysplace6548]

The best vids on KZbin.. Good stuff man.

[@georgebonney90]

Cant tell u how much i appreciate the share of knowledge

[@ninney794]

I fucking love your vijayos! Such a wealth of knowledge you hold! Reminds me of my grandfather, I'd like to know half of what he had forgotten over the years haha.

[@dylangray1579]

ive done hydraulic pump repair for years. just recently got a job at parker hannifin in the hydraulic pump division

[@rimmersbryggeri]

We make alot of industrial stuff in sweden. When I made haldex parts we had UNC UNF NPT and metric within the same part. Pipe fittings are often sold as metric these days but they are all compatible with BSP threads whether they are cylindrical or tapered. At least the ones I have used.

[@HamiltonSRink]

Very Cool Video! BTW, I really enjoyed the Christmas story !

[@dumbbuck]

This is a similar mechanism to how a Karcher 3600psi pressure sprayer works, just in reverse. The petrol motor drives the input shaft. That has an off axis plate that pushes 5 pistons back and forth as it rotates to boost the pressure of the fluid giving you high pressure fun.

[@jonathanhigginbotham6964]

I have watched for about 5 months and seen most of your videos but I'm lost as to what AvE stands for? Love your stuff keep it up ☝

[@Leffe192]

Arduinos versus evil... Goes way back, he has shifted focus slightly since.

[@jonathanhigginbotham6964]

Thank you ive been wondering for ever, he inspired me to start a channel again. Wish there were more people like him.

[@Meepster12]

So good to see that I'm not the only one struggling in the shop!

[@UPrider988]

@AvE, take a look at parker hydraulic hybrid transmissions. They used to use a pump that varied displacement all the way to a negative value to make it a motor as well. Really cool technology that never took off.

[@awptickes]

This audio is a lot better than the "dude gets charged with felony video." Whatever you did in this one, keep doing it.

[@CMDRunematti]

love those, pulled one apart once, from a friction welding machine, they can do 18k rpm (seen them hit 26k)

[@SpoiledBadgerMilk]

I am no engineer. But mIwatch all your videos. Lol I love watching things get taken apart. I learn allot any how great video keep it up.

[@tyler1h23]

I just want to say that I absolutely LOVE your videos!!! I literally watch at least 2-4 a day if I can help it and have the free time. The depth in which you break each piece down and explain what you're seeing is just plain fucking fantastic. LOVE IT MAN!! But also. What ANDROID borescope are you using and where did you pick it up from?

[@superdude123032]

New cutting mat. Time to celebrate boys. I’ve got that same hex key set. Bought a couple of sets on sale at Menards.

[@gabbermaikel]

nice to see a reliable source for the android bore scope video quality. Was looking to buy 1 this week, but wasnt sure about the quality. Have been using the borescope from my work, but well its kind of expensive, and i dont want to ruin expensive tools i borrow from my work at home.

[@michaelbohanon8137]

End of an erra. RIP old OLFA mat. Thanks for the excellent TGIF fodder and..I just got a scope like that for my Android too. Crazy cool eh!! Keep up the keeping up Bumblefook!

[@rynohorn3819]

Only understand half of what you're saying but I enjoy the show. Thanks AvE

[@allanwilson8642]

I understood very little of the technical content but privileged to witness the advent of new cutting mat day.

Had some good laughs at this one! More FPM’s than usual...sounds like me in my shop...

[@desertforgeknifetool2142]

Your channel is awesome!

[@LTdesign13]

That's probably one of the coolest functioning motors I've ever seen.

[@whereiseshan]

this type of motor is commonly used for hydro static drive motors in vehicles, hydraulic pump driven by engine will force hydraulic fluid into motor which you have to turn the wheels...pretty awesome stuff

[@marcjordan29]

Loving the "tappy taep taep"...... And the 5/8ths SHAFT

[@curtjrich15]

I like olfa products aswell. I just recieved thier newest knife in the mail, excited to check it out when i get home. Model LA-X, with an autolock, and an all purpose pick for opening paint cans/prying small things.

[@Slowpoke5055]

I have learned something today. Thank You

[@matthunter2952]

O-ring boss comes in metric too. Closed circuit pumps have same size system ports. But they do mix sae and metric fasteners and ports on the same pump/motor. You're right though they are skookum as frig. I abuse them daily.

[@dylanheadrick3789]

Those piston sealing rings on the pushrods look incredibly similar to the gas rings on the rear of an ar-15 bolt. They use 3 steel rings to seal against the interior of the bolt carrier to allow gas pressure to unlock the bolt face from the chamber.

[@jackcaldwell485]

I still can hear you do " happy tap tap, and finding a hair and gagging" 😂😂

[@scottsarchitecturehildebra1761]

Amazing, a fantastic upgrade!!! Sooooo dig the speak!!!

[@ricknelson7824]

Actually it used to be branded Volvo bent axial piston motor. Looks like a c10 version designed for around 12 gpm at max 2200 psi. Horsepower would be more like 25-20 hp. Generally rpm as a fan drive was 5000 rpm. They can spin faster but at a cost in longevity. Biggest problem was if case drain was restricted and not free flow to tank. Lip seal on shaft would fail.

[@donttreadonme7630]

bravo... back in the ice age my college hydraulics class would have benefited from this video greatly.

[@danethibodeaux9892]

I work on these for a living. We supply Parker. That's a fixed displacement motor. Good product

[@bevanharding1160]

Beautiful piece of gear.

[@porklaser]

I got that same cutting mat for my workbench! Love it to death, but brand new it out gassed and stunk up the room for a few weeks after I got it. Olfa suggests washing it down with dilute vinegar to reduce the smell when it's new.

[@legendaryrat]

Let us have a moment of silence for the old cuttin mat.

[@canningpark]

LoL I had a good laughter when everything starts to goes wrong!😂✌

[@jokker03]

8:14 "I'll loosen this nut off and we'll explode..." see this is my favorite part of these vids, making complex gear relatable to a dumb schlub like myself.

[@pubcollize]

That paintjob is so thick I would've said they outta be hiding something. But it looks so damn perfect on the insides, gotta believe in em.

[@petergriffin383]

AvE makes me piss my pants laughing almost every time..."for fucks sake!, it doesn't end boys...it...just...doesn't....end"

[@richardshortman5645]

Knipex! One of the most useful tools out there. That and a screwdriver and DMV would fix half of all the stuff in the plants.

[@reillyc7605]

There are specific torque specs. For the lock nut depending on the size of bearing. There is even a chart for how many degrees you need to turn the lock nut if you can not measure torque.

[@TheRayneForest]

That is some wicked stuff

[@benwinckler131]

Those metal things are shims and they are there to evenly space the gears to give variable gear backlash cause those things spin at 3100 rpm (hey i wrote this halfway through so 3100 was a geuss until I watched it all) and as they need rebuilds the gear teeth wear and need to be closer in backlash There is a lumber yard with two of these and it is a saur danfoss with 1 inch pistons (8 of them) to drive an 8 foot sawblade

[@EvelioPerez]

new cutting mat! it was about time!
