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
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. :)
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.
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.
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!
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
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.
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.
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.
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.
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.
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.
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 😎
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.
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'...
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"
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.
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.
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.
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...
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?
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.
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!
@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.
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.
I love watching this beceause im doing hydraulics in my heavy equipment service tech course and i can appreciate your videos so much more it just makes this shit cooler!! Love the content much love from NB Canadurp
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.
I don't know if I've just had too many Scotch libations; however, I think this was one of your funniest videos. I love watching you fuck around in the shop. Keep up the bumblefuckery. *Stickers/t-shirts appreciated.
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.
It's amazing!?! You do a fabulous tear down, and the majority of Commentards (affectionately known at "the register".com) are most interested in the damn cutting mat 😁
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
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.
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.
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.
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.
A mistake I caught was that you said the pistons are pushed back due to the pressure of the oil. But the oil is at tank pressure upon intake. The pump if used on a large truck like a wrecker it would run off a PTO. That means the oil is being sucked in then pressured on the compression or exhaust stroke. Idk what it would be called on a hydraulic pump. I love the videos man.
Fun fact, this is probably built here in little Trollhättan, next to GKN (old volvo aero) which makes jet engines for SAAB technologies and a lot of other stuff including rocket parts. Next door again is the SAAB Automobile factory which now houses NEVS.
