Dear AvE, your videos have kept me interested in engineering and thus lead me to my degree. You are just the best. Thanks for putting all the work you do into these videos, man!
Love these vids. I'm not a mechanical engineer or anything (just a web app developer), but I love watching technical stuff and learning. I work on my track car, so I guess this sorta falls in line with it. You're seriously the first YTer I'd consider giving to on Patreon.
I'm in first year HET and we just started taking little hydraulic pumps apart last week to measure the displacement and whatever, good timing for this video! Also, I think that's cool that you can flip the input shaft around in case your pump needs to be driven the other way.
I like the cavitation talk. Ive seen the end results of water cavitating a diesel injection pump quite a few times. They love to send steel glitter all through the fuel system as the pump detonates slowly.
Got a university report on gear pumps and was getting bored of my tutors long winded vijeos without any swearing. Glad I remembered you made a video on these!
Your videos helped me fix my ingersol-rand impact now its helping me understand pto’s that i work with daily better. You got one for everything dont ya
The ISO code on the pump body is stamped "P " for pump or "M" for motor , Motors also usually have a case drain port.it would appear someone has swapped the rotation group to change direction. You have a pump in this clip as indicated by the seals on the thrust plates ,a motor is bidirectional and the thrust seals seals are figure 8 shaped .
Great video, your ability to explain relatively complex workings is second to none. I was going to ask your option on a brand of tool the other day and bam there it was, what do you think about porter cable?
Glad you mentioned cavitation. Put your hand underwater and move it from one side to the other really fast. A vacuum pocket will form behind the hand that you can easily see. There's no air in there, but it is a cavity. I have also seen the inlets being pressurized to reduce cavitation. The highest I saw was 100-PSI, and that was on a 3000-PSI system. Great vidya, my friend...
I never really thought about the details of a gear pump and falsely assumed that the oil goes through the middle part, but had been wondering how it would do that as the cavity is pretty small there. Doh. That the oil goes _around_ the outer diameter makes much more sense. #TIL. Your vijeos are a source of interesting information. Skookum as frick. Thanks!
never thought about it until seconds before he was explaining it, but I too assumed the flow would go through the middle. which makes absolutely no sense in retrospect
I always imagined the closing in teeth would pressurise the oil (although the oil doesn't change in volume very much at all unlike with compressed air) with some leakage but yes going around the outside makes more sense.
Great video! Could you possibly do a video of the internal workings of a hydraulic pump/motor and how it transitions between the two functions? Thanks!
The cut out pieces on the gear side of the bearing holder only allow oil to escape back out into the side of the pump that it came from. Because the groves don't break into where the bearings are. The groves on top do look like they allow the high pressure oil into the bearings. I think this makes sense because if the oil was flowing in and out of the bearings it would not be at as high a pressure. Also I love your channel, and I wish I had lecturers like you at uni.
As someone who lives in a former colonial outpost, the easiest way to tell imperial fasteners in my garage is by the rounded heads from using metric tools on them...
Another well tested method. Eyeball the fastener, and select the tool you are absolutely certain will fit it.. if you selected metric.. it will be imperial... and if you selected imperial it will be metric. Uncanny.. works every time for me.
After hearing you talking about pressure and flow, I wish you would do a few videos just on the basics. Kinda like what you would see in those old education film from like the 40's. Because without a doubt you're knowledgeable enough to get the info right, and I feel you would easily be able to put it all in layman terms.
Put my 48 Ford 8N into a tree stump, cracking my loader pump case earlier this year. Had to self learn everything you just showed. This filled in some lingering gaps of knowledge from that day.
I keep waiting for the day when I'm going to need something I learned here at work. I work in the wireless internet industry, so there's not many hydraulic pumps and such, but some day!
Very interesting. From the automotive mechanic side is always throught it squeezed through the middle. This makes more sense now that i see you explain it.
Thanks man. Very in-fkn-formative. I had to replace the oil pump in my car about 20 years ago and for whatever reason I thought about gear pumps and watched your vid. Great job, good info.. Thanks again.
thank you so much for your help, u taught me so much I needed to know if a pump could run either way all I have to do is flip the gears wow thanks again
I am a mechanic for a company which specializes in truck mounted material handling loaders (primarily logs) ran completely by a gear pump mounted to an eaton pto on the underside of the truck transmission and driven by the input shaft of the transmission, typically when we see symptoms of a tired pump we only replace pumps, not disassemble and repair. This vidjayo defintely helped me understand a little more of the witchcraft that goes on inside these pumps
I was always under the impression that hydraulic motors had the same size ports on either side, so that the motor would spin the same speeds in either direction. Then hydraulic pumps normally had the larger size for suction and the smaller size for pressure, depending on the application.
oh and the bearing cut out bits are also to ensure there is flow of new oil past the bearings to keep them cool and lubricated. I dunno if you can get your hands on a variable displacement piston pump, but them things are pretty cool as far as pumps go. we use them in our manlifts for the drive circuit.
Moe7404. i worked industrial hydraulics for 20 years. now retired. that demo was the best that subject could EVER be done. the part about pump or motor is a point that even a lot of people that work on them dont even understand
I to work in the hydraulics industry and it does catch a lot of people out. What he stripped down was actually a pump tho because of the 2 different sized ports and the kidney plate seal only sealing off the high pressure side. Some pumps like commercial brand actually run a full seal around the shaft like a motor has but the ports are the give away.
Ist a one directon motor wich needs the sealing only on the higpressure side an a lekage flow from the bearings spots to the Tank side The actuator is labeld as a Motor also Greetings from germany
Excellent, I have been trying to figure out why my pump wont build pressure and heats up quickly, after reversing the rotation I didn't get the excess fluid diverter in the correct orientation, works great now, thanks!!!!
Thanks for the explanation. I've mistakenly thought that the pump moved oiled through the mesh of the gears. The first thing I thought when you opened it was how does the oil move through such a close mesh. Now it makes perfect sense that it doesn't and in retrospect it was a little stupid to think that it did...
Dear AvE, your videos have kept me interested in engineering and thus lead me to my degree. You are just the best. Thanks for putting all the work you do into these videos, man!
Good work m8. Gratz on your degree =D
Cheers to that. Very cool you found that inspiration
Same story with me but ima machinist 🙃
I absolutely love these kind of videos. Nothing beats the hands on explaining. Please keep these up!
Impeccable explanation! And I love how you stress the flow/pressure distinction.
Hahaha, I laughed way too hard at the click of the tourque wrench. I'm guessing you tourqued it to FT (fucking tight)
Jeff from elderly iron has the same torque wrenches...
me too lol
It took some learning growing up to stop at that click before the fastener said "Ting", and my knuckles chimed in.
FFT. That's Full Fucking Tight, for you. Any tighter and you get stripping.
GOOD-'EN-TIGHT. Yah .
I've never even considered engineering until i came across your channel a couple years ago. Glad you can share joy of machining with us common folk.
Your hydraulic videos is how I discovered you, your infrared heat gun trick is worth its weight in gold. Keep up the great info.
This video given me the exact knowledge that I need to know now a days for my project. Lot of thanks for uploading such a brilliant effort.
11/16 wrench on a metric bolt. Never change AvE...
ha..it is a crapsman wrench tho
Just 0.46mm too large, doesn´t matter that much on 12.9 bolts, they´re hard stuff.
If the Crapsman dies on it, who cares?
Wasn't a wrench it's a torque device....lol
I use 3/4 for 19mm and 5/8 for 16 all the time, call me a rebel.
it's 11/16 of the proper torque
Love these vids. I'm not a mechanical engineer or anything (just a web app developer), but I love watching technical stuff and learning. I work on my track car, so I guess this sorta falls in line with it.

+AvE I like this new frequency of video releases. Keep it up!

You're a knowledgeable man! And i'm glad to learn something new from you every video!
Hydaraulik relef valve
Relef valve experience
I was so pumped for this video
Got a university report on gear pumps and was getting bored of my tutors long winded vijeos without any swearing. Glad I remembered you made a video on these!
I learned more in 10 minutes regarding the workings of a hydraulic pump/motor than I ever did watching UA-cam videos.
I was looking for a repair video on hydraulic pumps and you came up! VERY COOL! I love your videos! Thanks!
Thanks for another great video ave.
It is really fascinating to see the inside of the gear pump!! Thanks for the video
That was incredibly informative. I love your videos.
That was awesome! Actually great info and fun while we are at it! Love it!
Just picked up a little scrap honor pump from work that I'm gonna disassemble and attempt to fix. Your videos definitely helped get me interested!
Aliminyum ana gövdede çizik varsa o pompa ölüdür , bogaz keçesi yada gözlüklerde, keçelerde problem varsa belki kurtarırsın pompanı .
Very Good man! I’ve learned a lot in so little time! Thank you.

You have a great deal of knowledge telling the difference between the two. You should have a UA-cam channel.
@@dukeman7595 I run a hydraulic repair business.
Great video, your ability to explain relatively complex workings is second to none. I was going to ask your option on a brand of tool the other day and bam there it was, what do you think about porter cable?
I can’t believe that it’s almost six years since I first watched this video. It’s still great to watch now. Thanks.
Another great video Ave! Learned a lot, thanks!
I just had to rebuild one of these on my PTO for my wrecker, and damn. This knowledge is great.

I made the same assumption

I love you man. I never seen such an explanation like this for gear pumps. neither in books.

Great vid, would love to see more. ie spool valves, proportional control etc etc

Another well tested method. Eyeball the fastener, and select the tool you are absolutely certain will fit it.. if you selected metric.. it will be imperial... and if you selected imperial it will be metric. Uncanny.. works every time for me.
If it's an American car either might fit, if it's a Japanese car metric tools will fit but you hands won't!
Hey... let's all switch to metric! And let's put the steering wheel on the left side as well, while we're at it!
This is awesome , im taking a hydraulic design course right now so this is at a perfect time!
This was actually Quite informational! well done +AvE
Thanks for the video and for the clear and detailed explanation!
I always wondered about the IN's and OUT's of a Hydo pump.... and now I even know the in-between's.
Had to re build a couple of those last winter, i had absolutely no idea how they worked but somehow the re builds went good

Om Gosh Ave...
You have a video for everything.
What is it that you do for a living?
You're a genius.
Great video, and great style. 10/10!
Thanks for making it humorous too.
Damn man, that was an amazing explaining
just stumbled upon this channel, 2nd video in. I knew right away this guy is smart and funny. Keep up the good work!
Great, always learning something with your vids.
I love how you go into detail on how to verify that it's a metric bolt and then you wail on it with an 11/16 wrench. You can't script gold like that.
Celeb reply here!! Sorry it took me 4 years to notice...
Put my 48 Ford 8N into a tree stump, cracking my loader pump case earlier this year. Had to self learn everything you just showed. This filled in some lingering gaps of knowledge from that day.
thanks for helping my hangover with your soothing video
Very loud and clear, thanks for sharing this information
I keep waiting for the day when I'm going to need something I learned here at work. I work in the wireless internet industry, so there's not many hydraulic pumps and such, but some day!
Think you should find some vajayos that’s apply to your needs friend
Very cool and interesting video! Thanks for being informative.
Very education and accurate. This helped me to understand the K46AC transmission. Thanks
Best explanation ever. Thank you.
Hey man, I hope you see this. I just wanted to say I love your videos.
Very fun and educational. Some of the best entertainment on youtube.
Chooch.
I appreciate your clear explanation and good reasoning.you are professional. Thankyou for sharing without holding any secrets.
Very clear good views,explanation,and comprehensive language;as much as vocabulary,u can tell the speaker knows what’s an hydraulic component
Awesome job! Very informative! Thank you
Sir, you have a way of breaking down high end knowledge to my level. Also, I can't stop saying chooch or skookum. Thanks!
Very interesting. From the automotive mechanic side is always throught it squeezed through the middle. This makes more sense now that i see you explain it.

I've been taking things apart since I was 5, and I gotta say I love your channel, even if you are Canadiene. Keep it up
I love this channel...always make great videos!
You are off your rocker.....I love it and the smoo is seeping in....thanks for the enlightenment.
Nice video. You should do an anatomy of other pumps as well.
I also got this pump and i made it into a powerful pressure washer. Thank you so much
This was quite informative. Thanks!
+AvE Awesome ViJao Dude & Very Cool Motor. I certainly learnt a lot from this video. Keep up the great work. Nick.
It's a lawnmower supercharger.
Does that mean it force-feeds grass into the blade?
Like how I put USB cords into the plugs.

know what?youre my favorite youtuber from now on..more power to your channel.
One of the best I have seen. Thanks the cloud of hydraulics is lifted.
Very great video! And much appreciations!
Learned a lot on this one. Thanks
Very interesting. Keep on keeping on.

well thanks again Hoser, beauty lesson. very entertaining way of educating.
you should do one on a piston pump works, and explain how the charge pressure is created and control (Parker valve). awesome video
Thanks AvE!
Great video as usual! Check out melt pumps for plastics, same thing only a lot bigger and much hotter.
Love you vids man..! Keep up the good work
Very informative.....I think I learned something.
You explain things brilliantly. Any chance you could you could get to England by tomorrow and teach my auxiliary course?😩
Haha "click". Totally torqued to spec like a boss.

Greetings from germany
Moe Shouse I have an old backhoe and not really any power or force when I’m using the backhoe part. Would it be a bad pump?
Thanks for telling information about gear pump
Such a good video, so much simple and good information I immediately paused and took notes in my notepad app.😎👍💯
i feel ave knows me, i do roll my own smokes and can kickstart a harley
but are you female?
was that aimed at the od female in the crowd then? didn't notice that xD
Quit smoking, roll a joint and switch to enduro (dual sport).
I like how simple and straightforward it is
Fascinating stuff! Did you have any plans to use this motor in anything, or did you just did it up for edumacation / demonstration?
Excellent, I have been trying to figure out why my pump wont build pressure and heats up quickly, after reversing the rotation I didn't get the excess fluid diverter in the correct orientation, works great now, thanks!!!!
On the rooftops of many buildings there are HVAC refrigerant compressors that are screw type gear compressors.
Pretty awesome machines.
thank you very good explanation with clear voice.

So hydraulics are the big boy version of wimpy pneumatics? :-)
