Hydraulic System Inspection & Troubleshooting Session 1 

I am suppose to start a job and they ask me how much I know about hydraulics. You sir are a life saver! I am still learning at 63

Good job. Well done.For you young people out there with an interest, please pay attention to your mathematics lessons. Also don't forget your basic physics. Not only Pascal's law is involved in hydraulics, but Newton's 3 laws of motion also. To become a successful person in life, you must know your basics. Keep studying.

Adam and Paul: Thank you so much for taking the time to do this series. This is what RU-vid is all about! Also Adam, my sincere sympathy for your recent issues with theft. I've gone through it myself and I totally understand the feeling of violation. I hope you recover, and remember that there are far more good souls out there than bad ones. Keep up the absolutely excellent work!

Where is part 2?

HI Adam, I have worked with hydraulics for many years. This was a very good presentation and explanation of basic hydraulic components. I can tell your friend, Paul, has taught many classes on this. Great Job! Thanks for sharing with us. No matter what you know, you can always learn more! Take Care, Reid

Adam, I am liking the Hydraulics training,, watched the first one last night. Thanks for putting the series together,, Harvey

Very nice presentation, enjoyed and learning/understanding of hydraulics is very helpful...

Thanks Adam, for letting Paul give this great presentation, for all of us to share in. Great job guys,

When the video started I thought " SHIT.... ADAM'S BUILT A TIME MACHINE"....................

This guy needs hydraulics to get him out of bed in the morning

What a wonderful surprise to see this video this morning. Thanks to both of you.

Hi Adam, That tutorial is AWSOME.....! THANKS A LOT....! This is great an unexpected surprise, this is going to help me with something that I'm much less familiar with. Just a question are you and your friend going to open up pumps and componants to show the internal aspects in functioning or defective units and so on.....? So many questions but I'm kind of exited. Cheers, Pierre

Adam- Awesome series. I understand electrical circuits, and mechanical linkages, but hydraulics are new to me, and I'm looking forward to finally 'getting it'.

Very nice idea for a video series. Thanks

Great video Adam!! Your man Paul is quite a natural teacher; very nice manner of presentation. We had a fluid power seminar at a local industrial supplier (Eastern Bearings) and his presentation style was similar; very mellow and enjoyable. Keep 'em coming!! Thanks, Sean.

Good refresher :) There are lots of hydraulic designs, so don't be surprised when you pull the reservoir cap on a CAT excavator and find that it is under pressure to aid in hydraulic flow, or when you check the pressure of a pump that is designed to regulate the pressure based upon flow demands vs dead head pump pressure.

Excellent presentation guys. I enjoyed watching. ;-)

Great video Adam, a few years ago I used to work for a hydraulics company but didn't get much into this side of things - very informative - thanks to you and your buddy. Mark from the UK.

Form a physics standpoint air is a fluid, so please reword that to "You cannot compress a liquid". Pneumatic systems are also a form of hydraulics, and far spookier than hydraulic oil, to play with, when used at high pressures. A good friend of mine moved away in the wee hours after a compressor in his shop went up through his roof and came back down through a neighbor's roof.

Very nice video, Thank you Adam and Paul for doing these video's. I remember learning some stuff a long time ago, excellent refresher. Matt C

Great start Very well explained I remember a teacher explaining flow and pressure Urinating is a good example open good flow Slight "squeeze" more pressure less flow

Great stuff guys, I operated hydraulic cranes and heavy equipment for a good part of my life. Hydraulics makes my life go around !

Really hoping for the next videos, This is a very educational series and I hope you get time to put up more of these since this is the only series I've found that explains the hydraulic system and the troubleshooting methods in an understandable manner! Also on that note it would be great if you went over the use of restrictors in a system (to slow down the movement of lift arms on the way down?) Thanks, Love the channel Jamie

Adam and Phil....EXCELLENT series. I've never understood hydraulics, and this series is very informative. Thanks for all the effort it takes to put it together.

Hi Adam, since u had Paul on hand r u gonna fix you newest toy that I believe had some problems that Paul could fix

Adam and Paul, I can't remember the last time I attended any classes! Thank you for the refresher! If memory serves me correctly, I think it was in 76, when I was introduced to hydraulics. Thanks for putting this together guy's! Looking forward to the following series. Razor!

Thanks, Abom79 for this video and series. I never understood hydraulics and always wanted to learn-looks like these videos are exactly what I need. Nicely edited and commented too!

Hey Adam and Paul, very interesting session and great idea. I really like the subject. Thanks for pushing your channel in new paths.

Adam, really excellent job. The instruction and your video production value is excellent. While speaking to production value, your opening screen combined with your new logo is extremely well done. With how interesting the content is and how professionally it is carried off with many of you "youtubers", I see no reason to watch TV any more.

Great video on Hydraulic systems The display setup is Awesome

nice to have a guest speaker to introduce us to hydraulics. Can't wait to the next what is next. I found this to be very interesting. Keep up the good work.

Adam & Paul nice job, looking forward to the next parts. Maybe share some of your charts via google drive or dropbox?

Guys that was excellent. I knew almost nothing about hydraulics and now is my opportunity to learn. A question about the horse power required. I assume your are talking about the motor required to run the pump? And the size pump would depend on the gallons per minute/hour needed to accomplish the work? Thanks again for this video. If you don't have time to answer the question, don't worry about it. I know you both are busy. Rick

When I was a child learning about electricity the fluid analogy helped. Current = Flow / Voltage = Pressure. Sure, It doesn't apply to many situations (Transformers) but it was a useful analogy. Really understanding Paul's basic concepts can lend to your ability to troubleshoot many different exotic technologies. Thanks for the physics lesson Paul, Glad you showed the thermal image as a tool to visualizing the loss of energy, whether caused by a restriction or even a sharp change in direction.

Great tutorial. Paul does a great job of emphasizing the "take away" from the lesson. Thanks Adam for sponsoring this!

Hey Adam, 20000+ subscribers. Congratulations. Mehmet

Adam, What a great video! This is right up my alley -- I love learning new and exciting stuff like this! A super great presentation! Thanks a bunch! Have a good one! Dave

Cool stuff. Hey Adam, I repaired a hydraulic system one time. The actuator/ram would not extend with full force. There wasn't any obvious problem. The pump was inside of the reservoir. There was a short hose inside of the reservoir leading from the pressure side to the hyd. system. The hose had a leak! I replaced the hose and voila, full pressure... fixed!

Thanks Adam and Paul, looking forward to next instalment, material was at my level and presented well. Roll on to the K&T repair !

Awesome video, you guys are great. I am refreshing myself before I take a NOCTI test for a Mechatronics job and this is spot on with what I remember learning in trade school.

Great video Adam , I work on my own hydraulic's on my farm equipment , these video's are perfect and will help me understand the systems and be better able to diagnosis and repair those systems . Plus , without causing further damage to the equipment or ME !!! LOL thank you , Bob k

Another 2 cents worth. Gasses and liquids are both fluids. Gasses compress and liquids do not compress. Both are fluids so be careful of terminology. Okay?

GREAT STUFF Adam. Better than I was shown in 101 collage hyd. 30 years ago lol. The rotary is a great use for tapping heads on GUNDRILL machines for water lines ect. As it is a positive drive and instant STOP/ Reverse .for driving GOOD size taps ie 1 inch NPT.

When are you gonna have Paul help you diagnose the K&T Horizontal mill? I'm looking forward to trouble shooting it.

Adam, very, very cool...! I have several hydraulic systems, but have no real basics on how they work (self-taught in pretty-much everything). This is really useful information.... Thanks to you and Paul for this...... Looking forward to the other sessions.... Cheers, Daniel.

Does this mean the K&T will be running soon? Interested to see what that thing can do.

That was awesome Adam I have always been curious about hydraulic systems. Also a big thanks to your buddy Paul. Can't wait for the next session.

Great video, thanks. I am looking forward to the rest. I've wanted to learn more about hydraulics but never found the time, this series should be exactly what I am looking for. Thanks Adam and Paul.

Not much to hydraulics, Adam. Your truck/car has a few hydraulic pumps in them: the oil pump, automatic transmission fluid pump, and power steering pump. The 1987 Buick Grand National had a "HydroBoost" braking system. It used the hydraulic pressure/flow off of the power steering pump to assist braking. Since the engine was turbo charged (pressurized), there would be no vacuum to actuate the Vacuum Assist brake system. there are other different types of hydraulic pumps, but they all do the same thing: pump fluid. Forklifts, BobCats, tractors, backhoes... all have hydraulic systems.

Very nice training video. Quite helpful, thanks!

Definitely informative. When I was in community college, I used a trainer much like this one in my Fluid Power course.

adam i liked the video.

Hey guys! English is not my first language so it would take some time to google research and translate the right word to describe this video... AWESOME? Yup, that kinda does the job:) hydraulic system buliding is an industry that has a whole bunch of poeple working in it that have no idea what theyre doing. So its difficult to get knowledge from that people. I have never seen someone describe this stuff so down to earth so that even a business person like with no technical background can understand. Guys I dont know if youre religious or not but putting this demonstration and course for free to the public in my eyes should be written down as one of your good deeds :) :) cant wait for the next part!

Hats off to Paul and you too Adam, for a very easy to understand explanation on Hydraulics.......well worth the time to watch.....PB

Excellent idea Adam! These kind of videos are the ones that makes RU-vid to have any real purpose beside all the junk that you can see most of the time. Thank you and Paul for taking the time to share your knowledge!

Hello Adam & Paul. I enjoyed this video and the other one about essential components in a hydraulic system very much. They are very instructive and clearly illustrated and explained. I do have a question for Paul though: If the motor (and the pump it drives) is slowed down (say through a Thyristor electric power regulator or a variable powersupply) does that reduce pressure or flow? in other words, do you reduce the amount of horsepower transferred to the pump or do you reduce the speed of flow of oil? I would tend to say it reduces flow, but I could be wrong, that's why I ask the question :) Thanks for considering my question Wonderful series, wish there were more of these available on youtube

Excellent video and topic. Goes along with the repairs you do on hydraulic cylinders and maybe see why the failures occur and keeps you busy. LOL

Great video for the series. It might should be pointed out this is an Open center hydraulic system. There are also closed center systems in which the system is constant pressue and the pump flow varies to maintain it vs constant flow and variable pressure in this system.

Wow! What a great class. Thank you so much! Eric

Great videos! I can’t find part 3&4

Very usefull, part 2 was nice for a electronic guy. :-), looking forward to see 3 & 4 when they come.

very hard to follow an extension pointer when it keeps disappearing? poor filming

Thank you so much. I am working on an old backhoe and cant wait to session 3. If you pm me your address I'd like to donate to your cause

Cool video. Looking forward to the second edition. Paul and Adam, thanks for doing this for us.

Many thanks to Paul and you Adam for this training. Very useful knowledge.

It's very nice and informative presentation. However, I can't find the session 3 & 4............need help!

like this

Moss! mas onde andam os restantes vídeos? (This is Portuguese from Algarve :-) ) Thanks Adam, Very good tutorial! I could not find the following videos, do you mind to put some links for them?

Would Paul come onsite to our business and do some classes?? We are dealing with various sizes of hydraulic press equipment steel stamping etc.

Mr adam. I am hendrik from indonesia.sorry if i anderstand english only a little.can you help me. Iwantto aasemble a mini exavator. I have 10 Hp machine.i want too as you. what type of. hydralic pumpi used.hand valve used. Orbital pump used.diameter of hydraulic cylinder and engine and pump connection use belt or chain. Thanks

Awesome video!! Any idea when the next part of the series will be out? Cheers

Hi Adam those videos are awesome especially hydraulics i like them

Good idea on creating the series. A good review for us guys that haven't worked on it for awhile, and a great tutorial for newcomers!

very nice equipment and very educational thanks for the series.

Great video, I have been a diesel mechanic for 3 years and have always wanted to learn more about the hydraulic systems used. Very informational, thank you!

very informative,looking forward to next series.Thanks Adam

I have a problem with hydraulic overheating with my excavator (bobcat) 435 also the aux have lot of presure on it. Any suggestion from anyone can get me a hand on this?

I didnt sit through the whole thing but the biggest thing for me on hydrailuc systems are fluid leaks through the fittings. if you upgrade your system to quick connects and leave the system articulated and come back later, just how much pressure is going through those lines is apparent by the fluid working its way out through the loose nuts on the lines. those fittings have to be very very tight to contain the fluid. and the fluid can never be dirty or contaminated. pressure relief valve explaination was a good part of the video I hadnt seen yet

HI adam I was wondering if your going to post the rest of the series as I just started doing Hydraulics at tech

Great vid there Adam and Paul Better get Paul on the K&T I always think things out in my core skill electrical for me pressure is volts and amps flow, you need volts to get the amps flowing , well it works for me as it dose for pneumatics and fluidics Looking forward to the rest of the series Stuart

I had to return to this video and use the share feature. Someone who should know better is adamant and loud and he is wrong, again. I have never missed any of your videos. It is February 04, 2018 today. Your videos only get better and more professional with time.

To me, as an electrical engineer, this can be translated into Ohm's law. Resistance is the same in a hydraulic system as in an electrical system (It is limiting current/speed and accounts for amount of voltage/pressure). Speed in a hydraulic system would translate to Current in an electrical system, pressure would translate into Voltage in an electrical system.

You got the hydraulics guy there, now get that K&T sorted Adam We need to see chips coming off it. :-))

Thanx Adam and Paul very interesting video. Can you tell me what type of pump that unit operates ? Gear, swash plate .... ?

In one of your video's you said about people following you on Facebook? There is no follow button or friend request button when I looked? Sent message but it says it was going into your "other" folder or I had to pay $1 to send to your inbox?

Hi, I'm a technical institute student at Hydraulic systems technology , how can I figure out the latest things in my field,

My pump is rated at 1500 psi 60gpm, I need more pressure. If pumps dont pump pressure, why will my pump not reach 3000 psi?

this is awesome. I'm just about to convert a gas powered lawn sweeper to hydraulic power and add a hydraulic lift cylinder for the dump door.

Thank you so much for part 1& 2 but i can't find part 3&4,how can i get those remaining session please

I have a problem of a circuit breaker on hydraulic systems keeps tripping the breaker ....any one can give some information

Lots of great information. I've always wondered why the hydraulic filter is on the return side of the circuit instead of on the input to the pump. The way it appears to me is that the low pressure side comes right out of the resivor tank, unfiltered, into the pump, then goes through all the devices including the filter and back into the tank. Hope you get a chance to see this quetion and help me understand why that is.

i realize this is an old video but I have a question... can I plumb a hydraulic motor to another hydraulic motor, spin one by a hand crank and get the other to spin? i'd like to use 2 motors in a steering system. one motor will have a wheel attached to rotate by hand and the other motor will be attached to a steering shaft. will this work?

A great video, why did so many people knock it ?

Thanks for your helpful tutorial.please talk more about troubleshooting tips

One question...how would someone go about filling up and bleeding a system like that training unit where there are seemingly a lot of places an air bubble could get trapped?

thank u allot for this job but i need pdf or video about how to inspect hydraulic system and it's component and thank you

The stopwatch times are good examples of a lapel microphone time.

Much appreciated and interesting video! Well done instruction, clearly put. I am off to my tractor and cherry picker to see how the two hydraulic systems I own work. This is a super useful service you are giving us, Adam. Give Paul a pat on the back and tell him his lessons have influence well over the borders of the good ole USofA!

Would like to share inhelicoptersafety fb group¡¡

Great stuff Adam. Nice refresher as well as actually learning a few extras too. Thanks.
