This guy has the gift of teaching. Thank you!

This is seriously the easiest way to check cylinders! Amazing mate!

Thank You for such a well presented video. No fancy moves, just straightforward helpful stuff as always!

I’m sardinian, here in my country I’m not able to find this kind of video-tutorials in my language, people like you are very usefull also to teach more english to us “the foreigners” ;) bless you

Absolutely great video! You described the problem succinctly with detail and with a demonstration. Leaving little doubt in the observers' mind! Well Done!!

What a great teacher. He's able to show things in such and such a simple manner that it's easy to understand.

Very useful, thanks a lot for sharing, the presenter is an amazing man, god bless

Another great video with simple easy to understand demonstrations thank you

Amazing to see. Simple but not obvious !!! Thank you

Very good demonstration and clear simple test. Thanks hips!!!!

Well done presentation. Thank you for sharing your knowledge.

Brilliant. Man you are really blessed with knowledge and teaching skills.

Your clips are very easy to understand even for foreigners like me. Thank you so much.

Best training i have ever attended infact its difficult to demonstrate theory as well practical... which is very well explained and covered

Excellent video, worth its weight in gold.

Great and clear explanation. Thank you so much.

A very clear explanation, thank you :)

Great demonstration and very useful - Thank you for sharing.

Great videos! Thank you.

Brilliant. Waiting for coming Videos.... thanks a lot

Great,, Very informative and easy to understand. Thanks

Good Test - Thank you!

Excellent video. Thanks!!

I love your teaching my friend ❣️.... Lot of thanks 💕

thanks explained very well

Great job, thank you for sharing!

Very well explained, Thanks Mate

Fantastic video!

Wooow I'll do this on my next troubleshooting job.. Helpfull.... Thanks

This video is very helpful. Thanks for sharing:)

Absolute Genius! well done

What, why, and how... Excellent!!! Thank You!!!

Great teacher, thank you

Simply genius at work..

Thank you very much. Keep up create so easy to understand videos like this

Great video!

Excellent thank you cured a problem for me .

WOW! I LEARNED SOMETHING MORE TO DAY, THANK YOU!

what a neat trick thank you

That was great

great video

Well done thanks.

Thank you very much for the explanation

Great info thanks

thanks That was great!!!!!!!!!!!!!!!!!!!!!!!!!!

thank you for your training, plz advise us the leakage criteria as well

Brilliant

Great videos

Right on point, thanks.

Good job👍

Continue the good job

Just what this doctor ordered ,thank you

Makes sense thanks

Thank you

Fantastic

I was thinking how would you do the load dropping test on a loose ram on the bench. Bloody hell, my eyes were opened. You get 6 out of 4 points for that demo.

Thanks friend

Very good thank you

thanks sir

Please tell me how you constructed that test jig. All parts required to build it. Thanks. Great video. I have a Kubota BX24 where the FEL bucket will curl up but when you release the valve handle it quickly drops down.

Thanks 🙏

Thank for that sharing sir.

Exelent!

Lot of love

Hi just came across your channel, I have a question I know probably won't be simple to answer but will see, I have a hitachi ex60-5, the pump is wining only when using the bucket ram, sometimes the when blading the bucket in the ground when you lift the boom up the bucket slaps open, due to this I got the ram resaled but it's still doing this, would it be a control valve?

Nice video. It's very helpful. A month ago, I experienced problem from two of our hydraulic cylinders wiper seal. The seal move out from its groove. Initially, I suspected there is a problem with the alignment or seal design. But later, after thinking and looking for possible cause, I found out maybe the problem is because the flow controller (miter out) at the rod side was throttled or restricted that caused over pressure that pushes the seal out. So, I adjusted the flow controller wider. As of now, I have not encountered the same problem but not 100% if my root cause analysis is correct. Please feel free to give your opinion.

Well, this may prove very useful in determining whether my telehandler boom leaking down is a cylinder or a valve to blame. I'm suspecting a valve because there are 4 cylinders to lift the boom, but it is possible that all 4 are leaking slightly I suppose!

Great way to test a double acting cylinder, is there a similar way to test a single acting cilinder?

Thanks for the video. i would like to know how would you test a cylinder to see if the barrel is faulty? if you have a video of that please share the link. Thanks

Useful

What happens if a cylinder wont move in either direction when working the valve?

yap pritty good how do I test prortional directional valve

Does all the quick connector's leaking valve can survive on working pressure?

This is a good example of what not to do. Never check a bypass test with the opposite side closed to air.

can you demo test a pto driven pump which has no leaks full oil but does not operate boom on backhoe ?

sir, this test applicable for more than one cylinder/piston more?

So if there is a cross port check valve included in the circuit before the cylinder, can the cylinder still retract under a weight?

I bought a valve the hose for the valve is 1/2 but that of the cylinder is small how do I determine the the hose for ut

Excellent video, very informative and educational. What's the name of that auto "leak free" fittings?

Good education

great ✔✔✔👍👍👍

If you block the piston end. What would the pressure read at the rod and piston. If the cylinder is OK

Is there a situation where this test would fail to diagnose bypass? What if there’s 2 opposing seals on the piston? Could that not create a situation where it would only bypass in one direction?

So a brand new cylinder will not move with this test? You are saying the cylinder you show should be rebuilt?

Nice 👍

Would this test work in reverse (capping the retraction port) to retract the piston? It seems unlikely considering your demonstration of surface area, but I’m curious. And would either of these tests work under a load? Please respond. Thanks!

Nice, So even if the control valve was leaking would this still conclude that the cylinder is leaking simply by taking off the back port and plugging things off ? Please confirm, thanks

Cheers

Very smarts 👍

I have a log splitter that works perfectly. I wanted to be able to remove the cylinder so that I could move the splitter down a couple flights of stairs. (Basically, I take the splitter apart so that I can manage its weight, all by myself, by taking it down the stairs in pieces.) My solution was to put quick connects onto the in and out ports of the cylinder. The problem I'm having is that the splitter won't work with the quick connects in the line. (Totally locked up... the ram doesn't even move slowly.) Could somebody please explain to me what could be going on here? I'd really like to get this sorted out, as I have to move the splitter semi-regularly. Thank you very much!

Disconnect both hoses and try to compress cylinder, how far will it move ? Try same test with piston seal removed, heck, remove piston all together.

looking to make a press for forging and pressing hot steel. air powered hydraulic bottle jack is too slow. I know by going with an electric motor and hydraulic pump like on a piece of equipment, like crane, backoh, ect... is the way to go. any thoughts on how to get 15 to 30 tons of pressure with the speed I see in your vidoes. am I on the right track with electric motor and a hydraulic pump system. does piston size matter on cylinder, and what about motor and pump size. forever grateful M. Weber

Bro Where are you from,,

I am actually hesiitant if you can use this technique for very large pistons. Can it be? Thanks!

when you removed extraction port , do you caped it as presented on blackboard

Is it possible for a double acting cylinder to leak during extend but not during retract? This procedure only test for leaks during retract. How can I test both directions?

thanks for the video ,would be possible to do a video on how to bleed the air of cylinder, (backhoe) for me

I have a log splitter that when I hooked it all up the motor starts fine when it's not hooked up to the pump but when I hook it up to the pump involves it down so much that it does not want to start what seems to be the problem here

what makes a cylinder act spongee
