thank you for making this video!

I yruly appreciate your video, a friend bought one and I wasn't sure how it worked. I'll say this, I don't like it. It seems like you have to be a bit violent on it to get it into lock position. You would think you could go past center and pop a lever into place, or it would do it automatically. However, it's far better than my JD 500C BHL because that model uses a trasport pin you physically insert. And if your hydraulics leak internally within the boom, or you forget the pin is in place, you snap the piece off the main cast trundle, or whatever it's called. And mines been welded 20X by the previous owner, so I don't even transport the thing. Thanks for the video.

Great explanation please need same video for cat excavator 330D

Hi bud I’m having problems with my 330bl display I live in Australia and I have been quoted by caterpillar 6k for a new display what are your thoughts on a Chinese replacement for 400$ do they need to be flashed by Cat?

Good to learn something from you

Thanks for making these videos

I feel this is poor system for steering, so little specific information that trouble shooting is impossible

It's always a joy to absorb the knowledge that others were put here to convey. Thanks for sharing your gift!

You have the best videos with a full explanation of hydraulic systems.

My straps broke and it is now half in the pool help

Thanks for taking the time to make this video!

What valve keeps the boom from moving side to side on an old backhoe?

You have a masterful way of explaining it to the average individual. Thanks for taking the time and effort! Some were put here to teach, and I believe you're definitely one of them.

Awesomely explained! Thanks for sharing!!!

If it’s won’t rotate one direction what does that mean ? Got a smaller bobcat that will only rotate one direction and can spin freely the opposite direction

How does it work with the electro-hydraulic valve where two solenoids are stacked on one spool?

Please explain hydrostatic system no reverse o forward drive

Good day

Great explaining.

Excelente explicación.

Great video! I imagine that the wear parts are the o-rings in it, and those wear plates? Are rebuild kits available for them? I guess those two roll pins on those two high pressure gears probably get destroyed occasionally and the gear(s) just spins freely on the shaft? Thanks for taking the time to educate us.

Excellent explanation sir

Love the videos, learning a bunch about hydraulics. Great explanations and love the flow of your videos.

Класс!

Where did you get digram?

This is very helpful . Would you please send me your email I want to know about something about CAT 305SR Swing Motor

Unemployment expected

Wht is the situation pressure composetor valve operate, there is a posibility for load sensing valve oparate firsly and destroke the swash plte spool. So how does pressure composetor is operated

Very well explained , you do a great job at that

I've watched 4 of your vids in this series (a total of about 50 minutes), and now I know more about hydraulic pilot controls and how they interact with the main loader control valve. I learned more tonight watching your series than the last two weeks of watching KZbin.....Thank you so much, I will apply what I learned to work on my skid loader. Subscribed!

I have problem with a backhoe attachment bobcat 8811 When I'm using it , it makes a hissing noise I think it comes out of the valve spool body and one of the lines starts getting hot and if I use it for more than 10 minutes ,the oil gets so hot that it " kooks" seals from quick coupler and leaks 0ut hot oil... if you can help will appreciate . Thank you

Is their a kit I can buy

What kind of amp are u using?

Can you tell me where to add hydraulic oil to a CAT iH 28 loader

You got tow karma one of them hydraulic playing and the other gutter knowledge which are both my dreams ❤ nice playing and singing wish you a good luck in your life

Thank you from Russia 👍

Absolutely outstanding video, this is exactly what I was looking for. Thank you for taking the time to clearly explain the entire process of the pump, it totally makes sense now

Thank you for taking the time to make this video. It helped me understand how this operates, this looks exactly like the one out of my 2001 753G. I'm still struggling on how to use the float feature but now understand how it works. I had to replace the spool valve gaskets and rings and now understand. thanks again. I got the BICS valve wire plug and the pressure relief wire plug backwards as they are identical in every way and I failed to label them. After 2 years of dinking around I finally figured it out.

This video is excellent. It increased my knowledge of hydraulic valve controls to allow me to diagnose and fix my controller. Thank you!

This is very helpful.

Precisando assistir um desses

good video but needs better audio

23:59 could you share from which source you have shown the inside view of valve : the one from paper

Thank you so much !!!

Thanks for the video, it helped me understand how these blocks work, I am student doing machine shop engineering and haven't found a video as helpful as this one❤❤Thank you

I need your help , i have a digger that it sounded like it was laboring when i moved the bucket with out load on it , so i thought about how to test what was happening and i took both hoses off the cylinder and i hooked together with a T and a pressure gauge and the pressure rises to over 2000Lb just moving oil in a loop , it’s a cluster of valves with 8 spools , do you think it’s leaking internally between spools or what do you think the problem is ? It’s feeding pressure to both hoses simultaneously

Great info! I am still stumped with my issue though. Machine is a 7753. At an idle the machine will randomly go under hydraulic load. Like oil was bypassing properly but then stops bypassing. While in this unintential hydraulic load status(can here it under load), the base end of the lift and tilt works, but the rod ends of the cylinders will not operate. I did replace the relief valve under the lift spool linkage connection. To me, it does not make sense that both the lift and tilt are both affected the same. Any thoughts on what to go after? Thank you!

Hello i'm working on a project to automate an 7.20m long Sawmill, and i have a gear pump of 5 GPM, but i don't now if i would be too much slow to move the system with a 371cm3/rpm hydraulic motor?

Thank you!

Sir I am from India, Your videos are good all the time but please make a video on excavator throttle motor
