G'day! Can you please explain how the v- selector and pedals (for steering) work on the Cat 953/963. I can't figure out how the lever controls (left driver controls) the swashplate (left and right pumps)and the pedals at the same time.

Great video. Helped me with understanding the internal passages. Thank you

Damn I missed this one!

Hi sir, I am from India just learning from your videos, Please continue

Brilliant video 👏🏽

Hello sir, I am from India, pls make a video on excavator system with animation

awesome videos

Sorry sir , do u have data of dimention of piston brake of swing motor CAT 200 E ? If you have would you share with me , n before thanks a lot

Already an old video but couldn't be explained better , thanks a lot

You do such a great job of explaining how these components operate.

thats how you know its working

Please explain difference between DR controller and DFR1 controller , basic difference is DFR1 control both pressure and flow . If we use closed loop DCV then how both type of controller will make any difference? What benifit we have to choosing DFR1 over DR? As both has almost same internal circuits.

very nicely explained

So is it safe to say that Load Checks could not possibly be a factor for Tilt Cylinder Drift when the spool in the HOLD position as the Bridge ports for the load checks are blocked by lands on the spools. (assuming intact iron no cracks in valve body). Also, you went over port relief valves and some newer machines have Pilot Operated Directional Control Valve/ BICS Lock Valves on the lift and tilt circuits with a built in relief to Drain. I've removed mine and checked the orings and back up seals to find they are in tact, but im starting to suspect failure inside the valve itself. They are quite expensive and to just throw the part at my machine is not ideal. Is it possible to Bench test the functionality of these types of valves?

Incredible video! Any possibility you could show/describe how to install the detent balls and spring for the lift spool?

This video is really awesome. How to make schematic animation and what program is used?

thank u very much, it helped a lot to understand the system before check the machine schematics

Excellent video!

Tank you very much ❤❤❤

Excellent videos! I have a 763 that is having an odd problem and nobody including bobcat can figure it out. They finally told me i need a whole new control valve assembly for 4k but none are available. Looking for a used one. With the machine running, if i lift the arms up and leave them for a minute, when i go to lower them, its hard to push the pedal and you hear it loading up like hydraulic pressure is building. Once it overcomes the arms drop roughly. This is exacerbated when there is a load on the arms. I have to lift the load up a few inches and then quickly start lowering it. I have to do that a few times to get the load down slowly. If its just a bucket of dirt i can push the pedal hard and overcome whatever hydraulic pressure Is building and it operates somewhat normally. Maybe this issue will interest you, I would really like to figure out whats causing it even if i find a replacement control valve.

What am I missing?

I would like to know more about this particular pump bcoz I can assemble it but don't how it works and it's always passing the test results please pin me

amazingly detailed thanks for your effort.

Great explanation ☺️

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

great thanks very comprehensive explanation

Great explanation!

Teşekkür 🇹🇷

Thank you so much. Good explanation.🇹🇷

Excellent explanation.

I just picked up a 480C and waiting for the books to get to me. I need to know how to properly check the hydraulic fluid on the machine. Previous owner said, WHILE RUNNING, IN 4TH GEAR. And nothing more. I read somewhere it has to be in transport position. Nothing totally clear proper check. Could you help? According to the serial, it's a 1979 Case 480C Thanks

How to isolate the pump from a disasembled hydraulic system when working on the engine. I've got an old backhoe someone took apart.

awesome .

I think your videos are excellent. Really appreciate your content! Please Keep up the good work 👍 🏴󠁧󠁢󠁳󠁣󠁴󠁿

I LOVE YOUR VIDEOS ...THANK'S FOR SHARE YOUR EXPERTIES ......

thank you I had disassemble my but didn't pay close attention same pump thanks trying to change the rotation of the pump

We thank you for your excellent content. Would you please make a video about the hydraulic circuit in the Caterpillar 349 excavator, please?❤❤❤❤❤

How can i get this char

Great visual presentation 👌 are you on Linkedin?

Wow am the first one to comment

Can you do a video on how a breaker work on a hydraulic system. We have some machines that have 2 different setups for running a breaker vs using a thumb.

Can u explain more to us the cut in and cut out on the brake schematic

Can u explain all these things on the brake schematic

Hi I was missing a movie like this. Great job, perfectly explained. I just hope my English allowed me to understand everything well 😅. Regards.

👍

This has answered so many questions I had on how these work with excellent visuals. Thank you!

Your videos are the best, do you know of any online courses available in Canada that a Red Seal mechanic could take to help fill in any gaps in knowledge when it comes to hydraulic systems used on equipment? I'm a perfect case study of the Dunning Kruger effect where when I was an apprentice I thought I knew it all but now 15 years later the more I learn the more I realize how little I know. Keep up the good work.

I'm not sure why I keep saying 10 connections, when there's clearly only 8. oops.
