Hooking and unhooking hydraulic hoses under pressure for Ku

- This is a video hopefully to show how to easily hook & unhook hydraulic aux lines for attachments, like shredders and grapplers etc...
Thank you for the tutorial. This isn't our tractor and we spent way to long trying to hook the hydraulics before I found this. Thanks again
Great tutorial! I'll need to add this to the "watch list" the equipment rentals in Dickson, TN. Mini-excavators and the mini-skidsteer renters will really benefit from this simple tip!
Extremely informative and useful video. Thank you for sharing your knowledge and experience with the rest of the world. Much appreciated.
Thanks, I've been struggling with mine every time I use an attachment, I am renting a tiller tomorrow, so I will use your technique.
Excellent idea
Mine don’t bleed off easily like yours. I even unscrewed the connector to allow fluid to bleed, still without success. I have a Kubota L6060 tractor with third function for grapple. I have wondered if this is primarily a problem with these flat connectors. I don’t have any problems with the other designs. These are almost impossible to connect about half the time.
Very nice!
Brilliant!
Helped me out
What is the Pressure Relief mechanism called please ???
Thanks, not sure that helps for 3rd function valve on my kubota tractor. It doesn't have that "twin" valve, rather two separate. Good simple video. Thanks again
What if the pressure is in the equipment your hiking up. Mine is the backhoe. Dang it's alit if pressure. I had to unscrew the hydraulic lines
how about for the couplers at the top
Well what does one do if it’s stuck on
how PN for coupler
I'm gonna start isolating the Aux lines before dissconecting
Guy we have the worse time pushing those things in.it takes all our strength.Its a Cat 907h2 front loader what can we do for easy hook in & off.
Sometimes Cat equipment have a button to release hydraulic hose pressure
WHEN ITS' UNDER PRESSURE, THOSE COUPLERS CAN'T BE BUDGED. I HAVE NEVER BEEN ABLE TO START THE COUPLER TO RELEASE PRESSURE LET ALONE PUSH THEM ON.
bear9923 you are right I have never been able to relieve the pressure on my root grapple bucket without cracking the lines all my other attachments don't have any issues
I used this method to make 2 kids
I’m calling bull shit! Flat connections I have are a pain in the ass!
Why would you connect them under pressure?
Because without that device you have no alternative other than to crack the lines off
@@jameslindley924 what device ? Why would you crack the lines if your trying to connect the lines. Don't you crack the lines only when your removing the hydraulic lines. A little confused..
@@jay8a901
The device/mechanism he demonstrates where you push the Male into the female which pushes the female coupler back to release the back pressure.
You sometimes have to crack the lines off to release Back Pressure ( if the above device is not fitted )- which i have not ever seen fitted to an Excavator but is fitted to Tractors regularly.
The system sometimes for some reason pressures the lines whilst uncoupled hence when trying to push the Male into the Female its nigh on impossible ( lol) so the only way to release the back pressure is to crack the line or QRC to bleed off a little Oil upon which the coupler clicks in no problem.
The Back pressure can be on the machine side or the Attachment side, :- Our Selector Grab if it hasnt been laid on flat ground or has been moved about- results in the rotation of the grab shells which rotates the Drive motor and pushes oil back down the hoses up to the Male QRC's which usually results in cracking the hoses ( on the Grab) to release the pressure to make the connection.
Hope you can follow that
@@jameslindley924 ohhh. Got it. Got it. Thank u very much, why did people dislike this video? Is it because it's dangerous to do this?
😂
That’s not how they work they always have pressure
BS
