QD's on Kubota Loader

[art]

those are not quick disconnects!

 

[Spaceman]

It ends up just twisting the hose

They are definitely NOT QD's...They may have been at one time (previous owner?) but they are NOT NOW!
It looks like a ORB to NPT fitting screwed into the valve, then a female NPT to female JIC or NPT swivel adapter to the hose.

I totally agree they do not look like qd,s, but they look just like the diagram in the loader manual which calls them qd's. Also, they have the protective caps attached which look like they belong there.
I'd talk to the dealer, but they are an hour away. Plus, they're not very useful unless you're buying something. Believe me, the folks on TractorByNet are far more helpfull and knowledgable than those guys!
Guess I'll just find some small diameter couplings and replace the existing one. Thanks for all the help.

Now you guys may be right, and you might be wrong. Some QD have a thread on the coupler. Check out this.

Double Shut-Off Quick Couplings - SafeWay Hydraulics


Safeway S-51 series has a hex nut QD threaded coupling.

They just keep on changing this stuff.

I believe these can couple under pressure.

Thanks JJ. Those couplings probably wouldn't allow enough clearance for mate/demate unless I offset them. The Parker ones you mentioned a couple of posts back look good. Plus, there's a Parker rep who visits the company I work for quite regularly and they have a facility nearby.

For what it might be worth, the remote QDs on one of my tractors do NOT have collars. The way they function to disconnect them, is you push IN on the hose at the connector and then pull the hose connector OUT, quickly.

I cannot tell from the picture if what you have might be these type........ doesn't look like they are QDs at all................

Spaceman,

Would you put two wrenches on the center hex nuts and undo them. I am thinking that they are threaded on , and believe they are QD's and drip-less, but not like the standard pull the sleeve type. If they are QD's, they will have a poppet valve on both sides. Please take pictures when the QD's are separated, and show the inside of each.

In the center picture below, the center fitting looks like the one on the Kubota.

Didn't get a chance to play last night. Couple of other projects going on. Will try to get them apart tonight.
