Quick disconnects on BX2200 Loader

[dannydan3]

The main hydro hose to my loader keeps disconnecting itself after raising the bucket to it's upper limit. Anyone else had to reroute these lines to avoid this? This is the Kubota loader, not a 3rd party unit.
Also, when this happens the only way I can get the bucket down is to use the float position and then reconnect it, is this going to cause problems? Of course I want to get it fixed the right way, right away. There is a vertical bar in the loader housing that I guess is supposed to route the hoses correctly, but I have tried both sides of it to get the darned hose out of the way and either side is still a problem. Either the hose is in the "disconnect itself" position, or on the other side of the bar it causes the disconnect fitting to rub a bit on the extended cylinder, which I don't want either.
Anyone else experience this?

Is you loader the new model or the old model? Does the joystick come off with the loader or stay with the tractor when disconnected?

If this is just starting to happen you might have a weak female fitting.

The joystick comes off with the loader, and the female fitting is solid, it's a new one, but the old one did it too. (haven't needed to have the bucket all the way up all that much)

I replaced all of the fittings since I had to replace one (and didn't want to spend $45 for one from the dealer). Someone was kind enough here to point me to Surplus Center - Hydraulic Equipment Electric Motors where I found three sets for about $36.

A picture of the loader almost all the way up might really help hear. I am not sure why that hose would pull off. With the older style loaders in which the stick goes with the loader, the entire thing should be pre-plumbed from the factory. Unless they messed up during assembly (to short a hose?), I am stumped.

May have to get a longer hose made. You should be able to get that done at a local forklift repair place.

I had the same issue when I mounted my loader once and ran the lines over each other.
I used a hydraulic jack to take hold the bucket weight and take pressure from the hydraulic lines and lowered the loader arms that way.

Ultimately, both the affected male and female couplings had to be replaced.

You might opt for having some longer lines made locally and then installing new couplings on them.

The couplings on my BX2200 (year 2000 purchase) got to where they were leaking. The ball bearings in the bearing ring on the female had worn small grooves on the ridge of the male section. The combination of soft brass and the ergonomics of the way the pieces fit together caused enough wear that the two pieces no longer seated together tightly. My dealer svc. mgr. replaced all my couplings with aftermarket couplers that were larger than the originals (Kubota didn't make the originals either-they came from an outsourced supplier).

Look for little pocketed grooves on the ridge of the male section. They shouldn't be there and if you find them, the couplings no longer have the restriction needed between male and female to keep them coupled. When the hydro pressure gets to max., it is probably more than the coupling can withstand, and they blow apart.
