BX loader valve quick connect

Does anyone else have trouble getting their quick connect valve to clamp down? Mine takes a little bit of wrestling to get the handle pushed all the way down. It usually takes two or three tries to get it to lock all the way down. I have a leak at the rear of the valve and I am wondering if I am not getting it fully seated somehow and that is why it is so stiff to get locked down.

Not sure if you are referring to the quick connect manifold on the newer models where all 4 quick disconnects are one unit, or the older models where each hose is attached independently.

In either case, before you disconnect the accessory (assume you are using the FEL?) make sure you sit it on the ground and wiggle the FEL control handle up and down and left and right. This equalizes all the internal pressures in the lines running to the FEL. If this is not done and you disconnect the hydraulics without equalizing the pressures, there can still be substantial pressure in one or more of the lines that can make it difficult to depress the plunger in the quick disconnect valve to get it to reconnect.

Good luck.

Post a picture or at least specify exactly which BX model you are asking about. There are differences between the various models over the years.

Re: BX loader valve quick connect

The OP has a new 1880, so hes talking about the unit with all 4 in one.

Personally, I like the 4 individual connectors. It gives you more flexibility if you have a problem. If your lift circuit goes bad you can switch your lines and use the curl lines to lift the loader and go home. One time i did have the problem of not releasing all the pressure in the bucket curl cylinder and could get the lines connected. Lift lines connected, lifted loader , took pressure off curl cylinder, connected right up. I was wondering if the new loader quick connect design was going to introduce problems, dont think extra complexity was worth the gain, the old loader on - off is really fast anyway, there has been enough reporting on this, jury is in on that. I feel same way about the drive over MMM, complexity with no gain on that either.

Re: BX loader valve quick connect

Orangetractor has it correct. I have an 1880 with the four in one valve. I love how quickly you can detach the new style loader, but the quick attach manifold needs some work. To get it to seat you can not have the loader all the way hooked up. So you have to pull up just enough so the hoses will reach then hook it up then pull forward to finish attaching the loader. Getting it clamped down takes a little wiggling and moving it around until it will let you start to move the handle. Then it's wiggle it some more, push down, wiggle it some more, and finally it will not go all the way down. I did some reading and supposedly Kubota has released a new one that works better but I only saw this mentioned once on a forum and can't find anything about it anywhere else. My salesman said he thought maybe the hydraulic coupler has worked loose, but I wiggled things around and couldn't see anything moving.

Re: BX loader valve quick connect

There is another thread here:

https://www.mytractorforum.com/326-k...fluid-fel.html

of someone else complaining of the same thing, and someone else replied that it is happening to them as well. They are waiting to see if Kubota is going to come out with a new design to replace some part involved. A workaround is apparently to bolt the two parts together to keep them from separating.

Re: BX loader valve quick connect

My tractor is at the dealer waiting for the part.

1. I did not lose a whole lot of fluid in loader operation as some others.
2. My leak occurred in the garage and dripped on the floor which was annoying.
3. Bolting the assembly together looks like you replace the two guide/retaining pins that secure the assy on the loader with bolts of similar lengths that clamp the assembly together.

Re: BX loader valve quick connect

Yesterday I finally got a chance to look things over. The leaks are coming from the under side of the loader manifold. When I looked under there it appears that there is a gap between the fitting on the metal lines and the bottom of the manifold. I can see at least a quarter inch of threads on the fitting. I assume that there should be no gap. My question is....how do I tighten them? I assume that they are similar to a brake line with some sort or double flare to keep the fitting on but still allowing the fitting to move up and down the line....is this correct? I am a little leery to start cranking down on a metal line blindly. I tried to find a good picture of the manifold but couldn't find one.

Re: BX loader valve quick connect

Ok, I found a decent picture. The red circle is where the leaks are coming from. The blue line is where the gaps are. All four line have gaps big enough that the round portion of the dust covers that go around the hard lines to keep them attached easily fit between the manifold and the hard line.

I have a friend who has a BX2380. Do they have the same issue? He hasnt used his since he got it, but I would hate for the warranty to run out and then find the problem.

Re: BX loader valve quick connect

It's all the same quick connect manifold so I would say if it is a part issue then his is subject to the same issue.

Re: BX loader valve quick connect

I'm watching this thread closely. The coupler on my 1880 is not easy to attach and lock down. Takes a lot of wiggling and pushing before the lock arm will slide down into place. All the videos I've watched showing the 80 series quick attach make it look simple and easy, mine is definitely not. No leaks from the coupling so far, but I'm keeping a close eye on it. If your dealer is able to fix yours will you please keep us updated?

Re: BX loader valve quick connect

I finally got the leaking issue resolved. The connectors under the manifold had rattled loose and were leaking. Tightened them back up and all is well. You are correct, it takes a fair amount of wiggling and pushing to get the quick connect coupler locked down.

Re: BX loader valve quick connect

It's a hassle for sure. I'd almost prefer the four individual connections from the old design. Maybe it will get easier as it breaks in.

Re: BX loader valve quick connect

I just realized how that new contraption works, connecting all 4 at once. I'm betting that the problem most folks are having with it being hard to get it clamped down is that there's pressure in at least one of the lines, but since you can only do all 4 at once you don''t know which one it is. The old way, with individual quick disconnects, you knew which one had pressure when it was hard to get on, and you could do something about it, like depress the ball or pull or push on a cylinder ram, to relieve the pressure.

That new style is probably even harder if two lines have pressure, as you have to overcome twice the pressure than with a single disconnect.
