No Float on Kub 4 Way Loader Valve

[Bucky4]

The 4-way valve float position is not working on my LA723 loader. (Kub Grand L3130)

Although I don't use it that often, I'd still like to repair it. Does the valve need replaced/rebuilt or could it be something else? What's a ballpark $ figure for a new valve or a rebuild?

Thanks,
Jim

I had the same problem with mine while under warranty. It had water in the valve. They changed a part in the loader valve and it works like new. It was a 2 minute fix at the dealer........

Hey John, thanks for the reply. I believe mine may have the same problem as the valve froze when the temps dropped this past winter. (i.e., could not be moved until warmed up)

Do you (or anyone else) know what they replaced in the valve or what the dealer did to it? Mine is not under warranty so I gotta do it myself.

Your dealers parts dept should be ableto give you a copy of the parts break down. I'd recommend that you have it when you take the cap off as the balls and the spring might be laying in it. We fill the caps with grease before installation.

Just drill a very small hole in the aluminum cover that retains the spring...... it will allow the moisture to drain and you can also use the hole to pray lube up in there.

OK, I take the cover off and now what do I do? I'm going to assume that you mean the balls and spring are supposed be someplace else besides inside the cap. Is there something inside the valve that needs replaced?

What is the purpose of the grease in the cap?

Still !!!

This is not the fix but just a slight design change for preventive maintenance after the valve has been repaired, right?

When I took it to the dealer under warranty they replaced the Chrome looking unit of the valve body. It was actually grey { the original but was replaced with the new one. As you can see there is a small diameter hole in the bottom of the Nut. When they unscrewed the original water came out of the body. Replaced with no questions asked. 1 minute fix. unscrew yours and i'm sure water will come out of it. Sorry for the delay but had no pics of the replaced part. Hope this helps........This is the underside of the joystick control looking at it from the front.......

JK,

Thanks so much for the information and the pics! You da man!!

Now I understand what Ductape was saying about drilling a small hole.

Still don't understand the reason Art says to fill the cap with grease. Is this a "fix" instead of drilling the hole?

I think the grease just holds everything together while it is assembled. Little check balls and springs have a habit of running away and hiding .
