Kubota la524 loader float control problems

[Codom]

The mounting bracket for my kubota la524 loader broke the other day. After welding the bracket up. I reinstalled it on the tractor. I did not remove any lines from the pump. Now my float control is reversed. Anyone have this problem. Again I did not remove any lines what's so ever. Only the bracket.

Float is a detented position on the valve-you get to it by pushing the joystick fully forwards (or up on some loader because of the way the valve is mounted on the tower).

How can it be "reversed"?

I'm calling it reverse but now whenever I pick the tires up off the ground and you push the lever to much it slams the tractor back down this never happen before?

What you describe here is a loader valve working properly. When you say you push the lever "to much" that is the float position. Just what it's suppose to do!

Thanks for that info and i appreciate everyones thoughts. However I am aware of the float control and it's purpose. The float control was working fine before I removed the bracket. After I reinstalled the mounting bracket that the hydraulic control valve sits on. The float position is not the same as it was before. I even went to my dad's house and my neighbors house and got on there tractors just to make sure I wasn't going crazy. And something is definitely not right. Whenever scooping dirt or pushing something with the bucket the float control is not activated in the same position as before. I did not unhook any hydraulic lines what's so ever. I only removed the bracket & welded it back up and reinstalled it. I assumed the same way as before? Thanks again

Thinking the detent part has been disturbed, water or moisture will get in and rust the balls and spring. Maybe by letting it hang or using a hammer/impact near valve knocked something loose.

Well you've done a good job of not getting the answer you need. How about taking a picture of the bracket you welded, and then one of your control valve.

What you described as doing (welding a bracket) should not have an effect on how a control valve functions.

You say, " The float position is not the same as it was before."

Maybe it wasn't working correctly before you did your work, and now it is...and you're not use to it working that way? Did the bracket you welded have anything to do with the physical position of the control valve?

Here are some pictures.

Some more sorry couldn't get but one at a time to load.

This is the bottom of the bracket that broke. It just had 2 small tack welds on it.

Is this (circled in blue) the part you welded?

If so, shifting the exact position even slightly will make a difference in the point that the functions actuate when multiplied by the lever length.

This is the bracket I welded. I never unhooked any of the those lines except for the bolt that holds the lever in place.

Does anyone know of link that has a digram of the LA524 FEL. I've search online and have failed to find anything.

If something worked before one takes action, but fails to work after said action, then the first rule of troubleshooting applies: "What did you do?"

This is the bracket I welded. I never unhooked any of the those lines except for the bolt that holds the lever in place.

Is there some way that the bolt can affect the throw of the lever or the location of the fulcrum? If you look at the amount of shiny spot on the spool valve and compare that to the travel at the end of the lever, I imagine you will discover that it would not take much change in alignment to make a noticeable change at the lever.

Not sure what happen when I put it back together but after adjusting the tension on the control valve it is back to where it was before. Thanks for the help and everyone's input.

aaaand that would be why it is the first rule of troubleshooting!


For future reference, the second rule of troubleshooting is: "Try the easiest and simplest possibility first, because it doesn't take much time or money to try and it is usually the problem anyway."
