Boom control fro a Kubota LA 650

[ron winterhoff]

Anybody have a though how much it would be to replace the whole control from the joy stick down as i think that is my problem . The boom goes up but just goes down a little at a time you have to keep tapping the joystick a little at a time . We have got a rebuild kit and did that help no luck rebuilt the two hydraulic cylinders that raise it up are down no luck . The bucket it self works fine it's just the boom . Changed fulids and filters no luck

While people will think of the control valve in the first place when they have issues with the movement of the loader, it's very very rare for a control valve to go bad.

What happens most of the times, is the quick disconnects popping out while still looking fully seated or going bad inside.

Have you tried swapping the curl hoses with the lift hoses on the control valve to see if the issue stays on the same spool or if it changes to the other spool on the control valve?
