Hello all. New to the forum and trying to figure out how to navigate so bear with me please.
I've got a 2007 Kubota BX1850 with an LA240 loader attachment.
The loader/bucket recently began losing capacity, and bleeding down. When we raise the bucket and let go of the stick, it drops a few inches and then slowly bleeds down.
Same issue with bucket curl. Bucket curl lost capacity and will also bleed down. (Bucket will dump on it's own, loader will drop on its own).
Mower deck and three point do not appear to have bleeding issue. Seems to be isolated to loader bucket.
My first task was to change the HST oil and spin on filter and clean out the mesh filter to see what I could see.
What I found when I cleaned the mesh filter was what looked like little strips of blue latex paint in it. Like what you would see when cleaning a paint brush after using it.
So I think I have a blown seal somewhere in the system, (probably a BLUE one, right?)
My first thought was that since both lift / curl functions are affected, it might be in the control valve that the joystick is connected to. That part is about $900 w/ freight, and even with schematics showing me where it is, I'm not sure I'm up to the task!
So I think some more and realize that there are only three cylinders on the loader, but there are four hydraulic lines that I hook up when connecting the loader to the tractor.
I say all of that, to ask this question:
Is one of the four hydraulic lines to the loader "common" to all three cylinders? (Two lift, one bucket curl).
My thought process is going like this: If one of the four lines is a common return line and one of the three cylinders has blown a seal....could that one cylinder not cause all three cylinders to bleed?
Is that a sound thought process? If so, any tips on determining which cylinder is bad without tearing apart/rebuilding all three?
Any help would be greatly appreciated.
Control valve - $900 (not sure I'm capable)
Seal kits to rebuild all three cylinders $250 (THIS I can do!)
Take it to the dealership to repair - $????.??
