SOLVED: FEL not curling down properly

[oakhilltop]

I had previously posted this in another forum and it was suggested that I post this in Hydraulics.

I have a JD 2305 with a 200CX front end loader. Recently, when I attempt to curl the bucket down to dump a load, the FEL curls upwards. I can get it to curl down if I do not push the joystick fully to the right. But it goes much slower and if I push it too far it curls upward and I have to start over. Does anyone know what the cause of this could be? My guess is that there is some vale that controls which hose the fluid goes to and that valve is deteriorating. The tractor and FEL were purchased in 2009 and has the optional valve that allows switching between the FEL and the mowing deck. I have not used that valve for a few years because I've been mowing with another piece of equipment.

A responder in the other thread asked if the FEL has regen on curl/dump and I don't know the answer to that. I do not know what regen is. My apologies.

I read this when you posted, but couldn't think of what might do this. Now reading it, I'm wondering if the linkage might be loose

Thanks for the reply. Are you referring to the linkage on the FEL? I have been wondering if it is the FEL or the controls on the tractor. I will be putting the snowblower on in a couple of weeks (or sooner). The chute rotation is controlled by the same hydraulic lines, so I will see if the chute rotates properly.

I'm referring to the linkage. I thought maybe it could be the cab on the opposite end of the spool valve could be loose, but that usually doesn't allow the valve to center to neutral causing a particular circuit to drift.

I agree with tractor tech to check linkage between the joystick and directional valve. Nothing in the valve itself should cause that movement problem

I do think that it is the linkage. It worked good enough for the snowblower chute this winter. I took off the snowblower today and hooked up the JD CX200 FEL. The bucket is now stuck in the curled down position and will not curl at all. The bucket does go up and down. I have a valve that allows the use of the mowing deck when the FEL is on. The joystick movements that curl the FEL raise and lower the mowing deck. I set the valve in the mower position and the joystick does raise and lower the brackets for the mowing deck. So, I don't think that my current problem is the linkage even though it needs adjustment.

I disconnected and re-connected the hydraulic lines, but that didn't help. The loader was working when I took it off at the start of the winter.

I don't know where to go from here. Any ideas would be appreciated.

Did you get the lines crossed when reinstalling the loader after removing the blower?

 

[oakhilltop]

I just checked and they appear to be correct. I did have to use a relief tool to get a couple of the hoses to go on.

Try changing / swapping the two lines for curl dump to see if problem still persists.

Did you try turning it off and then turning it back on again?
