Bt 900 still not working

[thessler]

Hi
I just bought this tractor with a bt 900 backhoe attached.
I have posted before on this problem and have tried suggestions.
The swing pistons don't work much, they will move the backhoe to about 45 degrees in either direction and then the arm just moves back to the middle while still holding the control to the direction I want it to go in.
I have switched the lines on the control body to a different value and get the same results. I have just finished re sealing both swing pistons and it made no difference.
I have no idea where to go from here.
Any help greatly appreciated.
Thanks, Tom

Recently someone was posting about an auto return feature on a backhoe which was irritating him and he was looking for a way to defeat this.

Could your hoe also have this feature?

If you think you might have an auto return these images showing details of the system and wiring diagram might help.
