I have a 560 gas with dual hydraulics plus a fast hitch.
It is equipped with a Koyker K2 loader.
The lifting system for the loader works fine as well as the fast hitch. However the control valve that curls the bucket quit working properly yesterday.
It will not hold it"s position.
I switched the hoses between the systems then the bucket worked fine. So I am to assume that it is the control valve to that system at fault. Is that correct or could it be something else.
The bucket control valve doesn"t work as freely as the lifting control valve. It makes me think there may be a damaged o-ring hindering the movement of the spool.
How do I go about removing and rebuilding the control valve or can it be done with removing it from the tractor.
My shop manual doesn't cover this part if the hydraulic system, it only covers the tele-depth valve which seems to be different.
The control valve for the bucket is the far right unit looking from the seat and the photo I attached. It has a knob for switching from single action to dual action cylinders.
