I think I know the answer to this already but I want to ask anyway. Long story but the end result is a Kubota rep said my main pressure relief valve is stuck open and I am only running on bypass hydraulics. After looking at the control valve, my question is: will I need to completely undo every hydraulic line on the control valve and the remove the whole unit to clean out and unstick my relief valve? looks like I will but will appreciate any info or thoughts on this before I start this project. Anxious to have full power back again.
Thanks for the help.
