I recently picked up an L235 with an L1200 loader and a 4530B backhoe. Hydraulics were a mess. The machine had been flipped and the main hydraulic pipe was cut and spliced directly to the loader control. Found a used pipe and replaced. The loader still worked fine. The lift arm control valve was set off in the lock position. Turned it on and arms work, but keep floating up and now there is no pressure to the loader. It seems like the control valve is sticking. I do not see a relief valve on the schematic parts. Only 700 hours on the unit with a new hydraulic pump. Any ideas what to clean/disassemble to fix the issue.
