We have an older Yanmar trackhoe. Blew up the pump. Rebuilt it, now the controls don't work. Perhaps some trash in the control bank somewhere? We unhooked a line at the control bank and have line pressure so the pump is working.
Where would the relief valve be in that older system? I am thinking maybe some trash from the pump is keeping a relief valve open and the control bank is starving for oil. We replaced the oil with new and filters are new.
Need help in Georgia!
