So I went hook up my “used” Seastar Hydraulic Steering tonight and started the bleeding process. Hoses were hooked port to starboard and starboard to port. Starting adding fluid to the helm and started the bleeding process. The motor would turn right fine so we started bleeding going back to the left but the cylinder will not turn left at all. We had fluid coming out of the bleed valve and shut it off but motor still would not turn. If I cracked both of the bleed valves the motor would turn left but one either one of the valves were shut it wouldn’t turn anymore. I’m sure I may still have air in the line somewhere, or I have been reading that a ball in one of the valves could be stuck not letting fluid go through. Any help would be great.
