I have a DP 290 with hyd / power steering. This is a pain to get to however finally trying to diagnose why power not working pulled everything apart and hooked hoses to the actuator , moved the shuttle valve back and forth w the diesel running , integral ram working perfectly !!! Now for my quandary and I hope there is something missing or just some pat of this I am not Not understanding? I do not see how? This system can works the valve back and forth to make the fluid go to the ram? Does somebody have a schematic or explanation ? Any thing greatly appreciated. This is a great mystery . Folks have said there. Is not much difference w the power and just the hyd ! I am considering using the power steering pump for just a pot puller !
