I have just bought a 7710 ford 4x4 with dual power and two remote valves. Nothing hydraulic works except the 3pt hitch. It works up and down fine with out a load on it ant tried it with a load yet. The pump on the right side of the transmission looks new. The pump on the left side of the motor looks factory. The local dealer said the pump on the trans works the remotes, dp and 4x4 and the pump on the left works the lift only. Is this true everything I find on the internet says opposite. Can anybody tell me without a doubt what pump works what? And when I say nothing works the pto don't turn at all you can grab it and turn in by hand with it engaged or disengaged. The lights switch from turtle to rabbit but is faster in turtle than rabbit. I assume one pump is totally shot. Any help will be greatly appreciated!
