On my Cherokee it has two slides that are connected in a loop. My pump motor runs but does not pump fluid. In there infinite wisdom the pump is located in a cabinet that you cannot get to with the slide in, there is no outside access as well. My understanding is the only solenoid is for electrical to change directions. Other then low fluid is there anything else to try?

call manufacturer first.. they may be helpful.

u say pump runs? any noise thats different? you could have a sucked air.. its possible to bleed from under neith. some hydraulics you can loosen a hose on high side and see if it squirts when pump on... care ful not to get that fluid in the eye .

if not the preasure side ... possible to loosen suction side.
might even be possible to put hose in a container of fluid to see if it sucks up fluid.

last resort : pull pins that connect hydraulic cylinder and manually pull out slide. heavy rope hooked to pick up and pull ....


when u play in the sand .... you can get stuck

Well I had time to unbolt ram and pull slide out to get to pump. It was 2 quarts low on fluid. Added fluid and bolted ram back on and works fine. Now where did the fluid go? No signs of a leak anywhere. All the hoses are ran under the trailer and no fluid in the pump tray.
