    Is the motor spinning up to it's capacity? Are the grounds good? I would start there.

    Make sure fluid is 1-1 1/2 inches below the fill hole. Also check the filters.

    Does the plow drift down? If it does it could be a bad A valve.

    Ok....the grounds are good and clean also tight. Motor sounds good too me( but im a novice ). Plow does not drift down...it will stay upright for days in a row.it seems like it raises faster with the plow board unhooked...but as soon as a load is on it ....it goes SLOW. I do not have any gauges too put on it so I am out of luck in that reguard.

    Still check both filters. If that isn't the problem afraid to say it may be time for a rebuild.

    Ok...I have checked the filters ...they are clean....ok maybe a stupid question ....but what all is involved with a rebuild? Im asking because I have replaced quite a bit of stuff on this unit already.....thanks.

    I would say a bad valve or an obstruction in the fluid reservoir check for magnetism on the valve that raises the plow. I have an E 60, not sure if they are the same, but. You can also try a new solenoid on that valve.

    Need to tear the compete unit apart and check all parts for wear and clean everything.

    Been awhile since I tore a E47 down, but if I remember correct you cannot tear down the pump like you can with a E60. The 47 pump should be sold as an assembly. With out a gauge it will be hard to tell if the pump is worn or not.

    He is asking to determine if it is the pump or something else.

    In order for the plow to raise only , you need to energize the motor, none of the electronic solenoids on the pump. Just making sure that you aren't activating a solenoid for angle or drop while trying to lift it.
    They really aren't too bad to rebuild, you can download the manual online.

    If I remember correct the E47's default is left. Which means to go up it needs to run the motor and energize the B valve. If only motor is energized the blade should go left.





    To rebuild you tear the entire pump apart cleaning all parts, check any part for wear and replacing any worn parts. You also replace all the seals, master rebuild kit should be around $80. So replacing some of the seals is not rebuilding the unit.

    Have you had a chance to try and run the angling rams? If they are slow also I would bet it is time for a pump. For the E47 it is sold as a assembly. It would be best if you could do a pressure test on the unit. Unfortunately most shops that have a test stand will not hook a used unit to the test stand due to fear of contamination. You can get a gauge and hook it into the angling ram hose to test pressure.

    Another thing you can try is taking the motor of and trying to turn the pump shaft by hand. It should turn pretty easy. Be careful when pulling the motor, it will fall apart and can be a pain to put back together. Also you can try turning the pressure relief up, but I don't recommend doing this with out having a gauge.

    If you have the manual and some mechanical ability you won't have any problems rebuilding it. There are a few parts but as long as you keep track it's not too bad. I try to do one section at a time, take old o-rings off one valve, install new etc.

    The crossover valve is the hardest I think...lol Gotta be patient.
    Maybe the motor is dragging a little or not quite spinning up to it's capabilities, how are you powering it? Hooked to the battery for normal operation? I tried to run one off my bat charger and it wouldn't do it, even on 60 amps.
    good luck.
    There a lot of more qualified people on here than me that will help you if you get in a jam.

    Dave thanks for the help....I may tear into in a few weeks after harvest is over...kinda pinched for time now. And yes im powering it right too the battery for normal operation. I have a two battery set up in my dodge diesel, so I would think there is sufficient power there for it. The batteries are less than two years old.....

    The E47 should draw no more than 100 amps. Most I have seen average around 80 amps.

    Like Dave said the cross over valve is the biggest pain. Not that it is hard to put in, it just has ton of tiny little parts.

    I would suggest that you get everything on the truck and then begin diagnosing it from there. Just too many possibilities right now.
