    For what you paid, they should have been new. Possible, but I don't think so

    Do you notice it moving left only very briefly after you let the raise switch go or is it doing it the whole time you are raising?

    Hi timboy the blade will nudge alittle to the left when raising blade off of ground. Also when blade is angled to right it will slightly go back to straight and if plow is angled to left half way it will push back to almost full left angle ...

    The way these units work is just powering the motor alone angles left,the other functions require coil and valve action to operate,it is not unusual for a meyer power unit to have a slight jerk to the left after running a different function due to the valves closing before the motor has stopped spinning the pump.
    It is most noticable on e57 and e60 with slick stik or toggle switch controllers units due to the larger motors and quicker performance.
    From the additional information you provided in your last reply I'm not sure that is the cause as it seems your blade is moving quit a bit but at least its food for thought.
    Good luck with the dealer,I hope they get it sorted out for you.

    It angles to one side by default. Whey you only have three valves, but four functions, if theres metal in there, bad pump? How are the angle pistons, clean and shinny, or pitted and rusty?

    Well got e47 pump asm back from rebuilder they put new crossover valve in and told me that silver in fluid was never sieze from using on valves when installed . Also they told me it is normal that blade angles slightly left when plow switch is up and held dead headed ....Any one have any comments on the plow angle to left a little as described above

    As stated earlier in posts...that is characteristic of using analog switches....if you don’t want that slight jerk to the left...go to the digital touch pad...it has a built in delay...holding the activated valve open for 500ms after power to the pump is removed....if you do switch to the digital touch pad....a diode has to be added to the under hood relay to prevent a negative spike from feeding back to the controller as the magnetic field collapses at the relay....yes analog switches will tolerate that spike digital won’t.....just joined site so reply may to too late to help....but maybe someone in the future.
