    Was Plowing Last Night,we got about 10"s.I noticed at 1st the Plow started dropping a Bit Slow?Then it also started Drifting as was going from site to site?And,pretty soon,it would not Drop at all?
    I ran back to my Shop and puuled the Screens and Clened them and got it working again?Only to have the Same Problem again this Morning?But,when i pulled the Screens this Time they were Clean???
    The Only thing that i have found so far,is the Spring in the Cross-over Valve is Busted all to Hell?Could this be the Problem?
    I did change the Drop Solenoid,and that did Not cure the Problem?
    ANY HELP?
    Would be GREATLY APPRECIATED!!!
    THANK YOU
    Greg :dizzy:

    The broken cross over spring will definitely prevent the blade from holding the angle you set it at..

    When you cleaned the screens and it worked temporarily, what was in the screens? Crud or ice?

    When you say that you replaced the "drop solenoid" do you mean just the coil, or the valve, or both?

    Drop

    I took the Drop Valve out and Inspected it and Cleaned it.It did not have anything in the screen?But the screens that are in the frt.on the valve body,2 of them were almost full of(Debree?)Real hard to say what it was?There have been some o-ring issues with the Ram,so maybe some of the Black particals were that?
    I read in a previous Post that behind 1 of the Screens in the frt,of tthe Pump theres a Drop Adjustment?If this port has some JUNK in it,is it possible that this could be the problem?I did Not replace the Valve on the Drop,just the Coil.
    So,yje Crossover Srping is just for the Turn/Cylinders?That makes sence why the Blade would NOT Hold its position?But,has nothing to do with the Drop.
    It looks like my Problem is with the Drop Adjustment Port???
    THANK YOU

    Since you found a lot of debris in it, I'd remove the drop speed screw and the A valve again and blow the passage way out with compressed air... as it does sound like it may be plugged up there...

    The drop speed screw is located behind the 11/16" hex plug that closest to the valve block.. Use a 3/16 allen wrench to remove it...

    You might want to clean the screen on the back side of the pump also, if you haven/t already done so. It's also behind an 11/16" hex plug.

    Make sure the blade is on the ground before you touch either the A valve or the drop speed screw.

    Drop

    THANKS B&B!
    I have an Old 47 on now as a Spare!
    I will try and Repair the 60 tomorrow?
    When the Speed screws move,do they go in and Stop the Flow?I would think that they would back out(NOT IN)but i could have a blocked passage and not a speed screw Issue?
    I woll keep you Posted on My PROGRESS>?
    THANKS
    Again
    Greg

    Usually the drop screws do thread themselves out when they move on their own.. but have seen one or two that went in! All on trucks that the pump was mounted "backward" from normal.

    And do keep us posted on the outcome.
