Hiniker Plow settles down while driving

    Last season plowing I ran up against a concrete lip, that the trip springs absorbed pretty well. Since hitting the concrete my Hiniker 7.5' tends to settle or slowly drop. I replaced the spring and ball for the relief and also the down solenoid on the pump. I can unplug the joystick controller, and it still settles. I don't like running down the road continuously lifting the blade. I do not see any oil residue leaking from the lift ram, if the seals were bad. Any help or ideas what to check next?

    Thanks for the help,
    Mark

    I should clarify, I replaced the valve body, but not the coil. I said it was the solenoid. Could it be a weak coil on the down side?



    Thanks Iplowsno, I wont mention what happens with you on HCS

    do mean the valve itself? you would want to replace the up valve, not the down.

    I don't know? I looked at the trouble shooting pages of the manual, here is what that says:

    Model: 2752
    Plow does not remain raised with joystick in neutral position:

    A. Leakage through pump check valve
    B. Leakage through solenoid lowering valve
    C. Internal leakage in cylinder
    D. Defective joystick control

    Still slowly settles. May have to lift it every 1 1/2 miles as I drive down the road. Sometimes faster than others. Only on the road a few miles at a time anyways. I just need to be careful when I reach for the joy stick.

    Mine does that last year for a week or 2. When it does that, I just lift it up and turn left and right fully then centered it up. It will stop tryin to settle down slowly. I didn't do any repairs on it yet because right now it doesn't do it anymore. I assume it could be sticking valves but who knows. It worked just fine for now. But I guess when I have time I should drain and flush the hydraulic oil and put in new oil someday and hopefully it should take care of it.

    Well after some time, the plow would have streaks, when it stayed raised and others when it would settle. Today it kept settling fast,so I tore into it. All the problems were caused by a cracked "O" ring seal on the check valve assembly. Replaced that, and the plow stays lifted.

    I would like to thank the tech I talked to at Toppers Plus today in Mankato, telling me where to find the problem.

    Bridgebuster,

    I found that on the top of the pump, there is a ported block that screws down to the pump assembly. (check Valve assembly) There were 2-3 small O-Rings, with one bad. I replaced them, and the plow stays up rock solid. This I fixed last winter, so I don't remember all the details. I would need to look at a drawing to point them out exactly.
    Best of Luck,
    Mark
