    Ok so I did the usual....put a new filter and fill tube on the pump....went thru the connections on the plow n truck.

    And now my plow will not do any hydraulic functions. I have continuity at the plug, the fuses aren't blown on the controller, And the solenoid is clicking just fine.

    The motor runs, and it doesn't sound like its running dry and it doesn't sound like when a cylinder has hit full stroke. It just won't lift, angle, vee...nada.

    Any ideas????:confused:

    Sounds like the pickup tube came back out.

    I thought so too then I pulled the resevoir tank back off of it and its stilll hanging out of the pump...I hooked my cordless drill on the shaft of the pump and pulled the trigger with the filter in plow oil and it checked out.

    The vee's are notorious for getting air locked after a full drain. Crack a line (start with the lift cylinder) and run that function to bleed it. Work your way through the functions and it should come to life. Be careful you don't run it dry.

    I loosened up one of the fittings and got no fluid..not even bubbles. So I had the dealer check the controller. The mechanic tested it out and it was fine. So I went through my mechanic guide....pulled the wires off a coil and hooked my ohmmeter up to it. It was getting juice. Which meant one thing....I had the pump in backwards.

    How did you manage to put it in backwards?

    I suppose if he actually unbolted the pump from the valve, he could have oriented it incorrectly when he reinstalled it so that the output port didn't align correctly with the valve, and it couldn't pump oil to the valve. :confused: I think the bolt arrangement for attaching the pump is just four bolts in a square pattern, so it seems possible to bolt it on while it's turned in the wrong position... maybe?
