    Alright heres the deal the last storm i was try to clear a lot and i hooked a curb as i was backing up. i didn't think anything of it till i tryed to put it into a straight blade and it wouldnt move. one of the nuts on the end of the right side ram had come lose. after fixing the leak and toping off the fluid it still sound like the pump is out of fluid when i put it into a scoop does anyone have any ideas.

    You might of gotten an air bubble in the ram when the nut came off. I'd check the levels again n see where you are at.

    I had the same problem with mine.....pump sounding like it was running out of fluid so I squirted a little extra in there and haven't had a problem since.

    I know its probably a stretch but depending how hard you clipped the curb (or even coincidentally) the pickup tube may have fell off inside the resevoir. Mine fell off earlier this year and even though it was full, it sounded like it was low on fluid.

    Honestly I'm not 100% sure. I bought it earlier this summer and I was told it is 2 years old. Its an Ultramount, but not a MVP Plus.

    maybe the O ring In the ram nut Is spilt....I have also gone through 1, "O" ring in the wing cylinder

    I would check that

    When you topped off the fluid did you crack open the front cap (The grey one) I did this and a burst of air came out and the scoop worked fine.

    the nut only came out about a half of a turn so there wasnt much to see and its not leaking now

    That is EXACTLY what mine was doing when the pickup tube fell off inside the fluid resevoir. Pull it off and check. Its held on by 4 bolts that screw up into the housing.

    What happens is when the pickup falls off, the pump is sucking fluid off the top instead of down in the bottom of the resevoir. Therefore, when you are in scoop and you try to raise the plow, or vica versa, all 3 cylinders on the plow are extended. When the cylinders are extended they are full of fluid and the resevoir is now low on fluid and with no pickup inside its sucking air. This explains why there is excess pressure in your system and also as to why your fluid is foamy.

    Hope this helps.

    B&B told me last year I think that there was a problem with the old pickup tube. I was having the same problems. Bubbly foamy fluid.....turns out the supplier sold crappy parts to western. So I got a new tube kit and works like a champ.


    I don't think the newer MVP pluses would have that problem but you never know. I always keep a couple of those kits handy just in case. If those O rings go bad that can create nightmares and its a simple fix.

    If it'll extend the wings all but the last few inches then either the pickup fell off in the reservoir when you hit the curb, or it's still got air in it.. the MVP's are one of the hardest plow's I've ever worked on to get all the air out of the wing rams....
