    I have a 8' pro plow ultra mount on a 05 Ford f250 diesel. I ran it the last two days and it worked great. Went out today and it won't angle to the right. Sometimes it will work but it is really slow. It goes up and down fine and when it does go right it angles back to the left fine. Any suggestions.

    S2 or S3 cartridge, or the coil that operates it. I'm sure others will chime in about ground, controller, etc.

    I'm saying this from experience, as it doesn't take much contamination to plug a valve orifice, and although you can quickly check for faulty grounds or a bad controller, you can just as quickly (5-10 minutes) remove a cartridge and test it.

    What's the issue? Is the spool broken?

    Yeah, that's sheared off. Well, they're only $50 per, and you got right to the problem. :salute:

    Ok I put a new s3 cartridge in and it all works, but if I do any angling in the up position to get it to go down I have to hit it up first. When I do that it jumps to the left a little. I can also push my blade to the right by hand like it don't have any pressure on it. A little more help please.

    going to ask if you looked all around inside the valve body???
    if you can push the blade by hand,,,,either the valve is hanging open or your relief valve if being held open

    ATF shouldn't be a problem. Only when it's really cold, it will coagulate, making your plow move slowly. Provided your ram isn't defective (packing nut too tight, hose or fitting clogged), it may be time to dismantle the manifold and give it a thorough cleaning. I just had a similar problem with one of my plows. After twice cleaning the filter and reservoir and changing most of the fluid, I keep getting debris in the fluid (in otherwise virgin fluid). It doesn't take much to clog a valve. Don't forget, you have not only the S1, S2 and S3 valves, but also the poppet valve and cushion valve.

    I cannot remove the crossover relief w/o placing the manifold on the bench. So, I will now:
    1: dismantle the manifold;
    2: flush and clean the reservoir and filter;
    3: flush and clean the rams; and,
    4: dismantle the manifold completely, flush and clean and replace any necessary parts (poppet valves, cushion valve, S1, S2 and S3 valves.

    I have come to the resolution after twice cleaning, the debris is probably coming from the rams. When the plow hits the snow pile at the end of a plow, even if hit lightly, the blade doesn't move...for a reason: the crossover valve is opening, relieving the pressure...as it should. The problem is, if there is debris in the rams, it can find its' way back up to the system. I have never flushed the rams, and I believe debris is now [occasionally] working its' way up into the manifold and reservoir. The good news is, this ought to take care of the system for five or more years, other than your normal annual fluid replacement, and occasional parts replacement (coil or cartridge).
