    I have an Monarch 693 pump on an older LZ plow, and right now, it will not swing to the right. I have 4 valves on the firewall end, position 3,6, & 9 are the same size, but the one at 12 is larger. I have been told the large one is the 'right swing' that is bad, but the valve tip pushes in and pops out immediately, as I have taken it out and cleaned it several times.

    I have switched the magnets on the other three, and this does not switch the problem, still no right swing. This is driving me nuts...I am NOT a plow expert....

    Any help or info to get a diagram for this pump would be appreciated....VERY much.

    I can be reached here at sser@somtel.net, or my cell 715-760-0738....I would love to talk to anyone with some info, and I can call you...if that works cheaper for you....
