    The plow worked great last year but this year it gets stuck when I angle all the way to the left. I have to play with the joy stick or wait for a minute to get it unstuck. When it was stuck I unbolted the cylinders and the plow moved very easy side to side with one hand. I even moved the right cylinder to the left and the left cylinder to the right and it still got stuck in the far left position. If I stop the left angle before it hits the stop it nevers gets stuck. When I was unbolting the cylinders when it was stuck the right cylinder had alot of pressure in it was hard to get the bolt out of it. do you guys think the C valve or cross over valve could be the problem?
    Thanks

    Thanks for the information should I get the C valve and the magnet too. Also the cross over valve should I replace all of them at the same time? Would the 2 filters give me this problem if they were dirty?
    Thanks again jeep2001

    9 out of 10 times it is the C valve causing this. You can start by removing C coil. If it is difficult to remove the valve is swollen and damaged.

    Cross over valves? Unless you have a very old version it should only have one cross over. If anything you can try lower the relief setting a bit to see if that helps but may allow plow to swing while plowing.

    The last thing to check is that the pilot check moves freely and what quick connects you have. The ones with the balls are known to cause all kinds of issues. The ones with pins are the ones you want. This theory can be checked by removing quick connects and attaching hoses directly to the pump.

    make sure the power is going thru the switch if a slick stick..

    Thanks everyone for the information. I will replace the C valve. I am not sure how to check the pilot can you explain more on this. My quick connects are the one with the balls so I will try it without the quick connect on it. The slick stick gave me trouble a couple years ago but it was fine last year. When the plow was getting stuck I put a test light on the C coil and I was getting power to it when I was trying to angle right and pump motor was running. How can I tell if I have a very old edition of the E47.
    Thanks

    easiest way to check the coil is to stick a screw driver inside it and have someone angle the stick. If you have magnatisim, then the coil is good, if not, then start back tracing

    Post a pic. Early PA blocks had two cross over valves. All you need to do to test for magnetism is a screw driver or wrench against the nut on top. you will feel the magnetism.

    Old style Meyer coils ground through the top bolt so removing to test them will not work.

    Thanks guys, l am planning to remove the C valve tomorrow and check the coil too. I seen a seal kit for the C valve but would I be better off just to replace the C valve and coil. I will post a picture of the PA block. Can you recommend a place to get parts from? Thanks

    Thanks, I should have power to the C valve when the controller is put into right angle position. When controller is put into left angle position I should have no power to C valve. Is this correct, I am getting some pictures of the E 47 today to post.
    Thanks

    Stops worn off of the sector/a-frame can also cause this issue , when angling the ram will over collapse and block the inlet port not allowing fluid to extend the ram. Easiest check for this is to temporarily tape a nut or small piece of steel to the A frame where the plow hits when it angles , do it for both sides , if the plow works normally now have these pieces welded on and the problem will be solved . They do not usually need to be that thick either , about an 1/8" or so will usually do it . Also , quick couplers can and will fail over time , allowing fluid to pass in one direction but not easily in the other , it might be time to swap them out if they have some age .

    Thanks for the information, I will try this tomorrow with the stops. I checked the C coil today and I can feel the magnetism. I did notice today after I angled the plow all the way to the left and of course the plow always got stuck there, but if I waited 10 seconds without touching the control l could angle the plow the other way with no problem at all. I didn't get a chance to bypass the quick couplers yet. If I remove the C valve is there anyway by looking at it to tell if it's bad. I like to thank everybody for the excellent advice, here are some pictures of my E 47 it looks like it might have 2 cross over valves but I'm not sure.
    Thanks

    I tape a nut about 7/16 wide on the stop today, and it seemed better but not perfect. Then l removed the nut and tried it again. It was a little better than yesterday it seems now it only gets stuck if you still have the switch push 1 or 2 seconds after the plow hits the left stop. Maybe something to do with excessive pressure buildup? I am going to order the C valve and Quick connect ends this weekend. I was wondering what kind of sealant should I put on the threaded part of the quick connects.
    Thanks
