    Scratching my head on this one. Converted a e47 to a 57 new pump, new motor, new valves and coils. Did not get to use it last year because not any snow last year in the kansas city area. But this year after this big storm the plow will angle left (passeger side extended) and it will hold. Angle to the right (driver side ram extended) the plow will move back with little pressure put on the plow. Changed the seals on the C valvle like the book said nothing, replaced the seals on the crossover valve like the book said, nothing , replaced the C vavle just to make sure, nothing still moves. Put on a new block like the book said, fixed the problem. I just want to know why this is. looked in book looks like a check ball that is in the block that you can not replace, but it looks like if that check ball and spring was bad, it wood allow the plow to move in both direction, just wood like to know what is going on, is there a hole block?

    I would check the pilot check ball. This is what stops the fluid from leaving the drivers side ram. Pilot check ball does not effect the passenger side ram unless C valve is energized to allow fluid to go that direction. There is a plug on the bottom of PA block that will allow access to pilot check ball.

    Edit, also make sure pilot piston moves freely.

    I had a similar problem with my E60 when I got it, and after trying everything B&B told me to check my check ball....and it was missing

    forgot to mention, put in a new pilot , but not the ball. Does the ball go bad? Would not think it would but could be wrong.

    Normally I see the pilot stuck but rust or any damage on the check ball can allow fluid to get past.

    Kimber thanks for the info and sorry for so long getting back to. Been off work because of snow storm. I installed a new check ball and spring because we did find a bad spot on the old check ball.

    But still not holding. Going to take out the pilot check valve, and look inside while having someone move the plow and see if fluid is still leaking past the check ball, maybe the seat where the check ball seals is bad and need a new block ....

    You can try seating the new ball with a brass drift and a few sharp whacks with a hammer. Don't get too crazy.
