    I have a E60H set up that does everything its supposed to except it doesnt hold an angle in both directions. I can even move the blade from side to side by grabbing it and pushing on it. The fluid was changed recently with the correct fluid and is full. What does this sound like and what should I check? thanks

    you need to check your cross over relief valve. One of the 2 o-rings may have given out, or the spring broke (usually due to lack of use/lubrication). You can purchase a rebuild kit for it, or purchase the new one piece cross over Meyer makes for the new P/A blocks. It will work in the older ones such as the block in your E-60H.

    Did it work before you changed the fluid? If so, you may have air in it and you will have to bleed it out. Get the blade lower than the truck and work it left and right to force it out.

    Yes, it did work before I changed the fluid. I filled it up several times as the fluid was low and it seemed to help but after being ful it still wont hold an angle. I will try bleeding it.

    Had a similar problem but would not hold in one direction. Kimber750 led me in the right direction.. also look at the piolot check valve and the ball and spring under that check valve. I had to take a brass punch and reset the ball into the seat. Put it back together and it held. With yours not holding in both direction would do as stated by fourtrax look at that cross over valve

    definitely sounds like you have air in the cylinders. What I did the other day bleed the air out was park my truck in my driveway which is higher than the street, I then dropped the blade on the street and ran it lock to lock about 3 times and that did the trick.

    Ok, I will try that trick and see if it fixes it and report back as I also believe that sounds like the problem.

    I put the plow in float mode and fully compressed the lift ram by hand then angled the plow back and forth 4 or 5 times to no effect. Is that what you mean?

    not the lift ram, you need to get the angle pistons at an angle so that the end of the ram where the fittings are is the highest point on the ram. Off the edge of a driveway, or as I did during a storm today, off the embankment of a stream next to a parking lot, then run the blade back and forth. If there is air in the pistons, you want that all the way at the top, and the only way to do that is to have the rams like I stated

    Mwalch. I tried what you said, got on a steep incline and the truck pointed down and worked the plow back and forth repeatadly, it cured it great except for it has a couple of inches of freeplay before the rams lock up. Any suggestions?

    check your fluid level and try it again? Usually mine only takes about 30 seconds tops to purge the air out
