    Go figure, first money storm of the year and the plow craps out. I've got a 2001 Meyers/Diamond E60H Raise/ lower modes starting getting noticably slower, then erratic, work, not work etc. Angle mode works as it should with good speed, and power.
    I also noticed the plow started to creep down very slowly when traveling blade up. Finally, today in the middle of the storm it quit going up altogether. To make things more interesting, when you press the raise button everything works, the solenoid, motor, and the piston will extend till it gets the slack out of the lift chain, then it just won't lift the plow. I tried adjusting the check valve to no avail. I recently replaced the "B" valve (lift). I checked the filters,check valve, pilot valve, and everything that it said in the manual. I'm leaning toward the theory of the "A" valve(down) sticking slightly open allowing incoming oil to blow right thru the circuit. Anybody got any ideas before I drop another $100 on the A-Valve. Thanks Frank K.

    Pulled the A-valve today, it actually fell apart in my hand, the screen and plunger stayed in the bore and the top came out. Replaced it, and it still made no difference. Tomorrow, we get the seal kit and repack the ram. Another Meyers Guy said to empty the oil out of the sump and clean the crud out of the bottom. He said his low pressure feed to the pump/valves became clogged the pump was not getting a sufficient supply of oil to make it go up. But if that was the case why would the angle pistons work as they should? Thanks Guys, for your help. I'll keep you posted.

    I replaced the A-Valve because it came apart and the screen became dislodged from the valve body. The pump doesn't overload, it sounds exactly the same as when its operating the angle cylinders. It doesn't "scream" it doesn't labor excessively. The more I think of it the more I think the packing in the lift ram, or the O-Ring in the bottom of the ram are shot.
