You might want to pull the lines off the valve, and pressure check them before changing the valve. I say this because I have never seen a valve 'go bad' whether it was a solenoid activated one, or a manual one, to a point it could sent fluid up both ways at the same time.

More than likely the problem is the same thing I recently repaired on a customers dump, and that is the piston seal inside the cylinder is bad. In that case the fluid in the cylinder is simply bypassing the piston and not creating enough force to dump. Often times there will be enough force created to dump with no, or a light, load, depending on how bad the seal has gotten. However, with no more than a 2 inch cylinder to start with, it wouldn't take much for it not to work at all. Most dump cylinders tend to be at least 3 to 4 inch or bigger. In fact I can't ever remember seeing a cylinder that small on a dump, of any kind, unless it was twined with another one.

Like I said, I'd raise and block the bed, pull the lines loose, and check the pressure on both sides. I think you'll find the valve is OK, and the problem lies with what will probably be a bad piston seal. Given the compounds they are often made of, I wouldn't doubt you finding that the seal is completely gone, just like I found the other day in two small cylinders I pulled of a wheel lift wrecker for a guy. Again, even they still halfway worked, just not with a load.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o ... [Read Article]
