Replace B219 Loader Control Valve
Posted June 20, 2012 - 08:54 PM
Also, as a side question, most of the valves I see that are "ideal for loader control valves" have one port with float. From what I can find online, "float" means that the cylinder is allowed to move at will. Why would you want that on a loader?

Have you done any work on the hydraulic system lately? There might be air in the system. If there is just cycle through the movements a bunch of times and it will work out the air eventually.
I don't think a bad spool would cause that, although I could be wrong.

I would check the linkage between the valve and the lever. It almost sounds to me like that may be your problem rather than the valve itself.

PK Fanatic: Yup, first thing I checked, fluid is full, and fresh. This is the first time I've had any of it apart, and if there was air in the system, I would have long ago worked it out. I've put over 100 hours on it since I got it. about half of it with the loader.
JDBrian: Good call on the float usage, never thought of that. The linkage works smoothly and correctly with no binding.
One thing I did think about, is that the leak is on the valve for the arm control valve, so maybe that does have something to do with it. Gonna get new O-rings today, and see.
One other thing to ask: open center or closed?
Thanks to everyone for their ideas, keep them coming!!
