extra hydraulic valve

Posted by Dan Wa on February 19, 2004 at 21:27:52 from (12.160.171.186):

I have a SMTA with a "christmas tree" type remote velve. I use it to operate the 3 point on the tractor but I need another valve to turn a roll over type plow. I realized with the open center system the valves had to be in series. Originally the pressure line tee d to the remote valve pressure port then went to the inlet of the lift all. Return line goes from the lift all ant Ts to the return from the remote. This seemed to be original IH setup, remote worked fine as long as lift all lever locked back. I added another single spool open center remote valve on the side on the battery box. I removed the T in the pressure line from the inlet of the original remote. I put a t in the pressure line near the lift all inlet and ran to the inlet of the new valve. hose from the outlet of the new valve went to the inlet of the IH valve. Left return as it was. When you pulled back on IH valve, handle would lift on other remote valve. If you had weight on the 3 point, from the IH valve, it would not lift unless you held the other valve handle down. I replumbed it with the pressure line going to IH valve, outlet of IH valve goes to inlet of other valve, outlet of other valve goes to inlet of lift all housing. Return line from liftall goes to pump. At first would lift 3 point but very slowly, ih valve handle fell into foreward position when you get go of it. I filled lift all box. Now does not lift 3 point, actls like no pressure for a bit then will labor and pressure line tightens, valve handle hard to move. I am wondering if it may be a volume issue as I ran a 1/2 inch line from outlet of ih valve to new valve and 1/2 inch line to lift all. Am I not getting enough oil through system? Needing help!!!!!
