Big improvement for a little work since it already had a dual spool valve on it. Problem is, there seems to be no relief valve, or if there is one it's stuck. If you tilt the bucket all the way one way or the other and don't let off the lever the pump dead heads and kills the tractor instantly. Obviously not the ideal situation. Can I add a relief valve, or if there's one built in, how can I fix it? This is a 9N with a front mounted pump and a Wagner spool. The loader is not a Wagner and does not have down pressure, so it's hard to tell if the other spool does the same. [Reply]   [No Email]

Now I can at least do a little reading and see what's going on. I don't think the pressure relief is working on that side, but that side has not been used in who knows how long. It was mounted on this trip bucket loader when I bought it and of course only had one hose hooked up for lift. I'll let you know what I find. [Reply]  [No Email]

He's home so I'll go over and see what we come up with. Can you give me a source for that inline relief valve just in case? Thanks again. [Reply]  [No Email]

If that has always worked then there is a relief somewhere. TOH [Reply]  [No Email]

Yes, both spools are DA, and one work port is plugged. It was that way when I bought it and passed it on to my brother. That is the side hooked to the raise only arm cylinders. [Reply]  [No Email]

Maybe it's too old to have one, maybe it just doesn't work. Mine on my Jube is similar, and I do not have this problem. Here's a pic of the old valve, maybe it will help someone tell me if it has one or not, and if it does, how to fix it. If it doesn't have one, I'll probably go with one of TOH's suggestions to add one. Need a picrure from the top and other end. That looks like both spools are double acting and one work port is plugged - not a good idea especially if there is no relief in the system!!! TOH PS> No need for thread sealant on pipe swivels - the threads are not where the seal is made. This post was edited by TheOldHokie at 18:32:42 08/04/12. [Reply]  [No Email]

It has three ports and goes between the pump and the valve. It limits the pressure the valve will see and hence protects all the work circuits and any downline equipment equally. Pump goes to IN on the relief, OUT from the relief goes to IN on the control valve, and RTN on the relief goes to the reservoir on the loader. You may be able to mount it directly on the IN port of the valve with a hydraulic nipple. TOH [Reply]  [No Email]

This may be a dumb question, but wouldn't I need an in line relief in each line since it's a dual acting cylinder? Other than killing the tractor or blowing a line, what are the dangers? Brother is an even bigger tightwad than I am, so getting him to spend the money will be like pulling hen's teeth. [Reply]  [No Email]

(IL), 08-04-2012 14:08:44   Quoting Removed, click Modern View to see An inline relief valve runs about $45 and requires a separate return line to the sump. A new control valve with internal relief at $150 is another solution and doesn't require the return line. By the time you buy the plumbing for the external valve you are getting close to the cost of the new control valve. TOH [Reply]  [No Email]
