Guest Posted March 3, 2007 Here are the parts that fixed the bleed down of my two spool valves. Both the loader and the three point hitch valve take the same parts. Note the two slotted plugs. This is where the above parts go. Also inspect the spool valve seats. Take a Dremel with a fine wire brush & clean up the seats if required. Share this post Link to post Share on other sites
PGL 424 Posted March 3, 2007 My tractor/loader are being stored up north for the winter, but based on my recollection, that looks like the spool valves for my 600 loader. If so, it looks like you got the parts from an AC/Simplicity dealer - are they expensive? Would it be possible to do the overhaul right on the tractor or are there other parts and steps that make it preferable to remove the assembly as you did?

Guest Posted March 3, 2007 About $25 for all the parts. You can install all on the tractor. I did not remove the spool valve. The picture is a spare valve. Share this post Link to post Share on other sites
