[QUOTE="BrianLS180, post: 65682, member: 9126"] Thank you Mike, I must have read your mind... I did just that earlier today and got it working... Well, sort of. I can move the valve spool in and out the only thing that worries me is the o ring because of the pits from the rust I sanded off. I can see a burr or something slicing the o ring and developing a leak later on. I can feel some resistance when it goes in (not out though) and some hydraulic fluid seems to seep out if i go in too far. I looked up removing the control valve in my downloaded service manual and it looks pretty easy to rebuild. May just pull that spool and replace with new and o ring if possible. I need to find a good supplier for new holland parts online if you know of any good ones. Have you ever disassembled the control valve to install new spools/o rings? Looks like the o rings can be done without pulling the whole control valve but I really think the spool should be replaced. The previous owners must have used it to load salt in the winter....
