I am a noob to tractor ownership, and my first tractor is a recently purchased 1966 Ford 4000. Overall it is in great shape, but it does have a persistent hydraulic leak around the lower tube (the IT Shop Manual term for it) that is located at the bottom of the flow control valve on the right side. I suspect it is a worn out "o'ring problem, but am wondering how difficult a fix is it? Does it require splitting the tractor, or can you simply remove the two valve plates that the tube fits between? I tried to post a picture of the leak, but the Forum says my account is too new to post. Thanks in advance for the advice.

Upper plate is the flow control valve assembly. Lower plate should be the hydraulic pump.

Since you've got an I&T manual, follow the procedure in the manual for removing the flow control valve assembly (par. 358) and you should be able to pull the tube out and replace the O-rings on both ends. It requires pulling the top cover (par. 347), but not a tractor split

Thanks, Sean; figured that was what is was going to take, but wanted to poll the more experienced first. Once I get this taken care of plus replacing the gaskets and o-rings in the leaking CAV injection pump I'll be able to breathe a bit easier, LOL.

4000s are outstanding old tractors.
Worth getting on the learning curve and doing some tweaking on.

Mine is a good one; I bought it from the son of the original owner, and it has worked the same piece of property since it was bought brand new...used for hay and light family farming, so it's not beat up much at all.
