Leaking Hydraulic Coupler

[Anonymous-0]

I have a rear hydraulic coupler on my Farmall 350 that leaks a little when the tractor is just setting and not hooked to anything. I have pushed the ball within the coupler assuming there was a piece of dirt by it but no luck in stopping the leak. What else can I do barring replacing the coupler?

Well, if time is not important, you could take it apart and lap the seat with a new ball and then install a different new ball. Some have a snap ring to peel out and some have a screw out that of course you will have to make something to screw it out. I did that about 40 years ago just out of cussed ness but it isn't practical.
