7045 Hydraulic Line Leak

Standing at the back of the tractor, there is a leak on the right side of the valves.  It is barely a drip when not in use, but a pretty good drizzle when EITHER remote is actuated.

Been there done that and made a homemade crowfoot wrench.

Wouldn’t an input line be more of a spray? This is a straight down drizzle. I’m getting older but still pee harder than that, so I was thinking return line. I do not know, was just my thinking, also not leaking until in use? Wouldn’t a supply side leak be like a flow demand? Again, just asking.

There are a couple fittings I can get a straight wrench on somewhat, and though quite tight I got them a little tighter with no improvement or detriment. The leak seems farther forward and maybe lower?

So, if I take the auxiliary tank off, I come at it from in front of the axle? That’s for the front end of the lines and take the back off at the valves?

I use an 1 1/4 crowsfoot from the rear and have good luck doing it that way. If the flare is cracked, then you would definitely have to take off the right side fuel tank and bracket.

Thank you. So, how many lines are there? Just 2? I can’t see a third, but seems like it isn’t either of the 2 nuts leaking, seems further toward tractor front. I need to take another look I guess.

So, you can spring it out enough to replace an oring if that’s the problem just from the back?

Thanks a lot!
