A little late getting back to this. Thanks for all the advice. I just used a rag to clean up and tightened the fitting. No leaks since. I wasn’t sure how tight and there didn’t seem to be a specification so I just did it by feel. Maybe it was half a turn or so.
I noticed a few drops of hydraulic fluid and then saw this messy connection to the loader tilt piston. I'm not very experienced with hydraulics. Is a little leakage normal, something I can fix, or a major problem?
