Mystery fitting on Case IH 7140 combine

[ihserviceman]

I'm working on a Case IH 7140 combine and discovered a leaking fitting, but there's no clear diagram to reference. It seems to be holding either a plate or a hose. If anyone can help identify it, I'd really appreciate it!

Case IH 7140 has a lot of hydraulic lines and fittings and a leak can be difficult to trace. The fitting you're seeing could be part of the steering or brake lines or a simple oil return line fitting for a cylinder.

Unfortunately, these are not clearly labeled in diagrams and can be specific to a certain feature or attachment. Clean the area thoroughly first, then start the machine, and watch closely to see what fluid is leaking and from exactly where.
