BH75 Question

[BigBoyToys]

I have a BH75 on a 2006 B3030 which I picked up recently. It only has 257 hours on it and I noticed the other day when I was greasing it that there was a little bit of hydraulic oil on the lower section on the Dipper Control Valve. Looks like it's the relief valve that extends down.

Valve #3 in the picture below...



I want to check the hydraulic lines to make sure they are tight. The WSM has a table for torque requirements on the lines but I wasn't sure what type of fitting are on them. This is my first tractor so I'm in the learning process.

These are the lines I'm referring to...



Here's the torque table...What type of fittings are on these lines?

I've had a few issues with my valve control unit in the past, including leakage. But never from the hose fitting. Not sure exactly what the fitting is called but it is a seated type that once you hit bottom, torque a tad more. No need to kill it. I suggest you clean the contaminated area as best you can and monitor so as to detect the source of the leak. It can originate from the uppermost part of the valve unit. C.
