Small Hydro Leak

[fenneran]

I have a YMG1800D, which must be pretty rare since I have't seen anyone else with one, that has a small leak in one of the hydrolic lines. It only seems to drip a little, and only when there is a lot or pressure on it. For instance, when the three-point arms are lifted to the top.
This is a shot showing the line that has the leak:

This is a closeup of the actual joint that's leaking. (sorry for the dirt, I haven't cleaned ut up yet /forums/images/graemlins/frown.gif )

So, now for the questions:

1. Is this fairly simple to fix?
2. Do I need to worry about breaking that joint (for instance, does getting air in the line cause a problem?)
3. If so, what precautions do I need to make?
4. Where do I put more hydrolic fluid to replace what will leak out while I'm fixing it?

Thanks in advance.

Copper washers?? Not model spacific - but similar problem. Used very fine (400/600) abrasive lapped on a hard, flat surface. gently removed imperfections and cleaned all (3)machined mating surfaces too. Simple, really. Stop the leak under heavy load and no bleeding was necessary.

I am not sure of your model. Good luck, Mark
