Loader leakdown

[smilingreen]

Hey guys...
I have a #70 loader on my 790 and was wondering if you guys have problems with the bucket curl leaking down. I have probably 150 hours of dirt and rock moving on it. When I pick up a full load, within 50 feet or so, I have to curl it again. It doesn't make any difference if the engine is running or not. What do you guys think? "O" rings in the cylinders or the DSV manifold. Anybody have this problem??

I have a #75 on a 1050. I had problems with the lift circuit leaking down. My problem turned out to be in the valve body. Rain had gotten into it and ruined all the small parts in there. I replaced everything replaceable, alas, not everything I needed was available. It's still not perfect but its functional. The whole valvebody is megabux so I hope this isn't your problem.

A simple test will let you know if the problem is in Cylinder or SCV valve......

Roll back and unhook scv lines for buckett curl.....test if it does not move your problem is in the SCV....
