When I reomove my 410 loader, I notice fluid leaks from the fittings as it sits there. It does not leak alot, maybe a couple of pints over the course of a week. Has this happend to anyone else?

The fittings on my 410 loader also leak slightly upon disconnecting. But not more than what I would consider normal for any hydraulic implement. I think its normalto have a slight drip, immediately after disconnecting the lines, due to any residualoil in the valve itself. The two problems I've had on other implements, is either dirt in the valve or the valve can tend to stick when new. You may want to check for dirt or cycle the valves, by connecting and disconnecting them a few times in a row, to break em in a little.Hopefully someone can shed a little light on what your problem may be other than this. ....

Have a 410 also. A couple of pints! A quart sounds like a lot to me. Mine will drip a little, which I don't mind. I'd rather they drip oil out then suck dirt in. Definitely check for dirt or a chunk of something which is holding the quick connect open. Also, maybe this is a shot in the dark, but could there be air in the cylinders. The air would expand or contract with temperature (more than oil) and possibly push oil out. But you should know if there is air - operation would be spongy. ....

Bill might be on to something. Expansion & contraction from heat could be allowingair to displace a small amount of oil. Remember, when you use the loader, the oil is warm or hot, causingexpansion. Afterwards the oil cools, causing a contraction effect. I know this is a pronounced phenomemon that occurrs in 55 gal drums. You may also want to take notice of the temperature where you are storing the loader? Most wooden sheds/garages can easily reach 100 degrees or more, especially when its 90 in the shade.Gravity may not be helping the situation either. ....

My Dad has a 440 loader which had a leaking quick disconnect fitting. After much fiddling with it he finally returned it for a new one. The dealer replaced it under warrenty. If no warrenty is left they cost about $10. I don't think it worth the hassle of trying to fix if the dealer will replace it. ....

One more thing, expansion of the oil should not matter. The fittings should seal themselves when they are disconnected, regardless of pressure. Once again, just replace it. ....
