Hydraulic Cylinder Problem

[kennyd]

I took the cylinder off and there was no fluid in the cyclinder to drain out. Does that mean the cylinder could be air locked or some other problem. Fluid will squirt from the detached hoses when actuated. I have attached photo if that is helpful.

Have you tried to pull the rod out? If so-how much resistance is there? I am still thinking the nut came off inside.

The rod floats free, I could pull backhoe boom out and the rod would push in. Let the boom drop and rod would pull out. The rod floats free, with the cylinder off the tractor.

I think, I have a high pressure hydrualic gauge. I will see if I can find it and get some fittings to attach it to the value.

It pulls a little hard, but with a little leverage it moves full stroke in and out. I will try opening it up this weekend and see what it looks like. Who knows, I may be able to get it back together.

That will be the only way to know at this point...Take some pictures for us:thumbsup:

One other thing, when the rod in all the way in, about an inch or two of the rod sticks out of the cylinder. Is that normal, or could that indicate the rod is hitting the nut keeping if from pushing all the way in.

Not normal...I bet you could pull that rod all the way out!

I believe (from your picture) that it should go in to the paint line on that cylinder.

I do believe the nut has come off the bottom of the rod that secures the piston. That is why you have no movement on the cyl rod, and the reason the rod moves freely.

Did you say it only had 20 hours on the BH?

Hi, first post here. Have done alot of reading on here and gained some valuble
info.just rebuilt the lift cyl. on my loader and all I can say is what a difference! Now back to this thread I guess it could be a piston nut but maybe just the piston o-ring blown to pieces as it was in my case. Thanks for all the good info.
