Hydraulic top link issues

[Kodiak45]

Take a look at the attached video. My hydraulic top link is floating. Shouldn't this cylinder stay fixed, as that is the primary purpose of it...

You are right - it shouldn't do that. If you just installed it did you cycle it several times full extend to full retract with weight or opposing force on it in both directions to get all the air out. Air can be compressed and can cause that.

Disconnect the hoses from the cylinder and see what it does.

Second this post. The very distant second is a problem with the valve....unlikely though based on the way it springs back. It's acting like it's compressing air and springing back.

It must be air. . I did cycle it numerous times, but there still must be some air in there. It started raining on me, so I'll have to play with it tomorrow. I didn't think that disconnecting and reconnecting the hoses would introduce air. To be updated tomorrow.

Typically the hoses connect to the machine with QDs which shouldn't allow any air.

Curious to see what the fix is. Don't have a clue. Sorry.

The way the rod sort of "springs" out when the implement pressure is off sure makes me think it is air.

Hose connections on the side leave air in the top that can be harder to get out. I would remove the cylinder, turn it with connections up, and work it back and forth 10-20 times. Then re-install and test it again.

Bruce, I agree. Curious to how the air is getting there?
