My lift cylinders started leaking a while back so I purchased the seal and prong kits. I’ve never rebuilt one before but with a little bit of you tube help it was a piece of cake . As usual the first one took me 2 hrs and the second took about 45 minutes! I took my time and very meticulously cleaned everything before reassembly. I buttoned it all back up and added fluid that was lost . I figured that I would need to purge the air out but I went through the functions slowly and it doesn’t work ! The lift works but it won’t hold pressure down. Tilt up on the bucket works and tilt down does also but I have to hit a sweet spot for down to work- if I go all of the way to the right it will roll the bucket back up. There isn’t any pressure to keep the bucket tilted down. Air in the system maybe? I assembled everything exactly like it was disassembled. Help please

You shouldnt have gotten much air in the tilt cylinder but its possible your valve is bleeding off a little. I work on hydraulic stuff all the time. And this sounds like a classic case of air in the system just from what your telling me. Go put some dirt in the bucket or put a strain on it and cycle it bunch. Shouldnt be any need to crack a line.

The lift cylinders are working as they should and they are the ones I rebuilt- at first they gave me some problems but they are working correctly now! I’ll load the bucket up tomorrow snd go from there!Last edited by Bucknaked; 04-19-2022, 04:15 PM.
