JD 3038e Loader won't hold curl

[SPYDERLK]

Its probably the loader control valve. If you pop the QCs for the curl circuit off the valve does it still happen?

Pistons might need to be repacked or replaced, have you done any unusually rigorous work with it lately?

It wasn't the cylinders, I had them rebuilt but they said they didn't see any obvious problems. I put them back on and there isn't much difference. It'm thinking it must be in the loader control valve. Does it have any kind of adjustments?

It doesn't have QC but I could unscrew, but wouldn't the hydraulic oil just drain from the cylinders?

Yes it would. With quick connects, it would tell you if the problem were in the cylinder or in the valve.

Yeah 2. But youve already determined that it isnt the cyls - so no point. If its not drippin on the floor somewhere it is the curl spool in the valve. It will have to be disassembled to fix. JD ought to have a clue about the valve they use / whether fix is feasible.

OK. Thanks for the responses. Now I have a better idea of what to do next.
