JD 3320 and sinking 3pt

[jschmidt220]

Hello, my 3320 has a sinking 3pt when I have an attachment on. It settles about every 2-3 minutes, then lifts back up. It is very annoying. My dealer said sometimes this happens. This is a bunch of bologne, because it started about 300 hrs. Does anyone else have this problem. Also, by morning if I leave an attachment on the 3pt is completely settled to the ground.
Thankyou
Tim Schmidt

Most likely you have a seal on the lift piston that has gone bad.

Do you have a power beyond on it? I had this happen to mine @ 250 hrs. It turned out to be the sintered filter in the PB had shattered and gotten lodged in the rockshaft control valve. I talked with my dealer about it and decided to dissassemble myself. Sure enough a small piece was in the shuttle valve itself. It was a chore to take it all apart but the up and down hitch is not an option for me. Hope this helps.
