Massey Ferguson 283 Farmwithjunk or anyone

[Donovan Caro]

I just purchased a MF 283 1987 UK with a A4.248 engine. My hydraulic or set up with Flow control valve Auxiliary hydraulics or set up with Dual spool valve and rigged pipe assembly Factory fitted. My problem is my hydraulics or not working I drained fluid cleaned filter filed unit with diesel ran unit auxiliary seemed to work great 3 pt. They went up and down but couldn't hold weight my weight witch is 200 pounds. Drained the diesel out filed unit back with hydraulic fluid nothing. I purchased a workshop service manual but there's no trouble shutting info in it. Hoping someone could shade some light for me on this system what to check or any help. There's no pressure no where. I'm really looking forward to using this tractor for my hay fields. Is there a trouble shutting guide for this unit?
Thanks,

My guess? Stuck relief valve. Not real familiar with that series tractor.....

check the screens and filter again.

Relief valve would it let oil up the tube at all. When first cranked oil comes up the tube then stops after a split second.
Thanks
