Working on my 4000SU. PTO clutch is in the bottom of the sump. There is a rectangular screen beneath it and a small round screen on the opposite side coming from the pump. I don't see any way of removing the screens to clean them. Is this one of the 4000's that would have to be split to get it all out?

Be careful with the rectangular screen, their not available anymore.
Had one that was collapsed in one of mine, ended up converting it to a 4600 style external filter.

Not really a bad design for back in the day, very few lower hp tractors of any brand had suction screens or hyd filters that where easily serviceable back then, hyd remotes where seldom used on smaller tractors and if properly serviced the system gave very little problems. Ford did change to external filter in 75 with the -600 series models.
My 72 4000SU has never had the suction screen removed but has has regular hyd oil changes.
My 69 4000 hadn't been properly serviced before I got it allowing water and sludge to cause the screen to collapse.
