5288 hydraulic outlets quit working

Can't figure this out. There's absolutely no hydraulic pressure on any of the outlets. Everything else is fine. I can drive and steer the tractor fine. Hydraulic oil level is good. It quit without warning. Anyone have this happen to them?

Others will chime in, I think it is the primary hydraulic pump. either the drive to it, or the pressure regulator is stuck open. Jim

Does the 3 pt lift with a load. If so then probably the pump is working and there are other issues. If 3 pt will not lift a load then that leaves all options open to check.
When was filter last changed?

This may sound odd, but I've had this tractor for 15+ years and I've never used the 3pt. I don't think the filters have many hours on them, but I will check my records. I only put about 20 hrs a year on it. Is there a way to check the 3pt without putting a load on it?

There seems to be a chatter when the hydraulic lever is moved, so pump could be a problem? Is there a way to check that?
