MF 165 hydraulics not functioning

Good evening. I am looking for some assistance. After reading through several posts on here, I am still stumped on a resolution.

My folks tractor was severely leaking oil between the rear axle and the transmission. While attempting to fix that, we split the tractor (and inadvertently broke the dash pot in the process).

We got a replacement part and have re-assembled the tractor, making sure we had everything lined up and torqued down.

After putting in new oil, we were ready to load up the tractor and take it back to the folks, but we are unable to get the three point arms to raise (not sure about lowering). Also not sure if the rear hydraulics are working.

We have replaced the oil, confirmed the level, checked the linkage for the quadrant. Confirmed that linkage is moving when the response control cover is removed.

At this point, I am unsure what else to try/do to get the hydraulics working again.

I have several pictures of how everything came apart and was put back together if that is helpful.

Appreciate any and all assistance!
 
Is the tube that goes from the pump up to the top cover in place on both ends? Sometimes you thunk it is but it is not in on the bottom.
 

We verified that the tube was in the port. We also verified (before this last attempt) that it had a pretty good seal, at least as far as we could tell.

I want to thank you all for your help on this. We did find that the stand pipe was off of the lower port hole. Once that was pulled down, the three point started working.

Again. So appreciative of all your help on this. We thought we verified everything.
 
Ill back.
Now that the three point is functioning and we finally got the tractor back home, we went to hook the loader back up on it and we cant get those hydraulics to work.
We have the inner quadrant lever set to constant pumping and the outer lever to up.
The right side aux pump lever is locked forward and the hoses to the loader are hooked up (Farmhand loader with remote controls connected to loader assembly).
As far as I can tell everything is set like it is supposed to be (even checked operator manual).
Anyone have ideas on what I am doing wrong?
