Hydraulic plumbing question, MF 40 Industrial, MF52 back

[akwells]

I have yet another question about this 40 Industrial and its 52 backhoe. I have this Summit loader valve https://summit-hydraulics.com/product/monoblock-hydraulic-directional-control-valve-2-spool-21-gpm/ and it has on it both a tank (T) port and a (N) port for power beyond.

My backhoe is plumbed into the T port. Is that correct? I read some things that made me think maybe it was supposed to be connected to the N port with a power beyond adapter. Just want to make sure I have it right. Thanks.

Did the pressure line from the pump go to the loader valve first when the old valve was on it? What model loader do you have 32, or 34?

I think it is a 34. When I got it, it had the same style of loader valve on it as the one I installed. That one had been damaged, so I bought basically the same exact one and installed it exactly the same way. I don't know how long the previous owner had that valve on it, or whether the backhoe itself worked very well or not. I got it with so many leaks I haven't really had a chance to work it out. Really, I was looking at it to bypass the backhoe altogether while I find some replacement parts, that's when I noticed how the backhoe was plumbed into the tank line. I just wanted to see if that was correct or not.
