Hopefully this is obvious and you did it already, but just confirm that 2 supplies the FEL and 3 is the return that feeds the 3ph.

And don't forget to switch the PB hose at the FEL control valve so it connects to the PB adapter. Again, I don't want to sound condescending, I'm just trying to dot the Is and cross the Ts.

Yep. No worries, I checked the hoses about 10 times after I hooked everything back up again.

It works as it should now.

Great! Congratulations. Full power on the 3ph?

Full power as far as I can tell...right now the heaviest attachment I have is 300#'s

This has been a helpful thread, thank you. I have a related question regarding my L245DT with 1200 loader. I bought my used L245DT 6 months ago and have been picking away at repairs and other deferred maintenance. For the FEL, the welds between the vertical supports to the frame bracket flanges are partially torn and I plan to take the loader off entirely to repair and weld. It may take 1-3 weeks or me to get to all of the loader repairs done before its ready to put back on and I'd like to use the tractor and 3-point hydraulics in the meantime. Since I don't necessarily have to pull the three lines that go to the FEL in order to take it off, I think the simplest solution is to connect the pump supply and PB lines (with a simple fem-fem adapter) at the valve end before I take the loader off. I can put a simple cap on the end of the return line to the tank to keep it clean in the interim. I suppose I could also get a short male-to-male hyd hose to connect the pump supply to PB/3-pt at the oil pressure block but either way the effect is the same.

Are there any concerns I'm missing regarding connecting the pump supply line directly to the PB/3-pt? My understanding is that (if I didn't have the aluminum block installed on top of the "oil pressure block") the stock cover for the oil pressure block would normally route the pump supply directly to the 3-point in this fashion anyways and would just rely on the single standard pressure relief valve.

I also still need to confirm the connection type and size for the hoses, I'm guessing 7/8" SAE 45deg Flare but TBD...

On the block you can connect A to C however you want to. I will not venture a guess on the size of the hose connections at either end but they look a lot like male NPTF on hose to a female NPTF on the swivel fitting.

See this thread post #1 for the original block and take off block diagrams just so you can see the flow path.

Dont overthink it.
  1. Disconnect the loader power beyond hose at the hydraulic block.
  2. Disconnect the pump supply hose at the loader valve and connect it to the PB return port on the outlet block.
  3. Loop the power beyond hose back to the valve inlet to keep out dirt.
No new hose, fittings or adapters needed. Those are 3/8" NPSM female pipe swivels - do not use thread sealant of any type.
