I have a 3 year old 1023 with a factory installed power beyond kit but yesterday the female hydraulic adapter fell apart and sprayed oil everywhere.
I tried replacing it with a 1/2 adapter from Tractor Supply only to find out the JD OEM part has a little recess in the back for an o-ring. I can't move the tractor without the fitting and I can't find a parts diagram giving me the part number. The paperwork that came with the tractor only lists the parts that came in the kit.
While I'm at it, I'd like to order the proper male hose-end pater as well - I'm guessing I didn't have right fitting on my log splitter and that's what broke the female power beyond adapter.
