67-ish Ford 3000 *bleed hydraulics after fluid change??

[jimmyl]

So down right now!
Removed hyd cover because lift lever seized. Got the linkage/shaft freed up finally. Bought a kit and replaced all O-rings in cover and cylinder. Flush and fill rear end/hydraulic area.
Got hydraulics cover back on with help from son. Fired up tractor and lift arms do not move!!
Do I have to bleed the system? (at pump I believe), or as I fear is it likely to be something eternal? And what would be my prudent troubleshooting steps from here?
Btw, I can't remove inspection cover on left side of tractor because mine has a hand brake, and it is never coming off!!
Thank yall for any replies....

Check at rear of hidraulic pump and see if thick pipe just slide into the pump ? Clean around that pipe and seal with silicon overnight and try again in the morning .

I did bleed the system from small Allen opening on pump with tubing and allowed to run into fill hole. It is definitely moving fluid....
