White 2-105 Hydraulic issues

I need some advice on what my next step should be.
I resealed both brake pistons on my 75 2-105 White tractor which had leaked out the hydraulic oil. I refilled the hydraulic tank bled the new hyd filter with the brass wing nut till clear oil appeared without the engine running. Then I loosened the out put line on the hydraulic pump allowing oil to leak from the fitting as the engine was idling. But NO pressure buildup. Only a small stream of oil flowing out of the fitting. After maybe 10 minutes there was a slight warmth to the touch of the pump.
Did I bleed it correctly? Possible fried pump?? Hope not!!!
Prior to me beginning repairs the tractor had hydraulic pressure but did run for a short time with little or no hydraulic pressure due to low oil.
Advice and suggestions will be appreciated.
 
Well not sure what happened! I tried for a good 60 min to get that pump primed before taking a break to have a coffee and asking for advice. When I went back out after coffee I cracked open the pressure line from the pump again and this time there was a steady stream of oil flowing out. I retightened the line started the engine and in short order had hydraulic pressure. So I guess there must have been an air lock somewhere in the lines. This evening I drove the tractor around the yard a few times and the pump ran quiet and the steering appeared normal.
I still have lots to do on that tractor so am sure I will be back for advice. It needs a re-sleeve engine job minimum as it is smoking blue smoke when its running. Oil pressure seems 1/2 to 3/4 on the green part of the gauge. Also the over drive clutch isn't working although the direct and under drive seem to be ok. Have to put it on a load to make sure of that though.
Thanks for the offer call J. Schwiebert. My number is

So the hydraulics are working perfectly now as I had on it the cultivator for an hour and the hydraulics lifted, steered and operated A OK. Pump runs quiet so other then changing the couplers to pioneer for ease of hookup no more hydraulic issues. No leaks appeared on the hydraulics either!

The Right brake is still leaking a little despite the new O-Rings. I did notice a bit of pitting and scoring on the piston. I picked up another used piston which appears in better condition although not perfect so will try replacing the old piston with the used one.
