how to bleed a power steering gearbox?

Question

Last year my power steering gearbox was leaking from the shaft seal on the bottom. So, I removed the gearbox and put in a new seal and reinstalled. Now, I have no power steering.
Although, I don't have a pressure tester for the pump, it seems to be pumping great. I opened the pressure hose and it is pouring out. And if I disconnect the return hose it pours out great. So, I believe the pump is good.
I jacked up the car, started the engine and turned the wheel lock to lock 50x or more with and with out the engine running. The wheel will turn by itself to the right when the engine is running and jacked up. But, it's still hard to turn to the right with the wheels on the ground even though it is easier to.
I don't know what to do now. There is no bleeder valve anywhere. The car is a 59 Plymouth Fury. Anyone with experience or knowledge of this?
Thanks

Ok, for one thing this isn't a rebuilt gear box. It was working fine when I took it out to replace the leaking seal.
The tapping with a hammer ideal sound wise to bring up any air in the gear box but, after much beating and tapping, no change.
I have decided to take it back out and send it to a rebuild shop since auto parts store don't carry or sell this part for my early model Plymouth.
Thanks to all who answered.

Answer 1

dont bother trying to bleed the system...You should have immediate activity to the steering box...You might have a little noise as the air makes its way out of the steering box...

But, if you have gone through all these procedures, then you have wasted your time....You obviously have a sticky valve in the steering gear...You need to take it back where you got it and exchange it...

good luck...These damn part stores will hand them to you all day long...

Answer 2

where the pressure hose goes into the steering box is the centering valve it has 2 bolts that hold it to the gearbox here is the procedure:
1 set park brake and block rear wheels then jack up the front of the car [use jack stands]
2 slightly loosen the 2 bolts and start car
3 with a small hammer tap on housing towards front of car if you tap too hard the wheels will turn left all by itself and you will have to tap in the other direction it is centered when the wheels stop turning on their own lock down the 2 bolts and cut car off then restart the steering wheel should not budge in either direction if it does you will have to repeat the above procedure [note some fluid loss is to be expected so put a pan under the steering gear to catch drippings]
final note this procedure is a learned experience it will take time and patience the 1st time but even 20 yrs. from now you will be able to adj the next one quickly. good luck

Answer 3

Normally, power steering doesn't need to be bled. When you are saying "new gearbox", you really mean "rebuilt", and since over 50% or rebuilt parts come dead on arrival, I suggest the gear box is defective.
