What is the best way to prime the power steering after a fluid change?

[Reworked LMTV]

Just changed the fluid in the PS system. Probably air in system. Wheel is stiff as a board. What is the best way to address this on this PS system?

 

[Ronmar]

Cycle the steering back and forth to work any bubbles out of the steering gearbox. It is an open center system so the pump is always moving fluid thru the pump reservoir and box but you need to fully cycle the box to get any air out of that part. Check the reservoir as you do this as any displaced air will be replaced by fluid from the reservoir…

Never had to "prime" one. They are gravity fed with the reservoir higher than the pump.

 

[Ronmar]

yea the only place air can collect is in the steering box and then only if the pump was sucking air while the steering was being operated.

Turns out the splines on the pump are too big and do not mesh with the pump splines. Therefore, the shaft on pump does get turned.

I matched up the number on the air compressor when I bought it. Puzzled. Anyone run into this?

 

[wandering neurons]

There may be an adapter that goes between the output of the air pump and the power steering hydraulic pump. A collar of sorts that meshes the splines. Lemme check the parts -24p

Yes, there is an adapter between the tail of the air compressor and the splines on the input of the power steering pump. Could be it’s wrong?
