Hi,
I'm having a lot of trouble bleeding the air out of my pas pump on my 1972 f100 390ci truck.
I have read posts on here about bleeding, but I can't find the pas bulletin link.
Can someone point me to it, perhaps that will help me.
Thanks
Johnny

Re: bleeding power steering
It shouldnt be to bad, all ive done in the past is turn the wheel lock to lock a couple times then re-check the fluid level.

Re: bleeding power steering
If you have a drill driver and an appropriately sized allen head, then slap'er in the chuck and prime the pump to circulate the system to purge any trapped air.
Refill to full.
Fire it up and allow to run for about 20 seconds and turn the wheels lock to lock a coupla times.
Recheck fluid level and top off.
Take for a test drive.
Recheck fluid level and top off... Done.

Re: bleeding power steering
Thanks for the advise,
The truck had a conversion fitted in the USA before I imported it, and I has always been noisy. The pump was a recon unit.
Reading on here , a lot of guys have had, poor quality recon pumps.
Will try again bleeding as you surgest, it may be the pump, its the pencil neck filler type.

Re: bleeding power steering
The biggest problem with reconditioned PS pumps usually isn't the pump. It's usually the way it was installed. --like HIO was saying about priming it first. Most people install the pump, fill it with fluid and bust the engine off.
If the pump isn't primed first, there will be air in the system. Air displaces fluid from submerging the pump while it's running. If the air isn't evacuated before the pump can be sufficiently covered in fluid, it will either burn the pump up or, it will cause damage to it, which will make the pump whine the entire time the engine is running.
How I primed the pump in my truck when I installed power steering.

Re: bleeding power steering
I have removed and stripped/inspected the pump, and it all looks ok.
I will attempt bleeding it as you have suggested over the weekend , and hope that works

Re: bleeding power steering
Ok Guys,
I have finally got it sorted out !
It turned out to be drawing in air at the steel case where the high pressure pipe comes out.
I fitted a new cardboard washer, coated in rtv sealant.
It bleed no problems, as suggested, and has been fine since, thanks to all who helped with ideas.
I also made sure I used the correct Ford spec fluid, in the UK the ATF fluid meets the Ford Spec
