Default Power Steering not working

Hi

Its been a while since I last posted

The power steering on my 69 has stopped working, car has been sitting a year or so.

I rebuilt the control valve a couple of years ago due to it leaking. And it worked fine.

I took out the PS pump over the weekend and checked the valve and it wasn't stuck.

Any ideas on what to check next?

Fluid is at correct level

thanks

I’m not sure, there doesn’t seem to be any movement of the fluid in the pump when you look in the filler cap

well power steering pumps do go bad....sounds like you need a new one.

i suppose you could test it by running the car with the low pressure side of the pump disconnected and see if any thing is returning to the pump. this is the small hose held on by a hose clamp in the back of the pump. if nothing is being retuned then it sounds like the pump gave up the ghost

YEP...it seems that the pump has gone bad....but checking it out may be worth while to confirm it.

And PS belt slippage?

that certainly would contribute but to have no movement of fluid the belt would have to be disonnected

Hi

Checked the return pipe and its got a good flow of fluid.

No belt slippage, I read somewhere before about a ball bearing that get stuck and you need a magnet to free up? But cant find it online again

thanks

Have you disconnected the P/S ram from the chassis fixing point and seen what happens when the wheel is turned? It should of course, push or pull the rod in or out of the cylinder. If not, is the cylinder working? I'm guessing it possible that the seals may dry out if the car has stood for a while? Might be worth putting new seals in the cylinder? Otherwise, I'd suggest another Control Valve re-build.

Why not take the high pressure line off the control valve and re-route it so that it flows into the top of the pump? When you start the engine, you'll know if you have flow or not.
