This problem has annoyed me for a long time.  When it's cold the the power steering system on my Eagle grinds and whines when making any turn and blows ATF out of the reservoir which gets all over my alternator and makes a mess.  After it warms up it is fine.  Why does it do this and how can I make is stop?  I keep the fluid level between the upper and lower level on the dipstick.

Possible.  I've been buying them from NAPA  filter #1487.    You say the correct number is posted on the Eagle board?

1487 is the right filter.  Not sure what I'm doing wrong, but it sure is noisy when cold.

Ok in the canister you have the filter setting on a big washer and rubber seal washer same thing on the top with the spring on the top ? if that is in place you can remove the top run the engine and check for air bubbles you should have a vent is it clean

Started engine, slowly removed handscrew from top.  When it came out all the way I promptly got a bath of ATF.  Quickly put the screw back in and cleaned up the mess.  Fluid is low which I expected since it was thrown overboard when it spilled during groaning turns while cold. 

I cannot duplicate the groaning here in Texas hot weather.  It only happens when it is  below 55.

The manual shows no picture of the nomenclature of the reservoir.  The parts I have are the handscrew, washer, cap, spring, filter, rubber washer and reservoir can in that order.  Am I missing anything?

My Sheppard system does that when i overfill it while cold and there is air in the system.

I now wait until it is warmed up a bit before I add fluid. Motor oil in my case.

Check the suction line for restrictions they should not blow oil every where with the engine idling send me your address I will send my Ross manual to you
 

I remove the top with the engine running and never had one "knock on wood" blow oil out just a swirling motion of the oil inside the canister

 Run yours for a few minutes shut the engine down remove the top and see if it is milky or has air bubbles

The eagle manual contains a detailed breakdown of the operation of the steering pump system.  Is your manual different than what I have? 

The lines are original as far as I know.  Maybe I should change them out.  That will be a big job replacing those front to back lines.  Yuk Embarrassed

David do you have the Eaton or Vickers pump ? If you have the Vickers I would remove it and check to be sure the fiber coupling is still intact the Eaton is round  pump and is gear driven

I'll check.  We got home last night 2300 total miles.  I will check sometime next week.  Got lots of catching up to do since we have been gone almost a month.

opened up the reservoir and drained the fluid.  Couldn't find anything in the bottom at the suction end of the tank that would restrict flow.  Restricted flow on the suction side is my most obvious problem at this point since the pump is returning more ATF to the reservoir than it is taking out when its temperature is low.  Is there any kind of pressure valve or restriction valve on the suction end of the pump? 

I'll have to take the floor out of the bedroom to get to the pump.  I'll do that sometime later in the week.

David,

The pump cannot return more fluid than it takes out.
It may be pumping air through a supply side leak and returning that.
Good Luck and let us know what you find.
