"POWER STEERING" 63 avanti

[studequest]

Friends:

I have had to muscle my car with "power steering" ever since I purchased it 9 years ago.  On the road its fine  Turning a corner its "OK" you feel a delay before you get a surge.  not great- Back up parallel park "fuggedaboutid".

i HAVE REBUILT THE RAM. I HAVE NEW HOSES.   i HAVE ALL NEW FRONT END PARTS.  My  PS cannister does leak and it will be attended to.  I have purchased a rebuilt pump from Meyers.  He tells me the output of the pump is 800-1000 PSI.  I am buying a gauge and getting an adapter fitting to check my existing pump pressure  before switching it out and I am hoping to drive my friend's 64 Avanti to get a feel of another car.  Am I missing anything.; anybody with suggestions.  What do others do?

Be sure the control valve is properly adjusted.

[studequest]

Rob we believe it is but how do you adjust it

we can do that before replacing it

[studegary]

You don't state things like tire size and aspect ratio that can affect steering as well as front end alignment.

Raise the car up with the wheels hanging and see how it steers then.

FRONT END JUST ALLIGNED// ALL NEW TIE ROD ENDS, BUSHINGS ETC

16:1 ASPECT RATIO

225X75X15 TIRES

[avantifred]

Wow they are really wide tires...I run 215 X70X15  & they are noticeably wide but yours are even wider. I sure hope you're not running on Stude wheels?!

You would definitely need a 6" or 6 1/4" wheel for that width tire !

.  I do not know what he is referring to when he states; "16:1 aspect ratio".  He is probably referring to the steering ratio.

yes steering ratio

non power cars 22 to 1

not seeing any mods or suggestions on the steering

if my pump failed or was wearing out what would i experience?

To tell you the truth, I've seen those Eaton pumps leak,....usually at the input shaft seal, or at the two gaskets that seal the reservoir to the pump body,....but I've NEVER seen one of those pumps lose output pressure....I guess it could happen, but that would be a real rarity!

[studequest]

There is definite leakage

I have a rebuilt on order// would you just replace it!!

[64studeavanti]

Actually, the first number is the nominal width of the tire in mm. So, a 225 will be about 1/2 inch wider than 215. The 75, 70, ... is the profile of the sidewall which determines tire height. I believe it is nominally expressed as a percentage of tread width.

[studequest]

effect on steering and use of power pump is??????????????

[64studeavanti]

I was just responding to the post that the 225r75 is narrower than 215r70. While tire width does affect steering effort, I don't think that is your problem. Without having the car to look at, my best guess is that you have something binding. Is everything greased correctly? The king pins can be a bear to get the grease in the thrust bearings. Are the tierod bolts pointing away from the oilpan? Is the steering box filled with lube and properly adjusted?

Drove my friends 60 T bird convertible with Eaton Pump

Wow, the steering (same set up as Avanti) is feather light

We will install the rebuilt pump and go through the system

[Rob Dudley]

The valve needs to be put together with some movement. This allows the spool to send fluid one way or the other.The nut under the cap on the end of the spool bolt should be tightened just enough to cinch it up then backed off  one flat.

The BEST thing you can do to ANY stude or Avanti II to upgrade the steering is to swap out the center pin housing with bushings for a Housing that uses needle bearings.  You wouldn't believe you even needed Power Steering.

and this can even be made better by incorporating one of Ray Fichthorns adaption to use a 3rd bearing...

Here are some tech articles I wrote that might be of help, they are also reprinted on Bob Johnstone's website.

Changing ratio of rear end to lower engine speed at 65 mph. IS says I need a 3.03 ratio 

but not to sure. For Avanti 63R-3444 on frame, 63RQ-2553 on body?

 

[Rob Dudley]

I'm not sure exactly what your question is but you should start a new thread and add more information. What is the ratio now, what transmission do you have and what are you trying to achieve. 

Rob

[studequest]

Ok, we seem to have gotten off track. I bought a pump from Meyers and sent mine for exchange

Turns out my original pump all these years was assembled incorrectly. I also had leakage from my reservoir due to a Ford type top in place that had the spout for filling.  Went to standard lid with wing nut and proper threaded stud.  Steering is much improved

Thanks everyone
