studequest Posted June 27, 2017 Report Share Posted June 27, 2017 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? Link to comment Share on other sites More sharing options...
Rob Dudley Posted June 27, 2017 Report Share Posted June 27, 2017 Be sure the control valve is properly adjusted. Rob Link to comment Share on other sites More sharing options...
studequest Posted June 27, 2017 Author Report Share Posted June 27, 2017 Rob we believe it is but how do you adjust it we can do that before replacing it Link to comment Share on other sites More sharing options...
studegary Posted June 28, 2017 Report Share Posted June 28, 2017 (edited) 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. Edited June 28, 2017 by studegary Link to comment Share on other sites More sharing options...
studequest Posted June 28, 2017 Author Report Share Posted June 28, 2017 FRONT END JUST ALLIGNED// ALL NEW TIE ROD ENDS, BUSHINGS ETC 16:1 ASPECT RATIO 225X75X15 TIRES Link to comment Share on other sites More sharing options...
avantifred Posted June 29, 2017 Report Share Posted June 29, 2017 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 ! Link to comment Share on other sites More sharing options...

He is probably referring to the steering ratio. Edited June 30, 2017 by studegary Link to comment Share on other sites More sharing options...

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 Posted June 30, 2017 Author Report Share Posted June 30, 2017 There is definite leakage I have a rebuilt on order// would you just replace it!! Link to comment Share on other sites More sharing options...
64studeavanti Posted June 30, 2017 Report Share Posted June 30, 2017 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 Posted June 30, 2017 Author Report Share Posted June 30, 2017 effect on steering and use of power pump is?????????????? Link to comment Share on other sites More sharing options...
64studeavanti Posted June 30, 2017 Report Share Posted June 30, 2017 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?

studequest Posted June 30, 2017 Author Report Share Posted June 30, 2017 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 Link to comment Share on other sites More sharing options...
Rob Dudley Posted July 1, 2017 Report Share Posted July 1, 2017 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.

silverstude Posted July 2, 2017 Report Share Posted July 2, 2017 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...

SBCA96 Posted September 5, 2017 Report Share Posted September 5, 2017 Here are some tech articles I wrote that might be of help, they are also reprinted on Bob Johnstone's website. http://forum.studebakerdriversclub.com/showthread.php?5272-Studebaker-Power-Steering-Control-Valve-how-to http://forum.studebakerdriversclub.com/showthread.php?3166-Studebaker-Power-Steering-Pump-Rebuild-how-to http://forum.studebakerdriversclub.com/showthread.php?4534-Studebaker-Power-Steering-Hoses-Replace-how-to Johnstones website : http://www.studebaker-info.org/rjtechoct2014p1.html Tom Link to comment Share on other sites More sharing options...
Albertduble85 Posted November 11, 2017 Report Share Posted November 11, 2017 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? Link to comment Share on other sites More sharing options...
Rob Dudley Posted November 11, 2017 Report Share Posted November 11, 2017 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 Link to comment Share on other sites More sharing options...
studequest Posted November 11, 2017 Author Report Share Posted November 11, 2017 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 Link to comment Share on other sites More sharing options...
