Re: SD> Rack and pinion valving

[Larry Carlson]

   I don't really understand all I know about this, but Factory Five Racing 
says you can leave the holes open to the environment after draining all the 
oil out of the Mustang power steering rack.  I hear that race-track 
officials will not allow them to run that way, though.

   There is a rotary control valve right where the steering shaft attaches 
that feeds pressurized fluid to one side or the other of the rack piston. 
If you drain all the fluid out of the rack assembly (you might want to leave 
a little in there for lubrication), you should be able to plug all the holes 
at the rotary control valve, cut the two oil lines from the rack tube, and 
clamp a hose between them so air can pass from one side of the cylinder to 
the other.  That would make it a closed system, allowing no dirt inside.

   Whaddya think?  Would that work?

   If your rack needs replacing, why don't you just get a manual rack? 
Oh... it steers too slow for you, huh?

   Good luck.

Subject: SD> Rack and pinion valving


Can anyone tell me where the valves are for the high pressure system of 
our rack and pinions, and how to get to them? The honda guys have kind of 
a cover plate they can remove to pull out the valving in their racks, then 
they loop the feed and return lines together and add a breather canister, 
and claim it makes it almost as easy to turn as a manual rack and pinion, 
but you still keep lock to lock ratio. Since mine needs to be replaced 
anyways, I figured I'd give it a try, but we have no cover plate, so I'm 
wondering if anyone has an idea of how I can get to the valves, or if I 
can pull one of the 2 hard lines and throw a breather on it to relieve the 
pressure. Thanks in advance.
