Case 530 Bendix steering function question.

Hi all, I have a lot to browse here when time allows but I have a question that may not be answered elsewhere. I have a 530SL with the bendix steering power assist cylinder with the combination ball stud/tie rod end on the working end. As I am forced to be creative and frugal (purists may want to stop reading here lol) I am thinking about making something "new" to make mine functional again, it appears to be in very poor shape from many years of neglect. I have found a cylinder that will move similarly but the housing will stay in pace vs the current design of the housing moving. I am also looking at the image from the post of: "1961 Case 530CK Bendix Power Steering Not Working?" and my question revolves around the valve housing. I am looking at it in the shop and it appears it just provides constant pressure to the two working side ports? The through bolt just holds the two end pieces together enough to get it installed easier? There appears to be no valve movement created by the steering? Mine is badly (c)rusted, and my idea is to put the valve on a bracket that allows for much less hose and movement needs, and a hopefully far simpler to replace tie rod system. Thank you for letting me pick your collective grey matter B

Hello Bear welcome to YT! I am linking the post you are
referring to. Too late to go into any details tonight. You
probably would get better results if you would post this
on the Case forum. See ..jump to or hop to.. drop down
box to find that forum if you cannot figure out how to
find it.
Old YT Post being referred to

I am not understanding if you are claiming the design
has no valve action or if you just observed that on your
machine. Look at the breakdown diagram in the linked
post, in the lower part the Ball Stud to the left of part 1
is what connects to the steering linkage that the
steering wheel and gear box move. Now look at the
right of the upper part of the diagram. There you see
the Valve Spool Bolt, that bolt screws into the Spool
shown a bit to the left. That Valve Spool Bolt senses
the movement or slack of the Ball Stud then moves the
spool valve to direct oil pressure to the correct side of
the hydraulic cylinder section to assist the steering.
You are proposing to mount that stationary and
somehow direct fluid to the cylinder you have
purchased? This will not work. Also by ..working ports..
do you mean where the hoses connect to it? If so one
is pressure and the other is return.

If you cannot fix your steering cylinder for the 530 ag. I do have a good one for sale m y e mail is [email protected]

Thank you for the reply, it was more informative than maybe expected. The spool valve assly that I have here is in such a condition that I feel it is likely non-restorable. I have not yet come across a "rebuild kit" for the spool valve to evaluate more on that yet, nor a ball stud rebuild, and the housing end has no threads left - hence my aspiring to change things up a bit and find current parts so that I could change the design and maybe make it a tad less wear prone. Might be a pipe dream either way but I will put a little more time in it.
On "my" spool valve the only part that seems mobile is the through (valve spool) bolt, the rest of the internals seems to be solidly adhered together with the outer sleeve and spool bolt removed, not to mention the sleeve components are pretty beat too.
I may find some vision in it depending what I find from here, the switching valve is obviously an aspect that needs more pondering before I totally call it "dead".
