I need to rebuild if possible the Power steering cyl on my 231S, Do you know who may have a kit? is it the same kit as the 241? thank you for your time
 
The 231S shows to use two different cylinders. From the AGCO parts book (WHEN CHOOSING WHAT CYLINDER YOU REQUIRE FOR YOUR UNIT KEEP IN MIND THE DIRECTION OF THE BALLJOINT THREADS ON BARRELL END, UP OR DOWN. THE BARRELL END IS ALWAYS POINTING TOWARDS TRACTOR. IF THE BARRELL END THREADS POINT DOWN, 0011403U91 IS RIGHTHAND AND 0011404U91 IS LEFTHAND. IF BARRELL END THREADS POINT UP 0011403U91 IS LEFTHAND AND 0011404U91 IS RIGHTHAND. THIS CONFIGURATION ALWAYS HOSE PORTS TO POINT REARWARD).

The 241 had hydrostatic steering only, the 231S could have had either power assist, or hydrostatic steering.
 
I replaced installed a kit on my MF 231 power steering cylinder recently. I found one on EBAY. I thought they are a little over priced for a couple O rings, a dust seal, and a shaft seal. I checked ebay they have one for the 231, and 240 they seam to be the same kit. I would think they should fit yours also? Stan

You must have hydrostatic steering, not power steering (or power assist which still uses a drag link from the steering box to the front axle to steer). Hydrostatic steering will only have hoses going from the orbital motor (steering box) to the steering cylinder (no mechanical attachment between the two).
 
I think the cylinder for the 231 is different than the 231S. Am I correct? Also the more I understand from ptfarmer the more I think my 231S is hydroassist. Thank you both for all the response.

If it has tie rods from the steering box to the front of the tractor, the front it is power assist (or hydro-assist). The steering cylinders, and front steering arms are different between the 231, and 231S.
