I have a Massey Ferguson 165 and when I bought it they said it did not have power steering. I bought the tractor and proceeded to fix the leaks and such. I decided this winter to fix the front end sheet metal upon removing it I found it did have power steering. I have made a lot of adjustments to see if I can get it to work. When I looked it up in the book it was completely different than the book has pictured. It also has a Parker Hannifin pump on it. The steering does work to some extent but not like my 150 I posted a pic and would like more info on this set up and numbers for a rebuild kit for the cylinder and valve. Any help would be greatly appreciated. Thanks in advance.
