Back at it again Mf175 power steering

The power steering is still not working right acts like the valve is not actuating the cylinder. I have adjusted the linkage to it and still does not seem to help it. I have also tightened up all the lin

kages that I can tighten up. I do notice that the cylinder has a little bit of play on the right end of it. I have added a video of me moving it back-and-forth engine not running.

There is an adjustment that is just out of view in your video. That horizontal arm with the grease fitting is on top of another horizontal arm. There is a tab on the underside of the top arm that sits in a slot in the lower arm. There is a set screw that adjusts the amount of movement between those 2 arms. You need to back that screw out so the upper arm has enough "lead" to actuate the valve. Then adjust the threaded rod connected to the valve spool to get equal assist in both directions.

There needs to be some mechanical play as Bob mentioned to acuate the spool valve, ALSO MAKE SURE the valve link ends and pins are NOT LOOSE, as an OLD MF mechanic the dealer I worked for always kept the link ends and pins in stock, ANY LOST motion that keeps that spool valve from moving will cause a lot of trouble getting the steering cylinder to work right.

Perhaps this will help.
