Bosch Steering Box

I know there is a lot on this but has anyone found where the screw is to tighten the play on the Bosch steering box. It's not the hex nut on the right as when you loosen that fluid comes out and it will only tighten so far.

Is there anything on top of the steering box that could be a adjusting bolt/nut?

Nothing.

It looks like there is a cap on the top directly opposite where the shaft comes out of the bottom. Maybe under this. I am trying not to break it. I can't seem to find anything from Bosch on this part either.

Bosch steering box is likely to be internally preloaded with shims and torrington bearings like the larger truck types. The hex plug is stamped with 110 indicating it is the 110bar steer limit relief. Looking at the sand around it I would not be surprised if it leaks in the future. What is the issue that sector shaft preloaded needs to be adjusted?
