Dear all hi,
allow me to present you with my problem and ask for the forum's assistance. I am sure the problem I am facing is, most probably, trivial, but bear with me and provide your feedback if possible.
A couple of weeks ago I noticed an enormous axial play at my FP2's (500 mm X version), around 0.2 mm. I can't tell if this was here since I got the machine (1.5 years ago), or whether I induced it when I opened the spindle for the Kluber treatment, or whether it showed up at some point. I hadn't used the horizontal spindle much, and only for boring/drilling, that's why I hadn't noticed the play before.
I checked my manual and I was happy to find that axial play is adjusted via a threaded ring, no need to grind spacers etc (there was a relevant mention in a similar thread here, but I can't relate to that I think). My problem is that I can't seem to be able to ajust it, no matter what I do. Here is a magnified picture of my manual:

To my understanding, we have a spacer C held captive on the spindle, sandwiched between the spindle shoulder (at one side) and spacer F, inner race of the top roller bearing and the nut 9 (at the other side of the spacer-collar C). So, since collar C is fixed on the spindle, we have quill shoulder A and thrust bearing B that hold the spindle from exiting the quill, taking axial play in the outwards direction. And then there is the set consisting of thurst bearing D, roller bearing outer race E and threaded ring 6 that push the collar towards the spindle nose and takes up all axial play.
My problem is that, no matter how tight I get the threaded ring 6, I can't get the axial play to get any smaller. Resting the spindle on it's nose I can lift the quill up and it does rise up. So, it's like the threaded ring and the parts it is pushing cannot reach the collar C to push it towards the spindle nose. But I can't see anything interfering there to cause that. Has anyone faced something similar or has any idea what might be the problem here?
Here is also a scan of the full page of the manual:

Last, I would like to ask whether my understanding is correct: in order to set the thurst bearing properly, spindle nose should have a bit of a clearance from the quill, right? Something like this:

Thanks in advance for any assistance guys. I know it's no rocket science, but I am at a mental block here currently.
