I don't think I mentioned that it's an air/oil spinde.
To explain more of what I mean, I can actually use my hand to lift the spindle up and down inside the cartridge 0.12mm. If I use a length of wood on a block to act as a lever, then put all my weight on it I can see about 0.15mm movement. I'm 70kgs and the lever was about 5:1 so exerting about 350kgs force upwards.
Just now I did the tool release test you mentioned. It shows the spindle dropping down 0.09mm (0.0035"), which is well outside the spec you gave. However, when I then force the spindle up with my wooden lever (as I said above), then reset the dial gauge and hit the tool release the difference is now 0.25mm (nearly 0.10").
I also just found this in the manual with regards to preload adjustment using the tool release method and 1000lbs:
15,000 / 10,000. 0014-.0017 (Can Not be adjusted) Air/Oil
I can see the nut on the top of the spindle, just below the pulley. I wasn't away that there was also one at the nose. How can I hold the spindle while trying to tighten it?
Cheers,
Matt.
