Hi Marv
I have the 12-inch version of that lathe and have rebuilt the whole thing. I never had to remove the spindle bearings, but had the rest of the headstock apart. The gears and pulleys are Zamak, not cast iron. They are quite fragile, but should not pose a problem for you. The collar on the left end of the spindle sets the pre-load on the bearings, which are tapered roller bearings (Timkin). Have you adjusted the bearings yet to see if that takes care of the problem? There are PDF versions of the manual from Atlas available online that will tell you the correct adjustment procedure. I don't remember the specifics exactly, but it is not difficult. The idea is to run the lathe long enough to bring the bearings to running temp, then use the adjustment collar to remove all end play, then tighten very slightly past that (I don't remember exactly how much the manual says to tighten). The manual will also describe the procedure for removing and reinstalling the spindle and bearings. It is not difficult to do the spindle, but I have not R&Red the bearings to say how difficult that is. I imagine it is like any other bearings of this type. Hope this helps you.
