Well I'm finally down to replacing the last bearing on my SS (1957 Greenie). It has the original single bearing quill (with the original 202KDD5bearing - 5/8" x 35mm x 11mm). The bearing was about 1/32" from being all the way back on the shaft. I pulled the bearing off and can now see that the shaft has a groove that was factory milled at that spot (see pic):
My question: Do I put shims here (in this groove) so the new bearing is tight and flush with the c-clip in the quill front? Or do I just press on the bearing and stop when the bearing is back far enough to put the quill c-clip on? Thanks for all the help and I am embarassed a little that I have been asking so many questions, but I am learing alot and my goal is to complete this maintenance correctly.
I checked two gilmer quills that I have. One had the bearing up against the shoulder. The other was adjacent to the groove. If it were my machine, I would seat the bearing up against the shoulder.
I'm no SS expert yet, but I've been turning and milling parts for over 30 yrs:eek:
That 'groove' is 'relief' for grinding the shaft to size after turning on the lathe.
Grinding wheel corners break down, and this groove allows for that.
It also assures that the bearing inner race will 'shoulder' against the step in the shaft without binding on one side.
I hope I helped some!
Your actual SS question about where the bearing gets pressed to is better left to another who knows that part.

Thanks for the picture. It really helps to answer questions.
No shims on the shaft. Press the bearing on all the way. You may have a shim that goes on the outter race between the bearing and the housing snap ring. The rounded side of the snap ring goes to the outside. The spindle knob goes tight againest the bearing. The groove was cut for several reasons. It is a stress relief for the shaft and prevents any material from stopping the inner race from totally seating on the shaft. I try to always cut this groove on shafts that are using bearings.

Thank you for the quick replies. I am getting closer to start cutting some wood thanks to all the expert advice I am being provided! I am careful how I word these forum thread titles when I ask a question, so that if someone else in the future needed this info, it might be a somewhat easy to locate.

Thanks again for the passing on your knowledge!:)
Careful selection of thread title is important and greatly appreciated; however, this forum is notoriously "off subject". Having a proper title helps get to the information one is seeking but often a lot of unrelated cargo comes along with it.
