View Full Version : Single BEaring Quill
How can I tell if it needs replacement. I'd like to have the double bearing one, since it's on sale now. At present I don't have a problem this the original quill?

Hi Beeg
I ahve upgrade to the 2 bearing quill a long time ago and i did not regret it.
It is fdificult to tell whether the bearing is bad but if you remove the quill and hold the quill body and spin the quill by hand and you heasr any noise or feel any roughness it may be time for an upgrade. The 2 bearing quill offers a lot more stabilityy at the back end of the quill and reduces runout at the working end of the shaft. I saw the sale price and thought it was real good because mine cost $66 about eight years ago. In my opinion "Go for it"

Hi beeg,
If you already have the two bearing quill, I wood recommend that you knot buy a replacement. Just replace the bearings when they need it. If you have the single bearing quill, I wood recommend that you buy the upgraded two bearing quill, even if your current quill is working properly. Do knot change it out until you need to, but at today's sale price, how can you go wrong?
You asked, "How can I tell if it needs replacement?" The answer is; If you can knot tell, it probably does knot need replaced. Does the quill wobble? Do you hear "grinding" noises when the quill is rotating? If you turn the quill by hand, can you "feel" roughness in the rotation? Maybe someone else can tell you of other telltale signs.

Since you have a single bearing quill, You can either replace the single bearing with a higher quality bearing (202KDD5), replace it with a new two bearing quill or continue to use yours if you are having no problem. Depends on your wish list.

If you need to know how to tell whether or not your Mark V has a single- or double-bearing quill, see http://www.shopsmithacademy.com/SS_Archives/SS121/SS121_Shopsmith_Reborn_Pt1.htm
With all good wishes,
TOO LATE Nick, I've have it on order now.:D But you had me scared for a bit.:eek: But since mine was built in 1980, it has the single bearing quill....for now.
But you did help, I found this on your list.
"Headstock made after 1984 (Serial No.190000) have a two-bearing quill. These
run smoother and have one-fifth the “run-out” as the older single-bearing quills,
making it much easier to be accurate when drilling."

Beeg: I just replaced my single bearing quill with the two bearing in a recent overhaul of my headstock. My old quill still had a good bearing but I could notice some runout particularly when using the drill press function. The new two bearing quill is super smooth - I kept my old one as a spare (although I dont expect to ever use it). I also paid more since I bought it in July before this recent sale! Steve
I ordered the 2 bearing quill on Moday morning, notified that it was shipped on Tuesday, but that was after the Fedx pickup. So it was picked up form SS on Wednesday. It's on the truck to be delivered today. I might install it or maybe just hold on to it for LATER.
OR I just may start on the kids picnic table, with thanks to Cowboy+
