This is how I'll use them in the future, Fill it to the as yet to be determined ML and let it drain in slowly as the bearing warms up, one on each side.

I measured the bearing seats and came up with 1.7706" on both. I can't get an accurate measurement of the bearing ID, I don't have an inside mic or a bore gage big enough. I believe .0005" per inch for an interference fit is what I remember.
By bearing # it's 45mm

Calculations indicate inner ring rib angular velocity is less than 1700 fpm when spindle is running at 2300 rpm. If memory serves me "standard grease" would work OK at these velocities, testing may indicate adjustment of preload to control heat to acceptable levels is needed. An arguement could be made that the headstock as designed & produced by SB had grease lubrication for the bearings included from the start and some where along the way grease was changed to oil. Considering that the headstock has no way to drain oil, shield wiring and switch from oil spray, the bearings come packed with grease along with "grease fittings" for oilers. This train of thought leads me to think a heat issue may have caused SB to change to oil considering the bearing preload. Oil churning in the bearing produces heat build-up in the oil and therefore drain holes need to located as to drain away oil and maintain a minimum level to adequately lubricate the bearing. The bearings, while the spindle is rotating, both spray oil and drain oil away, it seems an oil starved condition could result without additional oil being added at some rate to maintain an adequate film. Greased bearings on the otherhand don't remove heat and small particles as well as oil. Seems to me a person could use grease or oil to lubricate the bearings although machine warranty may be an issue.

Funny, had someone else speculate that they changed from oil to grease when I found grease in my bearings. I respectfully suggest starting a new thread on 8K problems, that's not why I started this thread, it was to help new owners with any definitive information I could give them. At this point the spindle issue is still an ongoing problem and not solved.

Recently went to Grizzly/South Bend website looking to purchase some parts for the SB1001 lathe and found on their list of parts many showed "This part is no longer available". Does anyone know what's going on with the SB1001 lathe? Could it have been discontunied and as parts run out thats the end of it. The lathe is listed in the new catalog, at a sale price of $1965.

edn's post 210 - edn, I'd be interested In what you find when you go about replacing your spindle. You explained you have new Timkens (ISO class p5). I'd be interested to know the part number. Thanks.

According to Papa Grizzly the lathe will be discontinued, according to tech support, not discontinued.
That's one hell of a list of not available parts, makes me think about returning it and get a 10K.
This can't be right because there's the same long list on no longer available parts for the 10K?

Looking for Ser #'s, mfg dates, and where it shipped from and if any grease in bearings or other spindle issues to update my list.

Received the lathe today, honestly it felt a little toy'ish since I'm used the the Bridgeport, all though feels foreign.

I cannot wait to learn how to turn some parts.
