Got the dead bearing out of mine! Whew. When installing, it seems like you installed the lower bearing into the quill first. Then did you install the spindle, then top bearing.. Or did you install both bearings THEN the spindle? Trying to figure out the order at which to do it.
Yeah....that's why stuff like Bridgeports use them......AC bearings are plenty strong for the loads on a R-8 spindle....But...the Bridgeports I've worked on were $250+ each for the AC bearings/spacer kit...
@diyengineer the lower slid in and out easy on mine, the upper needed pressed into the quill. its easier to press without the spindle in the way. the spindle should be able to slide into the bearing IDs, emery the spindle if needed.
I've been watching your videos for awhile now. Love them. You seem real out of breath this time? Hope all is well with you?
Now...do the same video with no hands at all!!!
Nice job, thank you for the info, i am going to change mine.

What was the thickness of your upper and lower spacer? This video is a life saver.
@BuickDoc i made a belt drive and the stock tapered rollers overheated
angular contacts are more suited for spindles

Why did you change the bearings? Are these better in some way?
Where did you source the wrench for the retainers?
don't know where you get your info but the tapered rollers in these are only good for 4000 rpm.
What tool did you use to unscrew the caps?
@diyengineer iirc .150 for the lower and .100 for the upper
@ShawnColorado seen better days, just plugging along.
