@nickaix, et al .....
The new bearings are in both motors. Bearing replacement went pretty smooth....but ran into one issue.
Neither of the armature shafts would slide all the way through one of the new bearings. The other armature shaft/bearing fit like a glove.
I measured both armature shafts and they measured 3/16 inch.
Needing something of substance to hold onto, I pressed the troublesome bearing into the motor housing, held my breath and drilled out the problematic bearing on my drill press. The bearing slid right onto the armature slicker then snot! Phew!
Bottom line; both motors hum like new....and for open frame motors run very well.
Here's a quick video of the final results....
Thank you all for your help!
