Steve -
Don't forget the single bearing at the back end adjustment. Tighten
only enough to eliminate any sideplay at the front bearing.

Working on cleaning and refurbishing R-4B s/n 15533B, I removed the
PTO and started to clean and re-lube the bearings. After some 3-in-1
oil and Rem Oil in all the usual places, it was still a little stiff,
so I removed the cover and started backing off the tension
adjustment. I now know that it doesn't take much tension removal to
make the ball bearings start dropping onto and rolling about the
table! It was a bit of a bear getting them all back in, but about 20
minutes later - mission accomplished. It's tuning smoother but I'm
still feeling some roughness when turning it by the shaft. I suspect
the action will be easier with that big knob back on it.
Watch the bearings when adjusting tension!
