The bearings need to be filled with a

1/3rd fill.
Fill them completely..and they will run very warm/hot
Right, but how the HECK do you determine how much is 1/3rd?
I guess the bearing manufacturer can calculate the exact volume of the
bearing that isn't filled with steel, but I think this could be hard to
do correctly in the field. Hmm, I suppose you could weight the bearing
and then calculate the volume of the OD - ID and that would get you
pretty close.

Nah..fill em full with a bearing grease press, then soak em in solvent,
collect the grease, burn out the solvent with heat, and measure the
grease volume. Then divide by 3 and voila!

Or make an educated guess like I do when packing bearings on machine
tools.
Say!..you could use a grease gun and a needle and fill in between every
third ball! That would do it!
