After I exhaled I am not so high on grease anymore.
While testing the seals on the Nachi bearing, I was surprised to feel and hear any clunking from the bearing even with grease in it. I get a lot of that when spinning the bearings dry, but didn't expect any when greased, but there is still some of that going on even with grease. I assume it is bits of debris getting caught between the balls and race, or the cage getting in a jam.
After a couple hours, what started out as a golden honey-like grease has turned to black goo. I am now thinking the grease may not be as good a lubricant as a continuous flow of oil. So I think I will go back to the oil route.
One thing I do know, before my new bearing goes into my Box, it is going to be run in grease for 3 minutes, cleaned and re-greased, run for 20 minutes, clean and re-grease, then run for 3 hours on the test stand before being oiled and installed.
