I'm replacing the spindle motor bearings on my mill. I removed the motor from the machine, removed the pulley and spacer, and removed the lower bell housing from the motor. It looks like the grease over time ran out of the bearing, and there's lots of it in the bell housing. It almost looks like there's more grease in the bell housing than there could have been in the bearing to begin with.
The replacement bearings are sealed and thus pre-lubricated. They're also the bearings speced in the Mitsubishi manual, so they're getting replaced with the factory recommended bearings.
My question is should I clean out all the grease that's at the bottom of the bell housing? Should the new bearing go in clean and dry? Or should there be grease in the bell housing between the bearing and the wavy washer?

I realized there's no good picture showing how much grease is in the bell housing. I'm going to go out and take a picture of that and add it to the album in a few minutes.
