Fixing a Leaky RF-45 Mill Head - Grizzly G0519

[henryarnold]

Here's the head lid with the shafts removed.
   
Here are my gear shafts. The brown on the gears is not rust. It some kind of slimy residue which I have not been able to identify.
   
I removed the rest of the smaller bearings from each of the gear shafts using a Harbor Freight puller.
   
This is the Harbor Freight Gear Puller #93980 which I used.
