Fixing a Leaky RF-45 Mill Head - Grizzly G0519
#22
Here's the top of my head with the gear train still in place.
   
I removed the shaft that the motor drives using a socket of the same size as the shaft. A light tap with a rubber mallet was all it took
   
I removed each of the gear shaft end bearings with this gear puller/separator. There are 5 of these smaller bearings.
   
Two of the gear shafts have a plastic plug cover the end of the shaft. I used Ed's idea of drilling a small hole and inserting a screw to use as a pull to remove these plugs (not shown). After the plugs are out you need to remove the circlips on each of the holes (again not shown). The circlips are laying under the head in this photo.
I used Ed's technique of suspending the head lid over two pieces of wood and then using a socket of the correct size to tap out the gear shafts with bearings. The shafts came out with light taps of a rubber mallet.
