Ok, I tackled the procedure outlined above today. Winch not mounted in truck yet, but all "clocking" and waterproofing are complete.
It seems that small updates are made to these from time to time. My planetary side had the paper gaskets, my motor side had thin rubber ones that were already a bit stiff. All of my little bolts inside are black, and overall my winch is black, and not the gray I've seen before.
For the motor side, If you still have the long applicator on your gasket material (I used Permatex Ultra black), you only need to slide the motor case out about an inch. this keeps 50% of the brushes in contact with the arbor and no need to mess with them and allows one to put down a pretty good bead of sealant.
A note about the cable and the springs for the cable tension arm. I used a forest of zip ties thinking this would prevent un-spooling and other nastiness. It did not. I get the joy of installing a winch with a completely unspooled cable.
I watched most of the above youtube video, and mine was pretty well packed with a dark grease as well. I left mine alone, and simply cleaned and supplemented as needed.
