How to replace Gilson tiller shaft seals\gears

I have a rebadeged Gilson Sears\Western Auto tiller. Here is the full video on how to replace the seals\gears\oil.
I forgot to mention, the "castle nut" is there to be a lock nut with the bearing plate, so tap it so it is tight but don't go nuts and make it too tight.

YW. Being these are built like a tank I'm sure there are many out there where this will come in handy.

How much gear oil does it take?

[@MrFixIt-le7tl]

Sorry, didn't measure it. I had mine tilted back and poured in the oil before closing it up. There is a plug on the front of the gear box. Mine is stuck on. I assume use that as your "full" marker.
