I have a 2009 Kubuta M6040 4WD. It is starting to leak oil around the hub right behind where the tire studs are in.
How do I get that apart. I took the whole gear case apart but couldn't see how to get it apart further. Do I need to use a gear puller or something?

I am guessing the oil seal #80 is what is leaking

Remove shims 030, remove bearing 020, remove bevel gear, remove 2 050 keepers, that will allow you to push 010 out of the bearing, seal and case.
Everything should be tolerance fit, only light force is required to remove any part.
