Planetary drive bearing falilure…. skid steer auger attachment

I had a customer bring over a skid steer mounted auger drive. The unit has no data plate. I have some casting numbers. Here in North-Carolina we have many companies building attachments and the name plates consist of decals.When we build something it leaves with a stamped data plate. You can never have too much info IMO. Do you guys have any idea where I can look for the bearing/seal kit that carries the final drive shaft? It is 2.5" OD drive shaft. This drive may ring a bell to someone, it certainly mean nothing to me. The owners guys never greased anything. The drive looks Chinese to me. I could be mistaken. Nothing like a treasure hunt Thanks, Tom
