Well just to provide an update on where I am at. As I started this thread as a rehab and not a restoration my goal is to avoid a big project. I don't want to tear it all apart and repaint it etc. I just want to clean it up, inspect and replace anything that needs to be replaced and use it for a while with the goal of eventually doing a tear down and rebuild and repaint.
So as I am cleaning it up I am noticing a lot of the green paint flaking off, so I decide to scrape off the remainder of the green paint and go back to the original grey paint underneath which appears in good shape. After scraping off the green there are areas that will need to be repainted. Repainting is going to be an issue with the seeping hydraulic oil so I will need to drain and fix those leaks first, well I cant get the exact right colour so I guess the whole thing is getting a coat of paint, and so on until I am here:

I still have a long way of scraping/sanding/filling to go before paint but it is moving along. I think I have addressed all of the leaks that I know of with the exception of one that I could use some advice on.

The outer bearing on the feed shaft is a loose fit in the housing, spinning the shaft the outer race spins. Obviously oil is leaking around this bearing onto the flat belt pully and from there onto everything else. I will replace this bearing but I suspect the housing is the more likely worn part vs the hardened bearing race. Is there a missing oil seal that should be before this bearing? or does anyone have a recommendation for a sealant that could be used between the two surfaces to prevent the oil leaking?
Any suggestions on how to attack this?

A 6204 sealed bearing is the one you want on the end of that shaft. The inner bearing also a 6204 needs to be fully open so oil flows into the gear box. Check that the inner bearing isn’t clogged up with gunk etc. on mine a new bearing is a moderate press fit on the shaft yet slightly tighter then a slip fit in the bore. A light bead of RTV around the external bearing race would probably take care the leak. Also good idea to put a new gasket between that casting and the gear box while you have it out.
