1942 John Deere BO - Part Source?

[Cjet]

My local dealer said this is NLA. I'm looking for a R.H. Differential shaft bearing cover part# B189R. I have rust holes in the one on the tractor. My options are find a replacement, salvage a used one, or removed and weld up my existing one. Does anyone know a source for a cup style expansion plug?

To remove that cover you would have to split the erar axle from the main case and remove the differential. What if you cleaned the cover of all outer oily residue and put some JB weld or other hard epoxy over the holes? There is no pressure to deal with from the main case and the fix would be covered by the reduction gear cover.

What unstyledB said would be my first try. If that isn't what you want, it looks like a freeze plug that may be sourced from your local auto parts or Napa or get a good measurement and google search it. Should be able to pull it out with a slide hammer!

That looks like an ordinary cup type core plug. You should be able to find one in most any auto parts store.
