Is this the hub that bolts directly to the front wheel..?? If so, AGCO calls it a Shaft-Planet Drive. Also there were 4 different ones for them, broken at certain serial numbers, all with different part numbers.
Apparently a weak link, as I found several threads for guys looking for the same thing. In fact, found one thread here on TBN I replied to. Suggested they contact these fellows. They are always picking up used White, Minnie's, and Oliver tractors to salvage.
