3B,
After putting a Mic to the bearings here's what I got.
Inner brg.- ID-1.75, Cage OD- 2.798, Dia.of collar which the seal rides on- 2.32
Inner race- 3.125, thickness-.657
Outer brg.-ID-1.00, cage dia-2.00, thickness-.731
I don't have the race out of the hub to measure that.
It would be nice if there was a tapered rollar bearing tp replace these out dated rollar barrel bearings.
I went to Applied Ind.Tech and you can choose bearings by size but I didn't see where they dealt with any part numbers.
