Rear hubs

[Bob Culver]

When the felt seal and surface was unworn the inner hub would turn the same whether full on or not. . The outer ring of the race should be clamped axially. When apart it is worth assembling clean and checking the gap.The gasket of whatever should compress to less than this, although less critical at the rear than front.  (Or can add the two depths using a vernier calliper, and compare with the bearing plus washer. I dunno what the tolerance of the recesses are; one day I will go thru my hoard and compare)
