Super C fan hub and spindle

What type of seal is used to retain the oil in the fan hub.
Some type of packing material

NO shaft seal, for either the "Service Products" or the"Schwitzer-Cummins" fan hub.

(There ARE gaskets or a ring between the stack of parts that make them up, though.)

They used centrifugal force, as well as a spiral groove to "screw" the oil back inward. The oil level is BELOW the bore for the shaft so it doesn"t leak "at rest".

Do you know how to correctly fill and "check" the oil in them?
