The seals consisted of two interlocking cork rings. One was tapered to the inside and the other tapered to the outside, pushing them together put pressure on the shaft to make the seal. A sort of internal aluminum snap ring held them in place. Sometimes backed up by a few yards of mono-filiment fish line. They were never much good. The same grease that kept the cork from wareing kept the aluminum ring from staying in place. If there is enough material in the casting, bore it out for a Chicago Rawhide seal to fit the shaft.
