    SKF 7415 seal cross references to 26-21642 upper crankcase seal
    I have replaced a lot of the raw hide seals from way back when with
    the 7415 What really matters is condition of crankshaft where seal lip rides
    It has to be smooth round and concentric to seal lip or it will not work.
    Sometimes a rebuild project has to put on hold awaiting a better crankshaft
